Age and the relationship to field independence, as measured by the Embedded Figures Test (EFT), among a sample of 160 creative women was studied. Comparisons were made between the mean EFT scores of creatine women and the mean scores of a sample of women not selected for creativity and the mean scores of two samples of men. Creative women were show...

Segments of resting heart rate were submitted to spectral analysis in order to assess changes in spectral power with age. Different frequencies of heart rate variability have been related to vagal and sympathetic cardiac control. Data were from 56 male volunteers ranging in age between 18 and 65 years of age. Spectral results revealed that respirat...

Mature (6 mo.) and aged (26 mo.) rats were trained on a DRL 6-sec schedule. In order to produce equivalent levels of task performance, the mature rats were trained for 16 sessions while the aged rats were trained for 20 sessions. After a 21-day interval, rats were tested for retention of the DRL task. No age-related differences in LTM of the DRL ta...

Two experiments were conducted. The purpose of the first experiment was to determine whether memory deficits for movement occur with age. The 52 subjects for Experiment 1 were placed in four age groups: 18-32; 33-47; 48-62; and 63-77. Tests were administered to determine each subject's ability to encode and recall as many as 12 consecutive linear m...

Social functioning is an important variable in the rehabilitation of stroke patients. We have designed a 28 item semi-structured interview to measure social functioning and have used this instrument in 103 stroke patients in whom we were investigating the occurrence of mood disorders. The social functioning exam was demonstrated to have high interr...

Descendants of rats possessing lower responsiveness to the removal of the parathyroid gland [4] were examined for the aging process of the hypothalamic-pituitary-ovarian axis. The first generation rats of these descendants were born to mothers parathyroidectomized (Px) on the fifth day of gestation and subsequent generation rats were developed by b...

Young adults and elderly adults received a series of topics for discussion, followed by a recall test of the topics per se and a recognition memory test of the questions asked during the conversations. Half of the participants in each age group were forewarned of the subsequent recall test (intentional memory); the remaining participants were not f...

The intent of this study was to assess the influence of sex-role appropriate materials on the utilization of logical competence among older persons, and to determine how such materials interact with subject's sex-role identity to affect cognitive performance. Thirty male and 30 female Ss (mean age = 71.3 years) were administered the Short Form of t...
