Can social interaction constitute social cognition

An important shift is taking place in social cognition research, away from a focus on the individual mind and toward embodied and participatory aspects of social understanding. Empirical results already imply that social cognition is not reducible to the workings of individual cognitive mechanisms. To galvanize this interactive turn, we provide an operational definition of social interaction and distinguish the different explanatory roles - contextual, enabling and constitutive - it can play in social cognition. We show that interactive processes are more than a context for social cognition: they can complement and even replace individual mechanisms. This new explanatory power of social interaction can push the field forward by expanding the possibilities of scientific explanation beyond the individual.

The earliest sense of self and others: Merleau-Ponty and recent developmental studies

Recent studies in developmental psychology have found evidence to suggest that there exists an innate system that accounts for the possibilities of early infant imitation and the existence of phantom limbs in cases of congenital absence of limbs. These results challenge traditional assumptions about the status and development of the body schema and body image, and about the nature of the translation process between perceptual experience and motor ability. Merleau-Ponty, who was greatly influenced by his study of developmental psychology, and whose phenomenology of perception was closely tied to the concept of the body schema, accepted these traditional assumptions. They also informed his philosophical conclusions concerning the experience of self and others. We re-examine issues involved in understanding self and others in light of the more recent research in developmental psychology. More specifically our re-examination challenges a number of Merleau-Pontys conclusions and suggests, in contrast, that the newborn infant is capable of a rudimentary differentiation between self and non-self.

On agency and body-ownership: Phenomenological and neurocognitive reflections

The recent distinction between sense of agency and sense of body-ownership has attracted considerable empirical and theoretical interest. The respective contributions of central motor signals and peripheral afferent signals to these two varieties of body experience remain unknown. In the present review, we consider the methodological problems encountered in the empirical study of agency and body-ownership, and we then present a series of experiments that study the interplay between motor and sensory information. In particular, we focus on how multisensory signals interact with body representations to generate the sense of body-ownership, and how the sense of agency modulates the sense of body-ownership. Finally, we consider the respective roles of efferent and afferent signals for the experience of ones own body and actions, in relation to self-recognition and the recognition of other peoples actions. We suggest that the coherent experience of the body depends on the integration of efferent information with afferent information in action contexts. Overall, whereas afferent signals provide the distinctive content of ones own body experience, efferent signals seem to structure the experience of ones own body in an integrative and coherent way.

Understanding Interpersonal Problems in Autism: Interaction Theory as An Alternative to Theory of Mind

I argue that theory theory approaches to autism offer a wholly inadequate explanation of autistic symptoms because they offer a wholly inadequate account of the non-autistic understanding of others. As an alternative I outline interaction theory, which incorporates evidence from both developmental and phenomenological studies to show that humans are endowed with important capacities for intersubjective understanding from birth or early infancy. As part of a neurophenomenological analysis of autism, interaction theory offers an account of interpersonal problems that is fully consistent with the variety of social and nonsocial symptoms found in autism.

Neurocognitive models of schizophrenia: a neurophenomenological critique.

This paper argues that Frith’s (1992) account of the positive symptoms of schizophrenia in terms of a disruption of metarepresentational self-monitoring is inadequate in several specific ways. More generally, this paper argues against top-down explanations for the loss of the sense of agency in such symptoms. In addition, even if delusions of control might be explained by problems involved in motor control mechanisms involving efference copy and comparators, there are good reasons why the same model cannot explain thought insertion. In place of such neurocognitive explanations, the author develops a neurophenomenological explanation for the loss of the sense of agency and the misattribution of actions and thoughts to others in such symptoms.

Inference or interaction: social cognition without precursors

In this paper I defend interaction theory (IT) as an alternative to both theory theory (TT) and simulation theory (ST). IT opposes the basic suppositions that both TT and ST depend upon. I argue that the various capacities for primary and secondary intersubjectivity found in infancy and early childhood should not be thought of as precursors to later developing capacities for using folk psychology or simulation routines. They are not replaced or displaced by such capacities in adulthood, but rather continue to operate as our ordinary and everyday basis for social cognition. I also argue that enactive perception rather than implicit simulation is the best model for explaining these capacities.

Experimenting with phenomenology

We review the use of introspective and phenomenological methods in experimental settings. We distinguish different senses of introspection, and further distinguish phenomenological method from introspectionist approaches. Two ways of using phenomenology in experimental procedures are identified: first, the neurophenomenological method, proposed by Varela, involves the training of experimental subjects. This approach has been directly and productively incorporated into the protocol of experiments on perception. A second approach may have wider application and does not involve training experimental subjects in phenomenological method. It requires front-loading phenomenological insights into experimental design. A number of experiments employing this approach are reviewed. We conclude with a discussion of the implications for both the cognitive sciences and phenomenology.

The socially extended mind

This paper contrasts conservative and liberal interpretations of the extended mind hypothesis. The liberal view, defended here, considers cognition to be socially extensive, in a way that goes beyond the typical examples (involving notebooks and various technologies) rehearsed in the extended mind literature, and in a way that takes cognition to involve enactive processes (e.g., social affordances), rather than functional supervenience relations. The socially extended mind is in some cases constituted not only in social interactions with others, but also in ways that involve institutional structures, norms, and practices. Some of the common objections to the extended mind are considered in relation to this liberal interpretation. Implications for critical social theory are explored.

Redrawing the map and resetting the time: Phenomenology and the cognitive sciences

We argue that phenomenology can be of central and positive importance to the cognitive sciences, and that it can also learn from the empirical research conducted in those sciences. We discuss the project of naturalizing phenomenology and how this can be best accomplished. We provide several examples of how phenomenology and the cognitive sciences can integrate their research. Specifically, we consider issues related to embodied cognition and intersubjectivity. We provide a detailed analysis of issues related to time-consciousness, with reference to understanding schizophrenia and the loss of the sense of agency. We offer a positive proposal to address these issues based on a neurobiological dynamic-systems model.

Lived Body and Environment

Merleau-Ponty developed a phenomenology of the body that promoted a non-dualistic account of human existence. In this paper I intend to develop Merleau-Pontys analysis further by questioning his account of the body on the issues of body perception, and the bodys relation to its environment. To clarify these issues I draw from both the phenomenological tradition and recent psychological investigations.
