Role of Timing of Visual Monitoring and Motor Rehearsal in Observational Learning of Action Patterns
This experiment tested the hypothesis that observational learning is enhanced by visual monitoring of enactments that is optimally timed for conception-action matching and by motor rehearsal that serves to refine the cognitive representation. Subjects observed a modeled action pattern, after which they enacted it with either concurrent, delayed, or no visual monitoring. They then engaged in motor rehearsal or did not rehearse the action pattern. Development of the cognitive representation of the modeled action was also measured. Concurrent visual monitoring of enactments greatly facilitated observational learning, whereas delayed visual monitoring did not affect the acquisition process. Rehearsal aided cognitive representation and behavioral reproduction. The more accurate the cognitive representation of the modeled action pattern, the more skilled were the subsequent reproductions of it. After gaining proficiency in converting conception to action, subjects showed no decline in reproduction accuracy when modeling and visual monitoring were withdrawn. 相似文献

AbstractObjective: Without a supply of blood, health services could not meet their clinical needs. Similarly, organs for transplantation save and transform lives. Donations are acts of generosity that are traditionally seen as altruistic, and accordingly, interventions to recruit and retain blood and organ donors have focused on altruism. We review the predictors, prevalence and correlates of these two behaviours, how effective interventions have been, and draw common themes.Design: Narrative review.Results: We highlight that both recipients and donors benefit, and as such neither blood nor organ donation is purely altruistic. We also highlight health problems associated with both types of donation. In evaluating interventions, we highlight that a move to an opt-out policy for organ donation may not be the simple fix it is believed to be, and propose interventions to enhance the effectiveness of an opt-in policy (e.g. social media updates). We show that incentives, text messaging, feedback and a focus on prosocial emotions (e.g. ‘warm-glow’, ‘gratitude’) may be effective interventions for both blood and organ donation. Interventions designed to reduce fainting (e.g. water pre-loading) are also effective for blood donation.Conclusions: We conclude that affect is key to understanding both types of donation and in designing effective interventions. 相似文献

Abstract Patients suffering from chronic stable angina pectoris were allocated to one of four conditions: stress management training, exercise training, combined stress management and exercise, or waiting list control. Patients undertook an exercise tolerance test before and after intervention, and at follow-up assessment eight weeks later. They also kept a daily diary of the frequency, duration and intensity of all angina episodes, and recorded the amount of medication taken, for the week preceding and the week following intervention, as well as for the eighth week of follow-up. Patients who undertook the combined stress management and exercise programme faired best. They showed sustained gains in achieved workload on the exercise tolerance test at no cost in terms of ischaemia, as measured by ST-segment depression. They also registered less frequent angina attacks following intervention than the exercise only and waiting list control patients, and reported reduced reliance on medication; the latter benefit was sustained at follow-up. These clinical dividends invite further study of combined stress management and exercise training in angina pectoris. 相似文献

A sample of 128 Ss differing in flying experience were compared in their travel preferences and in their drawings of airplanes. Significant sex differences were found, with males drawing more “realistic” airplanes; and females, larger airplanes. Those males who had flown and who indicated motion in their drawings tended to report some experience of motion sickness. Those females who had flown and who indicated motion in their drawings tended to report fear of high places. 相似文献

Rats exposed to a simultaneous compound of a flavor and sucrose subsequently exhibited a preference for the flavor over water. This preference persisted across repeated testing even though the flavor was presented in the absence of sucrose. The preference did, however, extinguish if the rats were hungry when trained or tested, or if they had been reexposed to sucrose between training and test. Though failing to extinguish the preference, presentation of the flavor outside the compound protected it from the effects of sucrose devaluation, indicating that these presentations extinguished the within-compound association between the flavor and sucrose. The authors conclude that the hedonic reaction elicited by sucrose imbues the flavor with the same hedonic properties, and these properties maintain the preference independently of the flavor-sucrose association. 相似文献
