Social cognitive predictors of college students’ academic performance and persistence: A meta-analytic path analysis

This study tested Social Cognitive Career Theory’s (SCCT) academic performance model using a two-stage approach that combined meta-analytic and structural equation modeling methodologies. Unbiased correlations obtained from a previously published meta-analysis [Robbins, S. B., Lauver, K., Le, H., Davis, D., & Langley, R. (2004). Do psychosocial and study skill factors predict college outcomes? A meta-analysis. Psychological Bulletin, 130, 261–288.] were used to create the input correlation matrices for subsequent path-analytic tests of the model, using both college GPA and retention as performance criteria. Results suggested that SCCT does an adequate to excellent job of modeling academic performance and persistence, but that model fit was better when general cognitive ability versus high school GPA was used to operationalize the ability/past performance variable. Results are discussed in terms of their fit with SCCT and their practical implications.     

空间能力测验及其研究应用

空间能力所表现出的个体差异一直是空间能力研究中的热点问题,在研究中所使用的测验也多种多样。二维空间能力测验主要包括标准心理旋转测验及其多种变式;三维空间能力测验则是运用虚拟现实技术针对动态空间定位与位置学习等空间能力开发出的新型测验。这些测验主要用于探讨空间能力个体差异的影响因素。本文在介绍测验的同时总结了空间能力个体差异研究的结果并提出展望。     

音乐能力测验:结构拓展与分析方式的转换

从测验结构上,一般音乐能力测验包含基本认知能力、审美能力和创造能力测验.而现代音乐能力测验延伸到奏唱能力、表演交流能力和个体特质测验,从结构上对其进行拓展和完善.另一方面,从分析方式上,教育测验从总结性评价朝形成性评价方向发展.以美国国家评价与教育计划(NAEP)为例对测验项目进行属性层面的分析,证明了音乐能力认知诊断测验(CDA)的可能性.未来的研究应注意音乐能力测验结构的完整性和系统性,并将音乐能力认知诊断测验应用到实际当中.     

多水平研究中的概念转换模式--以气氛研究为例

在组织环境中开展多水平研究会涉及到对处于组织中不同水平七的概念、变量或过程进行界定的问题。在已有概念基础上提出新的概念必须保证其有效性。本文以气氛研究为例介绍了与此问题相应的五种模式。     

工作记忆刷新训练改善抑郁倾向大学生情绪调节能力的HRV证据

根据流调中心用抑郁量表(CES-D)和贝克抑郁量表(BDI-II-C)的得分情况招募健康被试20例, 抑郁倾向被试40例, 以自愿参加的分组方式将抑郁倾向被试分为工作记忆刷新训练组和对照组, 每组20例。对训练组进行为期20天的工作记忆刷新训练, 对照组不做处理。记录各组被试在前后测的刷新功能以及在情绪调节任务中量表的得分情况, 并收集各组被试在5种实验条件下的心率变异性(HRV)的频域指标值, 结果发现：前测时抑郁倾向个体的HF-HRV显著低于健康个体的平均水平。经过工作记忆训练, 后测的抑郁倾向训练组在情绪调节任务中的HF-HRV水平有显著的提高, 贴近健康对照组的水平, 并与抑郁倾向对照组分离。研究表明, 工作记忆刷新训练能够使抑郁倾向大学生的HRV活动更接近健康被试的HRV活动, 表明抑郁倾向大学生的情绪调节能力得到了改善。     

The chronometry of mental ability: An event-related potential analysis of an auditory oddball discrimination task

The relation between intelligence and speed of auditory discrimination was investigated during an auditory oddball task with backward masking. In target discrimination conditions that varied in the interval between the target and the masking stimuli and in the tonal frequency of the target and masking stimuli, higher ability participants (HA) displayed more accurate discriminations, faster response time, larger P300 amplitude, and shorter P300 and mismatch negativity (MMN) latency than lower ability participants (LA). Task difficulty effects demonstrated with variation in mask type indicate that the mask does not interfere with the detection of the deviant target stimulus, but rather that the target and mask are integrated as a single compound stimulus. The temporal effects suggest that the speed of accessing short-term memory is faster for HA than LA and, on the basis of the MMN latency, the effect is accomplished automatically, without focused attention. Moreover, the pattern of results obtained with these data support the view that the accuracy effects are determined by processing speed rather than discrimination ability. Comparator models that accommodate these effects are discussed.     

Investigating the Impact of Noneffortful Responses on Individual-Level Scores: Can the Effort-Moderated IRT Model Serve as a Solution?

Suboptimal effort is a major threat to valid score-based inferences. While the effects of such behavior have been frequently examined in the context of mean group comparisons, minimal research has considered its effects on individual score use (e.g., identifying students for remediation). Focusing on the latter context, this study addressed two related questions via simulation and applied analyses. First, we investigated how much including noneffortful responses in scoring using a three-parameter logistic (3PL) model affects person parameter recovery and classification accuracy for noneffortful responders. Second, we explored whether improvements in these individual-level inferences were observed when employing the Effort Moderated IRT (EM-IRT) model under conditions in which its assumptions were met and violated. Results demonstrated that including 10% noneffortful responses in scoring led to average bias in ability estimates and misclassification rates by as much as 0.15 SDs and 7%, respectively. These results were mitigated when employing the EM-IRT model, particularly when model assumptions were met. However, once model assumptions were violated, the EM-IRT model’s performance deteriorated, though still outperforming the 3PL model. Thus, findings from this study show that (a) including noneffortful responses when using individual scores can lead to potential unfounded inferences and potential score misuse, and (b) the negative impact that noneffortful responding has on person ability estimates and classification accuracy can be mitigated by employing the EM-IRT model, particularly when its assumptions are met.     

中医事业发展路漫漫——纪念《山东省中医条例》颁布15周年

改革开放以来,中医药服务领域不断萎缩,中医药诊疗技术方法使用率低下,办医模式跟从西医院,备受质疑,这些问题的长期存在,表明中医事业发展之路依旧充满曲折,反思其中的原因,既有对《山东省中医条例》认识、落实不到位的问题,也有对中医药的作用、地位的认识脱离客观现实的问题,甚至错把规律当问题。保持中医教育、科研、临床各个环节的高度开放性对促进中医事业的健康发展十分重要。如不能在开放中将特色转化为现实优势,“特色”之路恐将越走越窄。
