In two experiments, rats received noncontingent pairings of two stimuli with food reward, one paired with small reward and the other with large reward, and received bar press training with large reward or with small reward. When the noncontingent stimuli (NS) were presented for test during subsequent rewarded bar pressing and during early extinction of bar pressing, responding for each group was faster in the presence of the NS which was paired with the same reward magnitude that group received in bar press training than to the NS which had been paired with a different reward magnitude. As extinction progressed, all groups responded more slowly in the presence of the NS which had been paired with the large reward than in the presence of the NS which had been paired with small reward. These results were interpreted as indicating that responding in the presence of an NS depends on: (i) whether the reward expectancy elicited by the NS has been conditioned to the instrumental response, and (ii) the relationship between the reward expected in the presence of the NS and that received in test. 相似文献

School psychologists serving a national, systematic sample of public elementary and secondary schools were surveyed regarding recent referrals. Most referrals were initiated by school staff members (75% of referrals), and the majority occured initially through formal mechanisms (55% of referrals). Most informal requests for assistance or information eventually became, or were thought likely to become, formal referrals. In 92% of cases, the referral agent's initial communication with the psychologist included some designation of what the pupil was doing or not doing that was viewed as problematic. Poor academic performance was of primary concern in 52% of referrals and social/emotional problems in 31%. More boys were referred than girls, and one-half of referrals from the elementary grades involved pupils in grades K-2. Frequency of referral and reason for referral were not independent of pupil's grade or sex. Reason for referral was independent of time of year (October vs. May) and geographical region. 相似文献

I Can Stomach That! Fearlessness About Death Predicts Attenuated Facial Electromyography Activity in Response to Death‐Related Images 下载免费PDF全文

Objective measures of suicide risk can convey life‐saving information to clinicians, but few such measures exist. This study examined an objective measure of fearlessness about death (FAD), testing whether FAD relates to self‐reported and physiological aversion to death. Females (n = 87) reported FAD and disgust sensitivity, and facial electromyography was used to measure physiological facial responses consistent with disgust while viewing death‐related images. FAD predicted attenuated expression of physiological death aversion, even when controlling for self‐reported death‐related disgust sensitivity. Diminished physiological aversion to death‐related stimuli holds promise as an objective measure of FAD and suicide risk. 相似文献

Ageism is a pervasive force in society that poses a significant threat to the well-being of older women. This article integrates theory, research and practice in an examination of ageism as it relates to therapy with older women. The authors review common stereotypes of older women, and discuss the pervasiveness of these stereotypes using a terror management explanatory framework. Particular attention is also paid to the effects of ageist stereotypes on older women, with especial emphasis on stereotype threat and self-stereotyping concepts. The authors argue that geriatric rehabilitation settings may enhance vulnerability to these negative effects. Finally, strategies for older women to combat ageist stereotypes and develop positive attitudes toward aging are discussed. Implications for therapeutic practice to help older women maintain a satisfying quality of life, despite these stereotypes, are presented throughout the article. The authors recommend interventions embedded in feminist theory, positive psychology, and humanistic and cognitive–behavioral therapies. 相似文献

In this article, both the literature on employee feedback‐seeking behavior and the literature on information seeking by organizational newcomers are reviewed. This review highlights the various motives that affect the decision of whether or not to seek information, shows how the strength of those motives is affected by both characteristics of the individual and characteristics of the organizational context, and reviews evidence that information seeking has beneficial outcomes. The author then offers an integrated model of antecedents, dynamics, forms, and outcomes of employee information seeking and concludes with suggestions for how future research can extend current understanding of employee information seeking. 相似文献
