Two experiments on the short-term free recall of 12-word associated and non-associated lists are reported. Degree of association (derived from norms obtained by continuous controlled association) and word frequency were varied. Significant facilitation as a result of the associative manipulations was obtained and clustering of the responses was positively related to this. Clustering was also affected by the method of presentation of the associated words; this occurred more often when they were grouped in presentation than when they were presented randomly arranged among other words in the list. Low frequency associated word lists were generally found to be more efficiently recalled than those of comparable association values but consisting of high frequency words. 相似文献

Signal probability is an important influence on vigilance. Typically, higher signal probability is associated with higher hit rate, lower response criterion, and lower response:signal ratio. However, signal probability effects on demanding, high-workload vigilance tasks have not been investigated. It is believed that attentional resources become depleted during performance of such tasks, leading to perceptual sensitivity decrements. Forty subjects performed high- (.35) and low- (.10) probability versions of a demanding vigilance task. Results differed in two important respects from those previously obtained with less demanding tasks. First, the decrement in perceptual sensitivity over time was greater for the high-probability task. Second, there were no effects of signal probability on response criterion. Subjective workload was higher for the high-probability task. Implications of the data for resource-depletion and expectancy theories of vigilance are discussed. 相似文献

The spatial cognitive map theory of O’Keefe and Nadel (1978) predicts that lesions of the hippocampal system should impair learning on spatial tasks but not learning on nonspatial tasks. However, there is evidence that such lesions can facilitate learning on certain nonspatial tasks. Their theory does not predict such facilitation. Nevertheless, it is reasonable to expect that animals possessing a spatial cognitive map would have an inherent bias to engage a mapping strategy and thus be at a disadvantage on certain nonspatial tasks in comparison with animals without the mapping capacity and bias. In the present study, fimbria/fornix lesions impaired learning on a spatial task, but actually facilitated learning on a nonspatial task of equal difficulty. Thus, brain lesions that interfere with map functioning can facilitate learning on tasks for which a mapping strategy interferes with task solution. The results require a modification of the spatial cognitive map theory. 相似文献

Neither acculturation nor gender were found to significantly relate to Asian-American willingness to see a counselor for either a personal or an academic problem. Participants were more willing to see a counselor for an academic problem than for a personal problem. 相似文献

Dispositional optimism and recovery from coronary artery bypass surgery: the beneficial effects on physical and psychological well-being 总被引:17,自引:0,他引:17

The effect of dispositional optimism on recovery from coronary artery bypass surgery was examined in a group of 51 middle-aged men. Patients provided information at three points in time--(a) on the day before surgery, (b) 6-8 days postoperatively, and (c) 6 months postoperatively. Information was obtained relating to the patient's rate of physical recovery, mood, and postsurgical quality of life. Information was also gathered regarding the manner in which the patients attempted to cope with the stress of the surgery and its aftermath. As expected, dispositional optimism proved to be an important predictor of coping efforts and of surgical outcomes. More specifically, dispositional optimism (as assessed prior to surgery) correlated positively with manifestations of problem-focused coping and negatively with the use of denial. Dispositional optimism was also associated with a faster rate of physical recovery during the period of hospitalization and with a faster rate of return to normal life activities subsequent to discharge. Finally, there was a strong positive association between level of optimism and postsurgical quality of life at 6 months. 相似文献

Familial environment associated with type A behaviors and psychophysiological responses to stress in children 总被引:1,自引:0,他引:1
This study tested two major hypotheses regarding the characteristics of family environments associated with children's Type A behaviors, anger frequency and expression, hostile outlook, hostility displayed during an interview, and cardiovascular responses to laboratory stressors. Two measures of family environment, Positive Affiliation and Authoritarianism, were derived by a factor analysis of the Family Environment Scale completed by parents. The sample consisted of 66 girls and 48 boys enrolled in Grades 2 through 12 from 114 families residing in a predominantly White, upper-middle-class suburb of Pittsburgh. Analyses largely supported the first hypothesis--that a less supportive and positively involved family climate would be associated with attributes of potential coronary heart disease (CHD) risk in children. Families scoring low on Positive Affiliation had children who were assessed as more angry and hostile on the basis of questionnaires and interview. Boys from these families had a more pronounced heart rate response to all laboratory stressors. The second hypothesis--that authoritarianism, in the absence of positive involvement and supportiveness in the family, would be associated with attributes of potential CHD risk in children--received support in regard to boys' heart rate responses to the serial-subtraction and mirror-image-tracing tasks. High Authoritarianism scores in combination with low Positive Affiliation scores in families predicted a heightened heart rate response in boys. Sex differences in the pattern of associations among family and child characteristics were also found. Results suggest that factors in the family environment may be important influences in children's development of characteristics that may, in adulthood, place them at risk for CHD. 相似文献
