Four more-liked boys and four less-liked boys (M age = 58.13 months) were videotaped as they interacted separately in semi-structured activities with their own mother and father, the mother and father of a more-liked boy, and the mother and father of a less-liked boy. Parents of less-liked boys had more intensive interactions that were more controlling, directive, and intrusive than parents of more-liked boys. Parents of more-liked boys had extensive interactive patterns that made them better able to extend praise and encouragement to children not their own. Similarly, more-liked children seemed more sensitive than less-liked children to situational factors that occurred during interactions with parents not their own and were therefore better able to adjust their behavior to the expectations of the situation.  相似文献

Widespread Internet use has revolutionized health information and patient education for persons with chronic illnesses. The authors surveyed 147 HIV-positive persons to examine factors associated with Internet use and associations between Internet use and health. Information, motivation, and behavioral skills associated with using the Internet were related to Internet use. The authors found that health-related Internet use was associated with HIV disease knowledge, active coping, information seeking coping, and social support among persons who were using the Internet. These preliminary findings suggest an association between using the Internet for health-related information and health benefits among people living with HIV/AIDS, supporting the development of interventions to close the digital divide in HIV/AIDS care.  相似文献

Visual similarity effects in immediate verbal serial recall   总被引:4,自引:0,他引:4  
The role of visual working memory in temporary serial retention of verbal information was examined in four experiments on immediate serial recall of words that varied in visual similarity and letters that varied in the visual consistency between upper and lower case. Experiments 1 and 2 involved words that were either visually similar (e.g. fly, cry, dry; hew, new, few ) or were visually distinct (e.g. guy, sigh, lie; who, blue, ewe ). Experiments 3 and 4 involved serial recall of both letter and case from sequences of letters chosen such that the upper- and lower-case versions were visually similar, for example Kk, Cc, Zz, Ww , or were visually dissimilar, for example Dd, Hh, Rr, Qq . Hence in the latter set, case informationwas encoded interms of both the shape and the size of the letters. With both words and letters, the visually similar items resulted in poorer recall both with and without concurrent articulatory suppression. This visual similarity effect was robust and was replicated across the four experiments. The effect was not restricted to any particular serial position and was particularly salient in the recall of letter case. These data suggest the presence of a visual code for retention of visually presented verbal sequences in addition to a phonological code, and they are consistent with the use of a visual temporary memory, or visual "cache", in verbal serial recall tasks.  相似文献

Two studies examined the effect of two comparison processes on perceptions of fairness and satisfaction. Rewards relative to others (social comparison) and relative to expectancies (expectancy comparison) were orthogonally varied while absolute level of reward was held constant. Both studies showed, contrary to previous theory, that only social comparisons are related to perceived fairness, yet both comparisons are significantly related to satisfaction in an additive manner. Social comparisons explained more variation in satisfaction and dominated responses to more specific measures of affect. Partial support for specific predictions derived from equity theory and expectancy theory are reported. The overall results are interpreted as demonstrating the importance of the salience of frames of reference in reward evaluation.Estabilished practices create expectations, and since men have traditionally received greater rewards than women for the same services, they expect disproportionate rewards and tend to be disappointed if they do not get them. But these expectations have nothing to do with investments, and neither are they rooted in a conception of justice. (Blau, 1964, p. 195)  相似文献

The activation of motivational systems by stimuli in the environment that are associated with rewarding experiences is able to trigger plastic changes in the brain, thereby altering the attentional priority of those stimuli. As a result, attentional deployment is often abnormal in addiction, with drug-related stimuli attracting attention automatically and gaining control over behavior. For example, smokers show attentional biases toward smoke-related cues, but the mechanisms underlying these effects and the nature of their link to addiction are still debated. Here, we investigated the influence of gender and individual factors on the temporal dynamics of attentional deployment toward smoke-related stimuli in young smokers. Crucially, we found a striking gender difference, with only males exhibiting a typical attentional bias for smoke-related items, and the bias revealed strong time dependency. Additionally, for both males and females, various personality traits and smoking habits predicted the direction and strength of the measured bias. Overall, these results unveil a crucial influence of several predictors—notably, gender—on the biases of attention toward smoke-related items in chronic smokers.  相似文献

ABSTRACT— Efficient goal-directed behavior in a crowded world is crucially mediated by visual selective attention (VSA), which regulates deployment of cognitive resources toward selected, behaviorally relevant visual objects. Acting as a filter on perceptual representations, VSA allows preferential processing of relevant objects and concurrently inhibits traces of irrelevant items, thus preventing harmful distraction. Recent evidence showed that monetary rewards for performance on VSA tasks strongly affect immediately subsequent deployment of attention; a typical aftereffect of VSA (negative priming) was found only following highly rewarded selections. Here we report a much more striking demonstration that the controlled delivery of monetary rewards also affects attentional processing several days later. Thus, the propensity to select or to ignore specific visual objects appears to be strongly biased by the more or less rewarding consequences of past attentional encounters with the same objects.  相似文献
