Core mechanisms in "theory of mind"

philosophy — thomasr @ 6:03 am

Abstract Our ability to understand the thoughts and feelings of other people does not initially develop as a theory but as a mechanism. The ‘theory of mind’ mechanism (ToMM) is part of the core architecture of the human brain, and is specialized for learning about mental states. Impaired development of this mechanism can have drastic effects on social learning, seen most strikingly in the autistic spectrum disorders. ToMM kick-starts belief-desire attribution but effective reasoning about belief contents depends on a process of selection by inhibition. This selection process (SP) develops slowly through the preschool period and well beyond. By modeling the ToMM-SP as mechanisms of selective attention, we have uncovered new empirical phenomena. We propose that early “theory of mind” is a modular heuristic process of domain-specific learning. Link

The Origin of Mind

books — thomasr @ 4:31 am

Darwin considered an understanding of the evolution of the human mind and brain to be of major importance to the evolutionary sciences. This ground-breaking book sets out a comprehensive, integrated theory of why and how the human mind has developed to function as it does. Geary proposes that human motivational, affective, behavioral, and cognitive systems have evolved to process social and ecological information (e.g., facial expressions) that covaried with survival or reproductive options during human evolution. Further, he argues that the ultimate focus of all of these systems is to support our attempts to gain access to and control of resources — more specifically, the social (e.g., matees), biological (e.g., food), and physical (e.g., territory) resources that supported successful survival and reproduction over time. In this view, Darwin’s conceptualization of natural selection as a “struggle for existence” becomes, for us, a struggle with other human beings for control of the available resources. This struggle provides a means of integrating modular brain and cognitive systems such as language with those brain and cognitive systems that support general intelligence. To support his arguments, Geary draws upon an impressive array of recent findings in cognitive science and neuroscience, as well as primatology, anthropology, and sociology. The book also explores a number of issues that are of interest in modern society, including how general intelligence relates to academic achievement, occupational status, and income. Readers will find this book a thought-provoking read and an impetus for new theories of mind.
