家长投入对子女学业成绩的影响：有调节的中介模型

本研究测评了广州市1628名六年级学生的学习投入和学业成绩,并调查了其家长的家长投入和教养风格。结果发现：（1）家长投入能正向预测子女的学业成绩;（2）在家长投入与子女学业成绩的关系之间,子女的学习投入起完全中介作用;（3）家长教养风格对家长投入与子女学习投入的关系路径起调节作用,积极的教养风格有利于促进家长投入对子女学习投入的正向影响。结果表明：积极的家长教养风格能促进家长投入转化为子女的学习投入,进而促使子女学业成绩的提升。     

Standard Errors of Kernel Equating: Accounting for Bandwidth Estimation

In standardized testing, equating is used to ensure comparability of test scores across multiple test administrations. One equipercentile observed-score equating method is kernel equating, where an essential step is to obtain continuous approximations to the discrete score distributions by applying a kernel with a smoothing bandwidth parameter. When estimating the bandwidth, additional variability is introduced which is currently not accounted for when calculating the standard errors of equating. This poses a threat to the accuracy of the standard errors of equating. In this study, the asymptotic variance of the bandwidth parameter estimator is derived and a modified method for calculating the standard error of equating that accounts for the bandwidth estimation variability is introduced for the equivalent groups design. A simulation study is used to verify the derivations and confirm the accuracy of the modified method across several sample sizes and test lengths as compared to the existing method and the Monte Carlo standard error of equating estimates. The results show that the modified standard errors of equating are accurate under the considered conditions. Furthermore, the modified and the existing methods produce similar results which suggest that the bandwidth variability impact on the standard error of equating is minimal.     

Prospective prediction of academic performance in college using self- and informant-rated personality traits

Five-factor personality ratings were provided by undergraduate freshmen, their parents, and their college peers as predictors of cumulative GPA upon graduation. Conscientiousness ratings were significant predictors of GPA by all three raters; peer ratings of Conscientiousness were the only significant predictor of GPA when self-, parent-, and peer-ratings of Conscientiousness were examined simultaneously. College major was a moderator of this relationship, with self- and parent-ratings of Conscientiousness correlating more strongly with GPA among Social Science majors and parent-ratings of Conscientiousness correlating less strongly with GPA among Science majors. These findings replicate existing research regarding the validity of informant ratings as predictors of behavioral outcomes such as academic performance, while emphasizing the importance of including multiple informants from various life contexts.     

道德情绪:探寻道德与创造力关系的新视角

先前有关道德与创造力的关系研究多关注道德的认知与行为差异对创造力产生的影响, 但研究结果却存在较大的分歧。为此, 研究从道德情绪的视角, 对二者的关系进行了系统地梳理, 发现道德情绪存在: 以情绪效价调节创造性认知; 激发道德动机, 中介人格与创造力的关系; 引发自我觉察, 促进顿悟与创造性成就的产生; 提升心理资本, 影响不同创造力特性的表达等, 多种影响个体创造力的路径。这表明, 与道德认知和行为相比, 道德情绪不仅能更加全面准确地体现出个体实际的道德活动、促进符合道德标准的创造力产生; 还为人们解释道德与创造力的关系提供了多样的路径与可能。未来需继续加深对道德情绪及其内在机制的理解、通过系统性地选取创造性任务, 明确道德情绪、道德与创造力之间的关系, 寻找道德培养与创造力激发的新模式。     

Study strategies and beliefs about learning as a function of academic achievement and achievement goals

Prior research by Hartwig and Dunlosky [(2012). Study strategies of college students: Are self-testing and scheduling related to achievement? Psychonomic Bulletin &; Review, 19(1), 126–134] has demonstrated that beliefs about learning and study strategies endorsed by students are related to academic achievement: higher performing students tend to choose more effective study strategies and are more aware of the benefits of self-testing. We examined whether students’ achievement goals, independent of academic achievement, predicted beliefs about learning and endorsement of study strategies. We administered Hartwig and Dunlosky’s survey, along with the Achievement Goals Questionnaire [Elliot, A. J., &; McGregor, H. A. (2001). A 2 × 2 achievement goal framework. Journal of Personality &; Social Psychology, 80, 501–519] to a large undergraduate biology course. Similar to results by Hartwig and Dunlosky, we found that high-performing students (relative to low-performing students) were more likely to endorse self-testing, less likely to cram, and more likely to plan a study schedule ahead of time. Independent of achievement, however, achievement goals were stronger predictors of certain study behaviours. In particular, avoidance goals (e.g., fear of failure) coincided with increased use of cramming and the tendency to be driven by impending deadlines. Results suggest that individual differences in student achievement, as well as the underlying reasons for achievement, are important predictors of students’ approaches to studying.     

中学生家庭社会经济地位与学业成绩的关系:心理素质各维度的多重中介作用分析

研究用方便抽样的方法调查了1570名中学生,通过中学生心理素质问卷来测量其心理素质,并对被试进行家庭社会经济地位（Socioeconomic Status,SES）评估和学业成绩考察。结果表明：（1）除中学生家庭SES与学业成绩相关不显著外,其余变量呈两两正相关;（2）整体心理素质在中学生家庭SES和学业成绩间中介作用显著。（3）认知特性和适应能力在家庭SES和学业成绩间存在多重中介作用,但两者存在抵消抑制作用。据此得出结论,高家庭SES对中学生学业成绩的积极影响,主要是通过对其认知特性的提升来实现的,而同时适应能力的增强则对学业成绩的上升有抑制作用。这一发现不仅拓展了对家庭投资理论和家庭压力模型的认识,还为进一步深化心理素质研究提供了新的思路;同时,该结论表明应为低家庭SES的学生提供补偿性教育,重视其认知特性的培养和提高,从而有助于提升其学业成绩水平。     

学生感知的学校氛围与主客观学业成绩:心理素质及其分维度的中介作用

本研究旨在探究心理素质及其分维度在学生感知的学校氛围与主客观学业成绩之间的中介作用。采用整群抽样的方法选取被试,样本一抽取北京、陕西等七个省市10所中学7~12年级共1274名学生,样本二抽取重庆、湖南等四个省市7所中学7~12年级共2190名学生。结果表明：（1）学生感知的学校氛围与主观学业成绩存在显著正相关,与客观成绩的正相关呈边缘显著,与心理素质存在显著正相关;（2）心理素质在感知的学校氛围与主客观学业成绩之间中介作用显著;（3）心理素质的不同维度在学生感知的学校氛围与学业成绩关系之间中介作用存在差异,其中认知品质在学生感知的学校氛围与学业成绩之间存在稳定的正向中介作用。研究结果启示教育者在实施素质教育的过程中,应注意营造积极的学校氛围,以此提高学生心理素质,尤其是认知品质的发展,从而提高学生的学业成绩。     

Using Curriculum-Based Measurement to Evaluate Intervention Efficacy

SUMMARY

The use of Curriculum-Based Measurement for evaluating treatment efficacy is described and discussed. The basic methods and applications of Curriculum-Based Measurement are described, followed by examples of its application in two intervention program evaluation projects. The first project involved one individual student experiencing academic difficulties. The second project focused on evaluating a reading instruction program for a group of students. In both examples, the use of Curriculum-Based Measurement contributed significantly to monitoring student progress in response to educational program variables and making treatment evaluation decisions.     

Social relationships,stressful life events,and self-reported physical health: Genetic and environmental influences

Abstract

This study investigates how the associations between self-reported health, stressful life events, and social relationships are mediated by genetic and environmental influences and how much of the variance in health is in common with variation in these psychosocial factors. The analyses are based on questionnaire data from 576 pairs of twins reared apart and twins reared together. The data revealed that for men environmental influences were solely important for variation in the psychosocial measures and were the primary mediators of the relationship with health. For women, on the other hand, a substantial portion of the variance in the psychosocial factors was due to genetic influences and these influences also contributed to the bulk of the correlations with health. The gender differences for the relationships and their mediation indicate that what should be regarded as a psychosocial factor of importance for health might differ between genders.     

The effects of stress on dna repair capacity

Abstract

Research has shown that lymphocytes of high-distress patients have reduced DNA repair relative to that of low-distress patients and healthy controls. Furthermore, deficits in repair are associated with an increased risk of cancer. Using and academic stress model, we hypothesized that students would exhibit lower levels of Nucleotide Excision Repair (NER) during a stressful exam period when compared to a lower stress period. Participants were 19 healthy graduate level students. NER was measured in lymphocytes using the unscheduled DNA synthesis (UDS) assay with slide autoradiography. Contrary to prediction, mean values for NER significantly increased during the higher stress period relative to the lower stress period controlling for background differences in repair. Furthermore, lymphocytes had significantly increased repair of endogenous damage during the higher stress period. Stress appears to directly increase DNA repair. Additionally, stress may increase DNA repair indirectly by increasing damage to DNA.
