This study examined the effect of prior biofeedback-assisted training of hand warming or hand cooling on the subsequent ability to train the opposite response. A two-group crossover design employed 43 subjects with one group receiving three days of hand warming followed by three days of hand cooling, while the second group received the opposite sequence. Analysis indicated subjects were able to produce the appropriate changes in hand temperature and were more successful at hand cooling than hand warming. During the transfer of training phase, subjects with prior training in hand cooling were able to produce warming above baseline levels compared with subjects initially trained to hand warm. In contrast, prior training of hand warming had no effect on the subsequent ability to cool hands.  相似文献

Interview data were collected from 46 English elderly men (age 70 to 94 years) relating to attitudes, psychological traits, and life satisfaction. Sexual interest was not related to life satisfaction or marital status but was significantly correlated with measures of emotional expressivity, personal identity, as well as regrets about the past. Findings are discussed in terms of Erikson's later stages of ego development.  相似文献

We investigated differences between mildly depressed subjects and normal controls in their memory for, and judgments of, another person. All subjects read a story (containing either predominately positive or predominately negative items) under instructions to form an impression of the story target. Subjects later made several judgments about the target and attempted to recall the story. For both the positive and the negative story, depressed subjects produced significantly more negative intrusions (i.e., recalled nonpresented negative items) than did the normal subjects, but they did not recall more negative items correctly than did the normal subjects. Depressed subjects also perceived themselves as more similar to the negative story target than did the normal controls and indicated greater liking for the negative story target than did the normal controls.  相似文献

Summary The relative functional significance of attention shifts and attentional zooming for the coding of stimulus position in spatial compatibility tasks is demonstrated by proposing and testing experimentally a tentative explanation of the absence of a Simon effect in Experiment 3 of Umiltà and Liotti (1987). It is assumed that the neutral point of the spatial frame of reference for coding spatial position is at the position where attention is focussed immediately before exposition of the stimulus pattern. If a stimulus pattern is exposed to the right or the left of this position a spatial compatibility effect can be observed when the stimulus-response pairing is incompatible. Generalizing from this, one can say that a spatial compatibility effect will be observed if the last step in attentional focussing of the stimulus attribute specifying the response is a horizontal or a vertical attention shift. If the last step in focussing is attentional zooming (change in the representational level attended to), the stimulus pattern is localized at the horizontal and the vertical positions where the last attention shift had positioned the focus. In this case the spatial code is neutral on these dimensions and so no spatial compatibility effect should result. To test this model we conducted two experiments. Experiment 1 replicated the finding of Umiltà and Liotti that there is no Simon effect in the condition with no delay between a positional cue (two small boxes on the left or right of a fixation cross) and the imperative stimulus, whereas in the condition with a delay of 500 ms a Simon effect was observed. In a comparison condition with a single, rather large cue instead of two small boxes (forcing attention to zoom in), no Simon effect was observed under either delay condition. Experiment 2 used a spatial compatibility task proper with the same experimental conditions as Experiment 1. But in contrast to those of Experiment 1, the results show strong compatibility effects in all cue and delay conditions. The absence of a Simon effect in some experimental conditions in Experiment 1 and the presence of a spatial compatibility effect proper in all conditions in Experiment 2 are consistently accounted for with the proposed attentional explanation of spatial coding and spatial compatibility effects.  相似文献

Data were obtained from 46 mother-child pairs from the Child Behavior Institute (CBI) at the University of Tennessee. These mother-child dyads were referred for psychological help because of the child’s aversive behavior. Child-parent interactions were quantified using a multi-code, observational system. Correlational and multiple regression analyses (stepwise) were conducted to find the best predictor of the child’s aversive behavior. Results showed that the child’s aversive behavior was significantly correlated with the mother’s aversive, indiscriminate, and compliance behaviors. The regression analysis showed mother’s aversive behavior to be the best predictor of the child’s aversive behavior. Moreover, our results seem to point out that the compliance hypothesis is more effective in predicting child aversive behavior than the predictability hypotheses. It appears that since the two hypotheses are dealing with similar processes, they are more complementary than oppositional. This study used data collected by the Child Behavior Institute (CBI) at the University of Tennessee, Knoxville. The authors are indebted to Robert Wahler, Michael Smith, and Sue Dunn for their helpful comments on this paper.  相似文献

This experiment examined the processing of information from multiple element visual displays, using techniques derived from the theory of signal detectability. The method allows one to specify how observers integrate information from individual elements of a display. The experiment tested numerical and graphical displays having different display sizes, durations, and arrangements of elements. Observer performance increased with the number, m, of display elements, but at less than the ideal √m rate. Observer performance was consistent with a model of information integration constrained by internal noise. Linear arrays of elements resulted in better performance than did square arrays. Graphically coded elements resulted in better performance than did numerical elements. Observer decision weighting of element information from graphical displays was approximately uniform across spatial position, but the weighting of information from numerical displays was concentrated on elements near the fixation point.  相似文献

A longitudinal organizational field study examined work satisfaction and employee growth coping as joint predictors of turnover. Three employee categories were examined: 1) No Turnover, 2) turnover within the same occupational field (Intraoccupational Turnover), and 3) turnover to a new occupational field (Interoccupational Turnover). Work satisfaction was moderate in the first two groups and low in the third group. As predicted, a specific strategy of employee coping, growth, was lowest in the first group, moderate in the second group, and highest in the third group. Through the use of linear discriminant analysis, 66.4% of the employees were correctly classified into No Turnover, Intraoccupational Turnover, and Interoccupational Turnover groups based only on information regarding work satisfaction and growth coping. The first squared canonical correlation was found to equal .30, far surpassing the modest work satisfaction/turnover correlations found in all previous studies.The authors wish to thank the two anonymous reviewers for their thoughtful comments.  相似文献
