在抑制分心物干扰效应上学困生和学优生的比较

采用Stroop颜色命名作业,在严格控制各种条件下探究重复分心物的促进效应是由习惯化机制还是由分心物连续抑制机制造成的问题,进而比较学困生和学优生在Stroop干扰效应、重复分心物促进效应和负启动效应上的差异,结果显示,重复分心物促进效应是由习惯化机制造成的。这种抑制机制,只有在分心物重复条件下才能发挥作用;因而其效用并不广泛;而负启动效应所指的分心物抑制机制却是一种效用广泛的抑制机制。并进而揭示,学困生和学优生都存在重复分心物促进效应,但因学困生的负启动效应比学优生小,所以学困生在Stroop色词干扰效应上大于学优生。     

Long-term consequences of childhood physical and psychological maltreatment

This study assessed whether some of the correlates of learned helplessness—depression, low self-esteem, and a maladaptive attributional style—are long-term consequences of child abused. In this study, 260 subjects were identified as physically abused, psychologically abused, both physically and psychologically abused, or nonabused, based on responses to the Child Abuse Questionnaire (CAQ). Subjects were tested for levels of nonclinical depression via the Beck Depression Inventory (BDI), for levels of self-esteem via the Rosenberg Self-Esteem Scale (RSE), and for the adaptiveness of attributional style via the Attributional Style Questionnaire (ASQ). It was hypothesized that each of the three abuse groups would differ from the control group on the three dependent measures; differences among the three abuse groups were also explored. Three one-way analyses of variance indicated that (1) BDI scores reflected a greater tendency toward depression in subjects reporting both types of abuse than in nonabused subjects or in subjects reporting either psychological or physical abuse, (2) subjects reporting psychological abuse only or both psychological and physical abuse showed lower self-esteem than did nonabused subjects, and (3) abused subjects did not seem to exhibit a more maladaptive attributional style than that of nonabused subjects. In addition, multiple linear regression analyses pointed to psychological abuse as a critical variable in predicting levels of depression, self-esteem, and attributional style, when physical abuse effects were controlled. Controlling for the effects of psychological abuse, however, indicated that physical abuse did not significantly contribute to the variance in these variables. Implications for the learned helplessness model and for future research are discussed. © 1992 Wiley-Liss, Inc.     

Molecular (moment-to-moment) and molar (aggregate) analyses of behavior

Ten meanings or usages of the terms molecular and molar analyses are based on (1) numbers of responses, (2) durations of activities, (3) levels, (4) scales, (5) contiguity versus correlation, (6) behavioral standards, (7) function with or without structure, (8) local versus global phenomena, and (9) control by shaping of sequential moment-to-moment behavior. These usages reveal divisive viewpoints along with ambiguities in the Law of Effect, the definition of an operant, response strength, response probability, random behavior, time allocation, shaping, controlled versus uncontrolled operants, and roles for ordinary language. Usage 10 is less divisive and combines, and in that sense unifies, molecular behavior, defined as shaped moment-to-moment sequential behaving, and molar, defined as averages of aggregates of those shaped responses. It combines shaping, that establishes and changes operant behaviors, and strengthening that changes the amounts of those shaped behaviors. I conclude that general behavioral theory will combine strengthening with such methods as parametric, hybrid, or nonparametric shaping, and will use computational methods to simulate moment-to-moment behavior streams from which any aggregates of theoretical interest may be computed. Such a synthesis may not require different levels, scales, or new scientific paradigms.     

同事公正氛围：构念、测量、效能与展望

以往对公正氛围的探讨主要集中于源自权威的公正氛围上,而对来自同事的公正氛围关注较少。同事公正氛围是指团队成员对团队内同事之间相互对待公正性的共同知觉。本文首先对比总结界定了同事公正氛围的概念,明晰了其结构维度与测量工具,然后着重梳理评价了同事公正氛围的影响效能。未来研究应致力于：加强探讨同事公正氛围的前因变量,探讨同事公正氛围影响效能的内在机制和边界条件,运用纵向设计研究同事公正氛围的形成机制及影响效能,以及探索同事公正氛围研究的本土化。     

积极刻板印象会产生消极影响?

积极刻板印象是对社会群体的积极特质的描述, 以往刻板印象的相关研究主要聚焦于消极刻板印象, 却忽略了对积极刻板印象尤其是其消极影响的探讨。基于此, 分别从种族、性别和年龄这三个方面详细梳理了积极刻板印象的积极影响和消极影响, 并阐述了其产生的条件, 包括积极刻板印象的微妙激活和明显激活、积极刻板印象的准确表述和极端表述、积极刻板印象阐述者的内外群身份、呈现积极刻板印象的文化背景等。未来研究可从集体主义文化、研究领域和对象, 干预方法和消极刻板印象的积极影响等方面进一步探讨。     

高低阅读技能聋生词汇加工的语境预测性效应特点:眼动证据

本研究考察中文聋生读者利用语境预测性信息促进词汇加工的过程特点。实验采用3（组别：高阅读技能聋生组vs.高阅读技能聋生的能力匹配健听组vs.低阅读技能聋生组）×2（句子背景对目标词的预测程度：高预测vs.低预测）混合设计。结果发现：（1）目标词的左侧词汇上,能力匹配健听组在凝视时间和总注视时间两个指标上可见语境预测性效应,两个聋生组在任何指标上均没有语境预测性效应;（2）目标词上,能力匹配健听组在首次注视时间、凝视时间和总注视时间三项指标上均可见显著的语境预测性效应,高阅读技能聋生组仅在总注视上可见语境预测性效应,低阅读技能聋生的任何眼动指标均没有语境预测性效应。由此可见,聋生在利用语境预测性促进词汇加工方面与健听读者有所差异;相对于低阅读技能聋生,高阅读技能聋生读者识别词汇时能更多地利用语境预测性信息。     

Social comparisons and quality of life among survivors of childhood cancer and their mothers

Abstract

Sixty-three survivors of childhood cancer (mean age 17 years), currently well and off-treatment, and their mothers were interviewed individually about their experiences and the impact of their illness on their lives. Survivors also completed four questionnaire measures of different aspects of quality of life (perceptions of illness experience, future worries, health problems and body image satisfaction), whereas mothers recorded their perceptions of their child's quality of life on the same four scales. These scales showed good internal consistency and convergent validity for both survivors and mothers. Mothers also completed a measure of their own quality of life (the SF-36). The interviews with both survivors and mothers were content-analysed for statements expressing social comparisons. These statements were coded according to whether the comparison implied a favourable, neutral or unfavourable evaluation of the individual survivor. Mothers who made a higher proportion of unfavourable comparisons reported worse adjustment for their child on all four scales and described their own quality of life more negatively. Among survivors, those who made a higher proportion of unfavourable comparisons gave significantly more negative self-ratings on one of the four scales. Correlations between survivors' and mothers' ratings on the four scales were positive, but comparatively low. This reinforces concerns about using parents as proxy judges of young people's quality of life, although the correlations were more satisfactory in the case of younger rather than older (>18.5 years) survivors. Mothers who rated their own quality of life as less satisfactory reported more problems for their child on all four scales, irrespective of how the survivors described themselves.
