青少年学生身体自我特点的初步研究

本研究编制的青少年学生身体自我量表具有较高的信度和效度,该量表包含五个因素：相貌特征、运动特征、身体特征、性特征和负面特征。我国青少年学生的身体自我在总体上不存在性别差异,但女生对自己在运动特征和身材特征上的满意度显著高于男生。从中学生到大学生的年级发展趋势看,青少年学生身体自我的满意度总体上呈下降趋势;随着年级的升高,他们对自己的身体越来有越多的不满意。     

关于动力系统中自我强化和学生期待对学习效率影响的实验研究

本实验考察了在教学活动中,动力系统中自我强化和学生期待两因素与中学生学习效率的关系。结果表明：在其它教学条件相同的情况下,适当地、适时地满足学生期待对初中生学习效率的提高有较明显的作用,而对高中学生则作用不明显;对中学生进行自我强化的训练,有助于高中生学习效率的提高,而对初中生学习效率的作用则不明显;实验中未出现交互作用。     

多动症儿童的智力水平、行为与认知事件相关电位的研究

通过对多动症 (MBD)儿童的智力、行为和认知事件相关电位的分析研究,发现多动症儿童的智力水平正常但均数都低于正常儿童,行为问题的检出率和行为量表指数高于一般正常儿童,反映大脑认知功能的事件相关电位的N2、P3的潜伏期较之正常儿童组均延长,且差异均达到显著性水平。     

Children's and adults' conceptualization and evaluation of lying and truth‐telling

The present study examined children's and adults' categorization and moral judgment of truthful and untruthful statements. 7‐, 9‐ and 11‐year‐old Chinese children and college students read stories in which story characters made truthful or untruthful statements and were asked to classify and evaluate the statements. The statements varied in terms of whether the speaker intended to help or harm a listener and whether the statement was made in a setting that called for informational accuracy or politeness. Results showed that the communicative intent and setting factors jointly influence children's categorization of lying and truth‐telling, which extends an earlier finding (Lee & Ross, 1997) to childhood. Also, we found that children's and adults' moral judgments of lying and truth‐telling were influenced by the communicative intent but not the setting factor. The present results were discussed in terms of Sweetser's (1987) folkloristic model of lying. Copyright © 2009 John Wiley & Sons, Ltd.     

换位棋问题规则的表征与解题正确率间关系的研究

本研究通过对被试求解换位棋过程的记录与分析,重点研究了问题表征在换位棋求解过程中的作用。实验结果表明：（1）正确表征问题规则是解题的必要前提.对问题规则信息的误解和遗漏,是影响解题正确率的重要因素。其中对非隐含问题规则的错误表征也占全部错误表征的很大比率。（2）“关键结构”的发现是解决换位棋的必要条件,对问题规则的错误表征影响“关键结构”的发现.（3）前置问题的解决经验对目标问题的正确表征无显著的影响作用。

Suboptimal tradeoffs in information seeking

Explicit information-seeking actions are needed to evaluate alternative actions in problem-solving tasks. Information-seeking costs are often traded off against the utility of information. We present three experiments that show how subjects adapt to the cost and information structures of environments in a map-navigation task. We found that subjects often stabilize at suboptimal levels of performance. A Bayesian satisficing model (BSM) is proposed and implemented in the ACT-R architecture to predict information-seeking behavior. The BSM uses a local decision rule and a global Bayesian learning mechanism to decide when to stop seeking information. The model matched the human data well, suggesting that adaptation to cost and information structures can be achieved by a simple local decision rule. The local decision rule, however, often limits exploration of the environment and leads to suboptimal performance. We propose that suboptimal performance is an emergent property of the dynamic interactions between cognition and the environment.     

Depression,Confidence, and Decision: Evidence Against Depressive Realism

This research examined how retrospective self-assessments of performance are affected by major depression. To test the validity of the depressive realism versus the selective processing hypotheses, aggregate posttest performance estimates (PTPEs) were obtained from clinically depressed patients and an age-matched comparison group across 4 decision tasks (object recognition, general knowledge, social judgment, and line-length judgment). As expected on the basis of previous findings, both groups were underconfident in their PTPEs, consistently underestimating the percentage of questions they had answered correctly. Contrary to depressive realism, and in partial support of the selective processing account, this underconfidence effect was not reduced but modestly exacerbated in the depressed patients. Further, whereas the PTPEs of the comparison group exceeded that expected on the basis of chance alone those of the depressed individuals did not. The results provide no support for the depressive realism account and suggest that negative biases contribute to metacognitive information processing in major depression.The results reported in this paper are based on an extension of the MSc dissertation of Tiffany Fu, conducted in partial fulfillment of the degree of MSc in Research Methods in Psychology, University of Reading, 2003
