Voters typically evaluate an attractive candidate more favorably than an (otherwise equivalent) unattractive candidate. However, some voters “correct” for the biasing influence of physical appearance. This reduces, eliminates, or even reverses the physical attractiveness effect. Correction occurs when political experts evaluate a political candidate under nondistracting conditions. Under these “high cognitive capacity” conditions, voters primarily correct for physical unattractiveness. However, correction fails to occur when voters possess low levels of expertise or are distracted. Thus, in most circumstances, attractive candidates are evaluated more favorably than unattractive candidates. Two experiments provide support for this model of appearance‐based candidate evaluation.  相似文献

The authors surveyed professional counselors (N = 956) to examine self‐efficacy in counseling older adults, contact with older adults, and ageism as related to their interest in working with older adults. Higher self‐efficacy, contact, and positive ageism predicted increased interest. These results and implications for counseling older adults are discussed.  相似文献

Four experiments examine blocking of associative learning by human participants in a disease diagnosis procedure. The results indicate that after a cue is blocked, subsequent learning about the cue is attenuated. This attenuated learning after blocking is obtained for both standard blocking and for backward blocking. Attenuated learning after blocking cannot be accounted for by theories such as the Rescorla-Wagner model that rely on lack of learning about a redundant cue, nor can it be accounted for by extensions of the Rescorla-Wagner model designed to address backward blocking that encode absent cues with negative values. The results are predicted by the hypothesis that people learn not to attend to the blocked cue.  相似文献

The pathology of cardiac disease includes genetic, physical, biochemical, psychological, social, and environmental vectors. Factors contributing to suicide have been identified in these same areas. Survival from an acute cardiac event requires a systematized and multisectoral response. Communities that do not have systematized response capabilities to acute cardiac events have poorer survival outcomes. Suicide prevention and control may also be responsive to an integrated community response system. This paper examines the development of a community cardiac care model, explores potential parallels for a community suicide prevention and control model, and outlines a general systems theory framework for a suicide prevention and control system.  相似文献

The study of experimental extinction and of the spontaneous recovery of the extinguished memory could cast light on neurobiological mechanisms by which internal representations compete to control behavior. In this work, we use a combination of behavioral and molecular methods to dissect subprocesses of experimental extinction of conditioned taste aversion (CTA). Extinction of CTA becomes apparent only 90 min after the extinction trial. This latency is insensitive to muscarinic and β-adrenergic modulation and to protein synthesis inhibition in the insular cortex (IC). Immediately afterwards, however, the extinguishing trace becomes sensitive to β-adrenergic blockade and protein synthesis inhibition. The subsequent kinetics and magnitude of extinction depend on whether a spaced or massed extinction protocol is used. A massed protocol is highly effective in the short run, but results in apparent stagnation of extinction in the long-run, which conceals fast spontaneous recovery of the preextinguished trace. This recovery can be truncated by a β-adrenergic agonist or a cAMP analog in the insular cortex, suggesting that spontaneous overtaking of the behavioral control by the original association is regulated at least in part by β-adrenergic input, probably operating via the cAMP cascade, long after the offset of the conditioned stimulus. Hence, the performance of the subject in experimental extinction is the sum total of multiple, sometimes conflicting, time-dependent processes.  相似文献

Forgetting is often thought of as the inability to remember, but remembering and forgetting allow behavior to adapt to a changing environment in distinct and separable ways. Learning and forgetting were assessed concurrently in two pigeon experiments that involved the same unconventional routine where the schedule of reinforcement changed every session. Sessions were run back-to-back with a 23-h mid-session break such that in a single visit to the testing chamber, a pigeon completed the second half of one session and the first half of the next. The beginning of a new session was either signaled or unsignaled. Experiment 1 involved concurrent variable–interval variable–interval schedules with four possible reinforcer ratios. Response allocation was sensitive to the richer schedule and was retained through the mid-session break. Experiment 2 involved peak interval schedules of varying durations. Temporal discrimination was rapidly acquired before and after the mid-session break, but not retained. Signaling the session change decreased control by past contingencies in both experiments, demonstrating that learning and forgetting can be investigated separately. These results suggest that the temporal structure of training, such as multiple short daily sessions instead of one long session, can meaningfully impact measurement of animals’ capacity to forget and remember.  相似文献

Hospital trauma centers intervene with patients who incur alcohol‐related injuries. This prospective study, using professional counselors and trainees, investigated brief counseling interventions (BCIs). Participants were randomized to either a conventional BCI examining quantity and frequency of drinks or a personalized BCI exploring overintoxication. No statistically significant difference between risky drinkers randomized to either intervention in a hospital trauma center was observed. Findings indicate that a personalized BCI may be an alternative to a quantitative BCI in reducing risky alcohol consumption.  相似文献
