数量适应后效的皮层映射特征

本研究探讨了观察者与观察目标存在相对运动时视觉系统对目标数量特征的适应后效的皮层映射特征, 并与对比度适应后效的映射规律进行比较。包括两项实验。其中, 实验一要求被试在适应目标后转换注视点, 考察眼跳后相同和不同视网膜区域以及相同和不同空间区域的适应后效, 发现数量适应后效具有部分空间-皮层映射特性, 而对比度适应后效则表现出完全的视网膜-皮层映射特征。实验二采用固定的注视点, 考察目标运动后目标原位置和新位置区域的适应后效, 发现数量适应后效不完全依赖于视网膜-皮层映射, 它可以“追随”客体运动重新映射到新的位置, 表现出基于客体映射的特征, 而对比度适应后效则完全依赖于视网膜-皮层映射, 不能“追随”客体移动在目标新位置重新形成映射。两项实验结果提示, 相对于对比度等低级表面特征而言, 数量特征对目标的描述涉及更高的加工水平, 它可以与观察目标的相对运动信息进行整合, 且这种整合在眼跳和非眼跳的观察条件下都可发生。     

医调委:功能冲突与制度调适

为了回应日益严峻的医患冲突, 医患纠纷人民调解委员会 (简称\"医调委\") 这一专业性调解组织在全国范围内被广泛地组建起来。研究表明医调委既要维护医疗场所秩序稳定, 又要满足患方权利诉求, 同时还需要保护医疗机构的合法权益, 在很多时候, 这些功能需求存在尖锐的冲突。虽然医调委发展出一些制度性策略来缓和这些功能冲突, 但是效果有限。医调委的长远发展在很大程度上受制于医疗诉讼, 为医调委的长远发展考虑, 需要从理论上进一步思考其组织定位。     

自尊和心理控制源对留守儿童社会适应的影响研究

本研究以积极心理学理论为依据,采用量表法,对农村留守儿童和非留守儿童进行了比较研究。结果表明:留守儿童和非留守儿童在自尊、心理控制源以及社会适应性上都存在着显著性差异。在该研究结果上,深入分析了高自尊和内控归因这两种积极心理品质作为心理弹性的保护性因子对留守儿童社会适应性所发挥的作用。     

Stress,strain, and hardiness as predictors of adaptation in farm and ranch families

We examined the relationship between potential family vulnerability factors (stressor and strains), manifestations of maladaptation (family discord and distress), family strengths (hardiness), and measures of bonadaptation (quality of life) as reported by 188 men and women representing 100 Idaho farm and ranch families. Family strains, and stressors unique to farming and ranching, were positively associated with family discord and distress but negatively associated with hardiness and quality of life. Greater family hardiness as reported by both wives and husbands was positively correlated with their perceptions of family quality of life. The results have implications for mental health professionals and family life educators whose goal is to help farm and ranch families manage stress more effectively, increase hardiness, and enhance their overall quality of life.     

Empower my decisions: The effects of power gestures on confirmatory information processing

Recent research has shown that social power systematically influences information processing in many ways, and can be induced simply via powerful gestures or postures. The current studies investigated the impact of embodied power on confirmatory information processing after decision making. Based upon previous social power research, we hypothesized that individuals who posed in powerful ways (making a clenched fist or sitting in an open, expansive posture) would systematically prefer decision-consistent over decision-inconsistent information; an effect known as selective exposure, or biased assimilation. Four studies consistently indicated that bodily positioning associated with high levels of power induced greater confirmatory tendencies in the evaluation and search stages of a subsequent, decision-relevant information task (Studies 1–4). This tendency is unlikely to be due to mere physical strain (Study 4), and was mediated by differences in experienced decision certainty (Studies 3 and 4); indicating that the embodiment of high power makes people more confident regarding the validity of their decisions. Consequently, high-power posers systematically prefer information that is consistent with their decision preference.     

Assessing the predictive validity of cultural intelligence over time

The study examines four core components of cultural intelligence (CQ) - Behavioral, Motivational, Cognitive and Meta-cognitive - as predictors of cross-cultural adaptation problems in a longitudinal study of international students in New Zealand and tests the hypothesis that Motivational CQ predicts better psychological and sociocultural outcomes over time. One hundred and four students completed measures of CQ during a pre-term orientation program and assessments of adaptation problems approximately three months later. In line with the hypothesis, bi-variate correlations indicated that Motivational CQ was related to fewer psychological symptoms (r = −.30, p < .01) and sociocultural adaptation problems (r = −.27, p < .01). However, hierarchical regression analysis, controlling for age, gender, length of residence abroad and region of origin, revealed that while Motivational CQ was a significant (negative) predictor (ß = −.36, p < .01) of psychological symptoms, the overall amount of variance explained (14.6%) in the model was not significant. In contrast, region of origin (ß = .37, p < .01) was the only significant predictor of sociocultural adaptation problems with international students from Western countries reporting fewer difficulties than those from other regions. The results are discussed in relation to contemporary theories of motivation along with recommendations for future research.
