To carry out an ethnographic study on the work process in the sterilization unit of a hospital in Catalonia, we found the socially distributed cognition approaches of Hutchins and Kirsh useful. However, these approaches lack sufficient explanation on three important issues: the pragmatic criteria for identifying and delimiting a relevant unit of analysis and therefore the setting and contexts of the work process; the mechanisms and results of reciprocal influences between these levels of analysis; and the relation (...) between these levels. Therefore, we added several new elements to these approaches, in addition to Layder's model of contexts with some important modifications, with the aim of offering an interactive, cognitive and social proposal of analysis that clarifies these three issues, allowing a more exhaustive and broader empirical analysis that captures better the ‘social’ dimension embedded in the work processes.

Cognitive processes, cognitive psychology tells us, unfold in our heads. In contrast, several approaches in cognitive engineering argue for a shift of unit of analysis from what is going on in the heads of operators to the workings of whole socio-technical systems. This shift is sometimes presented as part of the development of a new understanding of what cognition is and where the boundaries of cognitive systems are. Cognition, it is claimed, is not just situated or embedded, (...) but extended and distributed in the world. My main question in this article is what the practical significance is of this framing of an expanded unit of analysis in a cognitive vocabulary. I focus on possible consequences for how cognitive engineering practitioners think about function allocation in system design, and on what the relative benefits and costs are of having a common framework and vocabulary for talking about both human and technical system components. I argue for what I call an *expansive but deflated conception of cognition*, primarily on pragmatic grounds. In addition, I claim that the important lesson of the “boundaries of cognition” debate in cognitive science is the negative claim that there is not anything special about the biological boundary of the skin and skull per se, rather than some positive claim about where the boundaries of extended or distributed cognitive systems really are. I also examine the role of the concept of cognition in the theoretical frameworks of distributed cognition, joint cognitive systems (also known as cognitive system engineering), and cognitive work analysis.

We suggest a common ground for alternative proposals In different domains of cognitive science which have previously seemed to have little in common. The underlying common theme is associated with a redefinition of the basic unit of analysis in each domain of thought. Our framework suggests a definition of unity which is based not on inherent properties of the elements constituting the unit, but rather on dynamic patterns of correlation across the elements. We introduce a set of features that (...) characterize the new dynamic units, and distinguish them from traditional units of analysis. A conceptual connection is made with the identification of elementary units in modern physics theories, as well as with concepts and structures in the study of complex dynamical systems and connectionism. The paper analyses the evolution of the concept of unit in different domains of thought in cognitive science, and examines the proposed framework of “dynamic unity” with regard to various theoretical problems within each domain. The particular cognitive science issues discussed in the paper include: (1) the binding problem in the brain; (2) the mental unit of conceptual organization; (3) defining ‘wordhood’ in linguistics; and (4) identifying the unit of cognition in the natural environment.

The “erasing race” effect is the reduction of the salience of “race” as an alliance cue when recalling coalition membership, once more accurate information about coalition structure is presented. We conducted a random-effects model meta-analysis of this effect using five United States studies (containing nine independent effect sizes). The effect was found (ρ = 0.137, K = 9, 95% CI = 0.085 to 0.188). However, no decline effect or moderation effects were found (a “decline effect” in this context would (...) be a decrease in the effect size over time). Furthermore, we found little evidence of publication bias. Synthetically correcting the effect size for bias stemming from the use of an older method for calculating error base rates reduced the magnitude of the effect, but the it remained significant. Taken together, these findings indicate that the “erasing race” effect generalizes quite well across experimental contexts and would, therefore, appear to be quite robust. We reinterpret the theoretical basis for these effects in line with Brunswikian evolutionary-developmental theory and present a series of predictions to guide future research in this area. (shrink)

This article addresses the issue of units of analysis and atomistic models in psychology taking creativity research as a case study. A classic typology in this area, initially proposed by Rhodes, distinguishes between the four P's of creativity: person, process, product, and press. Continuing an effort to rewrite this basic language of the discipline from a cultural psychological perspective in the form of five A's, the discussion here focuses on bringing relationships to the fore within this framework and (...) problematising strict distinctions between each of the five elements. A closer look at the five A's of creativity, drawing on theoretical considerations and illustrated by interviews with creators working in different domains, reveals the permeable borders surrounding these units and challenges clear divisions between actors and audiences, action and artefacts, actors and artefacts. In the end, it is argued that creative phenomena cannot be properly understood and studied outside of their integrated and dynamic totality defined as a creativity complex. Implications of adopting this “molecular” perspective for theory and methodology are discussed. (shrink)

Most studies on Ibn Khaldūn have emphasized the similarities between his thought and the ideas and models of the modern social sciences. It is these similarities and parallels that lie at the root of the high esteem in which he is held in both the East and the West today. But the differences between his thought and the modern social sciences are perhaps more fecund, offering a new window onto the great thinker with the potential to improve our understanding of (...) the man and to reveal alternative frameworks to the entrenched social-scientific models of our age.In this context, one of the most noteworthy characteristics of Ibn Khaldūn's thought, and one that distinguishes it from mainstream...

Cognitive ecology is the study of cognitive phenomena in context. In particular, it points to the web of mutual dependence among the elements of a cognitive ecosystem. At least three fields were taking a deeply ecological approach to cognition 30 years ago: Gibson’s ecological psychology, Bateson’s ecology of mind, and Soviet cultural-historical activity theory. The ideas developed in those projects have now found a place in modern views of embodied, situated, distributed cognition. As cognitive theory continues to shift (...) from units of analysis defined by inherent properties of the elements to units defined in terms of dynamic patterns of correlation across elements, the study of cognitive ecosystems will become an increasingly important part of cognitive science.

Background:Moral courage is defined as courage to act according to one’s own ethical values and principles even at the risk of negative consequences for the individual. In a complex nursing practice, ethical considerations are integral. Moral courage is needed throughout nurses’ career.Aim:To analyse graduating nursing students’ moral courage and the factors associated with it in six European countries.Research design:A cross-sectional design, using a structured questionnaire, as part of a larger international ProCompNurse study. In the questionnaire, moral courage was assessed with (...) a single question (visual analogue scale 0–100), the questionnaire also covered several background variables.Participants and research context:The sample comprised graduating nursing students (n = 1796) from all participating countries. To get a comprehensive view about graduating nursing students’ moral courage, the views of nurse managers (n = 538) and patients (n = 1327) from the same units in which the graduating nursing students practised were also explored, with parallel questionnaires.Ethical considerations:Ethical approvals and research permissions were obtained according to national standards in every country and all participants gave their informed consent.Results:The mean of graduating nursing students’ self-assessed moral courage was 77.8 (standard deviation 17.0; on a 0–100 scale), with statistically significant differences between countries. Higher moral courage was associated with many factors, especially the level of professional competence. The managers assessed the graduating nursing students’ moral courage lower (66.5; standard deviation 18.4) and the patients slightly higher (80.6; standard deviation 19.4) than the graduating nursing students themselves.Discussion and conclusions:In all countries, the graduating nursing students’ moral courage was assessed as rather high, with differences between countries and populations. These differences and associations between moral courage and ethics education require further research. (shrink)

Doctoral programs at U.S. universities play a critical role in the development of human resources both in the United States and abroad. This volume reports the results of an extensive study of U.S. research-doctorate programs in five broad fields: physical sciences and mathematics, engineering, social and behavioral sciences, biological sciences, and the humanities. Research-Doctorate Programs in the United States documents changes that have taken place in the size, structure, and quality of doctoral education since the widely used 1982 editions. This (...) update provides selected information on nearly 4,000 doctoral programs in 41 subdisciplines at 274 doctorate-granting institutions. This volume also reports the results of the National Survey of Graduate Faculty, which polled a sample of faculty for their views on the scholarly quality of program faculty and the effectiveness of doctoral programs in preparing research scholars/scientists. This much-anticipated update of such an essential reference will be useful to education administrators, university faculty, and students seeking authoritative information on doctoral programs.

The social sciences playa variety of multifaceted roles in the policymaking process. So varied are these roles, indeed, that it is futile to talk in the singular about the use of social science in policymaking, as if there were one constant relationship between two fixed and stable entities. Instead, to address this issue sensibly one must talk in the plural about uses of dif ferent modes of social scientific inquiry for different kinds of policies under various circumstances. In some cases, (...) the influence of social scientific research is direct and tangible, and the connection between the find ings and the policy is easy to see. In other cases, perhaps most, its influence is indirect-one small piece in a larger mosaic of politics, bargaining, and compromise. Occasionally the findings of social scientific studies are explicitly drawn upon by policymakers in the formation, implementation, or evaluation of particular policies. More often, the categories and theoretical models of social science provide a general background orientation within which policymakers concep tualize problems and frame policy options. At times, the in fluence of social scientific work is cognitive and informational in nature; in other instances, policymakers use social science primarily for symbolic and political purposes in order to le gitimate preestablished goals and strategies. Nonetheless, amid this diversity and variety, troubling general questions persistently arise. (shrink)

Thirty years after the publication of Marr's seminal book Vision the papers in this topic consider the contemporary status of his influential conception of three distinct levels of analysis for information-processing systems, and in particular the role of the algorithmic and representational level with its cognitive-level concepts.

This book builds on existing work in genre analysis and move analysis in English for Specific Purposes and applies this new framework to academic philosophical discourse, offering new insights into how ESP traditions can elucidate shifts in language conventions across disciplinary contexts. The volume begins by surveying the state-of-the-art in English for Specific Purposes and genre theory, as well as other genre theory paradigms before turning the focus on move analysis. Lucas and Lucas seek to maximize the (...) potential of move analysis to precisely operationalize functional units of discourse by implementing a cognitive theory of genre grounded in frame semantics. Using the case of academic research articles in philosophy, the authors demonstrate how this framework can reveal distinctive dimensions unique to philosophical discourse and in turn, how such an approach might be applied more broadly to examine nuances in language across disciplines and inform ESP research in the future. This book will appeal to students and researchers in English for Specific Purposes, discourse analysis, academic writing, applied linguistics, and rhetoric and composition. (shrink)

The book questions two key dichotomies: that of the apparent and real, and that of the internal and external. This leads to revised notions of the structure of experience and the object of knowledge. Our world is experienced as possibilities of action, and to know is to know what to do. A further consequence is that the mind is best considered as a property of organisms' interactions with their environment. The unit of analysis is the loop of action and (...) perception, and the central concept is the notion of habit of action, which provides the embodied basis of cognition as the anticipation of action. This holds for non-linguistic tacit meanings as well as for linguistic meanings. Habit of action is a teleological notion and thus opens a possibility for defining intentionality and normativity in terms of the soft naturalism adopted in the book. The mind is embodied, and this embodiment determines our physical perspective on the world. Our sensory organs and other instruments give us instrumental access to the world, and this access is epistemic in character. The distinction between the physical and conceptual viewpoint allows us to define truth as the correspondence with operational fit. This embodied epistemic truth is however not a sign of antirealism, as the instrumentally accessed theoretical objects are precisely those objects that experimental science deals with.. (shrink)

Against the backdrop of cultural and political ideals, this article highlights both the significance of mental health nursing in meeting population needs and the regulatory barriers that may be impeding its ability to adequately do so. Specifically, we consider how ambiguous notions of ‘proficiency’ in nurse education—prescribed by the regulator—impact the development of future mental health nurses and their mental health nursing identity. A key tension in mental health practice is the ethical‐legal challenges posed by sanctioned powers to restrict patients' (...) freedom at the same time as the desire (and obligation) to promote patients' self‐determined recovery. The genericism of the UK's Future Nurse Standards do little to prepare mental health nurses to navigate the tensions that ensue. This has consequences for nurses and patients alike, as both risk experiencing the distress and dissonance that attends giving or receiving poor care. We argue that more needs to be done to enable mental health nurses to define and articulate the nuances of the profession as part of becoming critical, thoughtful and confident practitioners. Educators can contribute to this mission by aligning curriculum, pedagogy and assessment to create meaningful opportunities for mental health nursing students to engage with the complexities of mental health nursing practice. Without this, the credibility of the profession will continue to be questioned; its future uncertain. (shrink)

The kind of collective improvisation attained by the “free jazz” at the beginning of the sixties sets a challenge to analytic theories of collective intentionality, that emphasize the role played by future-directed plans in the interlocking and interdependent intentions of the individual participants, because in the free jazz case the performers’ interdependence or [interplay] stems from an intuitive understanding between musicians. Otherwise said: what happens musically is not planned in advance, but arises from spontaneous interactions in the group. By looking (...) at the way jazz improvisers take up the challenge of making music together without a pre-conceived notion as to what kind of effect they will achieve and without a pre-set code of agreements, my aim has been to clarify what kind of strategies — other than advanced action plans and joint commitments — are used by improvising musicians to integrate their improvisations into a unified shared activity. In developing this proposal I initially drawn pre-theoretically on one paradigmatic study case — Ornette Coleman’s double quartet Free Jazz, A collective Improvisation and brought it in conversation with Husserl’s phenomenology of time. In a final move, I brought this phenomenological frame into dialogue with some recent readings of the predictive coding model. All in all, what we learned from the Free Jazz case is that the interdependence and interlocking of attitudes among individual participants characteristic of shared intention is not determined by a future-directed plan and the rational pressure to be responsive to and coordinate with others, it typically engages. Rather, in the free jazz case, the performers’ connection and interplay depend on the players’ readiness to feel each other out, by listening to each other playing, in a way that no doubt presupposes the Husserlian retention-protention scheme.

This study considers the role of different cognitive units in sound change: phonemes, contextual variants and words. We examine /u/-fronting and /j/-dropping in data from three generations of Derby English speakers. We analyze dynamic formant data and auditory judgments, using mixed effects regression methods, including generalized additive mixed models (GAMMs). /u/-fronting is reaching its end-point, showing complex conditioning by context and a frequency effect that weakens over time. /j/-dropping is declining, with low-frequency words showing more innovative variants with /j/ (...) than high-frequency words. The two processes interact: words with variable /j/-dropping (new) exhibit more fronting than words that never have /j/ (noodle) even when the /j/ is deleted. These results support models of change that rely on phonetically detailed representations for both word- and sound-level cognitive units. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Walking the Bodhisattva Path/Walking the Christ PathU.S. Conference of Catholic BishopsCatholics and Buddhists brought together by Dharma Realm Buddhist Association, the San Francisco Zen Center, and the United States Conference of Catholic Bishops (USCCB) met 20-23 March 2003 in the first of an anticipated series of four annual dialogues. Abbot Heng Lyu, the monks and nuns, and members of the Dharma Realm Buddhist Association hosted the dialogue at the (...) City of Ten Thousand Buddhas in Talmage, California. The community had transformed their Confucius Hall into a chapel, with a large, newly constructed wooden cross on a wall above an altar facing out from a raised platform, so the Catholic delegation would have a space for worship. A special poster announcing the theme of the conference, "Walking the Bodhisattva Path/Walking the Christ Path," showing a Buddhist dharma wheel at one foot of a bridge and a Celtic cross at the other foot, had been created by the hosting community.The daily schedule for the dialogue did not interfere with the monastic routine at the City of Ten Thousand Buddhas, which included early morning chanting (4:00-5:00 am), daily rituals in the Buddha Hall, and the single large meal for monastics before noon to which all participants were invited. Catholics and Buddhists meeting in the dialogue began each day with an optional forty-five minutes of quiet sitting together in the monastery meditation hall, each following their own form of meditation and prayer. There was a Eucharist on Friday and Saturday evenings for the Catholics and to which the Buddhists were invited, and additional meals of breakfast and supper throughout the meeting at the City's Jyun Kang Restaurant.Fourteen Buddhists and fourteen Catholics participated in the formal discussions. Each participant spoke on what it means to them to follow Christ or the way of the Bodhisattvas or enlightened beings. In addition to speaking, each participant distributed a short passage, usually from a traditional text, on this topic. Several passages from Master Dogen's Shobogenzo and the Gospel of John were among those shared by the group. Other passages shared were taken from the Avatamsaka Sutra and the Shurangama Sutra and from the other gospels and the writings of Zen master HakuinZenji, the Dalai Lama, Korean Zen Master I-sahn Hye-yeon, the teachings of Master [End Page 247] Hsuan Hua, Shantideva, Origen, St. Ignatius, St. Benedict, the author of The Cloud of Unknowing, St. John of the Cross, and Chiara Lubich. A minute of silence separated the fifteen-minute segments for each presentation. With so large a group, most of the time in the formal sessions involved listening to series of presentations; however, during discussion periods the participants asked several challenging questions of one another.Some participants noted the tension they felt between belonging to a particular religious group and the need to let go of any consequential narrowness. The goal of the discussion was to promote understanding of the differences and similarities between Christianity and Buddhism. At one point, the participants noted several concerns about mutual enrichment: whether Buddhist methods can be separated from Buddhism and Christian methods from Christianity, and what specific aspects of Christian practice truly enrich Buddhists and which Buddhist practices likewise enrich Christians. Several times participants discussed their understanding of terms such as transformation, grace, the incarnation and the passion of Jesus, discernment of spirits, prayer, Buddha-nature, and related terms. There was consensus that Buddhists and Catholics can practically help one another regarding mental cultivation and religious precepts. They expressed this consensus in their choice of the topic forthe next dialogue, "Transformation of Hearts and Minds: Chan/Zen-Catholic Approaches to Precepts."The group agreed to reconvene in 2004 to respond to six presentations, three from each side, on different aspects of this topic.Chairing the sessions were Rev. Heng Sure for the Dharma Realm Buddhist Association, Rev. Taigen Dan Leighton for the San Francisco Zen Center, and Bishop John Webster for the United States Conference of Catholic Bishops. Their three organizations are the sponsors of the Northern California Chan/Zen-Catholic Dialogue. Chan and Zen are respectively the Chinese and Japanese terms for the meditation school... (shrink)

Are all three of Marr's levels needed? Should they be kept distinct? We argue for the distinct contributions and methodologies of each level of analysis. It is important to maintain them because they provide three different perspectives required to understand mechanisms, especially information-processing mechanisms. The computational perspective provides an understanding of how a mechanism functions in broader environments that determines the computations it needs to perform. The representation and algorithmic perspective offers an understanding of how information about the environment (...) is encoded within the mechanism and what are the patterns of organization that enable the parts of the mechanism to produce the phenomenon. The implementation perspective yields an understanding of the neural details of the mechanism and how they constrain function and algorithms. Once we adequately characterize the distinct role of each level of analysis, it is fairly straightforward to see how they relate. (shrink)

Over the past 50 years decision making research in team invasion sport has been dominated by three research perspectives,information processing,ecological dynamics, andnaturalistic decision making. Recently, attempts have been made to integrate perspectives, as conceptual similarities demonstrate the decision making process as an interaction between a players perception of game information and the individual and collective capability to act on it. Despite this, no common ground has been found regarding what connects perception and action during performance. The differences between perspectives rest (...) on the role of stored mental representations, that may, or may not facilitate the retrieval of appropriate responses in time pressured competitive environments. Additionally, in team invasion sports like rugby union, the time available to players to perceive, access memory and act, alters rapidly between specific game situations. Therefore, the aim of this study was to examine theoretical differences and the mechanisms that underpin them, through the vehicle of rugby union. Sixteen semi-elite rugby union players took part in two post-game procedures to explore the following research objectives; (i) to consider how game situations influence players perception of information; (ii) to consider how game situations influence the application of cognitive mechanisms whilst making decisions; and (iii) to identify the influence of tactics and/or strategy on player decision making. Deductive content analysis and elementary units of meaning derived from self-confrontation elicitation interviews indicate that specific game situations such as; the lineout, scrum or open phases of play or the tackle situation in attack or defence all provide players with varying complexity of perceptual information, formed through game information and time available to make decisions. As time increased, players were more likely to engage with task-specific declarative knowledge-of the game, stored as mental representations. As time diminished, players tended to diagnose and update their knowledge-in the game in a rapid fashion. Occasionally, when players described having no time, they verbalised reacting on instinct through a direct connection between perception and action. From these findings, clear practical implications and directions for future research and dissemination are discussed. (shrink)

The COVID-19 pandemic has had a significant negative effect on university students’ mental health worldwide. The pandemic has resulted in individuals experiencing increased levels of anxiety and stress as well as intensified concerns about the future due to a rise in uncertainty. To eliminate the anxiety and stress caused by uncertainty, individuals who have high cognitive closure needs are strongly motivated to achieve certainty and seek answers, even if the decisions they make in the process are inappropriate or even irrational. (...) This study attempts to analyze the influence of anxiety and stress on university students’ academic involution behavior during the COVID-19 pandemic through the mediating effect of the need for cognitive closure. Analyzing the survey data collected from 402 university students from 3 different universities through the mediating effect model and path analysis with latent variable, our results indicate that: The COVID-19 pandemic has significantly increased the levels of anxiety and stress experienced by university students. The path coefficient of the perceived risk of contracting COVID-19 to perceived emotions was 0.352, anxiety and stress significantly and positively affect academic involution behavior. For each unit of increase in the scores of anxiety and stress, the scores of academic involution behavior increased by 0.408 and 0.398 units, respectively, and The need for cognitive closure had a complete and partial mediating effect on the relationship between the perceived risk of contracting COVID-19 and academic involution behavior, as well as anxiety and academic involution behavior, respectively. The results of PA-LV showed that the mediating effect values were 0.106 and 0.044, respectively. The impact of the COVID-19 pandemic has not yet come to an end and so clarifying the relationship between anxiety and academic involution behavior will assist university students to optimize the relationship in their own subjective situations, to establish good learning habits, and reduce psychological distress.

Previous research has shown that Need for Cognition, the individual tendency to engage in and enjoy cognitive endeavors, contributes to academic performance. Most studies on NFC and related constructs have thereby focused on grades to capture tertiary academic success. This study aimed at a more comprehensive approach on NFC’s meaning to success in university. We examined not only performance but also rather affective indicators of success. The current sample consisted of 396 students of different subjects with a mean age (...) of 24 years. All participants took part in an online survey that assessed NFC together with school performance and further personality variables via self-report. Success in university was comprehensively operationalized including performance, satisfaction with one’s studies, and thoughts about quitting/changing one’s major as indicators. The value of NFC in predicting tertiary academic success was examined with correlation analyses and path analysis. NFC significantly correlated with all success variables with the highest correlation for study satisfaction. Path analysis confirmed the importance of NFC for study satisfaction showing that NFC had a significant direct effect on study satisfaction and via this variable also a significant indirect effect on termination thoughts. This study clearly indicates that NFC broadly contributes to the mastery of academic requirements and that it is worthwhile to intensify research on NFC in the context of tertiary education.

I consider how we might begin to redress a cognitive model for thought experimental and other imagery-based scientific reasoning from an embodied cognition viewpoint. The paper gravitates on clarifying tour issues: (i) the danger of understanding the genuine novelty of thought-experimental reasoning and other imagery-based reasoning as a product of ‘quasi-perceiving’ new phenomenology with the ‘mind’s eye’ (as asserted by quasi-pictorialist theories of imagery); (ii) the erroneous choice of units of analysis that assume equivalence of external reports (...) of visual imagery with those internal structures that govern imagery-based reasoning, which are, as I will argue, largely linked to motor processes; (iii) the establishment of thought experimentation as imagery-based reasoning by providing evidence for the psychological necessity of imagistic simulation in thought experiments; (iv) a cognitive model for how learning via thought experimentation and other imagery-based reasoning takes place. The study was underpinned by constructivist assumptions. Case methodology was adopted, the case being a pair of final year A-level physics students. Data was collected through non-participant observation over two sessions of collaborative problem-solving. The tasks drew upon Newtonian mechanics. (shrink)

Background: There is increasing evidence to support the efficacy of transcranial direct current stimulation applications in cognitive augmentation and rehabilitation. Neuromodulation achieved with tDCS may further regulate regional cerebral perfusion affiliated through the neurovascular unit; however, components of cerebral perfusion decrease across aging. A novel neuroimaging approach, functional near-infrared spectroscopy, can aid in quantifying these regional perfusional changes. To date, the interaction of the effects of tDCS on cognitive performance across the lifespan and obtained fNIRS hemodynamic responses remain unknown.Objective: This (...) review aims to examine the effects of tDCS on cognitive performance and fNIRS hemodynamic responses within the context of cognitive aging.Methods: Six databases were searched for studies. Quality appraisal and data extraction were conducted by two independent reviewers. Meta-analysis was carried out to determine overall and subgroup effect sizes.Results: Eight studies met inclusion criteria. The overall effect size demonstrates that tDCS can alter cognitive performance and fNIRS signals, with aging being a potential intermediary in tDCS efficacy.Conclusion: From the studies included, the effects of tDCS on cognitive performance and fNIRS metrics are most prominent in young healthy adults and appear to become less robust with increasing age. Given the small number of studies included in this review further investigation is recommended. (shrink)

The need for cognitive closure is a construct postulated by Kruglanski that explains the motivational aspects which influence decision-making and its impact on the social environment. Initially, it was assessed through a unidimensional scale, later criticized for its poor satisfactory reliability and validity. Regarding these criticisms, Pierro and Kruglanski developed a new 14-item scale to measure two dimensions, which were not previously evaluated: urgency tendency and permanence tendency. Although the Revised Test of Need for Cognitive Closure is more economical in (...) terms of assessment time, it would be optimal to develop a reduced test that can assess faster while maintaining validity and reliability. The present research aims to reduce the Revised Test of Need for Cognitive Closure scale to the Argentinian context. To this end, we worked on a non-experimental design, assessing this scale within a sample of 690 Argentinian university students, and proceeded to perform reliability, as well as confirmatory factor analysis, convergent validity, and factorial invariance analysis. The results indicate a bi-factorial structure of a Need for Cognitive Closure instrument with eight items and two dimensions: urgency tendency and permanence tendency, suggesting good reliability in both of them. In addition, well convergent validity was checked with other validated instruments, and finally, the factor loadings were shown to be invariant. In conclusion, it was demonstrated the reliability and validity of reducing the Revised Test of Need for Cognitive Closure in our social environment. (shrink)

Even though it has been argued that scientific cognition is distributed, there is no consensus on the exact nature of distributed cognition. This paper aims to characterize distributed cognition as appropriate for philosophical studies of science. I first classify competing characterizations into three types: the property approach, the task approach, and the system approach. It turns out that the property approach and the task approach are subject to criticism. I then argue that the most preferable way to (...) understand distributed cognition in science is provided by the system approach that takes a distributed-cognitive system as the unit of analysis. I clarify this position by considering possible objections and replies. (shrink)

This paper examines five groups of women that were instrumental in the emergence of the category of “feeblemindedness” in the United States. It analyzes the dynamics of oppression and power relations in the following five groups of women: “feebleminded” women, institutional caregivers, mothers, researchers, and reformists. Ultimately, I argue that a feminist analysis of the history of mental retardation is necessary to serve as a guide for future feminist work on cognitive disability.

Marr's levels of analysis—computational, algorithmic, and implementation—have served cognitive science well over the last 30 years. But the recent increase in the popularity of the computational level raises a new challenge: How do we begin to relate models at different levels of analysis? We propose that it is possible to define levels of analysis that lie between the computational and the algorithmic, providing a way to build a bridge between computational- and algorithmic-level models. The key idea is (...) to push the notion of rationality, often used in defining computational-level models, deeper toward the algorithmic level. We offer a simple recipe for reverse-engineering the mind's cognitive strategies by deriving optimal algorithms for a series of increasingly more realistic abstract computational architectures, which we call “resource-rational analysis.”.

In this work, we study and analyze the aggregate death counts of COVID-19 reported by the United States Centers for Disease Control and Prevention (CDC) for the fifty states in the United States. To do this, we derive a stochastic model describing the cumulative number of deaths reported daily by CDC from the first time Covid-19 death is recorded to June 20, 2021 in the United States, and provide a forecast for the death cases. The stochastic model derived in this (...) work performs better than existing deterministic logistic models because it is able to capture irregularities in the sample path of the aggregate death counts. The probability distribution of the aggregate death counts is derived, analyzed, and used to estimate the count’s per capita initial growth rate, carrying capacity, and the expected value for each given day as at the time this research is conducted. Using this distribution, we estimate the expected first passage time when the aggregate death count is slowing down. Our result shows that the expected aggregate death count is slowing down in all states as at the time this analysis is conducted (June 2021). A formula for predicting the end of Covid-19 deaths is derived. The daily expected death count for each states is plotted as a function of time. The probability density function for the current day, together with the forecast and its confidence interval for the next four days, and the root mean square error for our simulation results are estimated.

The current COVID-19 pandemic has affected the entire globe, including the world of high-performance sports. Accordingly, it has been widely assumed that the thereby caused postponement of the Tokyo 2020 Olympic Games could have negative psychological impacts for aspirants, since they were halted abruptly in the pursuit of their Olympic endeavors and their daily lives drastically altered. Considering the sudden nature of the pandemic, few researchers, if any, have yet scrutinized the individual experience of Olympic aspirants. This qualitative study examines (...) the subjective perceptions of the Tokyo 2020 Olympic Games postponement among Austrian Olympic athletes and coaches. To this end, 21 Austrian athletes (13 male, 8 female; mean age = 26.67 ± 4.93 years) and six male coaches were recruited through a criterion-based purposive sampling strategy. Five athletes had already qualified for the Olympic Games in Tokyo 2020 and 15 athletes were still in an ongoing qualification process. Data was collected by means of short written statements, elicited via open-format questions on an anonymous online survey platform. In order to infer meaning from the text, a qualitative content analysis with an interpretative focus was conducted inductively, which allowed for deriving alternative explanations of findings. The results support the notion that the Olympic postponement was experienced in myriad ways by affected participants. Three general themes comprised of several meaning units of different levels of abstraction were created from the text data. Many respondents experienced an immediate emotional reaction to the postponement characterized by confusion, disappointment and/or relief. Participants associated multiple consequences with the postponement, such as the prolongation of physical and psychological pressure, a lack of motivation, concerns about future performance, living and their occupational career, but also the opportunity for performance improvement and recovery. Respondents displayed various coping strategies, such as distancing themselves from sports, cognitive reframing, appealing for acceptance, and planning behavior. This study gleans first insights into the idiosyncratic experience of the Olympic Games 2020 postponement among Austrian aspirants. The findings could serve to assist sport psychologists in their applied practice by informing them about athletes’ and coaches’ needs in their Olympic preparation during the ongoing pandemic.

This paper examines five groups of women that were instrumental in the emergence of the category of "feeblemindedness" in the United States. It analyzes the dynamics of oppression and power relations in the following five groups of women: "feeble-minded" women, institutional caregivers, mothers, researchers, and reformists. Ultimately, I argue that a feminist analysis of the history of mental retardation is necessary to serve as a guide for future feminist work on cognitive disability.

Background Supporting physicians in Intensive Care Units s as they face dying patients at unprecedented levels due to the COVID-19 pandemic is critical. Amidst a dearth of such data and guided by evidence that nurses in ICUs experience personal, professional and existential issues in similar conditions, a systematic scoping review is proposed to evaluate prevailing accounts of physicians facing dying patients in ICUs through the lens of Personhood. Such data would enhance understanding and guide the provision of better support (...) for ICU physicians. Methods An SSR adopts the Systematic Evidenced Based Approach to map prevailing accounts of caring for dying patients in ICUs. To enhance the transparency and reproducibility of this process, concurrent and independent use of tabulated summaries, thematic analysis and directed content analysis is adopted. Results Eight thousand three hundred fifty-eight abstracts were reviewed from four databases, 474 full-text articles were evaluated, 58 articles were included, and the Split Approach revealed six categories/themes centered around the Innate, Individual, Relational and Societal Rings of Personhood, conflicts in providing end of life care and coping mechanisms employed. Conclusion This SSR suggests that caring for dying patients in ICU impacts how physicians view their personhood. To resolve conflicts within individual concepts of personhood, physicians use prioritization, reframing and rely on accessible, personalized support from colleagues to steer coping strategies. An adapted form of the Ring Theory of Personhood is proposed to direct timely personalized, appropriate and holistic support. (shrink)

Numerous empirical studies have been conducted to examine first-generation college students, those individuals whose parents have not attended college. Their personality characteristics, cognitive development, academic preparation, and first-year performance have all been topics of research; yet there appears to be little in the literature exploring the motivation of these individuals to seek higher education. There are even fewer studies targeting academic motivation in Hispanic students. The purpose of this study is to conduct a phenomenological examination of the desire to attend (...) college among first generation Hispanic students participating in an academic support program. One-hour taped interviews were conducted with three volunteer participants enrolled in the Student Support Services program at Sul Ross State University. Meaning units and constituents were extracted, and general structures were developed using the Descriptive Phenomenological Method . The phenomenological analysis resulted in two structures that address the effectiveness of academic outreach programming and identify the roles of self-efficacy, successful experiences in high school, a desire for improved socioeconomic status, a need to contribute to the well-being of others, a break with tradition, and the influence of respected role models in facilitating a desire for higher education in first-generation Hispanic college students.

This article proposes two conditions to assess whether an entity at a level of description is a unit of selection qua interactor. These two conditions make it possible to (1) distinguish biologically relevant entities from arbitrary ones and (2) distinguish units that can _potentially_ enter a selection process from those that have already done so. I show that the classical approaches used in the literature on units and levels of selection do not fare well with respect to either (...) or both of these desiderata. (shrink)

ObjectiveThe objective of this paper is to evaluate the cognitive benefit of exercise after stroke, so as to provide more accurate and reliable guidance for targeted exercise intervention. Methods. Randomized controlled trials of the relationship between exercise and cognition after stroke were identified in Cochrane Library and PubMed. Methodological quality was assessed using the Cochrane tool of bias. SMD and 95% confidence intervals were calculated, and Chi-squared test was adopted to estimate the heterogeneity. Results. Twenty-three studies met inclusion criteria, (...) including 1528 participants. Heterogeneity was from low to high such as attention, executive function, cognition, and working memory. The overall effect on cognition was small but significant and there is a difference between cognitive domains in attention, executive function, and working memory. Exercise training was less effective before the 18th month after stroke. Higher benefits on cognition were found after combined therapy compared with other exercise programs, and the older the stroke survivors, the less the cognitive benefit of exercise. Conclusion. Small-to-moderate effect of exercise on cognitive benefit after stroke was found, and the effect was moderated by treatment protocols and sample characteristics. (shrink)

This is a contribution to construction of a research roadmap for future cognitive systems, including intelligent robots, in the context of the euCognition network, and UKCRC Grand Challenge 5: Architecture of Brain and Mind. -/- A meeting on the euCognition roadmap project was held at Munich Airport on 11th Jan 2007. This document was in part a response to discussions at that meeting. An explanation of why specifying requirements is a hard problem, and why it needs to be done, along (...) with some suggestions for making progress, can be found in this presentation: http://www.cs.bham.ac.uk/research/projects/cosy/papers/#pr0701 "What's a Research Roadmap For? Why do we need one? How can we produce one?" Working on that presentation made me realise that certain deceptively familiar words and phrases frequently used in this context (e.g. "robust". "flexible", "autonomous") appear not to need explanation because everyone understands them, whereas in fact they have obscure semantics that needs to be elucidated. Only then can we understand what the implications are for research targets. In particular, they need explanation and analysis if they are to be used to specify requirements and research goals, especially for publicly funded projects. -/- First draft analyses are presented here. In the long term I would like to expand and clarify those analyses, and to provide many different examples to illustrate the points made. This will probably have to be a collaborative research activity. (shrink)

The paper adopts an inter-theoretical socio-cultural and -material perspective on the relationship between human + machine learning to propose a new way to investigate the human + machine assistive assemblages emerging in professional work (e.g. medicine, architecture, design and engineering). Its starting point is Hutchins’s (1995a) concept of ‘distributed cognition’ and his argument that his concept of ‘cultural ecosystems’ constitutes a unit of analysis to investigate collective human + machine working and learning (Hutchins, Philos Psychol 27:39–49, 2013). It (...) argues that: (i) the former offers a way to reveal the cultural constitution of and enactment of human + machine cognition and, in the process, the limitations of the computational and connectionist assumptions about learning that underpin, respectively, good old-fashioned AI and deep learning; and (2) the latter offers a way to identify, when amplified with insights from Socio-Materialism and Cultural-Historical Activity Theory, how ML is further rearranging and reorganising the distributed basis of cognition in assistive assemblages. The paper concludes by outlining a set of conjectures researchers that could use to guide their investigations into the ongoing design and deployment of HL + ML assemblages and challenges associated with the interaction between HL + ML.

Constitutional and judicial law-making is increasingly beginning to find its reflection not only in the Anglo-Saxon, but also in the Romano-Germanic legal family. However, the prerequisites for the use of this legal instrument are different, which determines the relevance of conducting a comparative analysis regarding the provision of such a mechanism in the USA and Kazakhstan. The purpose of the research is to identify common and distinctive features in the process of implementation of constitutional and judicial law-making in countries (...) belonging to different legal systems. The article uses the methods of analysis, synthesis, comparison, deduction and generalization. As a result, the specificity of ensuring the mechanism of constitutional law-making in the USA was expressed, taking into account various forms of law-making activity. It has been established that the development of constitutional provisions in the United States takes place with the help of the constitutional doctrines of the Supreme Court of the United States, which provide for the introduction of amendments to constitutional provisions without a formal procedure. As a result of the study of the experience of Kazakhstan, it was established that special priority was given to the role of precedent, in particular, the decision of the Supreme Court of the Republic of Kazakhstan. This is explained by the integrative nature of the Romano-Germanic legal system, which allows effective development of national legislation as a whole and its provisions. The obtained results can be used during the professional training of judges in the Republic of Kazakhstan. (shrink)

This paper addresses the field of economic measurements of the value of assets, carried out by the methods of independent expert evaluation. The mathematical principles of application, within a comparative methodical approach, of additive and multiplicative models for correcting the cost of single indicator of compared objects have been considered. The differences of mathematical basis of the compared models were analyzed. It has been shown that the ambiguity in the methodology of correction procedure requires studying the advantages and disadvantages of (...) known models, as well as the justification and elaboration of recommendations for their application. Possible forms of correction representation using several alternative units of measurement have been defined; formulas for their interconnection have been built. Analytic expressions have been derived that mathematically describe the algorithms for performing the evaluation correction procedure using various forms of correction representation. The influence of the correction execution model on the characteristics of uncertainty in the independent evaluation result has been analyzed. The scope of two possible types of correction introduction models has been determined. A specific numerical example was used to demonstrate the methodological advantages of using a multiplicative model when summarizing percentage corrections. The independence of the correction result on the sequence of correction introduction has been confirmed. It is proposed to use the selected measure of partial corrections as a criterion for the adequacy of the correction introduction model. It is proved that the result of the independent expert evaluation depends on the chosen model and does not depend on the sequence of correction introduction. The reported study results are important in terms of theory and practice since they make it possible to improve the accuracy and reliability of the result of independent expert evaluation. (shrink)

An axiomatization of the theory is presented based on an explication of the 1957 text. Twenty-five theorems are deduced from the seven postulates. An abstract test space for the theory is formulated and the operations for its practical testing discussed. Traditional experimentation with the theory seems generally concerned with few of its propositions and incapable of testing it.

A correct analysis of hierarchical selection processes must specify 1) the objects that succeed differentially as units, and 2) the properties that provide the causal bases for differential success. Here I illustrate how failing to recognize the units/bases distinction creates a contradiction in Elliott Sober's recent account of selection. A revised criterion for units of selection is developed and applied to examples at several biological levels. Criteria for bases of selection are discussed in terms of the (...) degree of context-dependence and directness of a property's effect on the success of units. The significance of previous work by Sober, Wimsatt and Brandon is thereby clarified. (shrink)

The study of social norms sprawls across all of the social sciences but the the concept lacks a unified conception and formal theory. We synthesize an account that can be applied generally, at the social scale of analysis, and can be applied to empirical evidence generated in field and lab experiments. More specifically, we provide new analysis on representing norms for application in empirical political science, and in parts of economics that do not follow the recent trend among (...) some behavioral economists to build models of the cognitive and motivational states of individuals taken “one at a time”. Foundational sources for our project are Bicchieri (2006, 2017), Kuran (1995), and Stirling (2012, 2016). From Bicchieri take that a norm exists in a social structure when a significant networked subset of individuals share descriptive and injunctive expectations that it regulates their interactions. From Kuran we take the insight that prevailing norms may come to be widely disliked by participants in networks but survive because norm suppress public displays of disenchantment. From Stirling we apply conditional game theory (CGT) to provide the technical resources for building our model of a norm-regulated social interaction. The example we use is a multi-player Investment/Trust Game. (shrink)

The negation constitutes one of the main troubles for attempts to naturalise the semantics of the logical vocabulary, as shown by the problems related to the interpretation of disjunction in the treatment of error (Fodor) or to the definition of contraries in the analysis of reidentification abilities (Millikan). There seems to be no way out between “no (naturalized) negation, no grip of logic on the world” and “no (truth-functional) negation, no logic”. Unexpected help may come from the cognitive phenomenology (...) of negation. For three reasons: • Firstly, because it allows a distinction to be made between semantic analysis, identification of the possession conditions and psychology of the acquisition of the notion of negation, a distinction whose absence produces many misunderstandings between those who support a naturalization of semantics and those who oppose it. • Then because it places negation at the level of the contrast between beliefs, a terrain that is hostile to some naturalizers. • Finally, because it makes it possible to define a peculiar type of liberalised naturalization of semantics and, consequently, to present a hypothesis for the naturalization of cognitive phenomenology.
