The role of arm proprioception in motor learning was investigated in experiments in which, by moving the arm, subjects followed the motion of a target displayed on a monitor screen. Adaptive capabilities were tested in visuomanual tracking tasks following alterations in the relationship between the observer's actual arm movement and visual feedback of the arm movement given by a cursor motion on the screen. Tracking performance and adaptive changes, measured in terms of spatiotemporal error, tracking trajectory curvature, and spatial gain, were compared in 7 control subjects (CSs) and in 1 deafferented subject (DS). CSs adapted appropriately to altered visuomanual relationships; those changes were present in trials immediately after restoration of normal scaling. In contrast, although the DS modified his tracking strategy from trial to trial according to the altered conditions, he did not show plastic changes in internal visuomanual scaling. Like the results of prismatic adaptation experiments, the present results suggest that arm proprioception contributes to the plastic changes that follow alterations in the scaling of visuomanual gain. 相似文献

This study investigated whether structured or unstructured questioning strategies, combined with two levels of domain knowledge and text coherence, significantly affect text memory and text learning. Results of this study suggest that high domain knowledge and structured questioning strategies are the most reliable predictors of text memory and text learning. Several main effects favoring high domain knowledge arose on text memory and, to a lesser extent, text learning measures. Significant results involving structured questioning techniques (i.e., signal words and generic question stems) were detected primarily through interaction effects and one main effect. While not always significantly superior, generic question stem participants outperformed their signal word and unguided questioning counterparts on the majority of text memory and text learning variables. 相似文献

Intertemporal tradeoffs are ubiquitous in decision making, yet preferences for current versus future losses are rarely explored in empirical research. Whereas rational‐economic theory posits that neither outcome sign (gains vs. losses) nor outcome magnitude (small vs. large) should affect delay discount rates, both do, and moreover, they interact: in three studies, we show that whereas large gains are discounted less than small gains, large losses are discounted more than small losses. This interaction can be understood through a reconceptualization of fixed‐cost present bias, which has traditionally described a psychological preference for immediate rewards. First, our results establish present bias for losses—a psychological preference to have losses over with now. Present bias thus predicts increased discounting of future gains but decreased (or even negative) discounting of future losses. Second, because present bias preferences do not scale with the magnitude of possible gains or losses, they play a larger role, relative to other motivations for discounting, for small magnitude intertemporal decisions than for large magnitude intertemporal decisions. Present bias thus predicts less discounting of large gains than small gains but more discounting of large losses than small losses. The present research is the first to demonstrate that the effect of outcome magnitude on discount rates may be opposite for gains and losses and also the first to offer a theory (an extension of present bias) and process data to explain this interaction. The results suggest that policy efforts to encourage future‐oriented choices should frame outcomes as large gains or small losses. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Norenzayan's book is an ambitious attempt to integrate recent research from behavioral economics and social psychology, particularly priming studies, into a book about religion. If the account is meant as an explanation of religion or big religion, it does not succeed. If it has more modest aims, namely to describe how surveillance institutions, of which big religion is one important class, can sometimes lead to cooperation and conflict, then it is quite successful in doing so. 相似文献

Past research has found negative relationships between neighborhood structural disadvantage and students’ academic outcomes. Comparatively little work has evaluated the associations between characteristics of neighborhoods and schools themselves. This study explored the longitudinal, reciprocal relationships between neighborhood crime and school-level academic achievement within 500 urban schools. Results revealed that higher neighborhood crime (and particularly violent crime) predicted decreases in school academic achievement across time. School climate emerged as one possible mechanism within this relationship, with higher neighborhood crime predicting decreases in socioemotional learning and safety, but not academic rigor. All three dimensions of school climate were predictive of changes in academic achievement. Although this research supports a primarily unidirectional hypothesis of neighborhoods’ impacts on embedded settings, additional work is needed to understand these relationships using additional conceptualizations of neighborhood climate. 相似文献

This article focuses on the key relationship marketing tools of customer service, loyalty/rewards programs, brand/store community, personalization and customization, and their relationship with customer retention. The relationship between customer service, loyalty/rewards programs, customization, personalization, brand/store community and customer retention were examined via an empirical investigation of 450 loyalty/reward program members of three retail stores in Malaysia. The administration of the survey was personally administered but self‐completed. Four of the five relationship marketing tools, namely, customer service, loyalty/rewards programs, brand/store community and personalization, had a significant positive relationship with customer retention. The findings provided valuable insights into the loyalty program management practices of retail stores in a developing country context. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

The purpose of this research study was to evaluate faculty perceptions regarding student self-plagiarism or recycling of student papers. Although there is a plethora of information on plagiarism and faculty who self-plagiarize in publications, there is very little research on how faculty members perceive students re-using all or part of a previously completed assignment in a second assignment. With the wide use of plagiarism detection software, this issue becomes even more crucial. A population of 340 faculty members from two private universities at three different sites was surveyed in Fall 2012 semester regarding their perceptions of student self-plagiarism. A total of 89 faculty responded for a return rate of 26.2 %. Overall, institutional policies on self-plagiarism did not exist and faculty did not clearly understand the concept and believed their students did not either. Although faculty agreed students need to be educated on self-plagiarism, faculty assumed students had previously been educated on plagiarism as well as self-plagiarism; only 13 % ensured students understood this concept. 相似文献
