Absolute auditory threshold and threshold of unpleasantness of chronic schizophrenic patients and normal controls.
The method of average error was modified tor research in schizophrenia and was used in establishing both the absolute auditory threshold and the threshold of unpleasantness. The results showed chronic schizophrenic patients had a higher absolute threshold but a lower threshold for when a tone became unpleasantly loud. The results add evidence that chronic schizophrenic patients find external st...
متن کاملNo differences in visual theory of mind abilities between euthymic bipolar patients and healthy controls
BACKGROUND Research on theory of mind (ToM) abilities in patients with bipolar disorder has yielded conflicting results. Meta-analyses point to a stable moderate impairment in remitted patients, but factors such as subsyndromal symptoms, illness severity, and deficits in basic neurocognitive functions might act as confounders. Also, differences in deficits depending on task area (cognitive or a...

متن کاملDifferences between two studies of hand preference in psychiatric patients.
Significant differences in handedness patterns between groups of psychiatric patients and normal controls were identified in two recent British studies, with substantial disagreement in some important findings. Most of the discrepancies were attributable to the different application of a simple classification of handedness data, and the remainder to differences in sample size. Diagnosis, sex an...
متن کاملSchizotypal Traits among Patients with Schizophrenia, Their Non-Psychotic First-Degree Relatives, and Normal Controls
Evidence has suggested that risk for schizophrenia is likely to occur in non-psychotic first-degree relatives of patients with schizophrenia. On the other hand, schizotypal personality disorder is genetically related to schizophrenia. The aim of this study was to compare schizotypal traits (i.e., positive schizotypy, negative schizotypy, cognitive disorganization, and impulsive nonconformity) a...
