BACKGROUND Social cognition is a complex phenomenon involving several distinct processes. Numerous studies have shown that individuals with schizophrenia are largely impaired on this domain of cognition. However, most have focused on a single aspect of social cognition, namely "theory of mind" and/or included patients with long standing illness. OBJECTIVE(More)
CONTEXT Memory is one of the cognitive functions most affected in schizophrenia, with deficits observed from the first episode of psychosis (FEP). Previous studies have indicated that some memory processes may be more affected than others. OBJECTIVE To examine the neural correlates of 3 specific memory processes in FEP by means of functional magnetic(More)
Previous positron emission tomography (PET) studies have shown greater medial temporal lobe activation (MTL) for associative memory encoding relative to deep item-oriented encoding. Greater MTL activation has also been reported for associative novelty detection. Although it has been suggested that these patterns of MTL activation could reflect the creation(More)
Beck and collaborators have proposed a distinction between clinical insight and cognitive insight and have developed a tool for the assessment of the latter, namely the Beck Cognitive Insight Scale (BCIS). The present study explored in 51 patients with a first episode of psychosis the neurocognitive correlates of cognitive insight as assessed with the BCIS.(More)
OBJECTIVE In psychotic disorders, impairments in cognition have been associated with both clinical and functional outcome, while deficits in social cognition have been associated with functional outcome. As an extension to a recent report on neurocognition and short-term clinical outcome in first-episode psychosis (FEP), the current study explored whether(More)
Several studies have demonstrated that patients with schizophrenia show impairments in social cognition and current evidence indicate that this deficit is associated with abnormal activity in specific brain regions. In addition to functional imaging studies, we believe that the identification of structural correlates of social cognitive processes may help(More)
