The term theory of mind (ToM) refers to the capacity to infer one's own and other persons' mental states. A substantial body of research has highlighted the evolution of ToM in nonhuman primates, its emergence during human ontogeny, and impaired ToM in a variety of neuropsychiatric disorders, including schizophrenia. There is good empirical evidence that(More)
Several studies have demonstrated that patients with schizophrenia are impaired in recognizing emotions from facial expressions and in appreciating other people's mental states--the latter commonly referred to as 'theory of mind.' The question as to how social cognitive skills relate to patients' actual social behavior is, however, largely unanswered. This(More)
BACKGROUND Several studies have suggested a theory of mind (ToM) deficit in schizophrenic disorders. However, the role of interfering variables such as IQ, attention, memory, and severity of the disorder has remained ambiguous. METHODS A theory of mind picture story comprising a sequencing task, a first and a second order false belief test, and a tactical(More)
The ability to infer other persons' mental states and emotions has been termed 'theory of mind'. It represents an evolved psychological capacity most highly developed in humans. The evolutionary origins of theory of mind can be traced back in extant non-human primates; theory of mind probably emerged as an adaptive response to increasingly complex primate(More)
Studies of psychiatric disorders have traditionally focused on emotional symptoms such as depression, anxiety and hallucinations. However, poorly controlled cognitive deficits are equally prominent and severely compromise quality of life, including social and professional integration. Consequently, intensive efforts are being made to characterize the(More)
BACKGROUND Research into mental state attribution has repeatedly shown that patients with schizophrenia are impaired in their capacity to reflect upon their own and others' beliefs, knowledge and intentions, with important confounds being executive functioning, intelligence, duration of illness, and medication. Furthermore, the extent to which impaired(More)
The term "theory of mind" (ToM) describes an evolved psychological mechanism that is necessary to represent intentions and expectations in social interaction. It is thus involved in determining the proclivity of others to cooperate or defect. While in cooperative settings between two parties the intentions and expectations of the protagonists match, they(More)
Several studies have shown that patients with schizophrenia underactivate brain regions involved in theory of mind relative to controls during functional brain imaging. However, in most studies the samples were fairly heterogeneous in terms of clinical symptomatology. We examined a group of nine patients with first episode or recurrent episodes, who(More)
Many captive great apes show gross behavioral abnormalities such as stereotypies, self-mutilation, inappropriate aggression, fear or withdrawal, which impede attempts to integrate these animals in existing or new social groups. These abnormal behaviors resemble symptoms associated with psychiatric disorders in humans such as depression, anxiety disorders,(More)
Neuroimaging studies have revealed gray matter abnormalities in schizophrenia in various regions of the brain. It is, however, still unclear whether such abnormalities are already present in individuals at ultra-high risk (UHR) for transition into psychosis. We investigated this issue using voxel-based morphometry of structural magnetic resonance images(More)
