Review is often more effective when it involves deliberate memory retrieval. However, this advantage may depend on a high rate of retrieval success; students who are less capable with the material may be better served by another activity. In our study, year 9 geography students listened to factual information, then reviewed some of it with a retrieval practice and feedback activity, some with a reading activity and left some unreviewed. We also manipulated the presence of hints during review—hints can affect the rate of retrieval success during practice and are relatively easy for teachers to provide. When tested 1 week later, most students showed a benefit of retrieval practice, even those who had performed poorly during review. There was also some evidence that hints improved learning when they made retrieval practice easier. Our findings suggest that retrieval practice, properly implemented, is advantageous for students of all ability levels. 相似文献

一个新的测量过程框架——对引入认知加工模型的再思考 总被引:1,自引:0,他引:1
从认知任务分析出发的测验设计,核心在于从认知加工的角度对项目底层作答机制作出解释。其中,能够刻画任务难度的模型最有可能与心理计量模型相结合。因而,具备成熟难度法则的各种小型理论或通用理论可以进入测量过程,实现从纯粹误差结构控制的测量到内容导引的测量的转变。在这样一个框架之下,理论对任务上作答过程的理解是否恰当,刺激特性变量与任务难度关系的揭示(即难度法则)是否准确,可以在测量的过程中进行证伪。项目反应理论还未及很好回答的效度问题,可望在这一拓展的框架中获得圆满解决。本文为新的测量过程框架提供了一个示意图。 相似文献

辨别作业难度对返回抑制时间进程的影响 总被引:4,自引:0,他引:4
在返回抑制范式下,利用线索一靶子模式和辨别作业进行了两个实验,探讨辨别作业难度对返回抑制的影响。以大学生为被试。实验一对辨别作业难度采用组间设计;实验二采用组内设计。结果发现,无论是组间比较(实验一),还是组内比较(实验二).复杂辨别作业条件下返回抑制出现时间均比简单辨别作业晚,表明作业难度对返回抑制的时间进程有显著影响。该结果对返回抑制的机制研究有一定的意义。 相似文献

The aim of this study was to analyze the psychometric properties of the Spanish translation of the List of Social Situation Problems (LSSP; S. H. Spence, 1980). The questionnaire was administered to a sample of 388 adolescents between the ages of 12 and 18. Exploratory factor analysis identified four factors: Social Anxiety, Adult Oppositional, Assertiveness, and Making Friends, which accounted for 26.64% of the variance. Internal consistency of the total scale was high ( = .86). Correlations between the LSSP and two self-report measures of social anxiety, the Questionnaire about Interpersonal Difficulties for Adolescents (r = .45) and the Social Phobia and Anxiety Inventory (r = .48), were statistically significant. A significant difference was found between LSSP total scores for adolescents with and without social anxiety (d = 1.14), supporting the construct validity of the scale. 相似文献

This study investigated students' allocation of responding as a function of task difficulty and type of reinforcement contingency (i.e., accuracy based or time based). Four regular education fourth-grade students were presented with two identical stacks of easy and then difficult math worksheets using a reversal design. Regardless of condition, completing problems from each stack of worksheets was reinforced according to a different contingency; one required correct completion of math problems (accuracy based) and one required on-task behavior (time based). Results suggested that 3 of the 4 students preferred the accuracy-based contingency when given easy material and the time-based contingency when given difficult material. One student allocated more responding to the accuracy-based contingency when given easy problems but did not show a clear preference for either contingency with difficult problems. The implications of these findings for designing reinforcement-based programs for tasks of varying difficulty are discussed. 相似文献

ABSTRACTThe standard view of demandingness understands demandingness exclusively as a matter of costs to the agent. The paper discusses whether the standard view must be given up because we should think of demandingness as a matter of difficulty or restriction of options. I will argue that difficulty can indeed increase demandingness, but only insofar as it leads to further costs. As to restrictions of options, I will show that confinement can become costly and thus increase demandingness in three ways, by prohibiting actions that the agent wants to perform in order to promote his well-being, by limiting the development of future preferences and projects and also by making the society less open. The paper thus defends a new variant of the standard view by arguing that difficulty and restrictions of options can increase the demandingness of morality on grounds of being costly. 相似文献

本研究通过创设收益和损失跨期选择情境, 采用不同表征方式(得框架、失框架)的跨期选择任务, 分别探讨了收益和损失情境下的跨期选择是否存在得失框架效应, 及其是否会受任务难度的影响。结果发现:(1)收益型跨期选择只在任务容易时存在得失框架效应, 与失框架相比, 被试在得框架下选择即时获益的概率更高; 任务困难时得失框架效应消失(实验a); (2)损失型跨期选择中不存在得失框架效应(实验b)。结果表明, 得失框架效应在损、益型跨期选择中出现了分离, 收益型跨期选择中的得失框架效应的内在认知机制很可能与风险决策中的框架效应类似并且是一种较为初级的认知加工过程。 相似文献

Extending Fitts' law to a three-dimensional pointing task 总被引:1,自引:0,他引:1
An attempt was made to extend Fitts' law to a three-dimensional movement (pointing) task to enhance its predictive performance in this domain. An experiment was conducted in which 10 subjects performed three-dimensional pointing movements under the manipulation of target size, distance to target and direction to target. As expected, the duration of these three-dimensional movements was rather variable and affected markedly by direction to target. As a result, the variance in the movement times produced was not satisfactorily explained by the conventional Fitts' model. The conventional model was extended by incorporating a directional parameter into the model. The extended model was shown to better fit the data than the conventional Fitts' model, both in terms of r(2) and the standard error of the residual between the measured movement time and the value predicted by model fit. 相似文献

基于关系-表征复杂性模型,从每道应用题涉及集合关系的嵌套程度角度事前分析其关系复杂性,编制了难度序列变化的应用题测验,以考察问题表征能力。采用该测验测查了四至七年级共165名学生,考察事前分析的合理性及表征水平随年龄的变化。结果表明:(1)事前分析对两个事后难度指标(错误率和Rasch模型分析的任务难度)的解释率分别为73.7%、78.7%;该测验得分与测查思维水平层次变化的SOLO分类测验上的得分有较高相关(r=0.65)。(2)四年级的应用题表征水平显著低于五、六、七年级,其他三个年级差异不显著;而且随着问题关系复杂性的增加,年级差异增大。这说明基于关系-表征复杂性模型的事前分析是合理的,据此编制的测验能够测查表征水平随年龄的变化。 相似文献
