In a study of air traffic controllers, religious differences are found in the way Type A behavior is associated with several health status indicators. Associations between the Jenkins Activity Survey (JAS) and physical illness incidence, health-promotive behavior, diastolic and systolic blood pressure, subjective distress and impulse control problems, and alcohol consumption are examined by religious attendance, religious affiliation, and change in affiliation. Findings confirm that Type A does not vary significantly by religion. However, there are several significant findings between Type A and various health indicators. Type A is associated with illness incidence, overall and more strongly in several religion, subgroups. Type A and alcohol consumption are related positively in Protestants and converts, and negatively in churchgoing Catholics. Type A is related to impulse control problems in churchgoing Protestants and to subjective distress in churchgoing Catholics. Finally, in individuals with weak or no religious ties, Type A is associated with lower blood pressure. This last finding suggests that in some people (for example, the irreligious or unchurched), the coronary-prone behavior pattern may have cardiovascular effects which are salutary in at least one respect.The authors wish to thank Dr. Kyriakos S. Markides and Laura A. Ray for their assistance with this study. Address requests for reprints to Dr. Levin at the Institute of Gerontology, 300 North Ingalls, Ann Arbor, MI 48109.  相似文献

32 children 5 to 6 yr. old, 32 9 to 11 yr. old, and 32 adults linked musical fragments to emotions in a similar manner, older subjects being more accurate. Some emotions were more difficult than others; anger and fear were often confused. Older subjects gave better justifications for their choices.  相似文献

Visual cognitive differences between hearing (N = 16) and deaf (N = 32) high-school and middle-school students were studied. Visual tasks were presented on a microcomputer and response latencies were collected. Significant differences were noted between the deaf and normal groups but not between total communication deaf and oral deaf students. These differences support the hypothesis that deaf students prefer a visual cognitive strategy. Implications for educating the deaf are discussed.  相似文献

The Rosenberg Self-esteem Scale was administered to 550 14- and 16-yr.-old (+/- 6 mo.) girls. Self-esteem scores were categorized by weight and weight by height. Scores on the Quetelet Index for obesity were correlated with self-esteem scores. Mean self-esteem of the low- and middle-weight by height group was significantly higher than the mean of the high-weight by height group. In analyzing weight alone, the self-esteem of the middle-weight group was significantly higher than the self-esteem of the high-weight group. The correlation of the obesity index and self-esteem indicated that as weight increased self-esteem decreased.  相似文献

Observations on three children with neurolisteriosis (one case of meningitis, two cases of meningoencephalitis, each Serovar 4 b), show that even after the neonatal period, listeriosis must not be ignored in the process of diagnosis and therapy. It is the bacteriological examination of the cerebrospinal fluid, together with the blood culture, and not clinical symptoms and serology that guarantee a timely diagnosis and therapy (ampicillin and gentamicin).  相似文献

Insight reflects the unitary nature of psychic activity in contrast to the fragmentation created in abstracting categories for the purpose of study and discussion. The unique analytic clinical dyad offers a structure in which intrapsychic fragments can be actualized and integrated. As a result, the analyst's contribution is more crucially one of exploration than of revelation. Whatever the area of examination, past or present, the link to analytic immediacy offers the opportunity to make meanings meaningful, to convert known facts to psychic truths. The analyst's clinical task requires his private self-analysis as part of the collaborative exploration of how the patient's mind works. Higher level ego functioning, including acutely active remembering, is at times transiently loosened in order for the analyst to share in the clinical work of discovery. The words the analyst uses to communicate his understanding convey only approximate manifest meanings, though they structurally reveal deeper messages of importance to the patient. These verbal approximations help stimulate self-reflection in the analysand as a step in the process of gaining insight.  相似文献

A plate-pushing task was used to measure endogenous pain in the wrist from different loci. Practical application in rehabilitation seems reasonable.  相似文献
