The authors hypothesized that at-risk individuals identified on the basis of their Chapman scale scores would be diagnosed with schizophrenia-spectrum disorders at follow-up. In the present study, the authors interviewed 135 young adults approximately 5 years following their initial assessment. The at-risk groups included high scorers on the Perceptual(More)
Individuals who scored high on Perceptual Aberration-Magical Ideation Scales (Per-Mag; n = 90), the Social Anhedonia Scale (SocAnh; n = 39), and control participants (n = 89) were administered saccadic refixation (prosaccade) and saccadic suppression (antisaccade) tasks. Eye movements were scored in terms of error rates and latency. None of the groups(More)
Sustained attention deficits have been posited as a potential endophenotypic marker of vulnerability to schizophrenia. Prior studies have indicated that schizophrenia patients, their first-degree relatives, and psychosis-prone individuals, identified on the basis of measures of positive schizotypy, have demonstrated sustained attention deficits. To date,(More)
This review focuses on saccade research with adult psychiatric patients. It begins with an introduction of the various types of saccades and the tasks used to evoke them. The functional significance of the different types of eye movements is briefly discussed. Research findings regarding the saccadic performance of different adult psychiatric patient(More)
BACKGROUND Identifying endophenotypes of schizophrenia will assist in the identification of individuals who are at heightened risk for the disorder. Investigators have proposed antisaccade task deficits as an endophenotypic marker of schizophrenia. However, the diagnostic specificity and the temporal stability of the task deficit are unresolved issues. To(More)
The domain-specificity of working memory was examined in psychosis-prone individuals with elevated social anhedonia scores. A group of individuals with deviant scores on the revised Social Anhedonia Scale (n=43) were compared with a normal control group (n=39) on delayed match-to-sample tasks involving spatial, identity, and affective information. The(More)
Although attentional deficits are frequently displayed by schizophrenia and spectrum patients, the precise nature of the impairment is unclear. The present study investigates attentional performance in 26 schizophrenia-spectrum outpatients and 24 healthy controls using the Attentional Network Task (ANT). We assessed the efficiency of the segregated(More)
The present study investigates executive functioning in schizotypic college students and control subjects using the Wisconsin Card Sorting Test (WCST). Inhibitory control and working memory, two aspects of executive functioning, were examined in deviantly high scorers on the Perceptual Aberration and Magical Ideation Scales (n=97), high scorers on the(More)
The present study examined spatial working memory and Wisconsin Card Sorting Test (WCST) performance in psychosis-prone individuals, either those with extremely high scores on the Social Anhedonia Scale (SocAnh; n = 49) or deviant scores on the Perceptual Aberration-Magical Ideation Scales (Per-Mag; n = 66). Sixty-three individuals with normal scores on the(More)
The nature of the affective deficit that characterizes social anhedonia is not well understood. Emotionally evocative visual stimuli were presented to undergraduates identified as anhedonic or normal, based on their scores on the revised Social Anhedonia Scale. The affective stimuli were chosen to elicit positive and negative emotion; a subset of slides(More)
