肥胖致心肌脂毒性的机制的研究进展

肥胖是体内脂质过度沉积的一种状态,其不仅可引起糖脂代谢紊乱、胰岛素抵抗,从而继发糖尿病、高血压、冠心病等疾病,而且当脂质水平超过脂肪细胞的储存容量及出现胰岛素抵抗时,血液中游离脂肪酸含量会随之升高,进而可引起脂质在心脏的异位沉积.沉积于心肌细胞的脂质可进一步通过神经酰胺、内质网应激等机制影响心肌细胞的结构和功能,最终导致心力衰竭的发生.但肥胖所致心肌脂毒性具体机制不明,本文就肥胖所致心肌脂毒性可能机制做一综述.     

宗教研究的认知科学新取向

宗教认知科学是新近出现的从认知和进化的角度研究宗教的分支学科。主要有认知副产物和社会适应两种理论。认知副产物理论认为宗教信仰是人类认知倾向的副产物;社会适应理论认为宗教信仰促进群体的团结合作,是一个精巧的社会适应机制,有助于群体的自然选择。两种理论引发了系列的实验研究,由于宗教认知科学仍处于理论研究向实证研究的过渡阶段,未来需统一概念,加强实验范式的建立,更多地借助认知科学的方法和工具开展实证研究。     

The State,Not the Trait,of Nostalgia Increases Creativity

Nostalgic experience evokes emotions and activates the cognitive process of recalling and reconstructing information in memory. This study investigated the effects of nostalgia on creativity using experiments and questionnaires. Two-hundred-and-eighty university students were randomly assigned to experimental and control groups, in which participants received and completed different writing tasks (nostalgic experience vs. common life experience). They also responded to questionnaires measuring personality, nostalgia proneness, and creativity. Results showed that participants who were primed with nostalgic experience demonstrated higher creativity than the control group. In both groups, women demonstrated higher creativity than men. When specific aspects of the nostalgic experience were used to predict creativity, results showed that: (a) nostalgia triggered by social interaction and negative affect was positively related to creativity; (b) nostalgic experience containing tangibles positively predicted creativity; (c) the total number of triggers and the amount of, but not the positivity or salience of self in, nostalgia narrative contributed positively to creativity; and (d) higher agreeableness and openness, but not nostalgia proneness or other personality traits, were associated with higher creativity. Implications for both research and practice are discussed.     

Dialectical thinking and health behaviors: The effects of theory of planned behavior

The primary purpose of this study was to investigate whether the theory of planned behavior (TPB) mediated the relationship between dialectical thinking and health behaviors. A sample of 285 undergraduates was tested with a dialectical thinking styles scale, health promoting lifestyle profiles, and TPB questionnaires. Structural equation modeling was used for data analysis. Results indicated that all the three dimensions of thinking styles (belief in the connection, acceptance of change, and acceptance of contradiction) exerted significant effects on TPB constructs. Specifically, the connection and the change dimensions had positive effects on health behaviors mediated by TPB, whereas the contradiction dimension had a negative effect. Model 2 showed a satisfactory fit, demonstrating the influential pathways between dialectical thinking and health behaviors. Implications in issues of health promotion and future research are discussed.     

Differentiation of stages in joke comprehension: Evidence from an ERP study

This study aimed to investigate the mechanisms underlying joke comprehension using event‐related potentials (ERPs). Fourteen healthy college students were presented with the context of a story without its joke or nonjoke ending, and then, when the story ending was presented, they were asked to make a funny/unfunny judgment about these endings. The behavioral results showed that there was no significant difference between funny and unfunny items, which meant that subjects could understand funny items as easily as unfunny ones. However, the ERP results showed that funny items initially elicited a more negative ERP deflection (N350–450) over frontocentral scalp regions. Dipole analysis localized the generators in the left temporal gyrus and the left medial frontal gyrus; it is suggested that these areas might be involved in detecting the incongruent element in joke comprehension. Between 600 and 800 ms, funny items subsequently elicited a more negative ERP deflection (N600–800) over frontocentral scalp regions and a more positive ERP deflection (P600–800) over posterior scalp regions. Dipole analysis localized the generator in the anterior cingulate cortex (ACC), an area involved in the breaking of mental set/expectation and the forming of novel associations. Finally, funny items elicited a more positive ERP deflection (P1250–1400) over anterior and posterior scalp regions. Dipole analysis localized the generators in the middle frontal gyrus and the fusiform gyrus, areas that might be related to the affective appreciation stage in joke process. Unlike that of Coulson and Kutas (2001), the present study might support the hypothesis of a three stage model of humor processing (humor detection, resolution of incongruity and humor appreciation).     

The Effect of Companion's Gender on Impulsive Purchasing: The Moderating Factor of Cohesiveness and Susceptibility to Interpersonal Influence

Most impulse purchasing research investigates individual‐level factors. This paper, however, examines the influence of shopping companion gender on impulse purchasing. The results of the three studies show that shoppers were more likely to exhibit impulse purchase behavior when shopping with an opposite gender companion. In addition, shoppers who were in the low‐cohesive condition and who shopped with an opposite gender companion were more likely to exhibit impulse purchase behavior than those who shopped with the same gender companion, and those who were susceptible to interpersonal influence were also more likely to exhibit impulse purchase behavior when shopping with an opposite gender companion. For shoppers who were not as susceptible to interpersonal influence, the influence of their companion's gender appeared to diminish on impulsive purchasing.     

Perceptions of Age and Creativity in the Workforce

As the workforce ages it becomes important to examine if there is misperception of creativity and age in work contexts. A laboratory experiment examined perceptions of the creativity of a team with both young and old workers and of a team composed entirely of young workers. Scripted videos portrayed such teams engaged in designing an outdoor advertising campaign. Altogether, 220 participants were randomly assigned to watch one of the video clips and complete a structured questionnaire. No significant differences were observed in the perceptions of the two teams' performance or of the quality of the resulting advertising proposal. In general, there was also no significant difference in the individual characteristics attributed to the four characters on the teams. However, participants aged 35 or above evaluated both teams and all four characters more favorably than participants aged 20–34.     

Cultural influences on terror management: Independent and interdependent self-esteem as anxiety buffers

Terror management theory (TMT) proposes that self-esteem serves as a defense against the fear of death. Previous research has suggested that independent self-esteem is more salient in individualist cultures, whereas interdependent self-esteem is more salient in collectivist cultures. Thus, we hypothesized that in collectivist cultures, independent self-esteem would play a lesser role and interdependent self-esteem a greater role in terror management, compared to individualist cultures. The results support this prediction. In Study 1, personal self-esteem was negatively associated with death anxiety in samples from a Western (Austria) and Eastern (China) culture. However, both self-liking and self-competence were negatively associated with death anxiety among Austrian participants, but only self-liking (and not self-competence) was so among Chinese participants. Surprisingly, collective self-esteem was not significantly correlated with death anxiety. Yet, Study 2 showed that among Chinese participants, relational self-esteem was negatively associated with death anxiety. Study 3 examined the roles of relational versus personal self-esteem in moderating the effects of mortality salience on worldview defense. Among Chinese participants, relational rather than personal self-esteem increased the defense of worldviews centered on collectivist-Chinese values following mortality salience (Study 3a). In contrast, among Austrian participants, personal rather than relational self-esteem attenuated the effect of mortality salience on the defense of individualist-Austrian worldviews (Study 3b). Self-esteem serves a terror management function in both collectivist and individualist cultures; however, the differences between cultural worldviews determine the type of self-esteem that is more relevant to terror management processes.
