Humans are experts in cooperating with each other when trying to accomplish tasks they cannot achieve alone. Recent studies of joint action have shown that when performing tasks together people strongly rely on the neurocognitive mechanisms that they also use when performing actions individually, that is, they predict the consequences of their co‐actor’s behavior through internal action simulation. Context‐sensitive action monitoring and action selection processes, however, are relatively underrated but crucial ingredients of joint action. In the present paper, we try (...) to correct the somewhat simplified view on joint action by reviewing recent studies of joint action simulation, monitoring, and selection while emphasizing the intricate interrelationships between these processes. We complement our review by defining the contours of a neurologically plausible computational framework of joint action. (shrink)

Research has shown that observers automatically align their attention with another’s gaze direction. The present study investigates whether inferring another’s attended location affects the observer’s attention in the same way as observing their gaze direction. In two experiments, we used a laterally oriented virtual human head to prime one of two laterally presented targets. Experiment 1 showed that, in contrast to the agent with closed eyes, observing the agent with open eyes facilitated the observer’s alignment of attention with the primed (...) target location. Experiment 2, where either sunglasses or occluders concealed the agent’s eye direction, showed that only the agent with the sunglasses facilitated the observer’s alignment of attention with the target location. Taken together, the data demonstrate that head orientation alone is not sufficient to trigger a shift in the observer’s attention, that gaze direction is crucial to this process, and that inferring the region to which another person is attending does facilitate the alignment of attention.

We focus on Byrne & Russon's argument that program-level imitation is driven by hierarchically organized goals, and the related claim that to establish whether observed behavior is evidence of program-level imitation, empirical studies of imitation must use multi-stage actions as imitative tasks. We agree that goals play an indispensable role in the generation of action and imitative behavior but argue that multi-goal tasks, not only multi-stage tasks, reveal program-level imitation.

The present commentary considers the question of what must be learned in different types of motor skills, thereby limiting the question of what should be adjusted in the APG model in order to explain successful learning. It is concluded that an open loop model like the APG might well be able to describe the learning pattern of motor skills in a stable, predictable environment. Recent research on saccadic plasticity, however, illustrates that motor skills performed in an unpredictable environment depend heavily (...) on sensory (mostly visual) feedback, [HOUK et al.].

Three experiments investigated the nature of visuo-auditory crossmodal cueing in a triadic setting: participants had to detect an auditory signal while observing another agent’s head facing one of the two laterally positioned auditory sources. Experiment 1 showed that when the agent’s eyes were open, sounds originating on the side of the agent’s gaze were detected faster than sounds originating on the side of the agent’s visible ear; when the agent’s eyes were closed this pat-tern of responses was reversed. Two additional (...) experiments showed that the results were sensitive to whether participants could infer a hearing function on the part of the agent. When no ear was depicted on the agent, only a gaze-side advantage was observed , but when the agent’s ear was covered , an ear side advantage was observed only when hearing could still be inferred but not when hearing was inferred to be diminished . The findings are discussed in the context of inferential and simulation processes and joint attention mechanisms. (shrink)

Although applauding Pickering & Garrod's (P&G's) attempt to ground language use in the ideomotor perception-action link, which provides an of embodied social interaction, we suggest that it needs to be complemented by an additional control mechanism that modulates its operation in the service of the language users' communicative intentions. Implications for intergroup relationships and intercultural communication are discussed.

ABSTRACTWhen processing information about human faces, we have to integrate different sources of information like skin colour and emotional expression. In 3 experiments, we investigated how these features are processed in a top-down manner when task instructions determine the relevance of features, and in a bottom-up manner when the stimulus features themselves determine process priority. In Experiment 1, participants learned to respond with approach-avoidance movements to faces that presented both emotion and colour features. For each participant, only one of these (...) two features was task-relevant while the other one could be ignored. In contrast to our predictions, we found better learning of task-irrelevant colour when emotion was task-relevant than vice versa. Experiment 2 showed that the learning of task-irrelevant emotional information was improved in general when participants’ awareness was increased by adding NoGo-trials. Experiment 3 replicated these results... (shrink)

According to embodied theories of language (ETLs), word meaning relies on sensorimotor brain areas, generally dedicated to acting and perceiving in the real world. More specifically, words denoting actions are postulated to make use of neural motor areas, while words denoting visual properties draw on the resources of visual brain areas. Therefore, there is a direct correspondence between word meaning and the experience a listener has had with a word's referent on the brain level. Behavioral and neuroimaging studies have provided (...) evidence in favor of ETLs; however, recent studies have also shown that sensorimotor information is recruited in a flexible manner during language comprehension (e.g., Raposo et al. ; Van Dam et al., ), leaving open the question as to what level of language processing sensorimotor activations contribute. In this study, we investigated the time course of modality-specific contributions (i.e., the contribution of action information) as to word processing by manipulating both (a) the linguistic and (b) the action context in which target words were presented. Our results demonstrate that processes reflecting sensorimotor information play a role early in word processing (i.e., within 200 ms of word presentation), but that they are sensitive to the linguistic context in which a word is presented. In other words, when sensorimotor information is activated, it is activated quickly; however, specific words do not reliably activate a consistent sensorimotor pattern. (shrink)

Single cell recordings in monkeys provide strong evidence for an important role of the motor system in action understanding. This evidence is backed up by data from studies of the (human) mirror neuron system using neuroimaging or TMS techniques, and behavioral experiments. Although the data acquired from single cell recordings are generally considered to be robust, several debates have shown that the interpretation of these data is far from straightforward. We will show that research based on single-cell recordings allows for (...) unlimited content attribution to mirror neurons. We will argue that a theoretical analysis of the mirroring process, combined with behavioral and brain studies, can provide the necessary limitations. A complexity analysis of the type of processing attributed to the mirror neuron system can help formulate restrictions on what mirroring is and what cognitive functions could, in principle, be explained by a mirror mechanism. We argue that processing at higher levels of abstraction needs assistance of non-mirroring processes to such an extent that subsuming the processes needed to infer goals from actions under the label ?mirroring? is not warranted.

A dual-code model of number processing needs to take into account the difference between a number symbol and its meaning. The transition of automatic non-abstract number representations into intentional abstract representations could be conceptualized as a translation of perceptual asemantic representations of numerals into semantic representations of the associated magnitude information. The controversy about the nature of number representations should be thus related to theories on embodied grounding of symbols.

People cannot understand intentions behind observed actions by direct simulation, because goal inference is highly context dependent. Context dependency is a major source of computational intractability in traditional information-processing models. An embodied embedded view of cognition may be able to overcome this problem, but then the problem needs recognition and explication within the context of the new, layered cognitive architecture.

This study considers one of the cognitive mechanisms underlying the development of second language vocabulary in children: The differentiation and sharpening of lexical representations. We propose that sharpening is triggered by an implicit comparison of similar representations, a process we call contrasting. We investigate whether integrating contrasting in a learning method in which children contrast orthographically and semantically similar L2 words facilitates learning of those words by sharpening their new lexical representations. In our study, 48 Dutch-speaking children learned unfamiliar orthographically (...) and semantically similar English words in a multiple-choice learning task. One half of the group learned the similar words by contrasting them, while the other half did not contrast them. Their word knowledge was measured immediately after learning as well as 1 week later. Contrasting was found to facilitate learning by leading to more precise lexical representations. However, only highly skilled readers benefitted from contrasting. Our findings offer novel insights into the development of L2 lexical representations from fuzzy to more precise, and have potential implications for education. (shrink)

Much of the debate about identity in recent decades has been about personal identity, and specifically about personal identity over time, but identity generally, and the identity of things of other kinds, have also attracted attention. Various interrelated problems have been at the centre of discussion, but it is fair to say that recent work has focussed particularly on the following areas: the notion of a criterion of identity; the correct analysis of identity over time, and, in particular, the disagreement (...) between advocates of perdurance and advocates of endurance as analyses of identity over time; the notion of identity across possible worlds and the question of its relevance to the correct analysis of de re modal discourse; the notion of contingent identity; the question of whether the identity relation is, or is similar to, the composition relation; and the notion of vague identity. A radical position, advocated by Peter Geach, is that these debates, as usually conducted, are void for lack of a subject matter: the notion of absolute identity they presuppose has no application; there is only relative identity. Another increasingly popular view is the one advocated by Lewis: although the debates make sense they cannot genuinely be debates about identity, since there are no philosophical problems about identity. Identity is an utterly unproblematic notion. What there are, are genuine problems which can be stated using the language of identity. But since these can be restated without the language of identity they are not problems about identity. (For example, it is a puzzle, an aspect of the so-called “problem of personal identity”, whether the same person can have different bodies at different times. But this is just the puzzle whether a person can have different bodies at different times. So since it can be stated without the language of personal “identity”, it is not a problem about identity, but about personhood.) This article provides an overview of the topics indicated above, some assessment of the debates and suggestions for further reading. (shrink)

Used by more than one million students around the world since its original publication, this introductory philosophy text makes accessible a wide range of philosophical issues closely related to everyday life. Emphasizing personal and immediate questions, the authors approach introductory philosophy through basic human questions rather than focusing on methodology or the history of thought. The text presents vital questions of contemporary interest in an overall framework of enduring concepts, interweaving coverage of various topics in art, history, and education. It (...) covers a variety of types of philosophy in depth, and both western and eastern perspectives are represented. Ideal for students who have no background in philosophy, Living Issues in Philosophy, 9/e simplifies technical language wherever possible; unfamiliar terms are clearly defined upon first appearance and in the end-of-chapter glossaries. Additional pedagogical features include exercises, chapter summaries, and annotated bibliographies at the end of every chapter. The text also features photo biographies of major philosophers and short excerpts from philosophical classics. (shrink)

The American University Publications In From its inception Philosophy has continued the direction stated in the sub-title of the initial volume that of probing new directions in philosophy. As the series has developed these probings of new directions have taken the two fold direction of exploring the relationships between the disparate traditions of twentieth century philosophy and with developing new insights into the foundations of some enduring philosophic problems. This present volume continues both of these directions. The interaction between twentieth-century (...) Anglo-Saxon and Continental philosophy which was an implicit theme of our first and third volumes and the explicit subject of our second volume is here continued in a series of studies on major figures and topics in each tradition. In the context of these interpretative studies, Professor Durfee returns again and again to the question of the relationships between the will and the reason, and explores the conflicting goals of creativity and objectivity in formulating a philosophic position. In so doing he raises the issue as his title suggests - of the foundations of philosophy itself. He seriously challenges the belief common to both pheomenology and analytic philosophy that philosophizing can be a presuppositionless activity, objectively persued independent of the personal (and, perhaps, arbitrary) commitments of the philosopher. This issue, critical as it is to all forms of philosophy, is surely a worthy one for a series such as ours. (shrink)

When the whole is greater than the sum of the parts--indeed, so great that the sum far transcends the parts and represents something utterly new and different--we call that phenomenon emergence. When the chemicals diffusing in the primordial waters came together to form the first living cell, that was emergence. When the activities of the neurons in the brain result in mind, that too is emergence. In The Emergence of Everything, one of the leading scientists involved in the study of (...) complexity, Harold J. Morowitz, takes us on a sweeping tour of the universe, a tour with 28 stops, each one highlighting a particularly important moment of emergence. For instance, Morowitz illuminates the emergence of the stars, the birth of the elements and of the periodic table, and the appearance of solar systems and planets. We look at the emergence of living cells, animals, vertebrates, reptiles, and mammals, leading to the great apes and the appearance of humanity. He also examines tool making, the evolution of language, the invention of agriculture and technology, and the birth of cities. And as he offers these insights into the evolutionary unfolding of our universe, our solar system, and life itself, Morowitz also seeks out the nature of God in the emergent universe, the God posited by Spinoza, Bruno, and Einstein, a God Morowitz argues we can know through a study of the laws of nature. Written by one of our wisest scientists, The Emergence of Everything offers a fascinating new way to look at the universe and the natural world, and it makes an important contribution to the dialogue between science and religion.

During the 1992–1993 academic year, Harold Garfinkel offered a graduate seminar on Ethnomethodology in the Sociology Department at the University of California, Los Angeles. One topic that was given extensive coverage in the seminar has not been discussed at much length in Garfinkel’s published works to date: Aron Gurwitsch’s treatment of Gestalt theory, and particularly the themes of “phenomenal field” and “praxeological description”. The edited transcript of Garfinkel’s seminar shows why he recommended that “for the serious initiatives of ethnomethodological (...) investigations […] Gurwitsch is a theorist we can’t do without”. Garfinkel’s ethnomethodological “misreading” is not a mistaken reading, but is more a matter of taking Gurwitsch’s phenomenological demonstrations of Gestalt contextures in phenomenal fields and transposing them for making detailed, concrete observations and descriptions of organizationally achieved social phenomena. Where Gurwitsch addresses the organization of perception as an autochthonous achievement, inherent to the stream and field of individual consciousness, Garfinkel extends and elaborates this field into the social world of enacted practices. The April 1993 seminar also is rich with brief asides and digressions in which Garfinkel comments about his use of Alfred Schutz, his attitude toward publishing, his relationship with Erving Goffman, and many other matters.

Another title in the reissued Oxford Classic Texts in the Physical Sciences series, Jeffrey's Theory of Probability, first published in 1939, was the first to develop a fundamental theory of scientific inference based on the ideas of Bayesian statistics. His ideas were way ahead of their time and it is only in the past ten years that the subject of Bayes' factors has been significantly developed and extended. Until recently the two schools of statistics were distinctly different and set apart. (...) Recent work has changed all that and today's graduate students and researchers all require an understanding of Bayesian ideas. This book is their starting point. (shrink)

The prevention, treatment and management of disease are closely linked to how the causes of a particular disease are explained. For multi-factorial conditions, the causal explanations are inevitably complex and competing models may exist to explain the same condition. Selecting one particular causal explanation over another will carry practical and ethical consequences that are acutely relevant for health policy. In this paper our focus is two-fold; the different models of causal explanation that are put forward within current scientific literature for (...) the high and rising prevalence of the common complex conditions of coronary artery disease and type 2 diabetes mellitus ; and how these explanations are taken up within national health policy guidelines. We examine the causal explanations for these two conditions through a systematic database search of current scientific literature. By identifying different causal explanations we propose a three-tier taxonomy of the most prominent models of explanations: evolutionary, lifecourse, and lifestyle and environment. We elaborate this taxonomy with a micro-level thematic analysis to illustrate how some explanations are semantically and rhetorically foregrounded over others. We then investigate the uptake of the scientific causal explanations in health policy documents with regard to the prevention and management recommendations of current National Service Frameworks for CAD and T2D. Our findings indicate a lack of congruence between the complexity and frequent overlap of causal explanations evident in the scientific literature and the predominant focus on lifestyle recommendations found in the mainstream health policy documents.

But we are sometimes mistaken about our experiences, and followers of other religions also provide impressive testimonies to support their religious beliefs.

Background: Although inclusive education is widely discussed, its implementation has not, arguably, been far-reaching. There remains a lack of specific, targeted approaches towards fully including learners with physical and mental impairments in the educational space. Objectives: This study investigated the extent of the inclusion of learners with autism spectrum disorder (ASD) in three schools in Johannesburg. Method: A qualitative interpretivist design was adopted. Teachers who work with learners with ASD were interviewed using open-ended questions. The sampled data were analysed using (...) thematic analysis, making use of both a priori codes and emergent codes that arose from the open-ended questions. Results: The findings reveal numerous pedagogic strategies such as differentiation, scaffolding, use of visual cues, group work and collaboration that can include learners with ASD in the classroom space. Conclusion: Teacher collaboration and teacher training are vital in ensuring that learners with ASD are fully included in the classroom space. (shrink)
