Cognitive impairments in depression have recently been proposed as secondary to more basic attentional disturbances. Studies have shown that performance on the Stroop Color-Word Test is impaired in depressives, but it is not clear whether this impairment reflects a primary distractor inhibition disturbance or a more global cognitive dysfunction, such as a(More)
Stroop stimuli were used to measure the negative priming effect in eight positive and 10 negative schizophrenics, 21 depressive and 35 healthy control subjects in order to test hypotheses of insufficient versus persistent cognitive inhibition in schizophrenia. Data show that schizophrenics do not increase their response times to suppressor Stroop items(More)
The Stroop Word-Color Test was used to study selective attention deficits in schizophrenic and nonschizophrenic psychiatric patients, compared with nonpsychiatric control subjects. Parts of the Weschler Memory Test and a shortened version of the Stroop Test were administered to test the hypotheses that the attentional deficit could be explained by problems(More)
OBJECTIVE To identify neuropsychological domains, including fine motor dexterity, that are related to social functioning in schizophrenia. METHOD Thirty-six DSM-IV schizophrenic subjects were assessed using the Purdue Pegboard test, the Modified Wisconsin Card Sorting test, the Tower of London, Schwartz' Reaction Time and Wechsler's Associate Learning and(More)
Disruptive vocalizations (DVs) constitute a serious problem in geriatric nursing homes. The current literature suggests that DV can be interpreted as a way for demented persons with language limitations to communicate with others. In an attempt to test this hypothesis, 59 participants were recruited from six nursing homes to form two groups: one group of(More)
OBJECTIVE This is the first study to report a direct comparison of neuropsychological performance in Kraepelinian vs. non-Kraepelinian schizophrenia (SZ). METHODS 17 Kraepelinian and 19 non-Kraepelinian subjects were assessed on a neuropsychological battery including the Purdue Pegboard, Schwartz' Reaction Time task, the Modified Card Sorting Test, the(More)
BACKGROUND The objectives of the study were to characterize and compare the cognitive profile and natural evolution of patients presenting late-onset psychotic symptoms (LOPS: onset ≥ 50 years old) to those of elderly patients (≥ 50 years old) with life-long/early-onset schizophrenia (EOS: onset <40 years old). METHODS Neuropsychological profiles of 15(More)
Relationships between clinical retardation (measured by the Hamilton Depression Inventory) and selective attention (measured with a computerized version of the Stroop word colour test) were studied in a population of 21 depressed patients. Stroop interference was higher in depressed patients than in normals. Desynchronized presentations of the distractor(More)

INTRODUCTION Memory deficits in patients with schizophrenia (SZ) are considered as a key feature of the clinical manifestations of the disease. In order to further examine the role and nature of memory deficits in SZ, the pattern of errors in verbal and spatial serial recall tasks committed by SZ patients was compared to that of healthy controls. We also(More)
