Schizotypy and facial emotion processing

The ability to accurately interpret facial emotion is crucial to social being and our capacity to correctly interpret threat-related expressions has obvious adaptive value. Healthy individuals appear

Threat perception in schizophrenia-spectrum disorders

Overall danger attributed to situations was greater for the clinical group than for the control group, which is consistent with other evidence showing that there may be a disconnect between the usual processes used to make inferences regarding potential threat in schizophrenia spectrum disorders.

New Findings for Face Processing Deficits in the Mental Disorder of Schizophrenia

Human faces may be one of the most familiar visual stimuli, and the most important stimulus for human social life. The highly evolved human ability to recognize faces represents an important

An intact threat superiority effect for nonsocial but not social stimuli in schizophrenia.

The discrepant performance across nonsocial and social threat detection tasks within the patient group is consistent with evidence indicating that social and nonsocial information processing can be differentially affected in schizophrenia.

Neural response to specific components of fearful faces in healthy and schizophrenic adults




Investigation of the neural correlates of threat perception in paranoid schizophrenia: An FMRI study

Impaired Recognition of Social Emotions following Amygdala Damage

The findings suggest that the human amygdala is relatively specialized to process stimuli with complex social significance, and provides further support for the idea that some of the impairments in social cognition seen in patients with autism may result from dysfunction of the amygdala.

A differential neural response to threatening and non-threatening negative facial expressions in paranoid and non-paranoid schizophrenics

Perception of threat in schizophrenics with persecutory delusions: an investigation using visual scan paths

The findings suggest abnormal information gathering and evaluation in schizophrenics, specifically related to the presence of persecutory delusions, and point to biased processing of contextual information in an ambiguous setting in these patients.

The human amygdala in social judgment

This investigation into the hypothesis that the human amygdala is required for accurate social judgments of other individuals on the basis of their facial appearance finds three subjects with complete bilateral amygdala damage to judge faces of unfamiliar people with respect to two attributes important in real-life social encounters: approachability and trustworthiness.

Cognitive neuropsychiatric models of persecutory delusions.

The major cognitive theories of persecutory delusion formation and maintenance are critically examined and the interaction of these cognitive processes, cross-sectionally and longitudinally, at cognitive psychological, neural network, and functional neuroanatomical levels are warranted to establish a comprehensive cognitive neuropsychiatric model of the persecutory delusions.

Imaging attentional and attributional bias: an fMRI approach to the paranoid delusion

The neural response particularly associated with attention to threatening material relevant to self and with the ‘self-serving’ attributional bias is investigated, providing a simple model for paranoid delusion formation that can be tested in patients.

Face processing impairments after amygdalotomy.

The presence of impairments affecting the learning of new faces and the comprehension of gaze direction and facial expressions of emotion is consistent with the hypothesis of a role for the amygdala in learning and social behaviour.
