OBJECTIVE The authors evaluated the neuropsychological correlates of temporal lobe abnormalities in schizophrenic patients. METHOD Fifteen schizophrenic patients underwent assessment of memory, by the Wechsler Memory Scale--Revised, and abstraction/categorization, by the similarities subtest of the Wechsler Adult Intelligence Scale--Revised and the(More)
OBJECTIVE Schizophrenia has long been thought to be characterized by a fundamental disturbance in semantic associations, which has often been presumed to be of neurobiological origin. The authors examined the neurophysiological characteristics of semantic processing in schizophrenic patients. METHOD During EEG recording, 15 schizophrenic patients and 15(More)
BACKGROUND Disturbances in both attention and language are central to the phenomenology of the schizophrenia spectrum disorders. The purpose of this study was to investigate the relative contributions of two factors, family status and schizotypy, on electrophysiologic measures of attention and semantic processing in family members of individuals with(More)
In an open trial design, adults (n=20) with posttraumatic stress disorder (PTSD) and either schizophrenia or schizoaffective disorder were treated via an 11-week cognitive-behavioral intervention for PTSD that consisted of education, anxiety management therapy, social skills training, and exposure therapy, provided at community mental health centers.(More)
Theoretical and clinical characterizations of attention in PTSD acknowledge the possibility for both hypervigilance and avoidance of trauma-relevant stimuli. This study used eye tracking technology to investigate visual orientation and attention to traumatic and neutral stimuli in nineteen veterans of the Iraq war. Veterans saw slides in which half the(More)
OBJECTIVE University and college health and counseling centers frequently warn female students about the red zone-a period early in a student's first year at college during which she may be at higher risk for unwanted sexual experiences (UWS). The authors designed this study to assess temporal risk for UWS in 1st- and 2nd-year college women. PARTICIPANTS(More)
Hypervigilance toward ambiguous or threatening stimuli is a prominent feature in many trauma survivors including active and returning soldiers. This study set out to investigate the factors that contribute to hypervigilance in a mixed sample. One hundred forty-five individuals, 50 of whom were war zone veterans, filled out a series of questionnaires(More)
BACKGROUND The latency of the P300 event-related potential is prolonged in disorders associated with neural damage and degeneration and also becomes prolonged in the course of neural changes that accompany aging. We tested whether the rate of P300 latency increase with age was greater in male schizophrenic patients than in normal subjects because a steeper(More)
Studies imposing rigorous control over lifetime alcohol intake have usually not found smaller hippocampal volumes in persons with posttraumatic stress disorder. Because the majority of negative studies have used adolescent samples, it has been suggested that chronicity is a necessary condition for such findings. To test the hypothesis that a smaller(More)
The modified Stroop effect (MSE), in which participants show delayed colour naming to trauma-specific words, is one of the most widely cited findings in the literature pertaining to cognitive bias in posttraumatic stress disorder (PTSD). The current study used a novel approach (Dissertation Abstract Review; DAR) to review the presence of the MSE in(More)
