A hallmark feature of elemental associative learning theories is that multiple cues compete for associative strength when presented with an outcome. Cue competition effects have been observed in humans, both in forward and in backward blocking procedures (e.g., Shanks, 1985) and are often interpreted as evidence for an associative account of human causal learning (e.g., Shanks & Dickinson, 1987). Waldmann and Holyoak (1992), however, demonstrated that cue competition only occurs in predictive, and not diagnostic, learning paradigms. While unexplainable from an associative perspective, this asymmetry readily follows from structural considerations of causal model theory. In this paper, we show that causal models determine the extent of cue competition not only in forward but also in backward blocking designs. Implications for associative and inferential accounts of causal learning are discussed. 相似文献

Gatekeeper training is a common approach for aiding suicidal youth. This study utilizes comparative effectiveness “benchmarks” from established programs to evaluate the Question, Persuade, Refer (QPR) program. The QPR program was implemented with adults (N = 2,389) working in youth‐serving community agencies. Questionnaires assessed suicide prevention knowledge, attitudes, subjective norms, perceived behavioral control, and behaviors. Consistent with benchmarked studies, participants in QPR demonstrated knowledge and suicide prevention behavior gains compared with control groups. Future research should utilize benchmarking methods as a measure of effectiveness, and more thoroughly assess mechanisms that promote behavior change. 相似文献

Social control has the potential to encourage engagement in a healthy lifestyle, but its effectiveness may depend on the nature of the influence attempt. Participants (N = 282) described a situation in which someone attempted to influence their health-related behavior. Experiencing positive social control was associated with a greater tendency to change the behavior and less ignoring/doing nothing, whereas negative social control was associated with a lesser tendency to change the behavior and more hiding of unhealthy behavior. These associations could be accounted for by affective responses to the social control attempts. Results emphasize the need to better understand the regulatory influence of relationships on health behavior and the conditions under which social control is most likely to have health-promoting effects. 相似文献
