This study investigated the hypothesis that purposeful activity is an intrinsic motivator. We hypothesized that subjects would take longer to perceive themselves to be working hard and would have a higher heart rate increase when working on a product-oriented activity. Fifteen subjects sanded a cutting board that they could keep and a piece of wood that they could not keep until they reached a rating of 15 (hard) on the Borg Rating Scale of Perceived Exertion. No significant differences were found in the subjects' heart rate increase or in the time it took subjects to perceive themselves as working hard. Subjects reported significantly more enjoyment in sanding the cutting board than in sanding the wood, and significance increased further upon completion of the sanding board. Ex post facto, when subjects were categorized into three groups depending upon the degree of liking for each activity, it appeared that the degree of liking may be important in predicting exercise effort. Implications for practice and further research are discussed.
本研究探讨了“有目的的活动是一种内在激励因素”这一假设。我们假设，在从事以产品为导向的活动时，受试者会花费更长时间才意识到自己在努力工作，并且心率升高幅度会更大。15名受试者打磨一块他们可以保留的砧板和一块他们不能保留的木头，直到他们在伯格自觉用力程度量表上达到15级（用力）。在受试者的心率升高情况或他们意识到自己在努力工作所花费的时间方面，未发现显著差异。受试者报告称，打磨砧板比打磨木头更有趣，并且在完成砧板打磨后趣味性进一步增强。事后，当根据对每项活动的喜爱程度将受试者分为三组时，似乎喜爱程度在预测锻炼努力程度方面可能很重要。文中还讨论了对实践和进一步研究的启示。
