Message sidedness in advertising: the moderating roles of need for cognition and time pressure in persuasion

Persuasion has been extensively researched for decades. Much of this research has focused on different message tactics and their effects on persuasion (e.g., Chang & Chou, 2008; Lafferty, 1999). This research aims to assess whether the persuasion of a specific type of message is influenced by need for cognition (NFC) and time pressure. The 336 undergraduates participated in a 2 (message sidedness: one-sided/two-sided) × 3 (time pressure: low/moderate/high) between-subjects design. Results indicate that two-sided messages tend to elicit more favorable ad attitudes than one-sided messages. As compared with low-NFC individuals, high-NFC individuals are likely to express more favorable ad attitudes, brand attitudes and purchase intention. Moderate time pressure tends to lead to more favorable ad attitudes than low time pressure and high time pressure. In addition, moderate time pressure is likely to elicit more favorable brand attitudes and purchase intentions than high time pressure, but does not elicit more favorable brand attitudes and purchase intentions than low time pressure. Furthermore, when high-NFC individuals are under low or moderate time pressure, two-sided messages are more persuasive than one-sided messages; however, message sidedness does not differentially affect the persuasion when high-NFC individuals are pressed for time. In contrast, one-sided messages are more persuasive than two-sided messages when low-NFC individuals are under low or high time pressure, and two-sided messages are more persuasive than one-sided messages when low-NFC individuals are under moderate time pressure.     

Decision-specific reinvestment scale: An exploration of its construct validity,and association with stress and coping appraisals

ObjectiveThis research project aimed to explore the construct validity of the Decision-Specific Reinvestment Scale (DSRS); more specifically, its links with stress and coping appraisals.DesignStudy 1 validated the DSRS and the Movement-Specific Reinvestment Scale (MSRS) to the French language, in order to examine the construct validity of the DSRS using the MSRS, the Preference for Intuition and Deliberation (PID) inventory and the Melbourne Decision-Making Questionnaire (MDMQ). In addition, sex differences in reinvestment were investigated. Study 2 examined stress and coping appraisals of high and low reinvesters.MethodIn study 1, 379 athletes completed the DSRS, MSRS, PID, and MDMQ. In study 2, 100 handball players, classified as low and high reinvesters, completed surveys aimed to assess stressor intensity, stressor perceived controllability, coping effectiveness, subjective performance and coping strategies with the Coping Inventory for Competitive Sport over three games.ResultsIn study 1, we found that intuitive athletes scored lower on the DSRS in comparison to deliberative athletes, whilst no difference was found for the MSRS. Convergent and discriminant validity was illustrated with the subscales of the MDMQ. No sex differences were found regarding reinvestment. In study 2, findings showed that low reinvesters scored higher than high reinvesters in terms of stressor perceived controllability, coping effectiveness and subjective performance.DiscussionIn addition to confirmation of construct validity, these findings strengthen our understanding of how high decision reinvesters perceive a pressured situation. Key applications are derived from our findings informing coaches and athletes in offsetting the negative effects of reinvestment on sport performance.     

Perceived parental pressure and perceived coach pressure in adolescent and adult sport

ObjectiveThe purpose of this study was to investigate whether adolescent and adult athletes’ perceptions of interpersonal perfectionistic performance pressures from parents and coaches differ as a function of athlete age.DesignA cross-sectional repeated-measures design was employed.MethodA total of 1544 youth sport athletes (M age = 15.44 years; SD = 2.12) and 1706 adult sport athletes (M age = 20.80 years; SD = 2.09) provided self-report levels of perceived parental pressure (PPP) and perceived coach pressure (PCP) in sport.ResultsStatistically significant interaction effects (ps < .001) were obtained from two repeated-measures analyses of variance. Interaction effects indicated that PPP tended to be lower in older/adult sport athletes than younger/adolescent sport athletes, whereas PCP tended to be higher in older/adult sport athletes than younger/adolescent sport athletes. Significant main effects (ps < .001) also revealed that, regardless of age and whether athletes competed in youth sport or adult sport, athletes had a tendency to perceive more pressure from coaches than parents.ConclusionResults highlight the need to differentiate between parents and coaches as potential sources of interpersonal perfectionistic pressures in sport. Results also demonstrate that athletes’ perceptions of parent and coach pressure surrounding performance expectations and standards in sport can differ as a function of athlete age. Future research that examines perfectionism in sport from a developmental perspective is recommended.     

I've Got My Eyes on You: Implicit Social‐Pressure Cues and Prosocial Behavior

Explicit social pressure has been shown to be a powerful motivator of prosocial behavior‐like voting in elections. In this study, I report the findings of a randomized field experiment designed to study the impact of more subtle, implicit social‐pressure treatments. The results of the experiment, conducted in the October 2011 municipal elections in Key West, Florida, demonstrate that even subtle, implicit observability cues can effectively mobilize citizens to vote, perhaps as much as explicit surveillance cues. The findings speak more broadly to our understanding of human decision making, and even evolution, and provide fodder for the claim that humans are evolutionarily programmed to respond to certain stimuli. I interpret the evidence to support the notion that evolutionarily charged impulses, like exposure to images that implicitly signal the potential for surveillance and observability, are sufficient to overcome powerful collective action incentives to free ride.     

正常高值血压者血压昼夜节律与靶器官损害的相关性研究

探讨正常高值血压昼夜节律与靶器官损害的相关性。入选正常高值血压者150例,其中杓型组72例,非杓型组78例,60例正常血压者为对照组。检测尿白蛋白排泄率（UAE）、颈动脉内膜中层厚度（IMT）和左心室重量指数（LVMI）。杓型组和非杓型组UAE、IMT、LVMI高于对照组（P＜0．01）。非杓型组UAE、IMT、LVMI高于杓型组（P＜0．05）。正常高值血压人群已出现靶器官损害,血压昼夜节律异常与早期靶器官损害密切相关。     

脉理的阴阳和谐观研究--以《濒湖脉学》“缓脉”为中心论证

在《濒湖脉学》的脉理中,把无病的缓脉认为是有神、有胃气的平脉,无病的缓脉是脾胃这一人体后天之本正常运化的脉象。脾脉为缓脉,其余四脏脉以及四季脉也要兼有缓脉,才是阴阳和谐的脉象,脾脉拥有阴阳和谐的缓脉能为其余各脏腑提供精气,从而保证各脏腑的正常运化,只有各脏腑的正常运化才能维护人身体的阴阳和谐。当人身体的阴阳失去和谐出现病变的时候,脉象就会表现为太过或不及或各脏脉俱缓,少有或失去了缓和的脉象以及各脏脉均失去个性的病缓脉。     

骨延长的骨愈合原理

骨延长愈合与骨折愈合等多种多样的骨修复现象可能具有相同的细胞生物学基础,这个理论称为骨修复一元论.血管内皮细胞是启动骨修复的感受器,破骨细胞通过分泌骨形态发生蛋白（BMP）启动骨特异性修复.骨折间隙间断性的力学脉冲通过血管内皮细胞不断地转化为骨修复的生物学脉冲.在微损伤条件下,骨修复具有放大效应.保护下负重和功能锻炼是下肢骨骼延长术后的重要原则.     

根据血压昼夜节律选择服药时间控制血压晨峰

根据血压昼夜节律,观察给药时间对血压晨峰的影响。256例原发性高血压患者,经24h动态血压监测分为超杓型（n＝49）、杓型（n＝127）和非杓型（n＝80）3组;各组再分为清晨服药组和晚上服药组。用药6周,比较用药前后血压昼夜节律及血压晨峰的变化,发现在改变血压昼夜节律及降低血压晨峰方面,超杓型组清晨服药优于晚上服药,非杓型组晚上服药优于清晨服药;杓型组清晨服药与晚上服药均能降低晨峰值,提示根据个体血压昼夜节律选择服药时间能更好地控制血压晨峰。
