小学儿童学习时间分配决策水平的发展

利用自由回忆,线索回忆和再认三种提取方式,以儿童任务难度预见（EOL）的判断等级与学习时间分配之间的G相关值作为指标,考察了小学儿童学习时间分配决策水平的发展过程。小学2、4、6年级儿童和成人大学生(作为对照)参与本研究,每个年龄组各24人。主要研究结果表明：（1）总体而言,小学各年级儿童,其学习时间分配的决策都受对任务难度预见等级的制约,对EOL判断等级越高的项目,分配的学习时间越长,说明小学儿童具有一定程度的学习时间分配的决策能力;（2）在自由回忆条件下,小学4年级和小学6年级儿童对EOL的判断等级与学习时间之间的G相关值差异显著,表明儿童的决策水平由小学4年级到小学6年级表现出快速发展的趋势;（3）在线索回忆的条件下,小学2年级和4年级儿童G相关值有显著差异,表明决策水平由小学2年级到小学4年级之间有快速发展的趋势;（4）在再认的条件下,小学各年龄儿童学习时间分配的决策水平没有显著性差异,表明再认条件下小学阶段的决策水平进步不显著;（5）在三种提取方式下,小学儿童对任务难度预见判断等级与首次学习时间之间的G相关值都不同程度地低于与总的学习时间之间的相关值。这说明小学儿童在反复学习的过程中在不断调整自己的学习时间分配,调整的程度有随年龄增长而加大的趋势。小学6年级儿童在任务难度预见判断等级与学习时间之间的G相关值已接近成人水平。     

图片部分线索效应的学习时间分配的发展

部分线索效应指让学习者学习一系列材料, 在随后的测试阶段, 给学习者提供先前所学材料的一部分作为提取线索, 让其回忆剩余的材料, 回忆成绩反而比没有提取线索时回忆成绩差的现象。通过3个实验, 以图片为实验材料, 考察了图片部分线索效应学习时间分配的发展特点。实验1考察了图片部分线索效应的边界条件, 结果发现：图片学习中, 以物体名称为线索时, 不存在部分线索效应; 而以图片为线索时, 存在部分线索效应。结果表明：跨域线索是图片部分线索效应的边界条件。实验2利用图片作线索, 考察了图片部分线索效应的发展特点, 结果发现：图片学习中, 不同年龄被试均存在部分线索效应。结果表明：年龄不是图片部分线索效应的边界条件。实验3考察不同年龄被试对部分线索消极作用的记忆监控的发展变化趋势, 结果发现：小学二年级儿童即使经过多次学习, 也不能意识到部分线索的消极作用; 小学五年级儿童经过二次学习后, 方可意识到这种消极作用, 并在部分线索条件下安排了更多的学习时间; 初二和高二年级学生经过一次学习, 即可意识到部分线索的消极作用, 他们均在部分线索条件下安排了更长的学习时间。结果表明：儿童的学习时间分配决策能力在小学二年级到小学五年级之间有一个质的提高; 与初二学生相比, 高二学生对部分线索带来的消极影响做了更多的时间补偿。     

不同任务定向下小学儿童学习时间分配决策水平的发展

研究包含3个实验,分别探查了儿童在“速度定向”、 “准确性定向” 以及“速度和准确性定向”3种任务定向下学习时间分配决策水平的发展。3个实验均采用3×3混合设计,选择小学2年级、小学4年级、小学6年级学生各24人为被试,提供难度不同的3种材料,考查在限定的时间内儿童在3种材料间进行的学习时间分配决策水平的发展。结果：（1）在三种任务定向下,儿童学习时间分配决策水平均随年龄增长而提高。（2）不同的任务定向要求对不同年级儿童学习时间分配决策的影响不同。（3）在本实验条件下,儿童学习时间分配策略的使用,经历了三个阶段：第一个阶段,不使用策略;第二个阶段,使用策略但效果不稳定;第三个阶段,使用策略且有稳定效果     

学生提取自信度判断准确性的发展

采用3×3×2(年龄,材料,性别)三因素混合实验设计,按照学习成绩好、中、差分层随机选取小二、初二、大二学生被试各18名,其中男女各半,利用不同难度的材料,对被试提取自信度准确性的发展进行了考察。被试的判断等级与被试的记忆成绩之间的两点距随年龄而变化。而这种变化在不同难度间有不同的表现。(1)提取自信度准确性从小二到初二发展迅速,表现出显著差异;初二到大二阶段年龄差异不显著。材料难度对不同年级的被试提取自信度判断准确性的影响不同。材料难度越小,提取自信度准确性发展得越早。(2)提取自信度准确性发展的性别差异不显著。     

中学生自恋的年龄特征及其与社会适应的关系:自尊的中介作用

对459名初一到高二学生施测自恋、自尊以及社会适应问卷,以探讨中学生自恋的年龄特征及其与社会适应的关系。结果表明:(1)中学生的自恋不存在性别差异,但是年级差异显著,初三学生的自恋水平要显著低于高一学生。由于年级差异的效应值很小(G²=0.025),要谨慎分析该年级差异。(2)自恋与中学生自我报告的社会适应良好呈显著正相关。(3)自尊在自恋与社会适应的关系间起到了中介作用。     

初中生依恋与主观幸福感:自尊的中介作用

Developmental Patterns of Eyewitness Responses to Repeated and Increasingly Suggestive Questions

Kindergarten, Grade 2, Grade 4, and adult subjects viewed a brief video of two children arguing about the use of a bicycle. One week later subjects were asked for their free recall of the events in the video followed by sets of hierarchically arranged, increasingly suggestive questions that suggested a correct (positive-leading), an incorrect (misleading), or no specific (unbiased-leading) answer, with the final level of questioning for each item being a three-alternative multiple-choice question. Correct free recall varied with age, with the kindergarten and Grade 2 children generally following the lead of the first-level questions more so than the older subjects. Older children were as accurate as adults in responding to questions about the central items, but not so for noncentral items. Developmental differences were found in responses to repeated suggestive questioning, with kindergarten children following misleading questions and changing answers more often than older subjects. On the final, multiple-choice questions, kindergarten children were able to provide the correct answer as often as they had to the initial questions, despite intervening errors. Findings are discussed in terms of the type of questions presented, the repetition factors, and the opportunities for subjects changing their answers in response to subsequent questions about the same item.     

成败情境下不同成就目标取向学生业绩表现的差异

Relationships between personality and time-related strains

Using data from a Dutch representative national sample of 1,249 respondents (40% women and 60% men), all engaged in paid labor, the relationships between Big Five personality traits and time-related strains (i.e., Time Pressure and Work Pressure) were examined. Hierarchical regression analyses showed that Emotional Stability was negatively and Openness to Experience was positively related to both types of time-related strains. Emotional Stability and Agreeableness were more strongly negatively associated with generalized Time Pressure than with context-specific Work Pressure. This supports the Strong versus Weak Situations Hypothesis of Mischel.

Frames of reference for self-evaluation of ability in mathematics

Measures of eight frame-specific self-evaluations of ability in mathematics were used to predict general mathematics self-concept and self-efficacy. Participants were 900 Norwegian students in Grade 6 (n = 277), Grade 9 (n = 236), Grade 11 (n = 263), and adult students attending senior high school (n = 124). Four items measured frame-specific self-evaluation of achievement based on external frames of reference whereas four items measured frame-specific self-evaluation based on internal frames of reference. Regression analyses were used to test relations between the frame-specific self-evaluations and general mathematics self-concept and self-efficacy. The analyses indicated that self-evaluation based on comparison with other students in class (an external frame of reference) and on comparison of mathematics achievement with achievement in other school subjects (an internal frame of reference) were robust predictors of both mathematics self-concept and self-efficacy. The analyses also indicated that students are using multiple frames of reference when evaluating their mathematics ability. Implications of the result for the internal-external frame of reference model are discussed.     

Culture contact and national sentiment

This study investigated the relationship between culture contact and national sentiment in the unique social setting of a newly independent nation. The study tested the hypothesis that for a group of Australian expatriate students at a multi-racial school in Papua New Guinea there would be a positive relationship between number of years of residence in Papua New Guinea and positive attitudes towards national independence. A sample of 75 Australian expatriate students answered a questionnaire that included attitude items, Cantril's ladder measures, and various measures relating to social interaction, social distance, and perceived similarity. Results supported the hypothesis and in general they were consistent with its underlying assumptions, although it was noted that a selective migration interpretation of the findings was also possible.

Extensive training extends numerical abilities of guppies

Recent studies on animal mathematical abilities suggest that all vertebrates show comparable abilities when they are given spontaneous preference tests, such as selecting the larger number of food items, but that mammals and birds generally achieve much better performance than fish when tested with training procedures. At least part of these differences might be due to the fact that fish are usually trained with only one or two dozen trials while extensive training, sometimes with thousands of trials, is normally performed in studies of mammals and birds. To test this hypothesis, female guppies were trained on four consecutive numerical discriminations of increasing difficulty (from 2 vs. 3 to 5 vs. 6 items), with up to 120 trials with each discrimination. Five out of eight subjects discriminated all contrasts up to 4 versus 5 objects at levels significantly better than chance, a much higher limit than the 2 versus 3 limit previously reported in studies that provided fish with only short training sequences. Our findings indicate that the difference in numerical cognition between teleosts and warm-blooded vertebrates might be smaller than previously supposed.
