班级环境如何影响受欺负者的适应？健康环境悖论及其发生机制

“健康环境悖论”是指在受欺负水平相对较低的环境中,受欺负个体有更多的适应问题。通过梳理相关实证研究,本文从人际与认知两大方面分析健康环境悖论的发生机制。人际机制强调健康环境会影响同伴群体对于受欺负者的态度和受欺负者的友谊,这些不良的人际关系进一步加剧受欺负者的适应困难。认知机制认为健康环境会通过向上的社会比较和消极归因方式,影响受欺负者的适应问题。最后,我们讨论了中国文化背景下“健康环境悖论”的适用性问题、未来研究的发展方向和对于干预实践的建议。     

Behavioural deficiencies of aggressive 8–9 year old boys: An observational study

The nature of aggressive boys' behaviour is examined. Pre-selected matched pairs of aggressive and control boys were observed in a naturalistic setting which facilitated comparison of the way in which recorded behaviours affected their respective peer relationships. A continuous commentary describing the child's interactions with others was recorded simultaneously with the child's speech during school play. These data were transcribed and coded according to activity, social participation, neighbours, and interactions. Individual behavioural items were grouped on the basis of their functional similarity. Marked differences were found between the two groups on certain categories, giving a clear indication of specific deficiencies in the behavioural repertoire of the aggressive boys.     

群体认同对群际敏感效应及其行为表现的影响

通过实验研究了群际互动中个体对不同来源身份的消极群体评价的情绪反应及群体认同的调节作用, 并从情绪-行为反应的连续性视角探索群际敏感效应的行为表现及内在机制。结果发现:(1)相比内群体的消极群体评价, 外群体的消极群体评价更能引起消极情绪反应; (2)群体认同对群际敏感效应起调节作用, 高群体认同者对来自外群体消极评价的情绪反应更加负面, 而低群体认同者这种趋势并不明显; (3)高群体认同者在经历外群体的消极群体评价后会表现出更多的内群体积极行为, 且消极情绪反应对此起中介作用。研究扩展了群际敏感效应的适用范围, 并为探讨其内部机制和后续影响提供了新的研究思路。     

来源记忆中背景的情绪效价与唤醒对提取过程的影响

以往研究表明情绪背景对来源记忆存在影响,但背景的情绪效价和唤醒如何影响熟悉性及回想尚存争议。本研究以ERPs技术作为测量手段,采用来源记忆多键范式,操纵背景的情绪效价及唤醒强度,以探讨编码阶段背景情绪影响来源记忆提取的认知神经机制。学习阶段,呈现中性汉字及情绪图片（正性高唤醒、正性低唤醒、负性高唤醒、负性低唤醒）;测验阶段,仅呈现汉字,被试进行五键判断。行为结果发现：来源正确的比率比来源错误的比率更高,反应时更短;同时提取正性背景的辨别力更强,反应时更短;提取高唤醒背景反应时更短。脑电结果发现了分别代表熟悉性及回想的FN400及LPC新旧效应,且在500～700 ms,提取正性背景及高唤醒背景诱发显著更正的ERPs,但效价与唤醒没有交互作用。总体来说,来源记忆中背景效价及唤醒度对回想过程存在独立影响,体现为正性背景及高唤醒背景对来源提取的促进作用。     

The relation between children's reading comprehension level and their comprehension of idioms

We report an investigation of 9-year-olds' ability to interpret idioms in relation to their reading comprehension level. We manipulated whether the idioms were transparent or opaque, whether they were real or novel, whether they were presented in isolation or in a supportive narrative context. As predicted, children were better able to explain the meanings of idioms in context than in isolation. The good and poor comprehenders did not differ in their abilities to interpret transparent idioms in context, but the poor comprehenders were significantly worse at using context to work out the meanings of opaque idioms. The explanation task revealed the source of information used by the children to derive nontarget interpretations. We discuss these findings in relation to idiom processing strategies and Levorato and Cacciari's global elaboration model.     

Getting the Big Picture in Community Science: Methods That Capture Context

Community science has a rich tradition of using theories and research designs that are consistent with its core value of contextualism. However, a survey of empirical articles published in the American Journal of Community Psychology shows that community scientists utilize a narrow range of statistical tools that are not well suited to assess contextual data. Multilevel modeling, geographic information systems (GIS), social network analysis, and cluster analysis are recommended as useful tools to address contextual questions in community science. An argument for increased methodological consilience is presented, where community scientists are encouraged to adopt statistical methodology that is capable of modeling a greater proportion of the data than is typical with traditional methods.     

Processing homonymy and polysemy: effects of sentential context and time-course following unilateral brain damage

The present study investigated the abilities of left-hemisphere-damaged (LHD) non-fluent aphasic, right-hemisphere-damaged (RHD), and normal control individuals to access, in sentential biasing contexts, the multiple meanings of three types of ambiguous words, namely homonyms (e.g., "punch"), metonymies (e.g., "rabbit"), and metaphors (e.g., "star"). Furthermore, the predictions of the "suppression deficit" and "coarse semantic coding" hypotheses, which have been proposed to account for RH language function/dysfunction, were tested. Using an auditory semantic priming paradigm, ambiguous words were incorporated in dominant- or subordinate-biasing sentence-primes followed after a short (100 ms) or long (1,000 ms) interstimulus interval (ISI) by dominant-meaning-related, subordinate-meaning-related or unrelated target words. For all three types of ambiguous words, both the effects of context and ISI were obvious in the performance of normal control subjects, who showed multiple meaning activation at the short ISI, but eventually, at the long ISI, contextually appropriate meaning selection. Largely similar performance was exhibited by the LHD non-fluent aphasic patients as well. In contrast, RHD patients showed limited effects of context, and no effects of the time-course of processing. In addition, although homonymous and metonymous words showed similar patterns of activation (i.e., both meanings were activated at both ISIs), RHD patients had difficulties activating the subordinate meanings of metaphors, suggesting a selective problem with figurative meanings. Although the present findings do not provide strong support for either the "coarse semantic coding" or the "suppression deficit" hypotheses, they are viewed as being more consistent with the latter, according to which RH damage leads to deficits suppressing alternative meanings of ambiguous words that become incompatible with the context.     

Indian Women’s Experience of a Narrative Intervention Using Art And Writing*

International and minority populations tend to underutilize mental health services, including marriage and family therapy. Models of marriage and family therapy developed in the West may reflect Western values and norms inappropriate for diverse cultural contexts. This article presents an exploratory, qualitative study of a narrative therapy approach with Asian Indian women. This study adds to the small body of narrative-based empirical studies, and has a unique focus on intercultural applications and the experience of participants. Participant experience was examined along four phenomenological dimensions. Findings indicate the suitability of narrative interventions and nontraditional treatment delivery for this population.*This research was presented in 2004 at the annual conference of the American Association for Marriage and Family Therapy.     

Preference for human direct gaze in infant chimpanzees (Pan troglodytes)

We studied gaze perception in three infant chimpanzees (Pan troglodytes), aged 10-32 weeks, using a two-choice preferential-looking paradigm. The infants were presented with two photographs of a human face: (a) with the eyes open or closed, and (b) with a direct or an averted gaze. We found that the chimpanzees preferred looking at the direct-gaze face. However, in the context of scrambled faces, the infants showed no difference in gaze discrimination between direct and averted gazes. These findings suggest that gaze perception by chimpanzees may be influenced by the surrounding facial context. The relationship between gaze perception, face processing, and the adaptive significance of gaze perception are discussed from an evolutionary perspective.     

Confidence judgments in event recall: developmental progression in the impact of question format

Two studies were conducted to examine developmental progression in children's and adults' ability to adequately monitor their own attempts to recall event details as well as the dependence of such metamemorial competencies on question formats. Eight and 10-year-old children as well as adults (Study 1, N=116; Study 2, N=60) rated their confidence when responding to specific questions about an observed event. Confirming most recent results, children and adults gave higher confidence ratings after correct than after incorrect answers. This ability, however, was limited to an unbiased question format. When being asked misleading questions, children's ability to differentiate was undermined, as reflected in equally high confidence judgments after correct and incorrect answers, even when the interview contained a mix of misleading and unbiased questions. When the interviewer "bombarded" the children with an uninterrupted series of misleading questions, children's difficulties appeared to be even more pronounced. These findings highlight the importance of the way in which questions are asked, and point to age-related progression in the relative impact of questioning style.
