Action and object naming in schizophrenia.

Patients with schizophrenia demonstrate impaired action verbal fluency, but no study has examined verb-noun differences using picture naming. The present study compared object and action naming in 20 adult patients diagnosed with schizophrenia (DSM-IV-TR, Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Text Revision; American Psychiatric Association, 2000) criteria, and 20 demographically matched healthy controls, using pictures. Overall, schizophrenic patients showed poorer naming than controls on all measures of object and action lexical semantic access and retrieval despite normal comprehension for action and object names.

Benton Visual Retention Test performance in normal adults and acute stroke patients: demographic considerations, discriminant validity, and test-retest reliability.

We examined relationships between demographic variables and Benton Visual Retention Test performance in 352 healthy Greek adults, aged 18-84 years. We derived norms for BVRT total number correct and error scores adjusted for variables that contributed significantly to the variance. We also investigated BVRT performance in 28 acute stroke patients M = 6.

Ruff 2 and 7 Selective Attention Test: normative data, discriminant validity and test-retest reliability in Greek adults.

Rapidly expanding interest in neuropsychological assessment in Greece has made the development of appropriate culture-specific normative data for core neuropsychological measures essential. In the present study, we sought to establish normative, test-retest reliability and discriminant validity data for the Ruff 2 and 7 Selective Attention Test in the Greek adult population. We administered the test using standard procedures to 218 healthy Greek adults (95 men), aged 17-80 years and two adult patient groups (26 detoxified opiate addicts and 23 HIV seropositive individuals).
