情境对“热情优先效应”的影响——基于同伴提名法的检验

本研究同时从热情和能力维度独立和互依视角,采用同伴提名法考察社交与工作导向情境对“热情优先效应”的增强与削弱作用。结果发现：（1）社交导向情境下表现出明显的“热情优先效应”;（2）工作导向情境对能力的突显效应与“热情优先效应”的表现相反：在热情与能力独立视角下,情境的削弱效应使得“热情优先效应”无法表现;而在热情与能力互依视角下,“热情优先效应”则强于情境对其的削弱效应。     

Self-regulation foci and mood affect healthy and unhealthy eating behaviours differently in successful weight-loss treatment participants

An increased understanding of how self-regulation and mood affects both healthy and unhealthy eating behaviours is required to improve weight-loss intervention architectures. Women with obesity (N = 54, M_BMI = 34.80 kg/m²), who obtained ≥5% weight loss over 12 months (M = −9.01 kg) within a community-based behavioural weight-loss treatment, were assessed. Improvements in exercise- and eating-focused self-regulation (over 3 and 6 months), and the consumption of fruits/vegetables and sweets (over 6 and 12 months), were each significant. Multiple regression analyses indicated that changes in (a) aggregated (exercise-focused + eating-focused) self-regulation, (b) eating-focused self-regulation alone and (c) eating self-regulation that carried over from exercise-focused self-regulation, each significantly predicted fruit/vegetable consumption changes (R² = .15–.28). Entry of overall mood did not significantly increase those models' predictive strength. Conversely, mood was the most salient predictor of change in sweets intake. There were significant inverse relationships between changes in fruits/vegetables and sweets consumption. Implications for self-regulation theory and treatment improvements were suggested.     

Resurgence of previously taught academic responses

Resurgence is often discussed in relation to the relapse of undesirable behavior. However, resurgence may also describe the recurrence of socially appropriate behavior, including academic responding. The recurrence of academic responses following periods of extinction may aid in the solution of novel problems. The aims of this study were to evaluate the resurgence of complex, desirable behavior related to college-level instruction and to explore problem form as an aspect of environmental context. Each participant was taught 2 response chains to solve quadratic equations across experimental phases, followed by a phase in which neither chain resulted in the correct solution (extinction). During Experiment 1, the equations presented during extinction resembled those presented during reinforcement of the alternative response. Of the 8 participants in Experiment 1, 4 attempted to use the first-taught chain to solve an equation in the extinction phase. During Experiment 2, the equations presented during extinction resembled those presented during reinforcement of the target response. Of the 8 participants in Experiment 2, 6 attempted to use the first-taught chain to solve an equation in the extinction phase. Results demonstrate the resurgence of academic responses and suggest that the form of the problem may constitute a context that affects resurgence.     

Framing Political Risks: Individual Differences and Loss Aversion in Personal and Political Situations

People are motivated to avoid losses. In the context of politics, studies consistently show that the threat of losses increases support for risky public policies more than the promise of gains. Here, we predict that this loss aversion is calibrated by individual differences related to one’s ability to accommodate resource loss, and we investigate how these individual differences moderate reactions to the threat of losses and the promise of gains. Results from large-N experiments consistently demonstrate that this moderation effect crucially depends on whether the resource loss relates to oneself or one’s group—whether the setting is personal or political. Consistent with classic assumptions, individuals with inferior abilities to cope with resource loss are more loss averse in personal settings. In political settings where group resources are threatened, effects reverse: Individuals with superior resources and a more central position within the group consistently respond more to the prospect of loss. As discussed, these findings have important implications for our understanding of why and for whom the threat of loss motivates risky personal and political choices. By consequence, the findings also shed novel light on the psychological underpinnings of recent risky political events.      

Influence of contextual information on observers' perceptions of actors' intentions to harm others

Previous examinations of perceptions of aggressive behaviors have used static stimulus presentations (e.g., photographs or slides). This investigation examined the impact of varying amounts of geographical and temporal contextual information on observers' perceptions of actors' intentions to physically and psychologically (intimidate) harm others. Participants (51 elite ice hockey players) were randomly assigned to view one of three video-taped presentations showing eight ice hockey behaviors in either a) a dynamic mode with contextual information, b) a dynamic mode with no context, or c) a static, “freeze-frame” mode. MANOVA results showed that non-aggressive stimuli were perceived as less aggressive, and aggressive stimuli were perceived as more aggressive in dynamic presentations with context than in static presentations. Based on these findings, it is suggested that future research focussing on perceptions of aggressive behavior utilize a dynamic stimulus presentation containing context material. © 1996 Wiley-Liss, Inc.     

The Use of Referential Context and Grammatical Gender in Parsing: A Reply to Brysbaert and Mitchell (2000)

Based on the results of an event-related brain potentials (ERP) experiment (van Berkum, Brown, & Hagoort. 1999a, b), we have recently argued that discourse-level referential context can be taken into account extremely rapidly by the parser. Moreover, our ERP results indicated that local grammatical gender information, although available within a few hundred milliseconds from word onset, is not always used quickly enough to prevent the parser from considering a discourse-supported, but agreement-violating, syntactic analysis. In a comment on our work, Brysbaert and Mitchell (2000) have raised concerns about the methodology of our ERP experiment and have challenged our interpretation of the results. In this reply, we argue that these concerns are unwarranted and, that, in contrast to our own interpretation, the alternative explanations provided by Brysbaert and Mitchell do not account for the full pattern of ERP results.     

汉语双音节同音词词汇歧义消解过程的研究

使用跨通道词汇判断任务和语义启动技术,两个实验分别考察了孤立状态下和句子语境中汉语双音节同音词意义通达的情况,结果发现(1)在孤立状态下,无论ISI为0毫秒还是-150毫秒,与同音词主要或次要意义有关的探测词都受到了促进;(2)当ISI为0毫秒时,在语境一致的条件下,与同音词主要或次要意义有关的探测词均受到了促进,在语境不一致的条件下,则未发现任何促进效应;(3)当ISI为-150毫秒时,只是在语境一致并且探测词与同音词的主要意义有关的条件下才观察到促进效应。     

Searching for Family Therapy in the Rockies: Family Therapists Meet A Paleontologist

Family therapists use concepts germane to other academic disciplines. We recount four notions--context, explanatory metaphors, language conventions, and persistently refining knowledge--that family therapists and paleontologists each utilize. Revisiting family therapy's foundational concepts through the lens of another discipline reminds us of our theoretical beginnings, highlights those professional adaptations that we have made over the years, and offers us an opportunity to reinvigorate and expand our central organizing principles.     

词汇选择中句子语境效应的研究

通过两个词汇选择实验,采用快速选择法对汉语句子语境作用作了考察.结果发现句子语境位置及语境与目标词之间的语法关系对于词汇选择起着重要的作用.这些结果表明(1)前语境为被试对随后出现的目标词有一种预期效应,它对词汇选择的促进作用大于延迟语境;(2)当句子或短语不符合句法时,语境的效应很弱,语境效应的产生依赖于句法、语义等高层次的表征.
