Parental Corporal Punishment and Girls’ Self-Esteem: The Moderating Effects of Girls’ Agency and Communion in China

The current study aimed to examine the moderating effects of girls’ agency and communion in the links between both fathers’ and mothers’ corporal punishment and girls’ self-esteem in China. Chinese girls (n?=?302) enrolled in grades 4–8 were instructed to independently complete the Parent-Child Conflict Tactics Scale (CTSPC), the Children’s Sex Role Inventory (CSRI), the Global Self-Worth subscale of Self-Perception Profile for Children (SPPC), and demographic items. Results indicated that both fathers’ and mothers’ corporal punishment were not directly associated with girls’ self-esteem, whereas both agency and communion were positively associated with girls’ self-esteem. In addition, both fathers’ and mothers’ corporal punishment were significantly and negatively associated with self-esteem for girls with lower levels of agency but not for the girls with higher levels of agency. The current results extend the growing evidence against using corporal punishment as a child-rearing practice and highlight that intervention programs need to focus on eliminating, or at least decreasing, both mothers’ and fathers’ corporal punishment. Additionally, parents and educators need to move from the traditional gender-related attributes to encourage the development of both agency and communion in girls.

     

Stressors and Stressor Appraisals: the Moderating Effect of Task Efficacy

Employees’ cognitive appraisals play important roles in determining how they perceive and react to challenge and hindrance stressors. This study examined the stress process by studying employees’ cognitive appraisals using time-lagged data collected with a time interval of 4 months. There were three major findings. First, challenge appraisals mediated the relationship of job complexity with work motivation and task persistence. Hindrance appraisals mediated the relationship of role conflict with work motivation and task persistence. Second, task efficacy significantly moderated the relationship between job complexity and challenge appraisal, as well as the relationship between role conflict and hindrance appraisal. Employees high in task efficacy were more likely to report challenge appraisals of job complexity than employees low in task efficacy. Employees low in task efficacy were more likely to report hindrance appraisals of role conflict than employees high in task efficacy. Finally, data supported the moderated mediation model in which task efficacy moderated the indirect effect of job complexity on motivation via challenge appraisal. Our study provided important input to the development of stress management interventions.     

Reconsidering the roles of gratitude and indebtedness in social exchange

Receiving favors is often a mixed blessing and commonly triggers two emotions: the positive emotion gratitude and negative emotion indebtedness. In three studies, we examined the hypothesis that gratitude and indebtedness have distinct functions in social exchange. Contrary to current views, we believe that the function of gratitude does not primarily reside in facilitating social exchange. Instead, we propose that indebtedness motivates people to repay favours received, and thus accounts for most of the prosocial effects commonly attributed to gratitude. On the other hand consistent with current views, we believe that gratitude signals the potential for developing a relationship and fosters proximity seeking. Supporting these assumptions, in Study 1 we found that gratitude and indebtedness were associated with aspects of the favour that reflect the concern for relationship and the level of inequity. Studies 2 and 3 provided causal support for these relations, and revealed the unique associations between gratitude and the motivation of proximity seeking, and between indebtedness and the motivation to reciprocate. We argue that this functional distinction has escaped research attention as gratitude and indebtedness are naturally correlated because they stem from the same eliciting event. To appreciate this functional distinction, both emotions should be studied simultaneously in the context of social exchange.     

元认知的神经机制:元认知功能、脑区与脑网络

元认知是指个体对当前进行的认知活动的监测和调节。通过对元认知神经机制研究的梳理,归纳出两条研究主线:一条主线以具体元认知加工的脑区激活研究为主,主要考察元认知与认知过程的分离及典型元认知加工的共享性和特异性。研究发现元认知加工主要与前额叶有关,还涉及脑岛、顶叶、颞叶和楔前叶等部分脑区。另一条主线探讨广泛的元认知功能与广泛大脑网络的相关。研究提出了大脑的“元认知网络”的概念,发现脑损伤或病变造成的元认知功能损伤与脑功能网络有关,而非固定在某一特定脑区。建议未来的研究应重视四个方面的研究:元认知加工的具体脑区和脑功能网络,元认知神经机制的分离,元认知脑功能的损伤和元认知训练的改善作用,以及基于神经机制研究的元认知模型的建构与修正。     

气流冲击法配合吸痰术用于机械通气患者的效果观察

观察气流冲击法配合吸痰术对于行机械通气(MV)患者吸痰的效果及呼吸机相关性肺炎(VAP)的发生率.将59例行人工气道机械通气的患者随机分成两组,对照组采用常规的开放式口鼻咽部吸痰,实验组在常规吸痰的基础上采用简易呼吸器气流冲击法.比较两组患者的痰鸣音、日吸痰次数,连续两次吸痰时间间隔、机械通气时间、VAP发生率、住ICU时间.两组患者MV时间,差异有统计学意义(P=0.00).两组患者痰鸣音改善情况及连续两次吸痰时间差异有统计学意义(P＜0.05).气流冲击法配合吸痰术可以有效清理患者气道分泌物,缩短患者的MV时间,减少肺部并发症.     

False memory and importance: Can we prioritize encoding without consequence?

Given the large amount of information that we encounter, we often must prioritize what information we attempt to remember. Although critical for everyday functioning, relatively little research has focused on how people prioritize the encoding of information. Recent research has shown that people can and do selectively remember information assigned with higher, relative to lower, importance. However, the mechanisms underlying this prioritization process and the consequences of these processes are still not well understood. In the present study, we sought to better understand these prioritization processes and whether implementing these processes comes at the cost of memory accuracy, by increasing false memories. We used a modified form of the Deese/Roediger–McDermott (DRM) paradigm, in which participants studied DRM lists, with each list paired with low, medium, or high point values. In Experiment 1, encoding higher values led to more false memories than did encoding lower values, possibly because prioritizing information enhanced relational processing among high-value words. In Experiment 2, disrupting relational processing selectively reduced false memories for high-value words. Finally, in Experiment 3, facilitating relational processing selectively increased false memories for low-value words. These findings suggest that while prioritizing information can enhance true memory, this process concomitantly increases false memories. Furthermore, the mechanism underlying these prioritization processes depends on the ability to successfully engage in relational processing. Thus, how we prioritize the encoding of incoming information can come at a cost in terms of accurate memory.     

抑郁遗传基础的性别差异

人类抑郁有着复杂的遗传基础并存在性别差异。抑郁遗传基础的性别差异主要表现在遗传的直接效应及遗传与环境的交互效应两个方面。本文在回顾、梳理既有抑郁遗传基础性别差异相关研究的基础上,进一步探讨了性激素、个体环境敏感性和中间表型在性别差异形成中的作用。未来该领域应关注遗传对抑郁的动态影响,进一步探讨多基因交互作用、不同类型与性质的环境指标与抑郁遗传基础性别差异的关联。     

词汇获得年龄在物体和动作图画命名中的不同作用

本研究目的是考察词汇获得年龄(早与晚)这一因素对物体图画和动作图画命名是否产生了不同的影响。采用物体图画和动作图画命名任务,发现:(1)相比于物体图画命名,动作图画命名的反应时更长,表明动词的产生更为复杂。(2)在物体图画命名任务中,与晚获得词相比,早获得的词产生速度更快;相比而言,在动作图画命名中,晚获得词比早获得词的反应时更短,反应速度更快。基于分析和讨论,我们认为Ao A效应可能发生在图画命名过程中的词汇水平,而非概念水平或反应输出阶段。
