objective: the present study aimed to clarify dissociative symptoms in patients with schizophrenia and its association with negative and positive symptom of schizophrenia. methods: based on the 4th edition of diagnostic and statistical manual of mental disorders (dsm-iv) criteria, 80 schizophrenic subjects were randomly selected from patients who referred to the clinics of psychiatry hospital i...

in schizophrenia, neurocognitive functions are one to two standard deviations below the normal controls and these deficits have a significant relationship with overall functioning and poor outcome. according to this fact, it is important to investigate the factors that effect neurocognition in schizophrenic patients. this study was carried out to demonstrate the relationship between attention/v...

OBJECTIVES (1) To test the hypothesis that minor physical anomalies are increased in patients with schizophrenia and (2) to investigate differences in the prevalence of minor physical anomalies in patients with familial and sporadic schizophrenia and their first degree relatives. METHODS A weighted Waldrop assessment was carried out on 214 subjects in five groups: schizophrenic patients from ...

OBJECTIVE The aim of this study was to examine reality testing in schizophrenic children and compare it with normal children using minus responses subcomponent in ego impairment index of the Rorschach test. METHODS In a descriptive design, 20 accidentally sampled children, including 10 schizophrenic and 10 normal children, were recruited in to two groups and were compared in terms of reality ...

Clinical experiences indicate that schizophrenic cognitive disturbances may be partly due to the unsuccessful construction of their cognitive context. In this article, two experiments are introduced in which schizophrenic deficits in utilization of information for construction of effective cognitive context were examined through measurements of event-related potentials, particularly P300s. In a...

Due to the deficits of schizophrenic patients regarding the understanding of vague meanings (D. Ketteler and S. Ketteler (2010)) we develop a special test battery called HOLF (high order linguistic function test), which should be able to detect subtle linguistic performance deficits in schizophrenic patients. HOLF was presented to 40 schizophrenic patients and controls, focussing on linguistic ...

Life-time criminality, family history, and situational factors during a fire-setting offense were compared between 44 fire setters who had been diagnosed with schizophrenia or delusional psychosis and 260 nonpsychotic fire setters who had undergone a pretrial forensic psychiatric evaluation. The same comparisons were made between alcoholic (n = 25) and nonalcoholic (n = 19) schizophrenic fire s...

Previous research suggests, though by no means consistently, that schizophrenic patients may be less able than normals to predict the speech of other people, and that schizophrenic speech is less predictable than normal speech. The present experiment tests these two suggestions and also a third possibility, that the difference between schizophrenic and normal speech is less marked for schizophr...

Previous studies showing that schizophrenic patients have a deficit in the ability to perceive facial expressions of emotion in others often have not used a differential deficit design and standardized measures of emotion perception. Using standardized and cross-validated measures in a differential deficit design, S. L. Kerr and J. M. Neale (1993) found no evidence for a deficit specific to emo...

The purpose of this study was to investigate the neurofunctional substrate of verbal learning and memory impairments in schizophrenic patients. In this pilot study, our aim was to compare the memory disturbance of schizophrenic patients to the subcortico-frontal memory profile of Parkinson's disease (PD) patients. The California Verbal Learning Test, a verbal episodic memory test, was administe...
