The dynamics inherent to the life activity of all living systems presents itself in the form of regular patterns viewed by the observer as taking place in an extended timeline. Routines, rituals and celebrations, each in their own way, are defined by the typical cyclical behavioural patterns exhibited by individuals embedded in specific semiospheres. The particular nature of these semiospheres will determine the distinct patterns of behaviour to be adopted in different life contexts so that existential functions are fulfilled. The (...) restricted and protected family circle normally provides the initial learning environment where the definition of the individual’s Umwelt (von Uexküll 1909, 1934; Ferreira, Biosemiotics 3(1):107–130, 2010, 2011) his/her meaningful world, starts to take shape. This learning process comprehends the progressive identification of distinct physical entities, the development of basic patterns of physical and social behaviour- the incorporation of basic routines and the assignment of meaning to particular events.

This qualitative cross-sectional survey, undertaken in the antenatal booking clinics of a hospital in central London, explores pregnant women’s responses to routine HIV testing, examines their reasons for declining or accepting the test, and assesses how far their responses fulfil standard criteria for informed consent. Of the 32 women interviewed, only 10 participants were prepared for HIV testing at their booking interview. None of the women viewed themselves as being particularly at risk for HIV infection. The minority of the (...) participants who declined testing differed from those who accepted, by interpreting test acceptance as risky behaviour, privileging the negative outcomes of HIV positivity and expressing an inability to cope with these, should they occur. Troublingly, only a minority of women had a broad understanding of the rationale for the test, and none fulfilled the standard criteria for informed consent. This study suggests that, although routine screening combined with professional recommendation may be successful in increasing uptake, this may be at the cost of eroding informed consent. Protecting third parties from a preventable disease may outweigh the moral duty of respecting autonomy, enshrined in Western bioethical tradition. Nevertheless, such a policy should be made transparent, debated in the public domain and negotiated with women seeking antenatal care. (shrink)

Animal health is a key factor affecting the economic efficiency of the dairy industry. Improvements in animal health are also of relevance to society more broadly, given important implications for animal welfare, food safety and quality. Although the economic gains of best practice with regard to animal health have been well documented, many farmers are not adopting optimal herd management techniques. This paper utilises nationally representative farm-level data from Ireland for 2013 to identify drivers and barriers to the adoption of (...) best practice with regard to on-farm mastitis management. Exploratory factor analysis is used to derive measures of farmers’ attitudes towards animal health and mastitis and econometric techniques are employed to empirically assess the influence of these on the uptake of beneficial herd health management practices. A number of focus groups were also undertaken to complement the analysis. This paper concludes that farmers’ attitudes towards animal health are not a key driver in the uptake of best practice, although perceived disease risk is of relevance. A number of interesting issues arise in identifying barriers to the uptake of best practice, these include the possibility of routine inertia, i.e., farmers do not deviate from the routine developed around mastitis prevention until there is an indication of infection, as well as constraints around the availability of labour and time. Farmer behaviour with respect to mastitis management can thus be considered as reactionary as opposed to precautionary. This research highlights the valuable role of the extension agent but concludes that engagement around knowledge transfer and technology adoption is particularly complex. (shrink)

Although we tend to associate social transformation with major events, historical turning points, or revolutionary upheaval, Revolutionary Routines argues that seemingly minor everyday habits are the key to meaningful change. Through its account of influential socio-political processes – such as the resurgence of fascism and white supremacy, the crafting of new technologies of governance, and the operation of digital media and algorithms – this book rethinks not only how change works, but also what counts as change. Drawing examples from the (...) affective politics of Trumpism and Brexit, nudge theory and behaviour change, social media and the international refugee crisis, and the networked activism of Occupy and Black Lives Matter, Carolyn Pedwell argues that minor gestures may be as significant as major happenings, revealing the powerful potential in our ability to remake shared habits and imaginatively reinhabit everyday life. Revolutionary Routines offers a new understanding of the logics of habit and the nature of social change, power, and progressive politics, illustrating diverse forms of consciousness and co-operation through which political solidarities might take shape.

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children's complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution (...) System geared to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This “swamps” working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system's normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model.

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non‐deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual‐motor activity does not (...) have a privileged status with respect to memory. Soft constraints can work contrary to the designer's intentions by making the access of perfect knowledge in‐the‐world more effortful than the access of imperfect knowledge in‐the‐head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual‐motor effort of accessing knowledge in‐the‐world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in‐the‐head even when the absolute difference in perceptual‐motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design. (shrink)

We consider evidence for ritualized behavior in the sporting domain, noting that such behavior appears commonplace both before a competitive encounter and as part of pre-performance routines. The specific times when ritualized behaviors are displayed support the supposition that they provide temporary relief from pre-competition anxiety and act as thought suppressors in the moments preceding skill execution.

Norm theory (Kahneman & Miller, 1986) described a tendency for people to associate stronger regret with a negative outcome when it is a result of an exception (abnormal behavior) compared to when it is a result of routine (normal behavior). In two pre-registered studies, we conducted a replication and extension of three classic experiments on past behavior exception/routine contrasts (N = 684). We successfully replicated Kahneman and Miller’s (1986) experiments with the classic hitchhiker-scenario (Part 1) (...) and car accident-scenario (Part 2). In both cases, participants examined negative outcomes and tended to indicate a protagonist who deviated from own past behavior as more regretful than another who followed routine. Pre-registered extensions also showed effects for ratings of social norms, negative affect, and perceived luck. We did not find support for the Miller and McFarland (1986) experiment robbery scenario (Part 3) using a compensation measure, in that compensation to a victim of a robbery was not significantly different comparing exceptional and routine circumstances. However, a pre-registered extension showed that robbery under exceptional circumstances was regretted more than robbery under routine circumstances. We discuss implications for current and future research. (shrink)

We present a general framework for analyzing the contribution to reproductive success of a behavioural action. An action may make a direct contribution to reproductive success, but even in the absence of a direct contribution it may make an indirect contribution by changing the animal's state. We consider actions over a period of time, and define a reward function that characterizes the relationship between the animal's state at the end of the period and its future reproductive success. Working back from (...) the end of the period using dynamic programming, the optimal action as a function of state and time can be found. The procedure also yields a measure of the cost, in terms of future reproductive success, of a suboptimal action. These costs provide us with a common currency for comparing activities such as eating and drinking, or eating and hiding from predators. The costs also give an indication of the robustness of the conclusions that can be drawn from a model. We review how our framework can be used to analyze optimal foraging decisions in a stochastic environment. We also discuss the modelling of optimal daily routines and provide an illustration based on singing to attract a mate. We use the model to investigate the features that can produce a dawn song burst in birds. State is defined very broadly so that it includes the information an animal has about its environment. Thus, exploration and learning can be included within the framework. (shrink)

The Medication Event Monitoring System (MEMS) is a relatively new device designed to overcome some of the disadvantages of traditional adherence-measuring techniques. MEMS has also been found useful in tracking adherence behaviour without the need to visit patients frequently. In this study each patient was given a pre-filled, labelled MEMS bottle and cap. Patients were monitored for 24 weeks. For patients specifically studied, there were periods when drug levels may have been low and some exhibited erratic medication-taking behaviour. It is (...) concluded that MEMS can measure adherence behaviour objectively, and so might be used to improve prescribing decisions, identify drug wastage and improve carer support. Further research is needed before the routine use of electronic medication monitoring can be recommended. (shrink)

There is limited knowledge of the prevalence and nature of risky sexual behavior (RSB) among young adults in Hong Kong. This cross-sectional study explored the psychosocial risk factors of RSB with a sample of 1,171 Hong Kong university students (aged 18–40 years). Grounded in the theoretical propositions of several criminological theories (i.e., the theories of self-control, general strain, social learning, social control, and routine activity), engagement in three types of RSB (i.e., general, penetrative, and non-penetrative) was studied alongside (...) a range of psychosocial risk factors. Relative to female participants, male participants reported significantly higher mean levels of general, penetrative, and non-penetrative RSB. Male participants also reported significantly higher mean levels of negative temperament, use of alcohol and other drugs, and paraphilic interests than female participants, who reported significantly higher mean levels of self-control and social bonds than their male counterparts. The results of multivariate analyses (i.e., OLS regressions) revealed that, to a large extent, the male and female participants shared a similar set of psychosocial risk factors (i.e., use of alcohol and other drugs, and paraphilic interest) for their involvement in general, penetrative, and non-penetrative RSB. Furthermore, a high level of negative temperament was significantly associated with penetrative RSB for both genders, while a high level of perceived neighborhood disorganization was found to be an important factor in the participation of females in general, penetrative, and non-penetrative RSB. The findings of this study may have important implications for practice in regard to reducing, if not entirely preventing, the tendency to engage in RSB. (shrink)

Charney describes several mechanisms that will bias estimates of heritability in unpredictable directions. In addition, the mechanisms described by Charney explain the puzzling fact that research in human-behavior genetics routinely reports higher heritabilities than animal studies do. However, I argue that the concept of heritability has no real place in human research anyway.

Information-seeking behaviour of sniffer dogs during match-to-sample training in the scent lineup Qualitative and quantitative changes in dogs' information-seeking behaviours during the subsequent phases of operant conditioning training using a scent lineup, were investigated. Particular interest was paid to behaviours which may have an impact on errors committed by dogs at work in a scent lineup and thus on the reliability of the canine identification of humans on the base of scent. Significant individual differences were found in dogs' performance in (...) operant conditioning during match-to-sample trials. The style and time of sniffing the pattern scent sample as well as the searching time and number of stations sniffed in the lineup were found to influence the percentage of errors made by dogs. The effects of the dogs' routine e.g. omitting stations, using other cues than olfactory ones and effects of the non-verbal communications between handler and dog have been discussed. (shrink)

Since the onset of the COVID-19 pandemic, many parents have felt anxious, overwhelmed, and stressed out due to the changes in education and family and working routines. This work aimed to describe three dimensions of perceived parenting in the COVID-19 pandemic context, describe possible changes perceived by mothers in their children’s behavior during the social isolation phase, analyze if behavioral changes vary according to the dimension of perceived parenting, and analyze whether the characteristics of perceived parenting dimensions vary with (...) mother’s age, number of children and number of work hours. The purposive sample consisted of 646 mothers of school-aged children in Argentina. Questionnaires on sociodemographic and work-related data, and on children’s behavior were administered, as well as an instrument that assessed the three parenting dimensions. The sociodemographic and work-related variables of the study were described using descriptive statistics: measures of central tendency, frequencies, and percentages. The changes perceived in children’s behavior according to the reports given by the mothers regarding positive parenting, parenting stress, and school support were compared using the Mann Whitney’s U test, respecting the qualitative nature of the evaluated indicators. A factorial MANOVA was conducted to analyze the effect of mother’s age, ä number of children, and the number of work hours on parenting perceived by mothers. Parenting dimensions influenced the perceived children’s behavior. Mothers with higher positive parenting perceived more changes in their children’s behavior. In addition, those mothers who were more stressed out perceived more problems in almost all the measured behaviors than less stressed mothers. The mothers who reported to have provided more school support to their children perceived that they adapted better to online classes. Finally, mothers’ age and the number of children I parenting, particularly on parenting stress and school support, whereas work hours did not. A number of children affected stress and school support, and age only affected parenting stress. The only significant interaction regarding parenting was observed between the number of children and the number of work hours, which specifically affected parenting stress. Although social isolation due to COVID-19 affected children’s behavior, according to mothers, this might be partially linked to the number of children, mothers’ age, and the mothers’ parenting style. These initial findings may allow the identification of some protective factors and some risk factors of parenting in the Argentine context of a pandemic, and the design of preventive psychoeducational interventions to optimize the psychological wellbeing of families.

Representationalists have routinely expressed skepticism about the idea that inflexible responses to stimuli are to be explained in representational terms. Representations are supposed to be more than just causal mediators in the chain of events stretching from stimulus to response, and it is difficult to see how the sensory states driving reflexes are doing more than playing the role of causal intermediaries. One popular strategy for distinguishing representations from mere causal mediators is to require that representations are decoupled from specific (...) stimulus conditions. I believe this requirement on representation is mistaken and at odds with explanatory practices in sensory ecology. Even when sensory states have the job of coordinating a specific output with a specific input, we can still find them doing the work of representations, carrying information needed for organisms to respond successfully to environmental conditions. We can uncover information at work by intervening specifically on the information conveyed by sensory states, leaving their causal role undisturbed. (shrink)

Many autistic people are becoming increasingly involved in, and increasingly critical of, autism intervention research. They have expressed concerns regarding applied behavior analysis interventions on a number of grounds, one of which is the prevalence of conflicts of interests among autism intervention researchers. These concerns are now also being addressed by non-autistic researchers. COIs can introduce bias into the research process, and allow researchers to demonstrate positive effects for interventions that are not actually effective. Despite these concerns, there are (...) no studies to date that examine the prevalence of COIs in behavioral journals. Because ABA services are routinely provided to autistic people in the United States as a means to address difficulties experienced by autistic people, this is an important area of investigation. We tallied author COIs in articles published over a 1-year period that tested, commented on, or reviewed ABA autism intervention strategies, extracted from eight journals devoted to publishing behavioral research. We coded included studies for COIs related to researcher employment as an ABA clinical provider or a training consultant to ABA clinical providers. We found that 84% of studies had at least one author with this type of COI, but they were only disclosed as COIs in 2% of studies. Additionally, 87% of studies with statements claiming the authors did not have COIs, were authored by researchers found to have clinical/training consultancy COIs. Pervasive, undisclosed COIs likely lead to researcher bias, and could at least partially account for persistent poor quality research in this area. The high prevalence of COIs among this research corroborates the concerns expressed by many autistic people. The autism community – including autistic people, autism researchers, and other stakeholders – should be aware of the prevalence of undisclosed COIs in this literature and take this into account when using, providing, or recommending ABA services.

The theory of ritualized behavior should offer insight about cultural rituals. Considering ritualized behaviors' scripted actions and both the frequent absence of anxiety and the routinization of many cultural rituals, questions remain about how much and what precisely gets explained. Among religious rituals, ritualized behaviors arise more strikingly in special agent rituals, but that might be because they usually include novices. (Published Online February 8 2007).

Restricting a person’s liberty presents society with many inherent ethical challenges. The historical purposes of confinement have included punishment, penitence, containment, rehabilitation, and habilitation. While the purposes are indeed complex, multifaceted, and at times ambiguous or contradictory, the fact of incarceration intrinsically creates many ethical challenges for psychiatrists working in correctional settings. Role definition of a psychiatrist may be ambiguous, with potential tensions between forensic and therapeutic demands. Privacy may be limited or absent and confidentiality may be compromised. Patient autonomy (...) may be threatened to address real or perceived security concerns. Care delivery may actually have harmful consequences in court cases for pretrial detainees or lethal consequences for those under a death sentence. An absence of data and targeted research hampers the development of evidence-based care delivery for the disenfranchised, understudied, and disproportionately ill prisoner population. In this review paper, I discuss a few of the challenges and dilemmas routinely faced and present a series of questions. Where feasible, proposed resolutions are offered. (shrink)

The study of expertise is difficult to do in a laboratory environment due to the challenge of finding people at different skill levels and the lack of time for participants to acquire mastery. In this paper, we report on two studies that analyze naturalistic gameplay data using cohort analysis to better understand how skill relates to practice and habit. Two cohorts are analyzed, each from two different games. Our work follows skill progression through 7 months of Halo matches for a (...) holistic perspective, but also explores low-level in-game habits when controlling game units in StarCraft 2. Players who played moderately frequently without long breaks were able to gain skill the most efficiently. What set the highest performers apart was their ability to gain skill more rapidly and without dips compared to other players. At the beginning of matches, top players habitually warmed up by selecting and re-selecting groups of units repeatedly in a meaningless cycle. They exhibited unique routines during their play that aided them when under pressure. (shrink)

The "morning morality effect"-the alleged phenomenon that people are more likely to act in unethical ways in the afternoon when they are tired and have less self-control than in the morning-may well be expected to influence prehospital anaesthesiologist manning mobile emergency care units (MECUs). The working conditions of these units routinely entail fatigue, hunger, sleep deprivation and other physical or emotional conditions that might make prehospital units predisposed to exhibit the "morning morality effect". We investigated whether this is in fact (...) the case by looking at the distribution of patient transports to hospital with and without physician escort late at night at the end of the shift as a surrogate marker for changing thresholds in ethical behaviour. All missions over a period of 11 years in the MECU in Odense were reviewed. Physician-escorted transports to hospital were compared with non-physician-escorted transports during daytime, evening, and night-time (which correlates with time on the 24 h shifts). In total, 26,883 patients were transported to hospital following treatment by the MECU. Of these, 27.4% (26.9%-27.9%) were escorted to the hospital. The ratio of patient transports to hospital with and without physician escort during the three periods of the day did not differ (p = 1.00). We found no evidence of changes in admission patterns over the day. Thus, no evidence of the expected "morning morality effect" could be found in a prehospital physician-manned emergency care unit.

A critical aspect of much human behaviour is the generation and regulation of sequential activities. Such behaviour is seen in both naturalistic settings such as routine action and language production and laboratory tasks such as serial recall and many reaction time experiments. There are a variety of computational mechanisms that may support the generation and regulation of sequential behaviours, ranging from those underlying Turing machines to those employed by recurrent connectionist networks. This paper surveys a range of such mechanisms, (...) together with a range of empirical phenomena related to human sequential behaviour. It is argued that the empirical phenomena pose difficulties for most sequencing mechanisms, but that converging evidence from behavioural flexibility, error data arising from when the system is stressed or when it is damaged following brain injury, and between-trial effects in reaction time tasks, point to a hybrid symbolic activation-based mechanism for the generation and regulation of sequential behaviour. Some implications of this view for the nature of mental computation are highlighted. (shrink)

Given that domestication provided animals with more stable environmental conditions, artificial selection by humans has likely affected animals' ability to learn novel contingencies and their ability to adapt to changing environments. In addition, the selection for specific traits in domestic animals might have an additional impact on subjects' behavioural flexibility, but also their general learning performance, due to a re-allocation of resources towards parameters of productivity. To test whether animals bred for high productivity would experience a shift towards lower learning (...) performance, we compared the performance of dwarf goats and dairy goats in a visual discrimination learning and reversal learning task. Goats were tested individually in a test compartment and were rewarded by choosing either a white or a black cup presented by the experimenter on a sliding board behind a crate. Once they reached a designated learning criterion in the initial learning task, they were transferred to the reversal learning task. To increase the heterogeneity of our test sample, data was collected by two experimenters at two research stations following a similar protocol. Goats of both selection lines did not differ in the initial discrimination learning task in contrast to the subsequent reversal learning task. Dairy goats reached the learning criterion slower compared to dwarf goats. Our results may indicate that the selection for milk production might have affected behavioural flexibility in goats. These differences in adapting to changing environmental stimuli might have an impact on animal welfare e.g., when subjects have to adapt to new environments or changes in housing and management routines.

Philosophical arguments stemming from the public health ethics arena suggest that public health interventions ought to be subject to normative inquiry that considers relational values, including concepts such as solidarity, reciprocity and health equity. As yet, however, the extent to which ‘public’ values influence the ‘autonomous’ decisions of the public remains largely unexplored. Drawing on interviews with 50 men in Vancouver, Canada, this study employs a critical discourse analysis to examine participants’ decisions and motivations to voluntarily access HIV testing and/or (...) to accept a routine HIV test offer. Within a sub-set of interviews, a transactional discourse emerged in which the decision to test features an arrangement of ‘giving and receiving’. Discourses related to notions of solidarity emphasize considerations of justice and positions testing as a ‘public’ act. Lastly, ‘individualistic’ discourses focused on individual-level considerations, with less concern for the broader public ‘good’. These findings underscore how normative dimensions pertaining to men’s decisions to test are dialectically interrelated with the broader social and structural influences on individual and collective health-related behaviour, thereby suggesting a need to advance an explicit empirical-normative research agenda related to population and public health intervention research.

Animals routinely adapt to changes in the environment in order to survive. Though reinforcement learning may play a role in such adaptation, it is not clear that it is the only mechanism involved, as it is not well suited to producing rapid, relatively immediate changes in strategies in response to environmental changes. This research proposes that counterfactual reasoning might be an additional mechanism that facilitates change detection. An experiment is conducted in which a task state changes over time and the (...) participants had to detect the changes in order to perform well and gain monetary rewards. A cognitive model is constructed that incorporates reinforcement learning with counterfactual reasoning to help quickly adjust the utility of task strategies in response to changes. The results show that the model can accurately explain human data and that counterfactual reasoning is key to reproducing the various effects observed in this change detection paradigm. (shrink)

Understanding the nature of errors in a simple, rule‐based task—programming a VCR—required analyzing the interactions among human cognition, the artifact, and the task. This analysis was guided by least‐effort principles and yielded a control structure that combined a rule hierarchy task‐to‐device with display‐based difference‐reduction. A model based on this analysis was used to trace action protocols collected from participants as they programmed a simulated VCR. Trials that ended without success (the show was not correctly programmed) were interrogated to yield insights (...) regarding problems in acquiring the control structure. For successful trials (the show was correctly programmed), steps that the model would make were categorized as matches to the model; steps that the model would not make were violations of the model. The model was able to trace the vast majority of correct keystrokes and yielded a business‐as‐usual account of the detection and correction of errors. Violations of the model fell into one of two fundamental categories. The model provided insights into certain subcategories of errors; whereas, regularities within other subcategories of error suggested limitations to the model. Although errors were rare when compared to the total number of correct actions, they were important. Errors were made on 4% of the keypresses that, if not detected, would have prevented two‐thirds of the shows from being successfully recorded. A misprogrammed show is a minor annoyance to the user. However, devices with the approximate complexity of a VCR are ubiquitous and have found their way into emergency rooms, airplane cockpits, power plants, and so on. Errors of ignorance may be reduced by training; however, errors in the routine performance of skilled users can only be reduced by design. (shrink)

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck or the withers for three consecutive weeks, the third group was exposed to close visual presence. After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in stepping during rectal palpation, which occurred less often in Neck- and (...) Withers-animals than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation.

The practice of generalist medicine differs from the practice of other clinical disciplines. We postulate that the application of ethics in generalist practice similarly differs from its application in other healthcare settings. In contrast to the problem- focused practice of ethics in other medical specialties, the practice of ethics in generalist medicine blends habits of mind with behaviors applied routinely over time—an ethical way of being. Using a graphic summary and tabular matrix, we present five “T” habits of mind (time, (...) talk, tact, touch, and trust), associate them with applicable practice characteristics, and link them to observable clinician behaviors to demonstrate how the application of ethics in generalist practice is a day-to-day endeavor and not simply a means to resolve episodic conflicts. We textually review key aspects of the matrix and present two case studies that illustrate how such habits of mind and practice behaviors inform the ethical way of being we espouse. We invite generalist practitioners to incorporate the five “T” habits and associated behaviors into their daily care of patients, and we encourage clinical ethicists and other clinical faculty members to consider using them as a model for ethics education with medical students and resident physicians.

Routine action sequences critically rely on neural mechanisms maintaining contextual and temporal information to disambiguate similar tasks (e.g. making coffee or tea). In this study we show the involvement of areas in temporal and lateral prefrontal cortices in maintaining temporal and contextual information for the execution of hierarchically‐organized action sequences.

Traditional mechanistic accounts of language processing derive almost entirely from the study of monologue. Yet, the most natural and basic form of language use is dialogue. As a result, these accounts may only offer limited theories of the mechanisms that underlie language processing in general. We propose a mechanistic account of dialogue, the interactive alignment account, and use it to derive a number of predictions about basic language processes. The account assumes that, in dialogue, the linguistic representations employed by the (...) interlocutors become aligned at many levels, as a result of a largely automatic process. This process greatly simplifies production and comprehension in dialogue. After considering the evidence for the interactive alignment model, we concentrate on three aspects of processing that follow from it. It makes use of a simple interactive inference mechanism, enables the development of local dialogue routines that greatly simplify language processing, and explains the origins of self-monitoring in production. We consider the need for a grammatical framework that is designed to deal with language in dialogue rather than monologue, and discuss a range of implications of the account. Key Words: common ground; dialogue; dialogue routines; language comprehension; language production; monitoring; perception-behavior link. (shrink)

Julia Annas proposes to shed light on the intelligence of virtue through an analogy with the intelligence of practical skills. To do so, she first aims to distinguish genuine skills and skillful actions from mere habits and routine behaviour: like skills, habits are acquired through habituation and issue in action immediately (i.e. unmediated by reasoning about what to do), but the routine behaviour in which habit issues is mindless and unintelligent, and cannot serve to establish or illuminate the (...) intelligence of virtuous action. In a second step, she argues that virtue has the same kind of intellectual structure—and is acquired through the same kind of habituation—as skill. I argue that Annas’s proposal fails at the first step: her conceptions of the rational articulacy of skill and the immediacy that characterizes its exercise in action cannot be squared. I offer an alternative conception of the intelligence of skill and its exercise that draws on Aristotle’s conception of rational capacities as two-way powers. But as a virtue is not a two-way power, virtues and skills do not share a common intellectual structure. (shrink)

Ongoing developments in the field of synthetic biology are pursuing the re-organisation and control of biological components to make functional devices.

The differentiation between noise and randomness in its constructive role, that is, between noise (...) as a perturbation in routine behaviours and noise as a source of variability that cells may exploit, indicates the need for a clarification and rectification of the conflicting uses of the notion of noise in the studies of the so-called noise biology.

I was, at first sight, puzzled by this puzzlement.There is no question that we, indeed, are ignorant of many of our reasons. (...) In cases of routine behavior, for instance, we are often not, or only dimly, aware of the reasons for doing something. When I use the indicator when taking a turn to the left with my car, I have no conscious reason for doing so. It has become routine behavior, acquired during my lessons in car driving. My non-awareness may even be considered as sign of my excellence as a driver. This non-awareness is most noteworthy in all those cases in which we, again routinely, withdraw from a particular action. Education and training not only teach us how and why to perform certain activities, they also give us reasons to refrain from all sorts of other actions. There are many reasons to do certain things; there seem to be many more reasons for not doing other things. To suppose that having reasons would by necessity involve conscious awareness of these reasons would life make impossible to live.So, ignorance seems to be very common, not to say trivial. This raises the question whether there is anything nontrivial in the attempt to make sense of ignorance of our reasons. What element or aspect of ignorance is it that may evoke philosophical interest? Jennifer Church seems to have in mind different overlapping concerns. In the first part of her paper, she addressesthe issue of legitimacy; that is, the specification of conditions under which attributions of unconscious content are legitimate or illegitimate; andthe issue of normativity; that is, the question how and why unconscious reasons can be normative for me.The first question can be discussed without reference to a self; the second question cannot. In the second part of the paper there arise new concerns:the issue of having reasons that can not be recognized as reasons by oneself, "strange reasons" so to say, with spatial reasoning as a paradigm case; andthe issue of being moved by ones reasons through the visceral connection between desires and beliefs on the one hand and motor activity (external or internal) on the other hand; this connection is secured by our emotions.[End Page 49] Recapitulation Let me try to recapitulate some of the main issues. Church makes, first, a distinction between having access to one's reasons and recognizing one's reasons as reasons. She proceeds by discussing the no-access problem in terms of a functionalist metaphysics of mental states. Then she suggests that ascribing unconscious content (or reason) to a person, in fact, boils down to the evaluation of the appropriateness of the ascription of a specimen of practical reasoning to the subject. Practical reasoning involves the structured connection and interaction between beliefs and desires. This structure can be studied at the level of animal psychology; however, there are some important differences between humans and animals: humans can withhold assent, they can lie, and they may recognize mistakes, whereas animals cannot. The possibility of being mistaken about one's reasons leads from the issue of legitimacy to the issue of normativity. For a reason to become my reason, the belief–desire network should make sense, I should feel normatively compelled in some way. So the issue of normativity cannot be studied apart from the possibility of recognition. To recognize a reason as one's reason, one has—at some level of understanding—to assent with its content, even if this occurs implicitly.In the second part the conditions for recognition are investigated in the form of an analysis of unconscious reasons that are strange. Strange reasons are not recognized because they function in some different way compared to normal conscious reasoning. Strangeness is defined here in terms of a different way of... (shrink)

States of affairs are considered as ontologically basic. Different from similar accounts, these states of affairs are introduced as simple occurrences or items of a certain kind. The ontological importance of these occurrences lies in their semantical function as exemplars for the introduction of the most basic linguistic devices. The ontological basis proposed is particularist. Universals are an aspect of our routine behaviour as we neglect the differences of particular properties of things. Abstract objects are produced in our (...) class='Hi'>routine, language-dependent operations if we leave aside the fact that we usually operate with some definite material. (shrink)

In this two-part article, I propose a new materialist understanding of behavior. The term “mattering” in the title refers to sense-making behavior that matters, that is, to significant habits and materialized behaviors. By significant habits I mean protocols, practices and routines that generate ways of reading material signs and fixed accounts of movement. I advance a notion of behaving that stresses its materiality and sensory shaping, and I provide select examples from music. I note that current definitions of (...) behavior do not capture its material dimension. This is because behavioral science has mostly viewed matter as passive, and not as an active agency. Such an approach has metaphysically framed behavior as a phenomenon of presence that is external from its environment. The approach of behavioral science to matter where there are fixed borders between the internal and external is lacking, since it does not account for agential cuts as conceptualized by Karen Barad. Instead, I consider behavior performatively; as an ongoing iterative practice and as integral to the growth of immanently self-caused matter that spawns metastable relational formations that produce different possibilities for successive formations. In this regard, behavior matters, and matter behaves. One key aspect of my article advances Bernard Stiegler as a critical new materialist thinker. This advancement concerns the technical doings of artworks, which include the material activity that is generative of sensitivity: feelings and beliefs associated with a sense or meaning. I outline an example of the materiality of habits as constitutive of music. After that, I coin the transformative doings of matter on the artist as a “caripulation,” which is a desired movement or motion that transforms the mover and the moved. Finally, I raise “pharmacological” considerations in terms of the Stieglerian aspects of organic and inorganic organized matter. (shrink)

Resilience may be referred to as the capacity for positive adaptation and to quickly recover from difficulties and significant adversity. After examining operational definitions of related concepts, the article discusses resilience building exercises for functional fitness at the individual soldier level, to include among others, self-monitoring, self-evaluation, self-reinforcement, emotional regulation exercises, mindfulness training, relaxation and grounding exercises and importance of maintaining discipline and routine in the military. Using an acronym CARRIES, the article examines efforts to enhance resilience building through (...) empirically validated cognitive, behavioural and intrapersonal skills originating from best practices learned in the military.

This book is based on arguments presented in Achtenberg’s 1982 doctoral dissertation and several of her recent articles. In this book, Achtenberg forcefully and convincingly argues that a crucial connection exists between Aristotle’s metaphysics and ethics and that Aristotle’s ethics can be read on two levels—“in terms of its imprecise but fully justified claims,” or “in terms of the more precise metaphysical, physical, and psychological principles and arguments consideration of which gives the ethics greater articulation or depth”. She argues that (...) ethical virtue and emotions for Aristotle are cognitive: they involve cognition, not simply of particulars, but of the value of the particulars. In this, Achtenberg presents a sort of value realism that is, paradoxically, relative and relational at the same time. For Aristotle, she contends, “there are two principal types of value,” “the good and the beautiful”. The good is an analogical equivocal, that is, an imprecise universal that shares some important similarity among its instantiations but will show up in the particulars in varied and oftentimes wholly unexpected ways. Achtenberg further argues that the good and the beautiful can be understood in terms of metaphysical concepts of telos, entelecheia, or energeia of a thing, a person, or an act because telos is what makes a thing complete, truly being “what it is.” In sum, “[a] telos is a principle of preservation or enrichment” for the things of which it is the telos, just as sight is the telos of the eyes, and virtue is “energeia of the soul”. Although telos sets a limit concerning what is to be done and what is not, it is the kind of limit that is properly called “constitutive limit” as opposed to harmful or destructive limit. Ethical virtue, friendship, and just government are examples of telos as constitutive limitation because they make the subjects that possess them flourish, whereas moral vice, animosity, and unjust government are examples of destructive limitation. In light of this, Achtenberg offers a new interpretation of the Aristotelian “mean,” which denotes neither a trivial middling amount nor an uninspiring routinized behavior, but what is “the appropriate or the needed” in each situation. She concludes that, contrary to many other moral theorists, Aristotle’s appreciation of the perception of the value of the particulars as constituents of a flourishing life is an example of “imaginative construction” that makes parts meaningful in light of the whole, rather than an imaginative deconstruction that reduces a whole into senseless parts. She sums up the book by providing an assessment of Aristotle’s ethics in terms of its strengths and weaknesses. (shrink)

Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed (...) to protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis, we show here in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses. These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.

Behavioral scientists routinely publish broad claims about human psychology and behavior in the world's top journals based on samples drawn entirely from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Researchers – often implicitly – assume that either there is little variation across human populations, or that these “standard subjects” are as representative of the species as any other population. Are these assumptions justified? Here, our review of the comparative database from across the behavioral sciences suggests both that there (...) is substantial variability in experimental results across populations and that WEIRD subjects are particularly unusual compared with the rest of the species – frequent outliers. The domains reviewed include visual perception, fairness, cooperation, spatial reasoning, categorization and inferential induction, moral reasoning, reasoning styles, self-concepts and related motivations, and the heritability of IQ. The findings suggest that members of WEIRD societies, including young children, are among the least representative populations one could find for generalizing about humans. Many of these findings involve domains that are associated with fundamental aspects of psychology, motivation, and behavior – hence, there are no obviousa priorigrounds for claiming that a particular behavioral phenomenon is universal based on sampling from a single subpopulation. Overall, these empirical patterns suggests that we need to be less cavalier in addressing questions ofhumannature on the basis of data drawn from this particularly thin, and rather unusual, slice of humanity. We close by proposing ways to structurally re-organize the behavioral sciences to best tackle these challenges. (shrink)

Humans routinely make inferences about both the contents and the workings of other minds based on observed actions. People consider what others want or know, but also how intelligent, rational, or attentive they might be. Here, we introduce a new methodology for quantitatively studying the mechanisms people use to attribute intelligence to others based on their behavior. We focus on two key judgments previously proposed in the literature: judgments based on observed outcomes (you're smart if you won the game) (...) and judgments based on evaluating the quality of an agent's planning that led to their outcomes (you're smart if you made the right choice, even if you didn't succeed). We present a novel task, the maze search task (MST), in which participants rate the intelligence of agents searching a maze for a hidden goal. We model outcome‐based attributions based on the observed utility of the agent upon achieving a goal, with higher utilities indicating higher intelligence, and model planning‐based attributions by measuring the proximity of the observed actions to an ideal planner, such that agents who produce closer approximations of optimal plans are seen as more intelligent. We examine human attributions of intelligence in three experiments that use MST and find that participants used both outcome and planning as indicators of intelligence. However, observing the outcome was not necessary, and participants still made planning‐based attributions of intelligence when the outcome was not observed. We also found that the weights individuals placed on plans and on outcome correlated with an individual's ability to engage in cognitive reflection. Our results suggest that people attribute intelligence based on plans given sufficient context and cognitive resources and rely on the outcome when computational resources or context are limited.

There are things we routinely say that may strike us as literally false but that we are nonetheless reluctant to give up. This might be something mundane, like the way we talk about the sun setting in the west, or it could be something much deeper, like engaging in talk that is ostensibly about numbers despite believing that numbers do not literally exist. Rather than regard such behaviour as self-defeating, a "fictionalist" is someone who thinks that this kind of discourse (...) is entirely appropriate, even helpful, so long as we treat what is said as a useful fiction, rather than as the sober truth. "Fictionalism" can be broadly understood as a view that uses a notion of pretense or fiction in order to resolve certain puzzles or problems that otherwise do not necessarily have anything to do with literature or fictional creations. Within contemporary analytic philosophy, fictionalism has been on the scene for well over a decade and has matured during that time, growing in popularity. There are now myriad competing views about fictionalism and consequently the discussion has branched out into many more subdisciplines of philosophy. Yet there is widespread disagreement on what philosophical fictionalism actually amounts to and about how precisely it ought to be pursued. This volume aims to guide these discussions, collecting some of the most up-to-date work on fictionalism and tracing the view's development over the past decade. After a detailed discussion in the book's introductory chapter of how philosophers should think of fictionalism and its connection to metaontology more generally, the remaining chapters provide readers with arguments for and against this view from leading scholars in the fields of epistemology, ethics, metaphysics, philosophy of science, philosophy of language, and others.

We routinely need to process the identity of many faces around us, and how the brain achieves this is still the subject of much research in cognitive neuroscience. To date, insights on face identity processing have come from both healthy and clinical populations. However, in order to directly compare results across and within participant groups, and across different studies, it is crucial that a standard task is utilised which includes different exemplars (for example, non-face stimuli along with faces), is memory-neutral, (...) and taps into identity recognition across orientation and across viewpoint change. The goal of this study was to test a previously behaviourally tested, optimised face and object identity matching design in a healthy control sample whilst being scanned using fMRI. Specifically, we investigated categorical, orientation, and category-specific orientation effects while participants were focused on identity processing of simultaneously presented exemplar stimuli. Alongside observing category and orientation specific effects in a distributed set of brain regions, we also saw an interaction between stimulus category and orientation in the bilateral fusiform gyrus and bilateral middle occipital gyrus. Generally these clusters showed the pattern of a heightened response to inverted, as opposed to upright faces; and to upright, as opposed to inverted shoes. These results are discussed in relation to previous studies and to potential future research within prosopagnosic individuals. (shrink)

Humans routinely modify their walking speed to adapt to functional goals and physical demands. However, damage to the central nervous system often results in abnormal modulation of walking speed and increased risk of falls. There is considerable interest in treatment modalities that can provide safe and salient training opportunities, feedback about walking performance, and that may augment less reliable sensory feedback within the CNS after injury or disease. Fully immersive virtual reality technologies show benefits in boosting training-related gains in walking (...) performance; however, they lack views of the real world that may limit functional carryover. Augmented reality and mixed reality head-mount displays provide partially immersive environments to extend the virtual reality benefits of interacting with virtual objects but within an unobstructed view of the real world. Despite this potential advantage, the feasibility of using MR-HMD visual feedback to promote goal-directed changes in overground walking speed remains unclear. Thus, we developed and evaluated a novel mixed reality application using the Microsoft HoloLens MR-HMD that provided real-time walking speed targets and augmented visual feedback during overground walking. We tested the application in a group of adults not living with disability and examined if they could use the targets and visual feedback to walk at 85%, 100%, and 115% of each individual’s self-selected speed. We examined whether individuals were able to meet each target gait speed and explored differences in accuracy across repeated trials and at the different speeds. Additionally, given the importance of task-specificity to therapeutic interventions, we examined if walking speed adjustment strategies were consistent with those observed during usual overground walking, and if walking with the MR-HMD resulted in increased variability in gait parameters. Overall, participants matched their overground walking speed to the target speed of the MR-HMD visual feedback conditions. The percent inaccuracy was approximately 5% across all speed matching conditions and remained consistent across walking trials after the first overall walking trial. Walking with the MR-HMD did not result in more variability in walking speed, however, we observed more variability in stride length and time when walking with feedback from the MR-HMD compared to walking without feedback. The findings offer support for mixed reality-based visual feedback as a method to provoke goal-specific changes in overground walking behavior. Further studies are necessary to determine the clinical safety and efficacy of this MR-HMD technology to provide extrinsic sensory feedback in combination with traditional treatments in rehabilitation.

Typicality is routinely invoked in everyday contexts: bobcats are typically short-tailed; people are typically less than seven feet tall. Typicality is invoked in scientific contexts as well: typical gases expand; typical quantum systems exhibit probabilistic behaviour. And typicality facts like these support many explanations, both quotidian and scientific. But what is it for something to be typical? And how do typicality facts explain? In this paper, I propose a general theory of typicality. I analyse the notion of a typical property. (...) I provide a formalism for typicality explanations, and I give an account of why typicality explanations are explanatory. Along the way, I show how typicality facts explain a variety of phenomena, from everyday phenomena to the statistical mechanical behaviour of gases. Finally, I argue that typicality is not the same thing as probability. (shrink)
