Attribution Of Intentions

Theory of mind is a cognitive ability, which enables to understand intentions, emotions and beliefs of another person. Because of theory of mind, people are able to interpret behavior of others and adapt to it. Numerous psychiatric impairments are associated with damaged theory of mind and communication with others. The present review analyses the impairments of theory of mind as laying on a continuum from hypermentalization (over-attribution of intentions to others) to hypomentalization (under-attribution of intentions to others) in autism spectrum disorders and schizophrenia. FMRI paradigm of different subprocesses of theory of mind is described (perceptual mind-reading, cognitive theory of mind, “hot” theory of mind and implicit theory of mind). Neural mechanisms of these subprocesses and their impairments in autism spectrum disorder and schizophrenia analyzed.

Perceptual Factors

Abstract Augmentative and alternative communication (AAC) systems often supplement oral communication for individuals with intellectual and communication disabilities. Research with preschoolers without disabilities has demonstrated that two visual–perceptual factors influence speed and/or accuracy of finding a target: the internal color and spatial organization of symbols. Twelve participants with Down syndrome and 12 with autism spectrum disorders (ASDs) completed two search tasks. In one, the symbols were clustered by internal color; in the other, the identical symbols had no arrangement cue. Visual search was superior in participants with ASDs compared to those with Down syndrome. In both groups, responses were significantly faster when the symbols were clustered by internal color. Construction of aided AAC displays may benefit from attention to their physical and perceptual features.
