教师背景变量对教师教学效果影响的多层线性分析

用《教师教学效果评价问卷(学生版)》问卷对高校181名教师的教学效果进行调查,用多层次分析法对影响教师教学效果的教师背景变量:教师性别、年龄、学历、职称、所教专业、年级、班级大小以及课程类别对教师教学效果影响程度进行分析,目的在于通过用多层分析法更合理分析教师背景变量对教学效果产生的影响,为客观比较教师教学效果之间的差异提供依据。研究结果表明:(1)多层次分析法得到比传统回归分析和方差分析更合理更准确的结果;(2)教师背景变量教师中性别、学历、专业以及所教班级的大小对于教师教学效果评价效果没有显著影响;(3)教师职称、年龄、所教学生年级、课程类别对教师的教学效果有显著影响;(4)所考察的教师水平背景变量对教学效果各个维度教师水平总变异的解释率介于3351%-4278%之间。     

Perceived association between diagnostic and non-diagnostic cues of women’s sexual interest: General Recognition Theory predictors of risk for sexual coercion

Young men’s errors in sexual perception have been linked to sexual coercion. The current investigation sought to explicate the perceptual and decisional sources of these social perception errors, as well as their link to risk for sexual violence. General Recognition Theory (GRT; [Ashby, F. G., & Townsend, J. T. (1986). Varieties of perceptual independence. Psychological Review, 93, 154-179]) was used to estimate participants’ ability to discriminate between affective cues and clothing style cues and to measure illusory correlations between men’s perception of women’s clothing style and sexual interest. High-risk men were less sensitive to the distinction between women’s friendly and sexual interest cues relative to other men. In addition, they were more likely to perceive an illusory correlation between women’s diagnostic sexual interest cues (e.g., facial affect) and non-diagnostic cues (e.g., provocative clothing), which increases the probability that high-risk men will misperceive friendly women as intending to communicate sexual interest. The results provide information about the degree of risk conferred by individual differences in perceptual processing of women’s interest cues, and also illustrate how translational scientists might adapt GRT to examine research questions about individual differences in social perception.     

Probability estimation in poker: A qualified success for unaided judgment

Poker players make strategic decisions on the basis of imperfect information, which are informed by their assessment of the probability they will hold the best set of cards among all players at the conclusion of the hand. Exact mental calculations of this probability are impossible—therefore, players must use judgment to estimate their chances. In three studies, 69 moderately experienced poker players estimated the probability of obtaining the best cards among all players, based on the limited information that is known in the early stages of a hand. Although several of the conditions typically associated with well‐calibrated judgment did not apply, players' judgments were generally accurate. The correlation between judged and true probabilities was r > .8 for over five‐sixths of the participants, and when judgments were averaged across players and within hands this correlation was .96. Players slightly overestimated their chance of obtaining the best cards, mainly where this probability was low to moderate (<.7). Probability estimates were slightly too strongly related to the strength of the two cards that a player holds (known only to themselves), and insufficiently influenced by the number of opponents. Seemingly, players show somewhat insufficient regard for the cards that other players could be holding and the potential for opponents to acquire a strong hand. The results show that even when judgment heuristics are used to good effect in a complex probability estimation task, predictable errors can still be observed at the margins of performance.

选项框架和认知负载对风险决策的影响

本研究采用实验法探讨了选项框架和认知负载对风险决策的影响。结果发现:(1)不同的认知负载条件下,被试在正向框架下表现出风险回避,负向框架下表现出风险寻求,出现了框架效应现象;(2)相对于认知负载条件下,被试在无认知负载的负向框架下更偏好于风险选项,而正向框架下的风险偏好没有显著变化,即无认知负载条件下框架效应较强。这表明,框架效应不仅仅是启发式系统作用的结果,分析式系统也在其中发挥着重要的作用。     

货币幻觉的心理机制与影响因素

货币幻觉是指经济交易活动中,人们因倾向于以货币的名义价值而非实际价值思考而对其消费和投资行为造成影响的一种认知偏差。大量研究表明,货币幻觉普遍存在于房地产投资、股票投资、组织管理以及捐赠等领域中。目前,研究者主要从决策框架、锚定与调整启发式、数目启发式以及神经心理机制这四个方面解释货币幻觉的形成机制。研究发现,货币幻觉的影响因素有心境、货币兑换率、通货膨胀率、情感依恋和先前经验。未来的研究可以从深入探讨货币幻觉的心理机制、影响因素和探索货币幻觉的应对策略这三个方面展开。     

Relevance of Context-bound loci to Topical Potential in the Argumentation Stage

In relation to the task of making an expedient selection from the available loci within the topical potential that strategic manoeuvring envisages for the argumentation stage, this paper proposes a version of topics, which is both inspired to the traditional doctrine of topics and consistent with the theoretical framing and the methodological tenets that are proper of modern semantics and current theory of argumentation. The argumentative relevance of communication context in its institutionalised and interpersonal components is brought to light. Three main aspects are focussed on: the strong synergy of the topical and the endoxical components in argument construction, the use of topics in analysis and evaluation of arguments and the heuristic function of topics in the production process. I express to Peter Houtlosser, Corina Andone, Sara Greco Morasso and Andrea Rocci my profound gratitude for their precious suggestions and cordial criticisms.

回忆准备就绪程度的判断准确性与记忆成绩的相关

本研究采用3×3×2三因素混合实验设计(年龄、材料、性别),以|P-A|÷A做指标,对回忆准备就绪程度的判断准确性与记忆成绩之间的相关进行了研究。发现回忆准备就绪程度的判断准确性与记忆成绩的相关为-0.6199,达到了0.01显著性水平。同时,年级越低,监测准确性与记忆成绩之间的相关越高。回忆准备就绪程度判断的准确性在三项材料上存在差异,说明不同难度的材料对记忆监测与记忆成绩之间的相关有影响。回忆准备就绪程度判断的准确性与记忆成绩的相关存在性别差异,男生的相关值比女生要高。
