A number of cognitive and behavioral variables influence the performance in tasks of theory of mind (ToM). Since two of the most important variables, memory and explicit expression, are impaired in schizophrenic patients, the ToM appears inconsistent in these patients. An ideal instrument of ToM should therefore account for deficient memory and impaired ability of these patients to explicitly express intentions. If such an instrument is developed, it should provide information that can be used not only to understand the pathophysiology (...) but also to monitor patients. (shrink)

The effects of aging on the cognitive and affective dimensions of theory of mind , and on the latter’s links with other cognitive processes, such as information processing speed, executive functions and episodic memory, are still unclear. We therefore investigated these effects in young , middle-aged and older adults , using separate subjective and objective assessment tasks. Furthermore, a novel composite task probed participants’ abilities to infer both cognitive and affective mental states in an interpersonal context. Although age affected the (...) objective ToM tests, results revealed a direct aging effect on the second-order ToM, but an indirect one on the first-order cognitive ToM, mediated mainly by age-related declines in executive functions. This study supports the notion of an age-related distinction between subjective and objective assessments of ToM, and confirms that ToM is a complex mental ability with several characteristics reliant to some extent on executive processes.

While many with schizophrenia experience deficits in metacognition it is unclear whether those deficits are related to other features of illness. To explore this issue, the current study classified participants with schizophrenia as possessing a deficit in both awareness of their own emotions and those of others , aware of their own emotions but unaware of the emotions of others and aware of their own emotions and of other’s emotions . Groups were compared on assessments of neurocognitive function, symptoms, and (...) history of sexual trauma. ANCOVA controlling for education found that the group unaware of their own emotions and those of others demonstrated poorer verbal memory, processing speed, executive function, less emotional discomfort and higher levels of disorganization symptoms relative to the other groups. The group aware of their own emotions but not those of others had a significantly higher report of childhood sexual abuse. (shrink)
