使用词汇情绪启动的实验范式,通过两个行为实验探讨了不同SOA(100ms、300ms和500ms)条件下情绪唤醒度在情绪启动效应中的作用,以及情绪启动效应是否受到任务形式的影响。结果发现,在情绪效价判断任务中,SOA为100ms时高唤醒和低唤醒启动词都出现了情绪启动效应,SOA为300ms时只有高唤醒启动词出现了情绪启动效应。在真假词判断任务中,无论高唤醒还是低唤醒启动词都没有出现情绪启动效应。唤醒度是影响词汇情绪启动效应的重要因素,但这种效应不是完全自动化的过程,会受到SOA和任务导向的影响。情绪启动效应可能来自于启动词与目标词在反应趋向上的一致性趋势。 相似文献

The previous studies reported Type D was associated with poor quality of life (QoL), increased psychological distress, and impaired health status in cardiac patients. The aim of this study is to assess the relationships among Type D personality, illness perception, social support, and investigate the impact of Type D personality on QoL in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14). Illness perceptions were assessed using the Chinese version of the Brief Illness Perception Questionnaire (B-IPQ). Social support status was assessed by the well-validated social support rating scale (SSRS). Patients’ QoL was assessed by using Medical Outcomes Short Form 36 (SF-36), respectively. The Type Ds had significantly lower objective support score (8.18 ± 2.56 vs. 9.67 ± 3.28, p = 0.0001), subjective support score (6.71 ± 2.0 vs. 7.62 ± 1.93, p = 0.0001) and utilization of social support score (6.76 ± 2.0 vs. 7.61 ± 1.94, p = 0.0001) than that of the non-type Ds. Type Ds believed their illness had much more serious consequences (7.67 ± 2.64 vs. 6.27 ± 3.45, p < 0.001), and experience much more symptoms that they attributed to their illness (6.65 ± 2.54 vs. 7.31 ± 2.36, p = 0.023). Significant differences were found between Type Ds and non-Type Ds in PCS (40.53 ± 6.42 vs. 48.54 ± 6.21 p < 0.001) and MCS (41.7 1 ± 10.20 vs. 46.35 ± 9.31, p = 0.012). The correlation analysis demonstrated that Type D was negatively associated with physical component score (PCS) (r = –0.29, p < 0.01), mental component score (MCS) (r = –0.31, p < 0.01), and social support (r = –0.24, p < 0.001). Using multiple linear regression analysis, we found that Type D personality was independently associated with PCS (β = –0.32, p < 0.001) and MCS (β = –0.24, p < 0.001). Type D personality was a predictor of poor QoL in CAPD patients. The current study is the first to identify a strong association among Type D, illness perceptions, social support and QoL in CAPD patients. The worse illness perceptions and lower social support level therefore represent possible mechanisms to explain the link between Type D and poor QoL in CAPD patients. 相似文献

肥胖的形成和发展受生物、心理和社会因素的共同作用,其中食物奖赏对肥胖的产生有重要的作用。食物是一种自然奖赏,它指机体天生对食物的渴望和依赖。食物奖赏包括"wanting"、"liking"以及"learningreinforcement"三个成分,每个成分由相应的神经通路表征。食物奖赏调控机体的摄食行为并以此调控体重变化。目前,关于肥胖与食物奖赏关系的理论模型主要有刺激—敏感化理论、奖赏过度理论以及奖赏不足理论。采用横断面设计、前瞻研究设计和纵向被试内重复测量设计,使用食物图片线索和直接给予美味奶昔的技术方法,人类脑成像研究从不同侧面为以上三个理论模型提供了证据。除此之外,食物奖赏还受基因的调控。目前,研究者关注较多的是多巴胺D2受体基因Taq IA rs1800497的多态性和FTO基因rs9939609的多态性对食物奖赏及体重改变的调控。 相似文献

Frames of reference in mobile augmented reality displays 总被引:1,自引:0,他引:1

In 3 experiments, the authors investigated spatial updating in augmented reality environments. Participants learned locations of virtual objects on the physical floor. They were turned to appropriate facing directions while blindfolded before making pointing judgments (e.g., "Imagine you are facing X. Point to Y"). Experiments manipulated the angular difference between the learning heading and the imagined heading and between the actual heading and the imagined heading. The effect of actual-imagined on pointing latency was observed for naive users but not for users with brief training or instructions concerning the fact that objects can move with body movements. The results indicated that naive users used an environment-stabilized reference frame to access information arrays, but with experience and instruction the nature of the representation changed from an environment stabilized to a body stabilized reference frame. 相似文献

In this investigation, 202 Chinese college students were asked to complete the 48-item revised Marlowe-Crowne Social Desirability Scale (Crowne & Marlowe, 1960) which contains 32 items from the original version for the purpose of rating item desirability and estimating the percentage of others in general who would behave in the manner described by these items. Analysis indicated (a) nearly all original items keyed in the original direction, which suggests similar fundamental values are prevalent among American and Chinese college students; (b) the distribution of Chinese scores on the 32 items was somewhat positively skewed rather than negatively skewed as in some Western studies of American and Canadian college students. Also, (c) Chinese subjects perceived that they did significantly more desirable and slightly fewer undesirable things than others from which one may infer that Chinese college students tended to give both self-enhancing and honest responses to present good images; however, their need for self-enhancement may take precedence over the need to be honest. (d) Subjects chose to give more honest responses to undesirable items than to desirable ones because the more undesirable items were rated as approximately more neutral than were more desirable ones. Hence, endorsing such undesirable items would not threaten their self-esteem or face. It can be seen that Chinese subjects made an intelligent compromise between self-enhancement and honesty. 相似文献

Are Chinese narcissists disagreeable? Evidence from self‐ and peer‐ratings of agreeableness 下载免费PDF全文
Many studies have found that narcissism is negatively related to agreeableness in Western samples. Four experiments explored this relationship in a Chinese population. In Study 1, 228 junior high school students reported their narcissism and Five Factor Personality traits. In Study 2, participants recruited through the internet completed the measures of narcissism and agreeableness. In Study 3, 145 college students completed the measures of narcissism and agreeableness, as well as self‐esteem and social desirability. In Study 4, 204 senior high school adolescents reported their own narcissistic and agreeableness personality traits. They also received peer‐ratings of agreeableness. We found that narcissism was positively related with self‐reported agreeableness (Study 1, 2 and 4), but not with other ratings of agreeableness (Study 4). Chinese narcissists perceived themselves as agreeable, and their self‐perceptions of agreeableness were more positive than their peers rated them. We discuss the current findings in relation to the Chinese cultural context and underscore cultural roots of narcissism. 相似文献

反事实思维是对过去发生事情进行否定而产生的假设性思维表征,对行为改变和绩效改善有显著影响。因此,作为一种重要的认知策略,反事实思维常常被用于行为干预的研究。本研究采用单因素(反事实启动/经验启动)被试间实验设计,以4种常见的行人不安全行为为实验材料,运用顺序启动范式的语义启动分别激活自变量的两个水平,将遵守交通规则行为意向的评分和反应时双变量作为因变量指标,探索反事实思维对行人安全行为的促进作用。结果表明:与基线水平和经验启动相比,反事实启动诱导产生的行人交通安全行为意向更加积极,并且产生的自动化水平更高。文章最后讨论了研究的理论意义和对安全管理实践的启发。 相似文献
