Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments were designed to determine whether consummatory behavior is similarly affected by downshifts of equal proportions. Within limits, the degree of consummatory responding during incentive downshift was similar with equal ratios of test concentration to training concentration. Thus, 32–4% and 16–2% downshifts (1:8 test/training ratios) caused similar levels of consummatory behavior, despite differences in the absolute concentrations of the solutions involved in the downshift. An interpretation based on sensory contrast was discarded because of the long intervals between training and test solutions (40 min and 24 h in Experiments 1 and 2, respectively). It is suggested that Weber’s law regulates behavioral suppression after reward downshifts. A theoretical framework for the interpretation of these data is presented. 相似文献

This study extends the branding literature by examining the psychological processes by which consumers evaluate brand alliances. The theoretical basis for this study is the development of models of context effects in brand evaluations (Meyers-Levy & Sternthal 1993 and Levin & Levin 2000). Of particular interest is how dual branding (two restaurant brands with shared features) influences transfer of affect between brands. Although there was a contrast effect in both the separate and dual brand conditions, this contrast effect was significantly reduced in the dual brand condition. Marketing implications of forming brand alliances are discussed. 相似文献

Scientific research progresses along planned (programmatic research) and unplanned (discovery research) paths. In the current investigation, we attempted to conduct a single-case evaluation of the overjustification effect (i.e., programmatic research). Results of the initial analysis were contrary to the overjustification hypothesis in that removal of the reward contingency produced an increase in responding. Based on this unexpected finding, we conducted subsequent analyses to further evaluate the mechanisms underlying these results (i.e., discovery research). Results of the additional analyses suggested that the reward contingency functioned as punishment (because the participant preferred the task to the rewards) and that withdrawal of the contingency produced punishment contrast. 相似文献

Adams and Dziobiak proved that any finite-to-finite universal quasivariety must be Q-universal, and then asked whether a somewhat weaker hypothesis could lead to the same conclusion. We show that their original hypothesis cannot be weakened to its naturally extreme form.To Professor Ale Pultr on his 65th birthdayThe authors gratefully acknowledge the support of the NSERC of Canada, of the project LN00A056 of the Czech Ministry of Education, and also of the Grant Agency of Czech Republic under the grant 201/02/0148.Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by

People sometimes say they are “moved” or “touched” by something. Although the experience is familiar to most, systematic research on being moved has just begun. The current research aims to advance our understanding of the prototypical elicitors of being moved. We tested the hypothesis that being moved is elicited by core values (i.e. values that are particularly central to being human) that manifest themselves in circumstances that are unfavourable to their emergence. In three experiments, two with text stimuli and one with pictorial stimuli, we found compelling evidence that the same core value (e.g. love, willpower, beauty) is perceived as more moving when it emerges in unfavourable than in favourable circumstances. The effect was found in both males and females, although stronger in the latter group, and across all investigated core values, although love was generally more moving than other core values. The theoretical and practical significance of these findings is discussed. 相似文献

This article argues for acknowledging the existence of an absolute distinction between faith and science. It is often assumed in the science and religion debate that such a distinction would be ahistorical and uncontextual. After discussing this critique, the analogy with love and facts will be used to explain how an absolute distinction between faith and science may exist nonetheless. This contrast, however, does not imply compartmentalization. It is shown that the absolute distinction between faith and science is of crucial importance to understand the historical contexts that so many contributors to the science and religion debate refer to in their argument against the approaches of Independence or Contrast. The article concludes that within our messy and complex practices there is an absolute distinction between faith and science—our historical contexts cannot be understood without it. 相似文献

从语法规则复杂性(复杂语法vs.简单语法)的角度考察选择性注意在人工语法学习中的必要性,并且比较两种非法序列下的成绩差异来检验被选择忽视的语法规则是否能被习得却未能在测验阶段体现出来。结果表明纵使降低被选择注意的语法的复杂性,被忽视的语法也未被成功习得,只有被选择注意的语法才能被习得;两种非法序列下的正确率无显著差异,即非法序列b所遵循的被忽略的语法未能在分类判断中起作用。选择性注意是语法规则被习得的关键。 相似文献

Modafinil is a drug licensed for the treatment of narcolepsy and sleep apnea. Recently, modafinil has been reported to be used as a pharmacological cognitive enhancer by healthy individuals with no psychiatric disorders. This paper reports on a study that investigated the effects of modafinil on divergent and convergent thinking tasks of creativity. Sixty‐four healthy male (n = 31) and female (n = 33) volunteers participated in a randomized double‐blind placebo‐controlled parallel group design study. For the convergent thinking tasks, modafinil had no significant main effect on the Group Embedded Figures Task and the Remote Associates Task (RAT). However, a median split analysis showed that modafinil participants low in creativity personality trait had significantly higher RAT scores (Mean [M] = 6.85, SD = 3.39; 95% confidence interval [95% CI]: 5.53–8.2) than those high in creativity personality trait (M = 4.27, SD = 3.0; 95% CI: 2.4–6.0). For the divergent thinking tasks, relative to placebo (M = 1.195, SD = 0.28; 95% CI: 1.0–1.3), modafinil (M = 0.77, SD = 0.37; 95% CI: 0.63–0.92) significantly reduced the performance of flexibility scores and marginally reduced the elaboration scores as measured by the Abbreviated Torrance Test for Adults (ATTA). Overall, participants on modafinil (M = 6.3, SD = 2.6; 95% CI: 5.3–7.4) had significantly lower ATTA scores relative to participants on placebo (M = 9.5, SD = 2.3; 95% CI: 8.6–10.4). These results indicate that modafinil might reduce divergent thinking of creativity in healthy individuals. They suggest that, rather than being a more general cognitive enhancer, modafinil might have negative and subtle effects on creativity. However, the results are from a small‐scale trial, which tested a small number of participants. Therefore, the results need to be interpreted with caution. A replication with a large sample of participants is recommended. 相似文献
