经验、材料性质及加工水平对虚假记忆的影响

本实验采用DRM研究范式,考察经验、材料性质和加工水平三个方面对虚假记忆的影响。实验首次采用句子的方式呈现,给被试提供符合经验和不符合经验的句子进行学习和再认。实验结果显示,三个因素对虚假记忆的影响都是显著的,其中,经验是导致虚假记忆产生的主导因素,加工深度同经验之间以及材料性质同经验之间的交互作用均存在显著的交互作用。     

学生提问与语文阅读理解能力的关系研究

随机选取北京市某中学初一-高二学生169名,以问卷法研究了他们对文章的提问能力与其阅读理解能力的关系,结果发现:(1)学生提问频次变化范围较广,不同水平提问数量存在显著的差异;(2)从分水平的角度来看,被试个体提问最高频次和总频次,由多到少都呈现出第二、第三、第一水平的顺序;(3)学生第三水平提问总数对第二水平阅读理解能力有显著预测作用;(4)学生第三水平提问总数对第三水平阅读理解能力有一定的显著预测作用。     

Antecedents of mentoring support: a meta-analysis of individual,relational, and structural or organizational factors

The value of mentoring is growing substantially as organizations take a renewed interest in employee development to better survive in the dynamic and competitive market today. In the wake of this renewed interest, this meta-analysis was conducted to quantitatively review the multi-level antecedents (e.g., individual, relational, and structural/organizational) of different kinds of mentoring support (e.g., career, psychosocial, role modeling) in organizational settings and to revisit the theoretical underpinnings of each antecedent. Results indicated some key antecedents of mentoring support at individual (e.g., protégé's proactivity, protégé's learning goal orientation, mentor's transformational leadership), relational (e.g., affect based trust, perceived similarity), and structural/organizational levels (e.g., organizational support for mentoring, supervisory mentoring). Recommendations for future research and organizational practice of mentoring are presented.     

Complexity effects on the children's gambling task

The children's gambling task (CGT [Kerr, A., & Zelazo, P. D. (2004). Development of “Hot” executive function: The children's gambling task. Brain and Cognition, 55, 148–157]) involves integrating information about losses and gains to maximize winnings when selecting cards from two decks. Both cognitive complexity and control (CCC) theory and relational complexity (RC) theory attribute younger children's difficulty to task complexity. In CCC theory, identification of the advantageous deck requires formulation of a higher-order rule so that gains and losses can be considered in contradistinction. According to RC theory, it entails processing the ternary relation linking three variables (deck, magnitude of gain, magnitude of loss). We designed two less complex binary-relational versions in which either loss or gain varied across decks, with the other held constant. The three closely matched versions were administered to 3–5-year-olds. Consistent with complexity explanations, children in all age groups selected cards from the advantageous deck in the binary-relational versions, but only 5-year-olds did so on the ternary-relational CGT.     

Aging, Executive Functioning, and Social Control

ABSTRACT— Aging is associated with atrophy of the frontal lobes of the brain, which are the seat of executive functions. Because successful social functioning often requires executive control, aging can lead to unintended social changes via deficits in executive control. In this article I review evidence that, due to losses in executive control, aging leads to increased prejudice and social inappropriateness and, under certain circumstances, increased depression and problem gambling. I then discuss theory and research suggesting possible interventions that might ameliorate unwanted social changes brought about by executive decline.     

Working memory deficit in children with mathematical difficulties: a general or specific deficit?

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both mathematical and reading difficulties were compared with 47 age-matched and 50 younger controls (9-year-olds) on a number of working memory tasks. Compared with the age-matched controls, both groups of children with MDs performed worse on tasks tapping the central executive (e.g., visual matrix span) and the phonological loop (e.g., word span). More important, the MD group performed worse than the younger controls on the counting span task, whereas the group with comorbid mathematical and reading difficulties performed worse on the counting span task and the visual matrix span task. These findings provide support for the assumption that children with MDs have a working memory deficit. More specifically, children with MDs have a central executive deficit connected to concurrent processing and storage of numerical and visual information.

通过千余份问卷调查研究,透视出医学生对医事法律认知程度普遍偏低的状况,进而从医学院教育方针,以及医学生法律意识、自我教育能力等方面,分析、探究原因,寻求改进医事法学教育滞后问题,加速培养学医懂法医学人才的途径与方法。     

大学生合作学习的问题解决过程及其对问题解决水平的影响

以认知风格为依据,将合作学习小组分为场依存同质组、场独立同质组以及异质组。通过小组对开放问题以及逻辑问题的解决,考察不同认知风格个体、不同类型小组的问题解决过程。同时考察问题解决过程对问题解决水平的影响。结果表明：（1）个体在解决不同类型问题时的过程体验不同。（2）问题解决过程在个体的认知风格和逻辑问题解决水平之间起调节作用。（3）不同类型小组的问题解决过程不同。（4）合作是影响小组合作学习效果的重要因素之一。     

任务切换机制研究的理论争议与整合

任务切换是执行控制的一种重要功能。切换代价是量化执行控制持续时间的指标。并广泛应用于各个研究领域。但是切换代价在多大程度上体现了执行控制的作用,仍然还存在争论．当前主要存在任务设置重构、任务设置惯性和联结竞争三种理论。本文首先介绍了三种理论的基本观点和实验证据,以及对任务切换加工机制的分析;其次阐明了对三种理论进行整合的相关研究;最后分析了进一步研究的方向。
