When is sociality congruent with self-care?

Kumar and Epley (2023) argue that people underinvest in spending time, effort, and money on other people, and that consumers' own well-being would improve from increased “sociality.” We pose two questions to enhance understanding of the relationship between sociality and efforts to benefit one's own well-being: (1) when will other-oriented consumption promote versus hinder consumers' own well-being, and (2) what leads consumers to embrace versus forego efforts to improve their well-being (i.e., self-care) that does not involve sociality? We propose that the degree to which the consumer is concerned about incorporating others' preferences, the magnitude of resources involved, and the temporal dynamics of consumption will be relevant factors in addressing these two questions. Future research to explore the proposed three factors and other factors will be important for consumers who seek to improve their well-being as well as marketers who seek to promote it.     

Representing Sudden Shifts in Intensive Dyadic Interaction Data Using Differential Equation Models with Regime Switching

A growing number of social scientists have turned to differential equations as a tool for capturing the dynamic interdependence among a system of variables. Current tools for fitting differential equation models do not provide a straightforward mechanism for diagnosing evidence for qualitative shifts in dynamics, nor do they provide ways of identifying the timing and possible determinants of such shifts. In this paper, we discuss regime-switching differential equation models, a novel modeling framework for representing abrupt changes in a system of differential equation models. Estimation was performed by combining the Kim filter (Kim and Nelson State-space models with regime switching: classical and Gibbs-sampling approaches with applications, MIT Press, Cambridge, 1999) and a numerical differential equation solver that can handle both ordinary and stochastic differential equations. The proposed approach was motivated by the need to represent discrete shifts in the movement dynamics of \(n= 29\) mother–infant dyads during the Strange Situation Procedure (SSP), a behavioral assessment where the infant is separated from and reunited with the mother twice. We illustrate the utility of a novel regime-switching differential equation model in representing children’s tendency to exhibit shifts between the goal of staying close to their mothers and intermittent interest in moving away from their mothers to explore the room during the SSP. Results from empirical model fitting were supplemented with a Monte Carlo simulation study to evaluate the use of information criterion measures to diagnose sudden shifts in dynamics.     

光栅朝向分辨学习中存在关于45°对角线对称的镜像迁移

采用光栅朝向分辨任务来探讨视知觉学习中是否存在关于45°对角线对称的镜像迁移现象.训练被试分辨15°或75°朝向3或5d,每天约1h,训练前后测量15°、75°、45°朝向的分辨阈值.通过训练,训练朝向(15°或75°)的阈值下降,该学习效应没有迁移至45°朝向,但基本迁移到关于45°对称的朝向(75°或15°)上.这提示,视知觉学习可能发生在中间视皮层,该皮层同时具有一定的朝向特异性和关于45°对角线对称的镜像迁移性.     

物理旋转的有限性对自我旋转的影响

心理旋转与物理旋转是人类所具有的两种动力转换能力,物理操作与心理加工之间的相互关系是空间认知领域关注的热点问题.本研究采用2×4混合实验设计,通过控制旋转轴和旋转角度,对基于不同物理旋转经验的水平面和冠状面自我旋转进行对比性研究.实验结果表明,物理旋转的有限性是影响自我旋转的重要因素,水平面自我旋转易于冠状面自我旋转.     

大学生的社会支持、孤独及自尊对主观幸福感的作用机制研究

对389名大学生施测社会支持量表、自尊量表、社会与感情孤独量表及主观幸福感量表,以探讨孤独和自尊在社会支持与主观幸福感的关系中的作用。结果表明：（1）主观幸福感与社会支持、自尊、孤独呈显著相关。（2）路径分析表明,自尊、孤独分别在社会支持与主观幸福感之间起显著的中介作用。社会支持→自尊→孤独→主观幸福感的显著路径表明,这些变量间存在更为复杂的关系。这些结果对于大学生心理健康教育具有重要的意义。     

认知特征、场独立性与飞行空间定向关系的研究

通过认知分化测验（ＣＬＢ）、团体镶嵌图形测验（ＧＥＦＴ）以及飞行定向水平的模糊评价技术,旨在检验认知特征、场独立性和飞行空间定向水平之间的关系。研究结果表明;（１）高水平的视觉空间认知能力及较强的场独立性特征不仅有助于获得一个良好的飞行定向水平,而且还构成了预测定向水平差异的有效指标;（２）场独立性特征与空间认知特征之间存在着一个很高的相关。具有较强场独立性特征的飞行员往往也具有较为典型的空间认知特征;（３）错觉水平较低的飞行员与中、重度错觉水平组飞行员在空间认知、认知分化和场独立性上的得分分别构成了显著的差异,表明轻度组飞行员在空间定向中表现出了良好的视觉空间信息组织、加工和某些元认知技能方面的优势。研究结果进一步证明了视觉空间认知加工和场独立性水平与飞行空间定向之间的紧密关系。     

风险决策与博彩行为的眼动特点

为了探索博彩行为与风险决策的特点,采用眼动研究方法对博彩行为中的风险决策任务进行了实验,结果发现:(1)外部框架表征虽影响决策者的内部表征,但决策者的内部表征方式表现出稳定的规律;(2)参与者在博彩中面对损失时,认知加工的决策时间比在面对收益的博彩任务的决策时间长,凝视次数也多比较多,决策者的瞳孔直径比面对收益任务下更大;(3)博彩参与者的内部表征方式,随博彩任务的外部表征的框架,金额、概率、备择项间倍数的改变而发生变化.结论:概率信息是博彩任务中的决策者稳定的决策权重;决策者在面对损失时会更加敏感,导致在决策过程中给予更多的加工负荷;博彩任务的外部表征对参与者内部表征有显著影响.     

注意力资源限制与双任务的相互干扰机制

采用心理不应期研究范式, 两个反应时实验检测了注意力资源分配的特征以及双任务的相互干扰机制。每次实验中, 要求被试快速、相继对高低音辨别任务(T1)和Stroop任务(T2)作出选择性反应, T1和T2间采用6种不同的时间间隔(SOA), 以系统考察不同SOA条件下两个任务的反应时走势。结果发现：(1) 在重叠的双任务情境中, T1的中枢加工导致在T2上出现显著的PRP效应, T2的中枢反应选择对T1的反应选择和反应执行加工同样产生显著的影响。SOA以及T2的难度与复杂度实质性地影响了T1的反应选择和反应执行加工。(2) 当两个任务同时需要进行中枢反应选择加工时, 一个任务占用更多的注意资源将导致另一任务获得较少的注意资源, 注意资源量的多寡直接决定了该任务的加工效率。(3) 两个任务的加工相互影响、相互制约, 这种制约机制不仅仅存在于中枢反应选择阶段, 在反应执行阶段仍然存在。     

Specific Virtues as Predictors of Smartphone Addiction among Chinese Undergraduates

Smartphones are important communication and technological tools that have become an indispensable part of university students’ lives. Although empirical research has evaluated factors that influence Smartphone addiction, few studies have explored positive and potentially protective factors such as virtues that may increase the efficacy of future Smartphone addiction prevention programs. Thus, this study examined the relationship between three key virtues (i.e., relationship, vitality, and conscientiousness) and Smartphone addiction as well as evaluated the specific contributions of these virtues as applied to Smartphone use among Chinese university students. A total of 682 undergraduates (aged 18–24 years) from three universities completed the 96-item Chinese Virtues Questionnaire and Mobile Phone Addiction Index. Results showed that three virtues were significantly correlated with Smartphone addiction. Specifically, conscientiousness and relationship virtues negatively predicted Smartphone addiction and explained 82.61% of addiction-related variance. Vitality positively predicted Smartphone addiction and accounted for the remaining 17.39% variance. Thus, this study demonstrated that conscientiousness and relationship virtues were potential protective factors for Smartphone addiction, while vitality led to increased vulnerability. Gender-related differences were also discovered. Specifically, male students may be more sensitive to the conscientiousness virtue, while female students may show increased sensitivity to the relationship virtue. Consequently, future efforts to prevent Smartphone addiction could focus on how to enhance conscientiousness and relationship virtues and how to reduce the vitality virtue.     

Effects of Self-Esteem and Depression on Abnormal Eating Behavior among Korean Female College Students: Mediating Role of Body Dissatisfaction

Body dissatisfaction is widely acknowledged to exert considerable impact on abnormal eating behavior. Previous studies that reported the mediating role of body dissatisfaction between psychological variables and abnormal eating behavior mostly used western samples. The aim of this study was to investigate the direct and indirect association of psychological factors (i.e., self-esteem and depression) on abnormal eating behavior on a Korean sample. In addition, we examined a possible mediating effect of body dissatisfaction in this relationship. A sample of 502 Korean female college students enrolled in a private university participated in this cross-sectional study. Results indicated that self-esteem and depression did not have direct impacts on abnormal eating behavior. However, they did have indirect effects through the mediating factor, body dissatisfaction. Our findings suggest that students who have low self-esteem and high depression are likely to have higher levels of body dissatisfaction, and this, in turn, tends to be associated with greater abnormal eating behavior. Identification of this path has clinical implications in the development of programs to prevent abnormal eating behaviors among young female college students.
