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。 相似文献

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。 相似文献

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. 相似文献

Automated vehicles (AVs) are expected to improve traffic flow efficiency and safety. The deployment of AVs on motorways is expected to be the first step in their implementation. One of the main concerns is how human drivers will interact with AVs. Dedicating specific lanes to AVs have been suggested as a possible solution. However, there is still a lack of evidence-based research on the consequence of dedicated lanes for AVs on human drivers’ behavior. To bridge this research gap, a driving simulator experiment was conducted to investigate the behavior of human drivers exposed to different road design configurations of dedicated lanes on motorways. The experiment sample consisted of 34 (13 female) licensed drivers in the age range of 20–30. A repeated measures ANOVA was applied, which revealed that the type of separation between the dedicated lane and the other lanes has a significant influence on the behavior of human drivers driving in the proximity of AV platoons. Human drivers maintained a significantly lower time headway (THW) when driving in the proximity of a continuous access dedicated lane as compared to a limited-access dedicated lane with a guardrail separation for AV platoons. A similar result was found for the limited-access dedicated lane in comparison to the limited-access dedicated lane with guardrail separation. Moreover, the results regarding the empirical relationships between THW and sociodemographic variables indicate a significant THW difference between males and females as well as a significant inverse relationship between THW and the years of driving experience. 相似文献

There seems to be a widespread view that foreign lorry drivers’ lack of competence on Norwegian roads, especially related to winter driving, is a significant safety problem. It has, however, been suggested that foreign heavy goods vehicle (HGV) drivers perform better than expected on Norwegian winter roads, as they feel less safe than Norwegian drivers, and adapt by driving slower and more carefully. The aim of the present paper is twofold. First, we examine whether foreign HGV drivers in Norway actually have poorer competence on, training for, experience with and equipment for winter driving than Norwegian HGV drivers. Second, we discuss whether the expected negative effect of these safety challenges is mitigated, as foreign HGV drivers adapt their behaviours. We use four data sources to shed light on the aims: (1) interviews, (2) roadside inspections, (3) small-scale survey and (4) towing incidents. Our data support the hypothesis about behavioural adaptation, indicating that foreign HGV drivers experience winter driving as more difficult or unsafe, as they have supposedly less suitable vehicles and equipment, less experience, training and competence for winter driving. They are therefore more likely to get stuck while driving uphill on winter roads, supposedly as they drive more carefully and slower than Norwegian HGV drivers. Norwegian HGV drivers feel safer and more confident while driving on winter roads, because of their equipment and their experience. 相似文献

ObjectiveWithin the football and futsal refereeing context, even though referees work within teams, there is very little research considering the implications of team dynamics. In response, this study starts to address this gap in the literature by investigating the moderating effect of mental models on the relationship between self-efficacy beliefs and perceptions of team adaptation within the exciting context of professional and national football and futsal refereeing.DesignWe obtained online questionnaires from 339 active football and futsal referees within the National and Professional league at two distinct points (April and May) within the football season.ResultsSelf-efficacy beliefs were positively associated with perceptions of team adaptation (only for football referees). Mental models were positively associated with team adaptation. Likewise, the moderation between mental models and self-efficacy beliefs was positively associated with perceptions of team adaptation. However, such an effect was only significant at the futsal referees’ level.ConclusionThis study emphasises the importance of mental models for team adaptation and the importance of self-efficacy beliefs in predicting perceptions of team adaptation. We hope that this study represents the first step in a greater appreciation of the salience of team dynamics and their impact on football and futsal referees’ performance and that future research can build upon our work. 相似文献

This study used a narrative approach to examine the difficulties that older visually impaired people experience when adapting to life in a nursing home. The interview data were collected from one blind aged person (n = 1), focusing on the adaptation process from moving into the nursing home to the present and maintaining context of narrative that included the life history. Subcategories were extracted based on a framework of temporal coherence, causal coherence, thematic coherence, and situational coherence. This study revealed three factors related to adaptation to life in a nursing home for a visually impaired person, including psychological adaptation: becoming accustomed to life in the facility after changes in the living environment, having gratitude and maintaining “moderating human relationships,” and participating in activities connected to one's purpose in life. He was able to psychologically adapt and came to accept his death through an awareness of aging. 相似文献

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. 相似文献

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. 相似文献
