Experimental studies of speech production involving compensations for auditory and somatosensory perturbations and adaptation after training suggest that both types of sensory information are considered to plan and monitor speech production. Interestingly, individual sensory preferences have been observed in this context: subjects who compensate less for somatosensory perturbations compensate more for auditory perturbations, and \textit{vice versa}. We propose to integrate this sensory preference phenomenon in a model of speech motor planning using a probabilistic model in which speech units are characterized (...) both in auditory and somatosensory terms. Sensory preference is implemented in the model according to two approaches. In the first approach, which is often used in motor control models accounting for sensory integration, sensory preference is attributed to the relative precision (i.e., inverse of the variance) of the sensory characterization of the speech motor goals associated with phonological units (which are phonemes in the context of this paper). In the second, ``more original’’ variant, sensory preference is implemented by modulating the sensitivity of the comparison between the predicted sensory consequences of motor commands and the sensory characterizations of the phonemes. We present simulation results using these two variants, in the context of the adaptation to an auditory perturbation, implemented in a 2-dimensional biomechanical model of the tongue. Simulation results show that both variants lead to qualitatively similar results. Distinguishing them experimentally would require precise analyses of partial compensation patterns. However, the second proposed variant implements sensory preference without changing the sensory characterizations of the phonemes. This dissociates sensory preference and sensory characterizations of the phonemes, and makes the account of sensory preference more flexible. Indeed, in the second variant the sensory characterizations of the phonemes can remain stable, when sensory preference varies as a response to cognitive or attentional control. This opens new perspectives for capturing speech production variability associated with aging, disorders and speaking conditions. (shrink)

The trade-off between force and length of muscle as adjusted by neural signals is a critical fact in the dynamics of motor control. Whether we call it “length-tension effect,” “feedback-like,” “invariant condition,” or “spring-like” is unimportant. We must not let semantics or details of representation obscure the basic physics of effects introduced by this trade-off in muscle.

The current research examined whether fair consideration—a social norm that people inherently prefer to confirm—would modulate face recognition. Each neutral face was associated with fair offers or unfair offers via an economic decision task, the Ultimatum Game (UG) task. After the UG, participants were asked to identify the faces of proposers who made different offers. Enhanced memory was observed for fair-related faces compared to unfair-related faces. Furthermore, high trait anxiety was associated with reduced memory for fair-related faces. These results were (...) further confirmed by signal detection theory. The current research provided initial evidence that people showed enhanced memory for faces that made fair offers from the economic decision task, and that high trait anxiety was associated with reduced fair-related memory. Possible neural mechanisms and the implication in economic and social situations have been discussed. (shrink)

Does appraisal co-ordinate emotional responses? Are emotions usually reached via mental representations of relational meaning? This comment considers alternative causal routes in order to assess the centrality of appraisal in the explanation of emotion. Implicit and explicit meaning extraction can certainly help steer the course of emotion-related processes. However, presupposing that appraisals represent the driving force behind all aspects of emotion generation leads to inclusive formulations of appraisal or restrictive formulations of emotion.

In the last decades, the rapid growth of functional brain imaging methodologies allowed cognitive neuroscience to address open questions in philosophy and the social sciences. At the same time, novel insights from cognitive neuroscience research have begun to influence various disciplines, leading to a turn to cognition and emotion in the fields of planning and architectural design. Since 2003, the Academy of Neuroscience for Architecture has been supporting ‘neuro-architecture’ as a way to connect neuroscience and the study of behavioral responses (...) to the built environment. Among the many topics related to multisensory perceptual integration and embodiment, the concept of hapticity was recently introduced, suggesting a pivotal role of touch and haptic imagery in architectural appraisal. Arguments have thus risen in favor of the existence of shared cognitive foundations between hapticity and the supramodal functional architecture of the human brain. Precisely, supramodality refers to the functional feature of defined brain regions to process and represent specific information content in a more abstract way, independently of the sensory modality conveying such information to the brain. Here we highlight some commonalities and differences between the concepts of hapticity and supramodality according to the distinctive perspectives of architecture and cognitive neuroscience. This comparison and connection between these two different approaches may lead to novel observations in regard to people-environment relationships, and even provide empirical foundations for a renewed evidence-based design theory.

The research guided by the correspondence metaphor is lauded for its emphasis on functional analysis, but the term “correspondence” itself needs clarification. Of the two terms in the relationship, only one is well defined. It is suggested that behavior at acquisition needs to be analyzed and that molecular principles from the learning laboratory might be useful in doing so.

In recent years several scholars have wrestled with the term “poetic thought,” suggesting in various ways there is something distinctive about the nature of meaning as it occurs/unfolds through poetry. In this paper I suggest, in part following the lead of Simon Jarvis, that one of the most fruitful lines of inquiry for exploring this idea lies in a consideration of poetic works through the lens of Heidegger’s early phenomenology. Specifically, I argue that one of the keys to understanding poetic (...) thought lies in a flaw within Heidegger’s ontological divisions between substances, equipment and Dasein, as presented in Being and Time. Through an analysis of three poems by Frank O'Hara, I argue poetry that examines and represents the physical world presents a problem for Heidegger when he suggests equipment in the world must necessarily “withdraw” in order for us to engage with it authentically. To address this, the term environment-at-hand is introduced to describe the relationship between art... (shrink)

The model identifies a spatial coordinate frame within which the sensorimotor apparatus produces movement. Its spatial nature simplifies its coupling with spatial reference frames used concurrently by vision and proprioception. While the positional reference frame addresses the performance of spatial tasks, it seems to have little to say about movements involving energy expenditure as the principle component of the task.

I argue that in order to solve the main difficulties confronted by the classical versions of the causal theory of action, it is necessary no just to make room for intentions, considered as irreducible to complexes of beliefs and desires, but also to distinguish among several types of intentions. I present a three-tiered theory of intentions that distinguishes among future-directed intentions, present-directed intentions and motor intentions. I characterize each kind of intention in terms of its functions, its type of content, (...) its dynamics and the rationality and time constraints that bear on it. I then try to show how the difficulties encountered by the causal theory can be solved within this new framework. 1. (shrink)

Trying to understand better the role played by epistemic artifacts in our quest for reliable knowledge, it is interesting to compare their contribution with the one made by the epistemic organs or systems with which we are naturally endowed. This comparative approach may yield the further benefit of an improved understanding of the nature and epistemic functions of our natural epistemic equipment. In this paper, I shall concern myself with comparing the role of a family of instruments, microscopes, with that (...) of visual systems and with assessing the similarities and dissimilarities in accounts of their epistemic contributions.

According to ‘direct social perception’ (DSP) accounts of social cognition, perception may be ‘smart’ enough on its own to inform us about other people’s emotions. Some DSP advocates suggest that ‘smart’ social perception should be conceived along ‘enactive’ lines. In this paper, I suggest that DSP needs social perception to have representational content. This seems in tension with the main versions of enactivism, which deny that perception is representational. I thus present the following challenge to ‘enactive’ versions of DSP: either (...) they show how perception can have the requisite smartness without representational content, which I doubt that they can, or they embrace the orthodox idea that perceptual experiences have representational contents. I also suggest that DSP defenders, whether or not they want to be enactivists, can cheerfully accept the latter idea. (shrink)

Drawing on the material culture of the Ancient Near East as interpreted through Material Engagement Theory, the journey of how material number becomes a conceptual number is traced to address questions of how a particular material form might generate a concept and how concepts might ultimately encompass multiple material forms so that they include but are irreducible to all of them together. Material forms incorporated into the cognitive system affect the content and structure of concepts through their agency and affordances, (...) the capabilities and constraints they provide as the material component of the extended, enactive mind. Material forms give concepts the tangibility that enables them to be literally grasped and manipulated. As they are distributed over multiple material forms, concepts effectively become independent of any of them, yielding the abstract irreducibility that makes a concept like number what it is. Finally, social aspects of material use—collaboration, ordinariness, and time—have important effects on the generation and distribution of concepts. (shrink)

We describe a solution to the redundancy problem related to that proposed in Feldman & Levin's target article. We suggest that the system may use a fixed mapping between commands organized at the level of degrees of freedom and commands to individual muscles. This proposal eliminates the need to maintain an explicit representation of musculoskeletalgeometry in planning movements.

Brain damage may doubly dissociate cognitive modules, but the practice of revealing dissociations is predicated on modularity being true (T. Shallice, 1988). This article questions the utility of assuming modularity, as it examines a paradigmatic double dissociation of reading modules. Reading modules illustrate two general problems. First, modularity fails to converge on a fixed set of exclusionary criteria that define pure cases. As a consequence, competing modular theories force perennial quests for purer cases, which simply perpetuates growth in the list (...) of exclusionary criteria. The first problem leads, in part, to the second problem. Modularity fails to converge on a fixed set of pure cases. The second failure perpetuates unending fractionation into more modules. (shrink)

Placebos are commonly defined as ineffective treatments. They are treatments that lack a known mechanism linking their properties to the properties of the condition on which treatment aims to intervene. Given this, the fact that placebos can have substantial therapeutic effects looks puzzling. The puzzle, we argue, arises from the relationship placebos present between culturally meaningful entities, our intentional relationship to the environment and bodily effects. How can a mere attitude toward a treatment result in appropriate bodily changes? We argue (...) that an ‘enactive’ conception of cognition accommodates and renders intelligible the phenomenon of placebo effects. Enactivism depicts an organism’s adaptive bodily processes, its intentional directedness, and the meaningful properties of its environment as co-emergent aspects of a single dynamic system. In doing so it provides an account of the interrelations between mind, body and world that demystifies placebo effects. (shrink)

Tomasello, Kruger & Ratner relate the evolution of social cognition – the understanding of others' minds – to the evolution of culture. Tomasello et al. conceive of the accumulation of culture as the product of cultural learning, a kind of learning dependent upon recognizing others' intentionality. They distinguish three levels of this recognition: of intention (what isxtrying to do), of beliefs (what doesxthink aboutp), and of beliefs about beliefs (what doesxthinkythinks aboutp). They then tie these levels to three discrete forms (...) of cultural learning – imitative, instructed, and collaborative – which children become capable of when they are 9 months, 4 years, and 6 years old respectively, at least in Western culture where relevant data are available.

The distinction between the space of reasons and the realm of law captures two familiar ways of making events intelligible, by reference to reasons or to natural laws, respectively. I describe a third way of making events intelligible, by explaining them in terms of an agent’s being motivated to do certain things. Explanations of this sort do not involve appealing to reasons for which the agent acts, nor to natural laws under which the event falls. To explain an event in (...) this way is to place it in the space of motivations. I outline the relation between the space of motivations and the space of reasons, and suggest that the space of motivations may serve as a common ground between the positions defended by McDowell and Dreyfus in their recent debate.

Recent developments in the psychological and social sciences have seen a surge of attention to concepts of embodiment. The burgeoning field of embodied cognition, as well as the long-standing tradition of phenomenological philosophy, offer valuable insights for theorising how people come to understand the world around them. However, the implications of human embodiment have been largely neglected by one of the key frameworks for conceptualising the development of social knowledge: Social Representations Theory. This article seeks to spark a dialogue between (...) Social Representations Theory and embodiment research. It outlines the position the body occupies in the existing theoretical and empirical social representations literature, and argues that incorporating concepts gleaned from embodiment research may facilitate a more comprehensive account of the aetiology of social representations. The value of analytic attention to embodiment is illustrated with reference to a recent study of social representations of neuroscience, which suggested that embodied experience can shape the extent to which people engage with certain topics, the conditions under which they do so, and the conceptual and affective content of the ensuing representations. The article argues that expanding Social Representations Theory's methodological and conceptual toolkit, in order to illuminate the interplay between embodied experience and social communication in the development of common-sense knowledge, promises productive directions for empirical and theoretical advancement.

Over the past half-century, the Freeman laboratory has accumulated a large volume of data and a correspondingly extensive interpretive framework centered around an alternative perspective on brain function, that of dynamical systems. The purpose of this paper is first briefly to summarise this work, and bring it into dialogue with other perspectives. The contents of consciousness are seen as an inevitably sparse sample of events in the perception–action cycle. The paper proceeds to an attempt to elucidate the contents of this (...) sparse sample. A critical concept is that of selfhood, and how it presents itself phenomenologically. It is argued that our experience of selfhood is an artifact of the necessity of preservation of subject/object relations. As this part of metaphysics has been badly misunderstood, we scrutinise it at some length in quantum mechanics, biology, and cognition. It is argued that Pattee's approach, while valuable, tends to premature closure on these issues. The paper then proceeds to outline a view on how selfhood is best considered wrt the immune response. This is interrelated with phenomenology, and some data are adduced to support this central hypothesis. Finally, consequences for the social sciences in general are hinted at. (shrink)

While the current discussion on embodied cognition provides valuable accounts of an agent’s bodily sensitivity to instrumental possibilities, in this paper I investigate felt demands as the bodily-affective dimension of the agent’s recognition of deontic powers such as obligations. I argue that there is a close kinship between felt demands and affordances in the stricter sense. I will suggest that what is unique about felt demands on an experiential level is that they involve an evaluative perspective arising from acute or (...) anticipated shame-like feelings. The conclusion is that the recognition of deontic power is also a matter of bodily sensitivity. (shrink)

In his attempt to find cognitive traits that set humans apart from nonhuman primates with respect to tool use, Vaesen overlooks the primacy of the environment toward the use of which behavior evolves. The occurrence of a particular behavior is a result of how that behavior has evolved in a complex and changing environment selected by a unique population.

We develop a semiotic scheme of time, in which time precipitates from the repeated succession of punctuating the progressive tense by the perfect tense. The underlying principle is communication among local participants. Time can thus be seen as a meaning-making, semiotic system in which different time codes are delineated, each having its own grammar and timekeeping. The four time codes discussed are the following: the subjective time having tense, the objective time without tense, the static time without timekeeping, and the (...) inter-subjective time of the E-series. Living organisms adopt a time code called the E-series, which emerges through the local synchronization among organisms or parts of organisms. The inter-subjective time is a new theoretical dimension resulting from the time-aligning activities of interacting agents. Such synchronization in natural settings consists of incessant mutual corrections and adjustments to one’s own punctuation, which is then constantly updated. Unlike the third-person observer keeping the objective time while sitting outside a clock, the second-person negotiators participate in forming the E-series time by punctuating and updating the interface through which different tenses meet at the moment of “now.” Although physics allows physicists to be the only interpreters, the semiotic perspective upends the physical perspective by letting local participants be involved in the interpretation of their mutual negotiations to precipitate that which is called time.
