集体问题解决中的认知表征、行为惯例和动态能力

以王建安和张钢(2008)开发的三人TTT纸牌游戏(原游戏)及其变式(变式游戏)为实验任务, 研究了集体问解决中认知表征和行为惯例对提高动态能力的作用。共有240名被试, 分成80个三人小组, 参加了前后两场各20盘游戏。80个小组按照是否被告知游戏的问题表征(即有无认知表征), 以及是玩原游戏还是玩变式游戏, 均分成4个区组来玩第一场游戏。在第二场游戏中, 4个区组都玩变式游戏。以玩每盘游戏的平均步时和在问题表征中走过的路径为指标测量惯例, 以玩第一场原游戏习得的能力向玩第二场变式游戏的迁移率来衡量动态能力。结果发现：一方面, 适当的认知表征有助于提高集体问题解决的动态能力; 另一方面, 没有适当认知表征支持的行为惯例反而会阻碍动态能力的发展。概括地说, 动态能力的决定因素是认知表征而不是行为惯例。     

青少年和母亲知觉的差异及其与青少年问题行为的关系

从辽宁辽阳市选取605名小学五年级至初中二年级、高中一年级至高中三年级学生及其母亲为被试,探讨青少年与其母亲对父母冲突知觉的差异,以及这种知觉差异与青少年问题行为的关系。要求青少年和其母亲分别报告父母过去一年中在10个方面的冲突频率,同时要求青少年报告自己在过去一年中20种问题行为的发生频率。研究发现：青少年对父母冲突的知觉明显比母亲消极,但是到了高中．两者知觉的差异不再明显;青少年与母亲在指向父母自身冲突方面的知觉差异大于指向孩子的父母冲突方面两者的知觉差异;青少年知觉到的父母冲突多于母亲知觉到的父母冲突的人数比例高于青少年知觉到的父母冲突少于母亲知觉到的父母冲突的人数比例;青少年与母亲对父母冲突知觉的差异会增加青少年出现问题行为的可能性。     

成年人现实生活问题解决的年龄差异

采用自行编制的十个与现实生活有关的问题,对２０至８５岁的成年人,分成青年至老老年四个年龄组进行测验,试图探讨成年人现实生活问题解决的年龄差异;并同时进行２０个问题（简称猜图）作业的实验,以期对比研究。结果看到：（１）两组主试对现实生活问题解决的评分一致率合格（ｒ值均在０．７４以上）。（２）对现实生活问题解决提出方案的数量（Ｎ）,三个较年轻组比老老年组答案多些;解决问题有效最高分（Ｈ）和各方案的平均     

假设检验思维过程中的启发式策略研究

本研究运用自编的一个关于规则发现的计算机程序研究了大学生问题解决过程中形成假设、设计实验、实施检验三个阶段上的“假设———检验”的思维过程。结果发现,规则差别对规则发现有显著影响,反馈方式在本实验条件下没有主效应,启发式是假设检验过程中的重要思维策略     

A Statistical Hypothesis Testing Method for the Rank Ordering of the Priorities of the Alternatives in the Analytic Hierarchy Process

In analytic hierarchy process (AHP), a ratio scale (π₁, π₂, ⋯, π_t) for the priorities of the alternatives {T₁, T₂, ⋯, T_t} is used for a decision problem in which π_i/π_j is used to quantify the ratio of the priority of T_i to that of T_j. In a group decision‐making setup, the subjective estimates of π_i/π_j are obtained as entries of a pairwise comparison matrix for each member of the group. On the basis of these pairwise comparison matrices, one of the topics of interest in some situation is the total rank ordering of the priorities of the alternatives. In this article, a statistical method is proposed for testing a specific total rank ordering of the priorities of the alternatives. The method developed is then illustrated using numerical examples.

Why Does Frustration Predict Psychopathology? Multiple Prospective Pathways Over Adolescence: A TRAILS Study

Adolescents' temperamental frustration is a developmental precursor of adult neuroticism and psychopathology. Because the mechanisms that underlie the prospective association between adolescents' high frustration and psychopathology (internalizing/externalizing) have not been studied extensively, we quantified three pathways: stress generation [mediation via selection/evocation of stressful life events (SLEs)], cross‐sectional frustration‐psychopathology overlap (‘carry‐over’/common causes), and a direct (non‐mediated) vulnerability effect of frustration, including moderation of SLE impact. Frustration and psychopathology were assessed at age 16 with the Early Adolescent Temperament Questionnaire and the Youth Self‐Report. No gender differences in frustration were observed. At age 19, psychopathology was reassessed by using the Adult Self‐Report, while occurrence of endogenous (self‐generated) and exogenous (not self‐generated) SLEs during the interval (ages 16–19) were ascertained with the Life Stress Interview, an investigator‐based contextual‐stressfulness rating procedure (N = 957). Half of the prospective effect of frustration on psychopathology was explained by baseline overlap, including effects of ‘carry‐over’ and common causes, about 5% reflected stress generation (a ‘vicious’ cycle with the environment adolescents navigate and shape), and 45% reflected unmediated association: a direct vulnerability effect including stress sensitivity or moderation of SLE impact. After adjustment for their overlap, frustration predicted the development of externalizing but not internalizing symptoms. Copyright © 2016 European Association of Personality Psychology     

阅读理解情境下中学生提问能力发展特点研究

从北京市一所普通中学四个年级随机选取学生169名为被试,采用开放式问卷法研究了学生在阅读理解背景下提问能力的发展特点,结果发现:(1)学生提问的频次变化范围较广,随着提问频次的增加,人数呈现波浪式下降趋势;(2)学生所提问题被分为三种水平:事实性问题,推论性问题和评价性问题;(3)随着年级的上升,学生提问水平逐渐增高;(4)学生提问性别差异显著,尤其是在高水平问题上,女生提问数量多于男生。     

儿童4岁时的自我控制对其7岁及11岁社会适应的预测

采用追踪设计,考察了138名儿童4岁时的自我控制对其7-11岁期间社会适应的影响。分别采用实验室观察法和问卷法测量了儿童的自我控制与社会适应。研究结果表明（1）儿童4岁时的自我控制存在显著的性别差异,其中女孩的自我控制水平显著高于男孩;（2）4岁时的自我控制能够显著负向预测7岁时母亲报告的外显和内隐问题行为,以及父亲报告的外显问题行为;（3）4岁时的自我控制能够显著负向预测7岁时教师评价的学习问题行为;（4）4岁时的自我控制能够显著负向预测11岁时父亲报告的外显问题行为;（5）4岁时的自我控制能够显著正向预测教师报告的挫折耐受能力。     

A multicomponent approach to thinning reinforcer delivery during noncontingent reinforcement schedules

We evaluated a noncontingent reinforcement procedure that involved initially providing three subjects with signaled, continuous access to the functional reinforcer for aggression and slowly increasing the amount of time subjects were exposed to the signaled unavailability of the reinforcer. Additionally, alternative potential reinforcers were available throughout the sessions. Results showed immediate and substantial reductions in aggression for all three subjects. The clinical utility of this intervention is discussed, and future research directions are recommended.
