雇主品牌结构与求职倾向关系

利用重新修订非特指行业的雇主品牌量表,以求职倾向为因变量,通过两个有递进关系的研究,证实不仅雇主品牌结构的功能特征正向影响求职倾向,雇主品牌结构的象征特征与求职者追求的理想自我形象一致性也正向影响求职倾向,表明人们求职时既注重满足个人物质利益的雇主品牌功能特征,也关注求职企业雇主的特征风格与自我理想形象的契合。     

空间参照框架的产生机制及与认知机能的关系

空间参照框架是个体表征空间方位的方式, 按照表征中心的不同分为自我中心和环境中心两种参照框架。长期对某一参照框架的持续激活可以形成对该空间参照框架的偏好, 不仅会影响个体的神经元结构, 还会对认知机能产生重要影响。偏好环境中心参照框架会增加海马及其附近脑区的灰质, 而偏好自我中心参照框架会增加尾状核的灰质。海马灰质体积增大会增强正常人的空间记忆能力。持续激活环境中心参照框架的个体会增加海马灰质体积, 从而降低患老年痴呆的风险。未来研究应关注, 地域差异、城乡差异等环境差异在空间参照框架与认知机能关系中的影响机制, 并进一步收集空间参照框架训练在老年痴呆病人中干预效果的实证证据。     

面孔审美加工的神经机制及个体差异

外显和内隐的面孔审美加工的脑成像研究表明,美的面孔比不美的面孔导致眶额皮层、伏隔核、杏仁核等奖赏脑区更大的激活。脑电研究则发现了与面孔审美加工有关的早期负波和晚期正成分。面孔审美加工有关的脑区活动也受到性别、生理周期等个体因素的调节。未来的研究需要比较美的面孔与其它奖赏刺激加工的神经机制,探讨面孔审美加工的不同阶段及时间进程,在面孔知觉的框架下形成合理的面孔审美加工的神经模型。

唤醒度对汉语情绪词情绪启动效应的影响

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。     

Type D personality,illness perception,social support and quality of life in continuous ambulatory peritoneal dialysis patients

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.     

肥胖成因的解释——基于食物奖赏研究的视角

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。     

Frames of reference in mobile augmented reality displays

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.     

A compromise between self-enhancement and honesty: Chinese self-evaluations on social desirability scales

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.
