No differences were seen in performance on either verbosequential or visuospatial neuropsychological tests among three groups of women. There were also no differences among the phases of the menstrual cycle on any of the tests. The design of this study was to sample performance of women on verbosequential and visuospatial neuropsychological tests during(More)
Follicle Stimulating Hormone (FSH) levels were negatively correlated with visuospatial function in two successive testing sessions in 32 young adult men. Men with high concentrations of FSH performed poorly on three-dimensional tests and tests of point localization. Men with low concentrations tended to perform better. Luteinizing Hormone (LH) tended to(More)
This study evaluated the performance of hearing-impaired adolescents on tests of specialized cognitive functioning and explored the linkage between cognitive profile and reading achievement. Other variables noted were mathematics achievement, speech production, etiology, and age of onset of hearing loss. Subjects were 62 severely-to-profoundly(More)
Right ear superiority was found for two groups of 24 subjects on a dichotic listening test of melodies each differing only in rhythm. In addition, no ear difference was found in the same two groups for a dichotic melodies test differing only in pitch or pitch pattern. Finally, the usual left ear superiority was seen for dichotic presentation of chords and(More)
It has long been believed that stress and drug abuse are related. Studies using animal models have repeatedly demonstrated that stressed animals more readily self-administer alcohol or other drugs. Similarly, human patients consistently report in clinical interviews that stress is one reason for taking drugs. There are also studies that document(More)
Increase of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in men by injection of luteinizing hormone releasing hormone (LHRH) prevented improvement in a spatial orientation test relative to a placebo condition. By contrast, performance on a fluency task was significantly increased after LHRH injection relative to the placebo condition.(More)
Patients with Parkinson's disease and patients with dementia showed greater deterioration on functions attributed to the right cerebral hemisphere, than on functions attributed to the left. Relative to matched controls, Parkinson patients were significantly impaired on right hemisphere tests, but did not differ on left hemisphere tests. Demented patients(More)
