Kamin (1969) reported that after rats had been trained with one CS predicting shock, they learned virtually nothing about a second CS added to the first to form a compound--provided that the shock remained unchanged. If, however, the shock was either increased or omitted at the same time that the new CS was added, it acquired significant excitatory or inhibitory strength. Both these results were confirmed in the present experiment. In addition, however, it was found that this excitatory or inhibitory conditioning to the added element could itself be blocked if the shock remained unchanged for the first four trials after the addition of the new element. This finding implies that blocking is not due to any limitation on attentional or associative capacity, but rather occurs when subjects learn that a particular stimulus is redundant, i.e. that it predicts no change in reinforcement. 相似文献

The present paper reports on a case of a now-16-year-old girl who for most of her life suffered an extreme degree of social isolation and experiential deprivation. It summarizes her language acquisition which is occurring past the hypothesized “critical period” and the implications of this language development as related to hemispheric maturation and the development of lateralization. The results of a series of dichotic listening tests administered to her are included. 相似文献

Misalignment and Misperception in Preferences to Utilize Family‐Friendly Benefits: Implications for Benefit Utilization and Work–Family Conflict 下载免费PDF全文
Despite their increasing popularity, family‐friendly benefits are frequently underutilized. Drawing on literatures concerning social norms and pluralistic ignorance, this study examines the role of personal preference, group norm misalignment, and misperception of group norms on employees’ utilization of family‐friendly benefits. In 2 samples (154 firefighters and 440 nurses) across 3 data collection periods, we found that when employees’ preferences for benefit utilization were misaligned with the perceived group norm, they adjusted their family‐friendly benefit utilization in a manner congruent with the norm, even when that norm was misperceived. Further, we found that family‐friendly benefit utilization was negatively associated with work–family conflict. Together, our findings suggest that misperceived social norms regarding family‐friendly benefit utilization can lead to situations whereby employees do not utilize family‐friendly benefits because they mistakenly perceive utilization is not socially accepted and, as a result, experience higher work–family conflict. 相似文献

To advance international mental health assessment, instruments that have been internationally validated are needed. To this end, we analyzed ratings from 14 societies on the Adult Behavior Checklist (ABCL), a collateral-report form parallel to the Adult Self-Report (ASR; Achenbach and Rescorla 2003) for ages 18 to 59. Both the ABCL and the ASR assess problems, personal strengths, and adaptive functioning. For a sample of 8322 see note below collaterals, we found strong consistency across societies regarding which ABCL problem items tended to obtain relatively low, medium, or high ratings. Most societal effect sizes (ESs) for problem scale scores were small to medium (< 13.9 %), but the ES for the ABCL Personal Strengths scale was 25 %. For most of the same participants (N = 8,302), we analyzed cross-informant agreement between self-reports on the ASR and collateral reports on the ABCL. Cross-informant correlations for problem scale scores averaged .47, with considerable societal variation. Problem score means were higher on the ASR than the ABCL in every society, but the size of the difference varied across societies. Mean item ratings on the ABCL and ASR were highly correlated within every society (mean r = .92), but within-dyad item rating agreement varied widely in every society (mean r = .39). In all societies, non-corroboration of self-reported deviance and of collateral-reported deviance was common. Overall findings indicated considerable similarity but also some important differences in collateral-reported problems and adaptive functioning across 14 societies. 相似文献

Hanley,Smith, and Hadfield (1998) showed that when participants were asked to recognize famous people from hearing their voice , there was a relatively large number of trials in which the celebrity's voice was felt to be familiar but biographical information about the person could not be retrieved. When a face was found familiar, however, the celebrity's occupation was significantly more likely to be recalled. This finding is consistent with the view that it is much more difficult to associate biographical information with voices than with faces. Nevertheless, recognition level was much lower for voices than for faces in Hanleyet al.'s study,and participants made significantly more false alarms in the voice condition. In the present study, recognition performance in the face condition was brought down to the same level as recognition in the voice condition by presenting the faces out of focus. Under these circumstances, it proved just as difficult to recall the occupations of faces found familiar as it was to recall the occupations of voices found familiar. In other words, there was an equally large number of familiar-only responses when faces were presented out of focus as in the voice condition. It is argued that these results provide no support for the view that it is relatively difficult to associate biographical information with a person's voice. It is suggested instead that associative connections between processing units at different levels in the voice-processing system are much weaker than is the case with the corresponding units in the face-processing system. This will reduce the recall of occupations from voices even when the voice has been found familiar. A simulation was performed using the latest version of the IAC model of person recognition (Burton, Bruce, & Hancock, 1999) which demonstrated that the model can readily accommodate the pattern of results obtained in this study. 相似文献

Research exploring the effects of labeling on maternal perceptions and behaviors was extended by simultaneously examining the cognitive and behavioral effects of prematurity stereotyping with both mothers of full‐term and premature infants, and by examining the effects of an information‐based intervention on the stereotyped responses of mothers of premature infants. An experimental design wherein mothers of both full‐term and premature infants were randomly assigned to interact with, and then rate, either a full‐term or premature infant who was described as either full‐term or premature was employed to test several hypotheses. Two hypotheses related to prematurity stereotyping received support: mothers showed more positive responses to infants labeled full‐term than to infants labeled premature, and mothers of full‐term infants exhibited more prematurity stereotyping than did mothers of premature infants. The hypothesis concerning gender effects also was supported, with mothers showing more positive responses to male infants than to female infants. In contrast to expectations, a brief cognitive intervention provided to some mothers of premature infants failed to reduce stereotyping, and, indeed, appeared to increase stereotyping. These results are compared with the results of previous studies, most of which did not include actual interactions between mothers and infants, and the implications of these results are considered. © 2000 Michigan Association for Infant Mental Health. 相似文献

The present study sought to explore how women's life experiences influenced their beliefs, and how those beliefs in turn influenced feminist self-identification. Additionally, we sought to determine whether feminist self-identification led to increased collective action on behalf of women. Female participants (N?=?282) from two US college campuses and online listservs completed an online survey assessing feminist self-identification, collective action, and life experiences. Conservative, liberal, and radical beliefs were assessed as were evaluations of feminists. A structural equation model was used to explore these relationships; life experiences were found to influence women's beliefs, which in turn influenced feminist self-identification, which influenced collective action. We found that life experiences may serve as a catalyst for both feminist self-identification and collective action. 相似文献
