This study investigated the effects of music therapy and pictorial illustration on the attention span of children with mild intellectual difficulties. A pre-test, post-test and control group quasi-experimental research design was used with a sample of children diagnosed with mild intellectual disability from three special schools in Ibadan, Nigeria. Fifty children were randomly selected and assigned to one of three groups: music therapy, pictorial illustration, or control. Twenty-four sessions of music therapy and pictorial illustration classes were held with (...) the experimental group only. The Moss Attention Rating Scale was used before and after the intervention to collect data on participants’ attention span. Analysis of Covariance indicated that there was a significant statistical difference between pre-test and post-test results of the two groups. The estimated marginal means of post-attention span by treatment indicated that pictorial illustration had the highest post-attention span score, followed by music therapy, while post-attention span score for the control group was the least. Based on the findings, it is recommended that teachers, caregivers, and parents of children with mild intellectual disability adopt pictorial illustration and music therapy as teaching strategies to enhance their attention span.

The visual attention (VA) span is defined as the amount of distinct visual elements which can be processed in parallel in a multi-element array. Both recent empirical data and theoretical accounts suggest that a VA span deficit might contribute to developmental dyslexia, independently of a phonological disorder. In this study, this hypothesis was assessed in two large samples of French and British dyslexic children whose performance was compared to that of chronological-age matched control children. Results of the (...) French study show that the VA span capacities account for a substantial amount of unique variance in reading, as do phonological skills. The British study replicates this finding and further reveals that the contribution of the VA span to reading performance remains even after controlling IQ, verbal fluency, vocabulary and single letter identification skills, in addition to phoneme awareness. In both studies, most dyslexic children exhibit a selective phonological or VA span disorder. Overall, these findings support a multi-factorial view of developmental dyslexia. In many cases, developmental reading disorders do not seem to be due to phonological disorders. We propose that a VA span deficit is a likely alternative underlying cognitive deficit in dyslexia.

It has been suggested that there is a close relationship between visual attention span (VAS) and fluent reading. This relation may be modulated by participants’ age, and exhibits various patterns in different reading modes (i.e. oral v.s. silent reading) and different reading levels (e.g. sentence v.s. character/word levels). Moreover, the modulation effects from the above factors might be more remarkable in the framework of languages with a deep orthography. Therefore, the present study investigated the developmental pattern of the (...) relationship between VAS skills and reading fluency in Chinese, a language with particularly deep orthography, by recruiting 292 participants from primary schools, middle schools and universities. Two tests were utilized to assess fluent reading skills at the single-character and sentence levels with oral and silent reading modes. A visual 1-back task was adopted to reflect VAS capacity with non-verbal stimuli and no verbal response. Results showed that the VAS capacity of low-grade primary school students could significantly account for the variance in single-character reading fluency in the oral mode and that it was a significant predictor of sentence reading fluency in the oral mode among high-grade primary school students. VAS abilities of middle school students allowed a unique and stable prediction of their silent sentence reading. With increasing reading ability, VAS skills of adults showed significant and similar predictive power for estimating the variations in fluent sentence reading in both silent and oral modes. These results revealed developmental changes in the contribution of VAS to fluent reading in Chinese, and provided evidence unveiling whether the underlying mechanisms of oral and silent reading were shared or different.

The goal of the current study is to investigate the effects of the distractive textual information on the activation of predictive inference online, and how the readers with high or low working memory capacity differ in their online activation and text memory. To test the two hypothesis of attentional competition and semantic integration, we conducted three experiments to investigate whether a local prediction and a global prediction, both of which could be derived from the description of a critical event, are (...) generated in the mind of the reader, and how this generation process is influenced by contextual and cognitive factors of the reader. The results of Experiment 1 and 2 suggest that the elaboration of the global aspects in the narrative reduces the local prediction, but makes the global prediction more salient to occur. The evidence from Experiment 3 confirms the hypothesis that even automatic processes are constrained by distant contextual factors, in combination with differences in working memory, and examines how referentially local and global predictions are intertwined in text comprehension. Overall, these data support the immediate integration hypothesis across sentence boundaries at different representation levels, as well as interaction assumptions of different processing levels within referentially local and referentially global processing contexts.

Much of cognitive psychology focuses on effects measured in tens of milliseconds while significant educational outcomes take tens of hours to achieve. The task of bridging this gap is analyzed in terms of Newell's (1990) bands of cognition—the Biological, Cognitive, Rational, and Social Bands. The 10 millisecond effects reside in his Biological Band while the significant learning outcomes reside in his Social Band. The paper assesses three theses: The Decomposition Thesis claims that learning occurring at the Social Band can be (...) reduced to learning occurring at lower bands. The Relevance Thesis claims that instructional outcomes at the Social Band can be improved by paying attention to cognition at the lower bands. The Modeling Thesis claims that cognitive modeling provides a basis for bridging between events on the small scale and desired outcomes on the large scale. The unit-task level, at the boundary of the Cognitive and Rational Bands, is useful for assessing these theses. There is good evidence for all three theses in efforts that bridge from the unit-task level to educational applications. While there is evidence for the Decomposition Thesis all the way down to the 10 millisecond level, more work needs to be done to establish the Relevance Thesis and particularly the Modeling Thesis at the lower levels.

An absolute decline in US life expectancy in low education whites has alarmed policy makers and attracted media attention. Depending on which studies are correct, low education white women have lost between 3 and 5 years of lifespan; men, between 6 months and 3 years. Although absolute declines in life expectancy are relatively rare, some commentators see the public alarm as reflecting a racist concern for white lives over black ones. How ought we ethically to evaluate this lifespan contraction (...) in low education whites? Should we care, or is it racist to care? Does it constitute an injustice or reflect justice being done? I argue that the lifespan contraction in low education whites violates key normative criteria used to make determinations of health justice, and that these judgments do not vitiate concerns about racism. I conclude with reflections on US population health policy and building an inclusive health equity movement. (shrink)

By combining a flanker task and a cuing task into a single paradigm, the authors assessed the effects of orienting and alerting on conflict resolution and explored how normal aging and Alzheimer’s disease (AD) modulate these attentional functions. Orienting failed to enhance conflict resolution; alerting was most beneficial for trials without conflict, as if acting on response criterion rather than on information processing. Alerting cues were most effective in the older groups— healthy aging and AD. Conflict resolution was impaired only (...) in AD. Orienting remained unchanged across groups. These findings provide evidence of different life span developmental and clinical trajectories for each attentional network. (shrink)

The nature of attention is one of the oldest and most central problems in psychology. A huge amount of research has been produced on this subject in the last half century, especially on attention in the visual modality, but a general explanation has remained elusive. Many still view attention research as a field that is fundamentally fragmented. This book takes a different perspective and presents a unified theory of visual attention: the TVA model. The TVA model (...) explains the many aspects of visual attention by just two mechanisms for selection of information: filtering and pigeonholing. These mechanisms are described in a set of simple equations, which allow TVA to mathematically model a large number of classical results in the attention literature. The theory explains psychological and neuroscientific findings by the same equations; TVA is a complete theory of visual attention, linking mind and brain. Aimed at advanced students and professional researchers, Principles of Visual Attention contains a detailed review of the most important research done on attention in vision, spanning cognitive psychology, brain imaging, patient studies, and recordings from single cells in the visual cortex. The book explains the TVA model and shows how it accounts for attentional effects observed across all the research areas described. Principles of Visual Attention offers a uniquely integrated view on a central topic in cognitive neuroscience. (shrink)

All persons, while different from one another, have the same value: this is the author's relatively uncontroversial starting point. Her end point is not uncontroversial: an ideal of justice as human flourishing, based on each person's unique set of capabilities. Because the book's focus is women's health care, gender justice, a necessary component of justice, is central to examination of the issues. Classical pragmatists and feminist standpoint theorists are enlisted in support of a strategy by which gender justice is promoted. (...) Two features of the book are unique: (1) the topics presented cover the entire life span of women, not just those related to reproduction; (2) a range views about moral status are applied not only to fetuses but also to individuals already born. Attention to these features is intended to facilitate ethical consistency or moral integrity and respect for those who hold different moral views. While delineating and defending the book's perspective, the first section provides an overview of bioethics, critiques prevalent approaches to bioethics and models of the physician-patient relationship, and sketches distinguishing aspects of women's health care that are prevalently neglected. Positions about moral status are also presented. The second section identifies topics that are indirectly as well as directly related to women's health, such as domestic violence and caregiving. Brief cases illustrate variables relevant to each topic. Empirical and theoretical considerations follow each set of cases; these are intended to precipitate more expansive and critical examination of the issues raised. The last section is devoted to an egalitarian ideal that may be pursued through an ethic of virtue or supererogation rather than obligation. By embracing this ideal, according to the author, moral agents support a more demanding level of morality than guidelines or laws require. (shrink)

Dissociative style is mostly studied as a risk factor for dissociative pathology, but it may also reflect a fundamental characteristic of healthy information processing. Due to the close link between attention and working memory and the previous finding of enhanced attentional abilities with a high dissociative style, a positive relationship was also expected between dissociative style and verbal working memory span. In a sample of 119 psychology students, it was found that the verbal span of the high-dissociative (...) group was about half a word larger than of the medium and low-dissociative groups. It is suggested that dissociative style may be one of only very few individual differences that is directly relevant to consciousness research. (shrink)

Theory of Mind (ToM) or mentalization is the ability to understand and foresee the behavior referring to one's own and others' mental states (Premack & Woodruff, 1978; Wimmer & Perner, 1983). This capacity, which is considered the most representative mechanism of social cognition, is a multifaceted set of competences liable to influence--and be influenced by--a manifold of psychosocial aspects. Studies on typical and atypical/clinical development during life showed that ToM is frequently delayed (e.g. in deafness) or impaired in many clinical (...) conditions (e.g. Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder, Schizophrenia, Borderline Personality Disorder, Parkinson's Disease, Alzheimer's Disease) and, on the other hand, may not be unequivocally a positive experience. It is therefore possible to consider the existence of multiple kinds of Theory of Mind. In fact, ToM may vary along a quantitative and a qualitative continuum. As for the quantitative dimension, the continuum is constituted by the fluctuation between high and low levels of ToM ability in different clinical conditions. Along this continuum, impairment can mean "not enough" ToM (for example in Autism Spectrum Disorder) as well as "too much" ToM (for example in Schizophrenia and Borderline Personality Disorder). The qualitative dimension--highly interrelated with the quantitative one--regards the shift between adaptive (e.g. prosocial, nice ToM) vs. unadaptive (e.g. antisocial, nasty ToM) mental states content. The issue is discussed in light of recent evidence from outstanding researchers working on typical and atypical/clinical populations along the life-span. Findings from the fields of psychology, neuropsychology and neuroscience enrich the research topic argumentation"--Page 2. (shrink)

Debates about the ethical and social implications of research that aims to extend human longevity by intervening in the ageing process have paid little attention to the attitudes of members of the general public. In the absence of empirical evidence, conflicting assumptions have been made about likely public attitudes towards life-extension. In light of recent calls for greater public involvement in such discussions, this target article presents findings from focus groups and individual interviews which investigated whether members of the (...) general public identify ethical issues surrounding life-extension, and if so, what these ethical issues are? In this study, while some participants were concerned primarily with the likely personal consequences of life-extension, for others the question of whether or not to pursue interventions to extend longevity, and how they should be implemented, clearly raised important ethical issues, many of which have been prominent in debates among bioethicists.

We are largely in agreement with the Findlay & Walker model. However, they appear to dismiss the role of covert spatial attention in tasks in which people are free to move their eyes. We argue that an account of the facts about the perceptual span in reading requires a window of attention not centered around the fovea. Moreover, a computational model of reading that we (Reichle et al. 1998) developed gives a good account of eye movement control (...) in reading and would be unable to do so without relying heavily on covert attention.

Since the pioneering work of [Aglioti, S., DeSouza, J. F., & Goodale, M. A. . Size-contrast illusions deceive the eye but not the hand. Current Biology, 5, 679–685] visual illusions have been used to provide evidence for the functional division of labour within the visual system—one system for conscious perception and the other system for unconscious guidance of action. However, these studies were criticised for attentional mismatch between action and perception conditions and for the fact that grip size is not (...) determined by the size of an object but also by surrounding obstacles. Stoettinger and Perner [Stoettinger, E., & Perner, J., . Dissociating size representations for action and for conscious judgment: Grasping visual illusions without apparent obstacles. Consciousness and Cognition, 15, 269–284] used the diagonal illusion controlling for the influence of surrounding features on grip size and bimanual grasping to rule out attentional mismatch. Unfortunately, the latter objective was not fully achieved. In the present study, attentional mismatch was avoided by using only the dominant hand for action and for indicating perceived size. Results support the division of labour: Grip aperture follows actual size independent of illusory effects, while finger-thumb span indications of perceived length are clearly influenced by the illusion.

During the COVID-19 lockdown, individuals were forced to remain at home, hence severely limiting the interaction within environmental stimuli, reducing the cognitive load placed on spatial competences. The effects of the behavioral restriction on cognition have been little examined. The present study is aimed at analyzing the effects of lockdown on executive function prominently involved in adapting behavior to new environmental demands. We analyze non-verbal fluency abilities, as indirectly providing a measure of cognitive flexibility to react to spatial changes. Sixteen (...) students, evaluated before the start of the lockdown in a battery of psychological tasks exploring different cognitive domains, have been reassessed during lockdown. The assessment included the modified Five-Point Test to analyze non-verbal fluency abilities. At T2, the students were also administered the Toronto Alexithymia Scale. The restriction of behaviors following a lockdown determines increased non-verbal fluency, evidenced by the significant increase of the number of new drawings. We found worsened verbal span, while phonemic verbal fluency remained unchanged. Interestingly, we observed a significant tendency to use the left part of each box in the m-FPT correlated with TAS-20 and with the subscales that assess difficulty in describing and identifying feelings. Although our data were collected from a small sample, they evidence that the restriction of behaviors determines a leftward bias, suggesting a greater activation of the right hemisphere, intrinsically connected with the processing of non-verbal information and with the need to manage an emotional situation.

The author analyses the design of her collaborative animation about inattention blindness, the phenomenon of not being able to see things that are actually there, and compares it to related scientific research.1 The term was coined by Arien Mack and Irvin Rock in 1992. Stealing Attention, co-created by the author and neuroscientist Michael E. Goldberg, Director of the Mahoney Center for Brain and Behavior at Columbia University, explored inattention blindness. Animated images of hands playing the con game Three-Card Monte (...) were superimposed over images of antiquities stolen from Iraq. The flashing cards, yellow circles and stated instructions distracted the viewer from seeing the images of stolen antiquities, which disappeared from depicted shelves one by one over the time span of approximately three minutes. The author considers five questions: What is perceived without attention What does attention select Under what circumstances can attention be shifted Is an observer trained in art less likely to be distracted Can attention be trained.

This research thesis explores the concept of attention as outlined and practised in the life of Simone Weil (1909-1943), a French woman variously described as a philosopher, mystic and activist yet someone who eludes categorisation or systematisation. It outlines the background to her life in a France between two world wars, and seeks to situate her within the context of the Christianity she claimed as her cultural backdrop. It explores the concept of attention as both a spiritual exercise (...) and a practice in the life of Weil, something that then evolved into a core principle of her thinking. The central question here is the age-old one, harking back to ancient philosophy, concerning the living of a good life, particularly within the context of a lifelong acquaintanceship with Weil‘s work. As this study examines Weil‘s ideas on reading, it also interrogates how she is read, particularly by poets today, with a view to assessing her influence. Weil was a writer who loved poetry and wrote some herself. Poetry and the recitation of prayers played an important role in her mystical experiences. The role of affliction in her mysticism and in her life is important and it will be seen how her stance in the face of affliction is something that marks her thinking. The concept of attention today incorporates issues around the commodification of the attention span, as well as its deficits. This study examines some of these issues and draws forth from the life and work of Simone Weil a more expanded, practical, and reflective understanding of the idea of attention. (shrink)

Patients in a vegetative state/ unresponsive wakefulness syndrome (VS/UWS) pose ethical dilemmas to those involved. Many conflicts occur between professionals and families of these patients. In the Netherlands physicians are supposed to withdraw life sustaining treatment once recovery is not to be expected. Yet these patients have shown to survive sometimes for decades. The role of the families is thought to be important. The aim of this study was to make an inventory of the professional perspective on conflicts in long-term (...) care of patients in VS/UWS. A qualitative study of transcripts on 2 Moral Deliberations (MD’s) in 2 cases of patients in VS/UWS in long-term care facilities. Six themes emerged: 1) Vision on VS/UWS; 2) Treatment and care plan; 3) Impact on relationships; 4) Feelings/attitude; 5) Communication; 6) Organizational aspects. These themes are related to professionals and to what families had expressed to the professionals. We found conflicts as well as contradictory feelings and thoughts to be a general feature in 4 of these themes, both in professionals and families. Conflicts were found in several actors: within families concerning all 6 themes, in nurse teams concerning the theme treatment and care plan, and between physicians concerning all 6 themes. Different visions, different expectations and hope on recovery, deviating goals and contradictory feelings/thoughts in families and professionals can lead to conflicts over a patient with VS/UWS. Key factors to prevent or solve such conflicts are a carefully established diagnosis, clarity upon visions, uniformity in treatment goals and plans, an open and empathic communication, expertise and understanding the importance of contradictory feelings/thoughts. Management should bridge conflicts and support their staff, by developing expertise, by creating stability and by facilitating medical ethical discourses. Shared compassion for the patient might be a key to gain trust and bridge the differences from non-shared to shared decision making. (shrink)

Early-Onset Schizophrenia (EOS) and Attention Deficit-Hyperactivity Disorder (ADHD) are early- onset neurodevelopmental disorders associated with cognitive deficits. The current study represents the first attempt to compare these groups on a comprehensive cognitive test battery in a longitudinal design over 25 years in order to enhance our knowledge of particular patterns resulting from the interaction between normal maturational processes and different illness processes of these disorders. In the baseline study, 19 adolescents with schizophrenia were compared to 20 adolescents with ADHD (...) and 30 healthy controls (HC), all between 12 and 18 years of age. After 13 years (T2) and after 25 years (T3) they were re-evaluated with the cognitive test battery. A cognitive Composite Score was used in a linear mixed model. The EOS group had a significant cognitive stagnation or deterioration from T1 to T2 compared to HC. However, the EOS group had the most positive change from T2 to T3, supporting a stable level of cognitive performance over the 25 year span. The ADHD group improved or had similar development as the HC group from T1 to T2. They continued to improve significantly compared to the HC group from T2 to T3. Individuals in the EOS group performed more impaired on the cognitive composite score compared to the HC group and the ADHD group at all three time points. Results might indicate a neurodevelopmental pathway of EOS with subnormal cognitive development specific in adolescence. In comparison, the ADHD group had a more consistent cognitive maturation supporting a maturational delay hypothesis of ADHD. (shrink)

Dissociation is an important aspect of responses to traumatic events. According to a number of influential theories, it negatively impacts cognitive performance including encoding of the trauma memories, leading to an increased risk of later conditions such as posttraumatic stress disorder . We tested this hypothesis experimentally in two studies by inducing dissociation in the laboratory and investigating the effects on several aspects of cognition, including time estimation, digit and spatial span, and story recall. Dissociation was related to decrements (...) in time estimation, digit span, and story retention, but did not affect perceptual attention, spatial span, or immediate story recall. The results are discussed in the context of theoretical models of PTSD and their implications for official questioning of traumatized individuals such as sexual assault survivors. (shrink)

ABSTRACTPrevious research has shown that emotional stimuli may interfere with working memory processes, but little is known about the process affected. Using a complex span task, the present study investigated the influence of processing negative emotional content on attentional maintenance in WM. In two experiments conducted under articulatory suppression, participants were asked to remember a series of five letters, each of which was followed by an image to be categorised. In half of the trials, the images were negative and (...) in the other half, they were neutral. In both experiments, our results showed longer processing times for emotional stimuli than neutral stimuli, and lower memory performance when participants processed negative stimuli. We propose that emotional stimuli direct more attentional resources towards the processing component of the WM task, thereby reducing the storage capacity available for the items that are to be remembered.

The present study investigates linguistics and cognitive effects of bilingualism with a minority language acquired through school medium education. If bilingualism has an effect on cognition and language abilities, regardless of language prestige or opportunities of use, young adult Gaelic-English speakers attending Gaelic medium education (GME) could have an advantage on linguistic and cognitive tasks targeting executive functions. These will be reported, compared to monolingual speakers living in the same area. Furthermore, this study investigates whether there is a difference in (...) Home Speakers of Gaelic (speakers who had acquired the language at home) compared to New Speakers of this language, i.e. whether an immersive context -as the one offered in medium education- compensates for not being native. A group of 23 monolingual English young adult speakers was compared with a group of 25 bilingual speakers attending a GME school since five years old. Participants were tested on comprehension of a set of sentences with incremental complexity in English, on their capacity to inhibit a distractor using the Test of Everyday attention (TEA) and on their performance in a Digit Span task. A tendency for a better performance on more complex linguistics and cognitive tasks was reported in bilinguals compared to monolinguals with a further advantage for New Speakers compared to Home Speakers. The study supports the idea that being bilingual in a minority language is as beneficial as speaking any other combination of languages. An immersive context of acquisition can be a good ground for developing advantages on both linguistics and cognitive tasks, with a further advantage for New speakers of the language. (shrink)

The harms associated with wireless mobile devices (e.g. smartphones) are well documented. They have been linked to anxiety, depression, diminished attention span, sleep disturbance, and decreased relationship satisfaction. Perhaps what is most worrying from a moral perspective, however, is the effect these devices can have on our autonomy. In this article, we argue that there is an obligation to foster and safeguard autonomy in ourselves, and we suggest that wireless mobile devices pose a serious threat to our capacity (...) to fulfill this obligation. We defend the existence of an imperfect duty to be a ‘digital minimalist’. That is, we have a moral obligation to be intentional about how and to what extent we use these devices. The empirical findings already justify prudential reasons in favor of digital minimalism, but the moral duty is distinct from and independent of prudential considerations. (shrink)

The new information technologies hold out the promise of instantaneous, 24/7 connection and co-presence. But to be everywhere at once is to be effectively nowhere; to be connected to everyone and everything is to be effectively disconnected. Why then do we long for faster connections and fuller connectivity? The answer this paper proposes is that we are trying to fill our existential lack, our radical sense of inadequacy and incompleteness as human beings. From such a perspective, our pursuit of speed (...) and connectivity is doomed to failure insofar as it only exacerbates the condition we are fleeing. Rather than rushing faster, the Buddhist-inspired solution would have us slow down and directly investigate our sense of lack. (shrink)

What can reason do for us and what can't it do? This is the question examined by Herbert A. Simon, who received the 1978 Nobel Prize in Economic Sciences "for his pioneering work on decision-making processes in economic organizations." The ability to apply reason to the choice of actions is supposed to be one of the defining characteristics of our species. In the first two chapters, the author explores the nature and limits of human reason, comparing and evaluating the major (...) theoretical frameworks that have been erected to explain reasoning processes. He also discusses the interaction of thinking and emotion in the choice of our actions. In the third and final chapter, the author applies the theory of bounded rationality to social institutions and human behavior, and points out the problems created by limited attention span human inability to deal with more than one difficult problem at a time. He concludes that we must recognize the limitations on our capabilities for rational choice and pursue goals that, in their tentativeness and flexibility, are compatible with those limits. (shrink)

Did you ever wonder why you are sometimes too tired to watch a film, and would rather watch some TV show? And then, you might end up watching five or six hours and binge watch an entire season, and yet feel too tired to commit yourself to a single 2-hour film piece. The purpose of this paper is threefold. First, I will try to investigate whether there are any ontological differences in the form of a film or a television show. (...) Second, I will try to connect the newest neurological and psychological research regarding binging and attention span and see how seriality influences our brains. I will use the recent neurological findings to try to answer the question of why it seems easier to watch the same number of episodes rather than a single movie. Third, I will use David Lynch's and Mark Frost's third season of Twin Peaks as an example illustrating the blurry borders between a television show and a film, while contrasting it to the binge-watching phenomenon.

The public sphere should be regulated so the distribution of political speech does not correlate with the distribution of income or wealth. A public sphere where people can fund any political speech from their private holdings is epistemically defective. The argument has four steps. First, if political speech is unregulated, the rich predictably contribute a disproportionate share. Second, wealth tends to correlate with substantive political perspectives. Third, greater quantities of speech by the rich can “drown out” the speech of the (...) poor, because of citizens’ limited attention span for politics. Finally, the normative problem with all this is that it reduces the diversity of arguments and evidence citizens become familiar with, reducing the quality of their political knowledge. The clearest implication of the argument is in favour of strict contribution limits and/or public funding for formal political campaigns, but it also has implications for more informal aspects of the public sphere.

As science learns more about how the brain works, and fails to work, the possibility for developing “cognition enhancers” becomes more plausible. And the demand for drugs that can help us think faster, remember more, and focus more keenly has already been demonstrated by the market success of drugs like Ritalin, which tames the attention span, and Prozac, which ups the competitive edge. The new drug Aricept, which improves memory, most likely will join them. Whether such drugs are (...) good for individuals, or for society, is an open question, one that demands far more public discussion. (shrink)

Human relations are driven by social events—people interact, exchange information, share knowledge and emotions, and gather news from mass media. These events leave traces in human memory, the strength of which depends on cognitive factors such as emotions or attention span. Each trace continuously weakens over time unless another related event activity strengthens it. Here, we introduce a novel cognition-driven social network model that accounts for cognitive aspects of social perception. The model explicitly represents each social interaction as (...) a trace in human memory with its corresponding dynamics. The strength of the trace is the only measure of the influence that the interactions had on a person. For validation, we apply our model to NetSense data on social interactions among university students. The results show that CogSNet significantly improves the quality of modeling of human interactions in social networks. (shrink)

The resulting separation of the two disciplines was probably inevitable, but there is a question whether it has not gone too far and also whether it has actually gone as far as is commonly supposed. Do psychologists succeed in avoiding philosophy, and do philosophers succeed in maintaining their aloofness on analytic, methodological or categorial levels, with nothing implied as to mental activity or behavior? The jurisdictional problem cannot be resolved if each side simply retreats before the other, back toward its (...) inner citadel: experiment, on the one hand, and logic, on the other. For experimental results have to be interpreted, and interesting problems of method and sometimes epistemology are involved which experiment cannot settle. Similarly, if the distinction between analytic and synthetic judgments depends, in the final count, on attention-span or memory-span, and a theory of the meaning of proper names can be tested by a canvas of actual usage, then even logic is not autonomous.

In lieu of an abstract, here is a brief excerpt of the content:Clinical CommentarySim Kang, Associate ProfessorRegarding the question of whether to disclose the incidental finding or not to the 72-year-old subject, one needs to consider several issues pertaining to the elderly subject, investigator team, informed consent process, illness under examination and wider societal and cultural context. First, in terms of the subject, would keeping the incidental finding secret in the context of the informed consent be respectful of the wishes (...) of the subject? One needs to bear in mind that consent was taken with the understanding that assessments will not be further shared with the subject as the assessments were done in the research study to generate new data and were not part of clinical evaluation or treatment. In one sense, autonomy of the subject in agreeing and consenting to the study investigations must be respected and the subject is comfortable that no results of the extensive assessments (blood tests and brain scans which are performed at baseline and annually for three years prospectively) will be proffered in the course of the project. At a more personal level, it may also be that the subject prefers not to know of any incidental findings even if present, which in some cases may be related to cultural notions of abnormal findings and ill health.Second, from the standpoint of the research team, would awareness of the space-occupying lesion but not informing the subject constitute a breach of ethical principles of beneficence and non maleficence? When the subject is enrolled in a research study, it is understood that the balance between research risks and benefits should have been evaluated in favour of the latter. Although more needs to be clarified to determine the clinical significance of the lesion, there is a possibility that the lesion may be malignant which would pose [End Page 289] further challenges. If the lesion is detected early, there may be a likelihood of early intervention, including surgical or non-surgical options. If the lesion of undetermined stage at present is not treated expediently and expeditiously, is there a possibility of it progressing to a stage when delayed treatment may be less effective? In this aspect, the welfare of the subject needs to be kept in mind. Even if nondisclosure is opted, is it just to allow the subject to continue in the longitudinal study if the small intracerebral lesion turns out to be malignant or that treatment may be rendered less effective over time?Third, with regard to the informed consent procedure, does the patient fully appreciate the details and implications of the study including not sharing laboratory or neuroimaging evaluations? For the process of informed consent to be meaningful, there are three elements that need to be present, namely adequate and appropriate disclosure of details about the study, demonstration of understanding of the information presented, as well as voluntariness in participation. Pertaining to adequate disclosure, was there appropriate disclosure and discussion of some of the key aspects of the study, including prospective nature lasting three years, repeated measurements and no sharing of details of assessments? The subject needs to have an appreciation of the impact of the information beyond intellectual comprehension. Was he or she cognisant of the number of visits over the entire course of the study as well as the amount of time involved for each visit? What was the response of the subject when it was made known that additional information obtained from the study evaluations will not be revealed or disclosed?Factors that may influence the understanding in this case include older age with possible easier fatigability and shorter attention span, severity of illness with related level of cognitive impairment, educational level, and familiarity with research procedures, all of which are unclear in this case at this point. With respect to voluntariness, was there any undue coercion or influence that may compromise the respect for autonomy of the research subject? It is noteworthy that the team has painstakingly committed to retake the consent before each follow up (thrice over three years) and that the subject can withdraw from the participation in the study at any point in time. Were there factors that may affect the willingness of the subject... (shrink)

Buddhism is all about training the mind, and boot camp is an ideal training method for this generation's short attention span. The chapters in this small book can be read in any order, and are simple and easy to understand. Each story, inspirational quote, and teaching offers mindfulness-enhancing techniques that anyone can relate to. You don't need to be a Buddhist to find the Buddha's teachings motivational. As the Dalai Lama says, "Don't try to use what you learn (...) from Buddhism to be a Buddhist; use it to be a better whatever-you-already-are." So whether it's Mother Teresa's acts of charity, Gandhi's perseverance, or your aunt Betty's calm demeanor, as long as you're motivated to be better today than you were yesterday, it doesn't matter who inspires you. Regardless of religion, geographical region, race, ethnicity, color, gender, sexual orientation, age, ability, flexibility, or vulnerability, if you do good you feel good, and if you do bad you feel bad. Buddhism isn't just about meditating. It's about rolling up your sleeves to relieve some of the suffering in the world. If you are ready to be a soldier of peace in the army of love, welcome to Buddhist Boot Camp! (shrink)

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing (...) to adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

Understanding how people comprehend visual narratives (including picture stories, comics, and film) requires the combination of traditionally separate theories that span the initial sensory and perceptual processing of complex visual scenes, the perception of events over time, and comprehension of narratives. Existing piecemeal approaches fail to capture the interplay between these levels of processing. Here, we propose the Scene Perception & Event Comprehension Theory (SPECT), as applied to visual narratives, which distinguishes between front-end and back-end cognitive processes. Front-end processes (...) occur during single eye fixations and are comprised of attentional selection and information extraction. Back-end processes occur across multiple fixations and support the construction of event models, which reflect understanding of what is happening now in a narrative (stored in working memory) and over the course of the entire narrative (stored in long-term episodic memory). We describe relationships between front- and back-end processes, and medium-specific differences that likely produce variation in front-end and back-end processes across media (e.g., picture stories vs. film). We describe several novel research questions derived from SPECT that we have explored. By addressing these questions, we provide greater insight into how attention, information extraction, and event model processes are dynamically coordinated to perceive and understand complex naturalistic visual events in narratives and the real world.

The public sphere should be regulated so the distribution of political speech does not correlate with the distribution of income or wealth. A public sphere where people can fund any political speech from their private holdings is epistemically defective. The argument has four steps. First, if political speech is unregulated, the rich predictably contribute a disproportionate share. Second, wealth tends to correlate with substantive political perspectives. Third, greater quantities of speech by the rich can “drown out” the speech of the (...) poor, because of citizens’ limited attention span for politics. Finally, the normative problem with all this is that it reduces the diversity of arguments and evidence citizens become familiar with, reducing the quality of their political knowledge. The clearest implication of the argument is in favour of strict contribution limits and/or public funding for formal political campaigns, but it also has implications for more informal aspects of the public sphere.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:BoredomWalter E. BromanBoredom, by Patricia Meyer Spacks; xii & 289 pp. Chicago: University of Chicago Press, 1995, $24.95 paper.Scholars who have been immersed in the eighteenth century are often imbued with a penchant for common sense and develop a rich, lucid style. Professor Spacks exemplifies these qualities admirably. In spite of the sludgy title, this is a stimulating and rewarding book. Until now my only thinking about boredom (...) has happened while watching goldfish or cows and wondering if they were slowly perishing of boredom. Otherwise, boredom has been a gray experience accompanying committee meetings or reading insurance prose, but scarcely a matter for philosophy. Professor Spacks shows that there is much here for serious thought. She traces the history of boredom, mainly as manifested in novels. “This book’s project is to investigate boredom’s imaginative functions during the past two and a half centuries, mainly in England, where speakers first labeled the condition early in the second half of the eighteenth century” (p. 6). In this period the idea of boredom was still influenced by Christian thought. Thus, Johnson saw Boswell’s boredom in Scotland as a lapse in Christian morality, a lack of personal resources. Johnson felt the universal power of boredom; it invaded even “the Happy Valley of Rasselas,” but he insisted on the moral duty of opposing it with spirited effort. Women writers of the period are pictured as doing just that—heroically defeating a boredom imposed upon women by society through the vivacity and energy of language in their epistles and narration. Professor Spacks depicts the early nineteenth century as afflicting later decades with sensibility and didactic tedium and developing complex new aspects of boredom as a mode of aggression that could shrivel people, arts, and society. “To real aristocrats belongs the repudiation of feeling—passion and compassion—that constitutes boredom” (p. 201). In the twentieth century boredom becomes ubiquitous and has “enormous and essentially unalterable power” (p. ix). This century is like a fulfillment of Pope’s vision of universal dullness at the end of The Dunciad.During the course of this history we become almost convinced that in the eighteenth and nineteenth centuries women hunkered in a cotton-wrapped male-dominated world which went to great lengths to normalize female boredom. “Often tedium attends compliant virtue” (p. 78). This idea of [End Page 506] oppressed and suffering women is repeated in the text to the point of—well—boring the reader. From my reading in general and from this book I garnered the impression that eighteenth-century women were for the most part tough, alive, and intelligent masters of boredom. I can almost hear their spirits crying, “save the pity!”Professor Spacks fulfills the older mission of criticism to promote interest and attention, and provide insight. Like literature, this mission aims to defeat boredom. We are rewarded with a brilliant discussion of Sense and Sensibility, showing us how Austen’s subtle rhetoric guides the reader’s perception of what is interesting—to learn to find seemingly dull Elinor and Edward actually interesting, to thwart our shallower driftings. In a similar vein with moral bearings Professor Spacks manages to stir interest in a discussion of Wordsworth’s “The Idiot Boy.” We recall how Wordsworth militated against the human inclination to depend upon gross and violent stimulants. He proposed that we ought to be interested in what is moral and thereby genuinely interesting. In “The Idiot Boy” he aimed to enlarge our moral attention span to embrace the lowly and unlikely. I began to feel much less like a moral derelict when Professor Spacks admitted that she too finds “The Idiot Boy” boring.This is such a rewarding book that I feel uncomfortably churlish in pointing out that aspects of the book are irksome. In general, her sentences are beautiful, but in large tracts of the book we find an Emersonian discursiveness where the discussions are crumbly and anfractuous, tacking from this to that. We don’t get enough sustained driving down a clear track. She suggests in passing that Hannah More’s Coelebs is boring to the later nineteenth century when people become more concerned with inner conflicts and... (shrink)

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory handling idiosyncratic lexical knowledge and procedural memory handling rule-governed knowledge of grammar.We experimentally contrast the processing of morphology (case and aspect), syntax (subordination), and lexical semantics (collocations) in a healthy L1 (...) population of Polish, a language rich in form distinctions. We study the processing of these four types under two conditions: a single task condition in which the grammaticality of stimuli was judged and a concurrent task condition in which grammaticality judgments were combined with a digit span task. Dividing attention impedes access to declarative memory while leaving procedural memory unaffected and hence constitutes a test that dissociates which types of linguistic information each long-term memory construct subserves.Our findings confirm the existence of a distinction between lexicon and grammar as a generative, dual-route model would predict, but the distinction is graded, as usage-based models assume: the hypothesized grammar–lexicon opposition appears as a continuum on which grammatical phenomena can be placed as being more or less “ruly” or “idiosyncratic.” However, usage-based models, too, need adjusting as not all types of linguistic knowledge are proceduralized to the same extent. This move away from a simple dichotomy fundamentally changes how we think about memory for language, and hence how we design and interpret behavioral and neuroimaging studies that probe into the nature of language cognition.
