Abstract

This paper examines the relationship between quantitative and qualitative indicators of social support and anxiety. depression and use of health services in a sample of 37 wives of myocardial infarction (MI) patients. In a prospective design, the wives were interviewed during the acute phase of the illness, three months and 10 years post index-MI. Congruent with previous research, the quantitative aspect of social support, defined as number of persons giving help, was unrelated to adjustment, whereas qualitative aspect of social support, defined as the wives' dissatisfaction with social support, was associated with depression and use of health services. The observed association indicated, however, an effect in the opposite direction of the social support model. The findings were unexpected and may be due to a small sample. An alternative explanation is that long-term relationship between depression and social support is more complex, and more long-term studies are needed in this field.  相似文献

Memory impairment following closed-head injury (CHI) in children is well documented. Characterization of the memory deficits of children with CHI could contribute to the prediction of academic performance and rehabilitation of these children. Twenty-five children who sustained closed-head injury and 25 matched controls were administered the Rey Auditory Verbal Learning Test (AVLT). The advantage of this memory test is that a number of memory components are measured simultaneously, thus enabling us to study the relations between different aspects of memory within the same patient sample. The findings indicate that the Rey AVLT is a good test for characterization of impaired verbal memory in children following CHI. Transformation of scores derived from the Rey AVLT to Z-scores enables us to determine the relative effect of CHI in children on different memory scores. Raw scores were more vulnerable than relational ones, derived as the difference between two raw scores (e.g., learning, Trial 5?1), to closed-head injury in children, and scores reflecting word span were the least vulnerable. The results are discussed in terms of the possible contribution of the frontal lobes, which are frequently affected in closed-head injuries, to memory performance.  相似文献

When trying to move in a straight line to a target, participants produce movement paths that are slightly (but systematically) curved. Is this because perceived space is curved, or because the direction to the target is systematically misjudged? We used a simple model to investigate whether continuous use of an incorrect judgement of the direction to the target could explain the curvature. The model predicted the asymmetries that were found experimentally when moving across a background of radiating lines (the Hering illusion). The magnitude of the curvature in participants' movements was correlated with their sensitivity to the illusion when judging a moving dot's path, but not with their sensitivity when judging the straightness of a line. We conclude that a misjudgement of direction causes participants to perceive a straight path of a moving dot as curved and to produce curved movement paths.  相似文献

We explored emotional accompaniments to stages of a musician's cycle of creativity through interviews with musicians. Creativity was defined in terms of performance or composition. These musicians described strong emotional vacillations that occur across the creative cycle and discussed ways of dealing with emotional issues involved in moving from one work to the next. Parallels were drawn between emotional aspects of completing a performance or composition to emotional aspects of termination in psychotherapy. Suggestions were offered to musicians for means of dealing with naturally occurring but powerful emotional components of creativity. In addition, some of the musicians suggested that music educators consider teaching students about potential emotional issues that may accompany creative effort. An integration of these issues into music education programs might better prepare students for careers as professional musicians.  相似文献

The objectives of the current study were (1) to assess adjustment in patients following a first myocardial infarction (MI) at 9 months compared with 4-6 weeks post-MI, (2) to examine the availability of and satisfaction with social support over time, and (3) to determine separate baseline psychosocial predictors of recurrent cardiac events. A questionnaire assessing post-traumatic stress disorder, anxiety, depression, health complaints, and social support, was distributed to consecutive patients 4-6 weeks and 9 months post-MI. Prior to assessment at follow-up, 8 (7%) of 112 patients had dropped out, and two had died due to cardiac causes. Objective clinical measures were obtained from medical records. There was an improvement in somatic and cognitive symptoms at follow-up, but no change in symptoms of arousal, depression, and anxiety. Half of the patients were afraid of a recurrent MI. There was a significant decrease in social support between baseline and follow-up, and lower social support at baseline was associated with a 10% increased risk of recurrent cardiac events at follow-up (OR: 0.90; 95% CI: 0.84 to 0.97) adjusting for all other variables. Some patients still experienced difficulties with psychosocial adjustment 9 months post-MI despite a reduction in somatic and cognitive symptoms. Social support decreased over time, which may have serious prognostic implications; lower social support at baseline was an independent predictor of recurrent events at 9 months. An important step for future research will be to investigate how social support can be enhanced in patients at risk.  相似文献

A decade ago, S. Aglioti, J. F. X. DeSouza, and M. A. Goodale (1995) published an experiment that has had a big influence on the way that visual information is thought to control human behavior. Their findings have often been simplified as suggesting that action is immune to perceptual illusions. The current authors critically analyze the 4 steps involved in this simplification and argue that research during the last 10 years has shown that the validity of 3 of the 4 steps is doubtful. They conclude that this experiment cannot be regarded as firm support for the 2-visual-systems hypothesis (i.e., that the ventral stream is for perception and the dorsal stream is for visually guided actions).  相似文献

The authors examined the relationship between personality and cognitive impairment in 4,039 members of the Swedish Twin Registry. Neuroticism and extraversion scores were collected in 1973 at midlife, and cognitive impairment was assessed in the same group 25 years later. Data were analyzed with case-control and co-twin control designs. Greater neuroticism was associated with higher risk of cognitive impairment in the results from case-control, but not from co-twin, analyses. Compared with both extraversion and introversion, moderate extraversion was associated with lower risk of cognitive impairment in both case-control and co-twin designs, as was the combination of high neuroticism and low extraversion. Findings are discussed in the context of theories related to personality, psychological distress, arousal, and cognitive function.  相似文献
