Using computer simulation, the authors assessed the accuracy of J. E. Hunter, F. L. Schmidt, and H. Le's (2006) procedure for correcting for indirect range restriction, the most common type of range restriction, in comparison with the conventional practice of applying the Thorndike Case II correction for direct range restriction. Hunter et al.'s procedure produced more accurate estimates of both the mean and standard deviation in meta-analysis than the conventional procedure. Even when its key assumption that the effect of selection on a 3rd variable is fully mediated by the independent variable was violated, Hunter et al.'s procedure was still relatively more accurate than the conventional procedure. When applied to data from a previously published meta-analysis, the new procedure yielded results that led to different substantive conclusions. 相似文献

Previous studies of attention-directing cues have focused largely on the effects of cuing on perceptual processes, but cuing may also influence the transfer of perceptual representations into visual working memory. In the present study, we examined this potential role of cues, using both predictive and non-predictive cues in the context of a visual working memory task. Each trial began with a cue, followed by an array of six colored squares, a delay interval, and then a probe square presented at th e location of one of the squares in the previous array. The subjects were required to indicate whether the color of the probe square was the same as the color of the square that had previously been presented at the same location. Performance on this working memory task was more accurate when the cued location was probed than when an uncued location was probed, even when the cued location was no more likely to be probed than any of the uncued locations. An additional experiment using the abrupt-onset paradigm of Yantis and Jonides (1984) yielded similar results. Thus, visual transients may automatically influence the transfer of perceptual representations into visual working memory. 相似文献

A picture of a nude isolated in a series of pictures of clothed models was quite memorable, but when compared with a clothed picture, the nude impaired memory for background picture derails as well as pictures immediately following the nude (anterograde amnesia). Recall of details given picture-gist recall, as well as recognition of person details, were equivalent in the clothed and nude conditions. A clothed picture isolated in a series of nudes did not hurt memory for background information, nor did it produce anterograde amnesia. Apparently, distinctiveness supports good memory for the gist of the nude or clothed pictures. However, distinctiveness is not responsible for the anterograde amnesia and poor memory for background details found with nudes. 相似文献

This paper looks at some of the processes that are at work in finding oneself in analysis. It explores Jung's unique contribution to our thinking about the self and its dynamic of individuation. The author attempts to show how the Self, in its quest for consciousness, requires the surrendering of ego inflation--the narcissistic delusion that the ego is the self. A case is made for seeing analysis as an individuation process which offers the opportunity for experiences of a more authentic sense of oneself. Jung stated that individuation requires the ego to enter into service of the Self. For this to happen, the author argues that both patient and analyst must be prepared to make sacrifices and take risks. Using clinical examples, he illustrates that, although purposive, the Self can be experienced as violent and destructive if the ego is unable to facilitate its expression. This may result in an individuation crisis for both analyst and patient. The paper demonstrates how impasse in analysis can evoke the transcendent function, which also requires sacrifices to be made and risks to be taken for analysis to proceed. 相似文献

This article reports progress in an ongoing research program examining older adults' decision-making competence (DMC). Using a theoretical framework that emphasizes the person-task fit in assessing DMC, the authors report the results of a study comparing older versus younger adults' decision performance on simple and complex tasks about health, finance, and nutrition. The authors hypothesized and found that increasing age and task complexity were related to greater comprehension errors and inconsistency in decision making. Hierarchical regression analyses showed that a large amount of age-related variance in performance on the decision tasks could be accounted for by exogenous social variables, health measures, basic cognitive skills, and attitudinal measures. The discussion emphasizes several directions for future research, including the need to validate the meaning of performance on these tasks for real-life decision processes. 相似文献

Evidence for a gene-environment interaction in predicting behavioral inhibition in middle childhood 总被引:8,自引:0,他引:8

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood. 相似文献

The present study investigated the role of various protective and vulnerability factors in the development of depressive symptoms. A sample of normal adolescents (N=373) completed the Children's Depression Inventory and measures of a negative attributional style, parental rearing behaviour, coping styles, and perceived self-efficacy. In addition to computing the correlations between depression and these protective and vulnerability factors, the present data were also subjected to structural equations modelling to examine the correlational structure of the data. Depression was accompanied by high levels of parental rejection, negative attributions, and passive coping, and by low levels of active coping and self-efficacy. Furthermore, a model in which negative parental rearing behaviour and a negative attributional style featured as the primary sources of depression, while coping styles and self-efficacy played a mediating role in the formation of depressive symptoms, provided a reasonable fit for the data. 相似文献

In formulating his theory of action control, Kuhl (1983) proposed two motivational states: action orientation and state orientation. People who are action oriented are able to ignore all informations in concrete situations which are irrelevant with regard to the preferred goals. Persons who are state oriented tend to focus sooner on the outlast aspects of a special state. Kuhl introduced a questionnaire HAKEMP to record these tendencies. Further on, there occurs the general assumption that in a particular state of state orientation, people have only a limited processing capacity for given tasks. This hypothesis was tested in an experiment (n = 88) with a stimulus-reaction task. The conditions were varied by the type of the task (fixed or variable stimulus interval) and feedback for the subjects' ability to react. It was expected that for the fixed stimulus interval condition, state-oriented people would be less efficient than action-oriented subjects; with feedback there should be increasing results. The experiment however, shows no significant difference between the performance of state- and action-oriented subjects. These results are discussed in relation to modifications of the HAKEMP questionnaire. 相似文献

The cerebrospinal fluid of 69 patients with tumors of the brain and the spine was examined for total protein content, IgG concentration, IgG total protein quotient, and electrophoretic protein pattern. There is no specific finding in the case of the central nervous system. At best characteristic constellations may be established. 相似文献
