Rats were exposed to the compound flavors AX and BX, presented in alternation, and to CX on a separate block of trials. Generalization to BX after aversion conditioning with AX was less than to CX. An equivalent effect was found when the nature of the common element was changed after preexposure but not when the common element was omitted during preexposure, during conditioning and test, or both. Rats conditioned with X alone again showed less aversion to BX than to CX; similarly, rats conditioned with a novel flavor (Y) showed less aversion to BY than to CY. These effects support the proposal that intermixed preexposure to AX and BX enhances the perceptual effectiveness of their unique features, A and B. 相似文献

This longitudinal study examined memory loss in a sample of 391 initially nondemented older adults. Analyses decomposed observed memory loss into decline associated with preclinical dementia, study attrition, terminal decline, and chronological age. Measuring memory as a function of only chronological age failed to provide an adequate representation of cognitive change. Disease progression accounted for virtually all of the memory loss in the 25% of the sample that developed diagnosable dementia. In the remainder of the sample, both chronological age and study attrition contributed to observed memory loss. These results suggest that much of memory loss in aging adults may be attributable to the progression of preclinical dementia and other nonnormative aging processes that are not captured by chronological age. 相似文献

The main purpose of this study is to explore the associations between causal attributions to others, blaming others and mothers' adjustment to the birth of a child with Down syndrome (DS). Participants (n?=?214) rated causal attributions to others and blaming others, and completed five measures of adjustment: anger, anxiety, depression, parenting stress, and attitudes towards the child. The adjustment of three groups of mothers was compared: (i) those who made no attributions to others (ii) those who made causal attributions but did not blame, and (iii) those who blamed others. Four years after the births of their children with DS, 16% of mothers blamed others and 17% made causal attributions but did not blame others for this outcome. Those who blamed others had higher levels of anger, anxiety, depression, parenting stress and more negative attitudes towards their children with DS than did those who made causal attributions but did not blame, and those who made who made no attributions to others. The adjustment of the latter two groups did not differ. Investigating blame rather than causal attributions may be a more fruitful area for future research aimed at understanding and facilitating adjustment to illness and other negative life events. 相似文献

Three studies examined the hypothesis that the relation between self-rated happy affect and overall smiling during dyadic interactions is moderated by one's relative power. In all 3 studies, interpersonal power was experimentally manipulated, and smiling and self-reported happy affect were measured during and after the interaction, respectively. Happy affect was positively correlated with overall smiling for both low-power and high-power participants. Moreover, the correlations for both low- and high-power participants were comparable to those found when power roles were not unequal or made salient, based on analysis of the present studies as well as comparison with the previously published literature. Happy affect and overall smiling had a positive relation that was not moderated by interpersonal power. 相似文献

Two secondary students with moderate disabilities (one per classroom) attended Advanced English classes with peers without disabilities in a rural high school. In additional to conducting planned daily instruction, each English teacher also systematically presented three sets of information (two facts per set) to each student with disabilities during the course of the class using a parallel treatments design. Each set of information included a fact related to the English class (e.g., Begin each sentence with a capital letter.) and a fact not related to the English class (e.g., The governor of Kentucky is Paul Patton.). The special education teacher conducted daily probe sessions to document acquisition. Of the six facts presented to each student with disabilities, one student acquired two related facts and one unrelated fact, while the other student acquired two related and two unrelated facts. This investigation implies that students who are fully included can acquire information presented by the regular classroom teacher during the course of a typical class and that teachers can facilitate learning by planning to present such information in a systematic fashion. 相似文献

We posit that pride and arrogance are tolerated for high-status group members but are repudiated for low-status group members. Thus, we predict that Blacks, but not Whites, who behave arrogantly will be penalized. Specifically, we investigated the context of penalties against football players for “celebrating” after touchdowns. We propose that such celebrations reflect a racially biased “hubris penalty” because: (1) celebrations are primarily perceived as displays of arrogance (rather than exuberance), and (2) arrogance is penalized for Black but not White players. Three experiments demonstrate that all players who celebrated after touchdowns were perceived as more arrogant than those who did not celebrate. Although celebratory Black and White players were perceived as being equally arrogant, Black players were penalized with lower compensation whereas White players were not. Mediation analyses show that perceived arrogance mediated the effect of celebration on compensation, even when controlling for perceived aggression. 相似文献

In three experiments, rats received exposure to a sucrose solution followed by conditioning with a neutral flavor as the conditioned stimulus (CS) and sucrose as the unconditioned stimulus (US). In Experiments 1 and 2, some rats were given both the preexposure and the conditioning phases in a highly familiar context (the homecage), whereas other animals received both phases in a novel and distinctive context. In both cases the magnitude of the conditioning effect was reduced by preexposure to the US. Experiment 3 directly assessed the possible role of contextual cues by changing the context between the exposure phase and the conditioning phase but found no loss of the US-preexposure effect in these conditions. These results lend no support to the blocking-by-context account of the US-preexposure effect; alternative interpretations are considered. 相似文献

Group identification predicts adherence to a group’s norms, values, beliefs, and behaviors. The ability to accurately perceive another’s degree of group identification may be important for predicting the other’s beliefs and actions. In two studies, we examine friends’ accuracy and bias in rating identification with social categories. Friends were asked to rate one another’s and their own identification with state (Studies 1 and 2), national, and global citizen (Study 2) social identities. Across both studies, friends were shown to be both accurate and biased in rating one another’s identification. Thus, although friends may project identification onto a friend (i.e., bias), friends are also able to accurately predict one another’s degree of connection to social groups. Furthermore, friends’ greater frequency of contact was found to increase accuracy in prediction. Together, the results provide initial evidence for future research examining person perception and intergroup interactions. 相似文献
