关键词对精加工推理的影响作用初探 总被引:2,自引:0,他引:2
本实验研究在文本中突出关键词对精加工推理的产生水平和产生阶段的影响。研究采用了让被试阅读后做测试题的方法,通过分析测试题的成绩得出的结果表明:在文章中突出关键词有助于产生近推理和内涵推理,且使这两类推理更有可能在阅读过程中产生。本研究补充了McDaniel和Donnelly 1996年的研究结果。 相似文献

本研究以982名初中学生为被试,采用验证性因素分析和多元回归方法对个人目标取向、课堂目标结构及文化因素与学业求助策略的关系进行研究。结果表明:(1)个人目标取向可以区分出任务取向、趋向型自我取向和逃避型自我取向,它们对学业求助的影响是不同的,只有逃避型自我取向的学生才倾向于作不利于学习的执行性求助。(2)课堂目标结构对学业求助有影响 ,在任务取向的课堂里 ,学生倾向于作工具性求助。(3)文化因素对学业求助有影响。认同中国求助格言的学生愿意作工具性求助,在意他人评价的学生倾向于回避求助或作执行性求助。(4)个人目标取向、课堂目标结构和文化因素对不同年级学生学业求助的影响模式不同。 相似文献

Three experiments were designed to test 4- and 6-year-old children's causal inferences in interpersonal settings where emotions (glad, angry, and sad) were effect responses. The results showed that emotion and orientation (towards or away from) were central cues, and that sex and age also were used to some extent. Cues related to regularity philosophic notions (e.g. David Hume), such as contiguity in time and space, and time order of cause and effect were little used by comparison. The results raise questions about the basic role attributed to regularity cues both by philosophers and psychologists, and suggest a multiple cue contribution rather than a basic cue generalization approach to causal cognition development. 相似文献

归因过程“背景效应假设”的初步实验研究 总被引:4,自引:1,他引:3
通过两个实验考证了归因过程的“背景效应假设”:实验1表明,当要求活动者和观察者采用同样的背景事件时.他们之间的归因差异消失了;实验2表明,当有其它的背景信息可供参考时,被试就不再完全按照Kelley所假定的一致性和区别性信息进行归因推断。 相似文献

Three experiments explored the possibility of retrospective inference in the rat. Experiment 1 revealed that poisoning of an element of a taste compound after single compound poisoning enhanced aversion to the other element, and that presentation of an element without poison after the compound poisoning reduced aversion to the other element. These results were opposite to those predicted by retrospective inference. Experiment 2 eliminated some confounding variables and examined the effect of element poisoning after compound poisoning. The result again was opposite to what the retrospective view predicts. The results, however, accorded with the idea that within-compound learning was established during compound presentation, and subsequent poisoning or nonpoisoning of one element affected response to the other element via the within-compound learning. In Experiment 3, the possibility of within-compound learning was reduced by using sequential presentation of tastes, but there was no indication of retrospective inference even under this condition. 相似文献

This research investigated the role of leadership functions in a context of intergroup negotiation by using a simulation game of inter-regional conflict and cooperation (SIRC2 ). As a part of their social psychology course, 151 undergraduate students participated. It was hypothesized that there are four leadership factors in an intergroup context: in-group performance, in-group maintenance, out-group negotiation performance, and out-group relation maintenance. According to a factor analysis, however, the functions of in-group performance and out-group performance merged into the same category and could not be differentiated independently. Moreover, this research provided evidence that opportunities for intergroup communication and the amount of resources available to each group can facilitate these leadership functions. This study also found links between leadership functions and group outcomes. In a group with members who were homogeneous and facing common survival problems, the in-group/out-group performance function facilitated the achievement of the group goal. On the other hand, in a group with members with different roles, and who were self-sufficient for survival, the in-group maintenance function facilitated the achievement of the group goal. Moreover, in the intergroup context, the out-group relationship maintenance function was also important for group goal attainment. These results were interpreted using the path–goal theory and Fiedler's contingency theory. 相似文献

An information-theoretic framework is used to analyze the knowledge content in multivariate cross classified data. Several related measures based directly on the information concept are proposed: the knowledge content (S) of a cross classification, its terseness (Zeta), and the separability (Gamma
X
) of one variable, given all others. Exemplary applications are presented which illustrate the solutions obtained where classical analysis is unsatisfactory, such as optimal grouping, the analysis of very skew tables, or the interpretation of well-known paradoxes. Further, the separability suggests a solution for the classic problem of inductive inference which is independent of sample size. 相似文献
