This paper examines whether multiple motivational sources uniquely influence task performance. Using the established framework in the goal-setting literature that suggests a pattern of mediated relationships, we test the relationship between assigned goals, incentives, and intrinsic motivation and task performance. The results show that assigned goals, incentives, and intrinsic motivation each positively influence task performance. However, the magnitude of the relationship varies considerably. The relationship for assigned goals was fully mediated by self-efficacy and self-set goals, whereas only a direct relationship emerged for incentives. The data reveal both direct and indirect relationships associated with intrinsic motivation. 相似文献

A naturalistic in-home investigation of maternal teaching strategies while viewing an educational program (Sesame-Street) and an entertainment program (a situation comedy) was conducted. Fourteen mothers and their pre-school children tape-recorded their coversations while jointly viewing the two television programs. Mothers tooks the role of teacher during both types of programs, but they talked more and asked proportionally more questions about the content of Sesame Street than they did about the content of the situation comedy. Likewise, during Sesame Street, mothers talked more about educationally relevant concepts such as size, color, and number. Children, while watching Sesame Street, engaged in ore labeling of educationally relevant concepts than they did while viewing the situation comedy. During the situation comedy, mothers explained why television characters performed particular behaviors and assigned traits and emotions to characters more frequently than they did during Sesame Street. The findings suggest that the parent may play an important role in helping children maximally utilize television as a teacher. 相似文献

The patient scheduling system in a pediatric outpatient clinic was changed from time-based to problem-based in an A-B-A-B reversal design. During baseline, time-based scheduling was in effect with patients being scheduled in 15-min periods regardless of presenting problem. During intervention, a receptionist matched client problems with time slots so that a more extensive treatment was allocated more time. Problem-based scheduling resulted in a substantial decrease in mean number of minutes spent in clinic across all presenting problems. Waiting time increased to baseline levels when problem-based scheduling was removed and decreased again on reintroduction of the program. A follow-up check conducted 1 month after the end of the second intervention phase revealed that the effects were maintained. The problem-based schedule also resulted in an increase in the proportion of extra time that medical staff had available and produced a positive consumer response. 相似文献

On each of five days the subject of this experiment read aloud different material during an 18-min A1 (base rate), B (experimental), and A2 (extinction) period. No stimulation was delivered during the first three days. On the fourth day, the nonsense word “norg” was presented noncontingently during the experimental period. There was no statistically significant difference between the A1 and B periods on any of these four days. On day five, “wrong” was made contingent on Factor I prolongations during the experimental period. As a result, there was a statistically significant increase in their frequency. When the response consequence was removed in the A2 priod, there was a reliable reduction in prolongations and the frequency closely approximated that found in the A1 period. These data suggest that response-contingent negative stimulation is contraindicated as a clinical tactic for use with Factor I prolongations. It not only failed to suppress them, it increased their frequency. 相似文献

An identical-subject-repeated-measures design, involving two counterbalanced conditions, was employed to investigate adaptation when the presentation of a 100-word list is distributed and when it is massed. In Condition I, the entire list was read aloud during each of five successive trials. Since a specific word reoccurred only after all of the others were displayed, the presentation may be said to be distributed. In contrast, the Condition II presentation was massed. Only after a word was read five times was the next one presented. The results indicate that significant adaptation occurred in both conditions. However, adaptation plateaued in the distributed condition. This was not the case when massing was employed. The among-condition analyses revealed that significantly more adaptation occurred in the massed than in the distributed condition. 相似文献
