采用学习-测验两任务范式,通过3项实验探讨了社会行为的效价信息对注意捕获的影响。在学习阶段,被试观看具有积极效价的帮助行为(某智能体帮助另一智能体爬山)和消极效价的阻碍行为(某智能体阻碍另一智能体爬山),以及与各自运动特性匹配的无社会交互行为,其目的为建立不同智能体颜色与社会行为效价信息的联结关系。在测验阶段,则分别检验社会行为中的施动方(帮助者和阻碍者)颜色和受动方(被帮助者和被阻碍者)颜色的注意捕获效应。结果发现,消极社会行为中施动方颜色和受动方颜色均更容易捕获注意,而积极社会行为效价信息并没有改变联结特征值的注意捕获效应;且相比于受动方,与消极社会行为效价建立联结的施动方颜色的注意捕获效应更强。该结果提示,存在消极社会行为效价驱动的注意捕获,且消极的效价信息与卷入社会行为所有个体的特征建立联结,但该联结中施动方物理特征具有更高的注意优先性。这一发现暗示,声誉信息与对社会交互行为的整体表征可能综合作用于对社会交互事件的注意选择。 相似文献

We have a new understanding on a unified fracture criterion based on two kinds of strain energy density. A definite expression which is a function of Poisson’s ratio to describe a crucial parameter in the unified fracture criterion is derived. The critical value of Poisson’s ratio between brittle and ductile materials can be derived as 2/7 which is verified by experimental data. Besides, the effect of Poisson’s ratio on the fracture loci in stress spaces is studied using unified fracture criterion. It is found that the decrease in Poisson’s ratio increases the asymmetry of fracture loci between tensile stress states and compressive stress states in principal stress spaces and between Lode parameters are 1 and ?1 in deviatoric-stress spaces. In addition, stress triaxiality has a great effect on the fracture behaviour with different Poisson’s ratios. 相似文献

Ecological view of human development calls for an investigation of multiple contexts surrounding children. In South Korea, traditional Confucianism and recent technological advancements serve as influential social and cultural contexts that affect parent–child relations and child development. High levels of parental control and strong emphasis on academic achievement have long been distinctive features of Korean parenting practices, which are attributable to Confucian values. Additionally, Korean children’s mobile phone dependency (MPD) has become a growing concern, as South Korea developed as an IT powerhouse. Combined, these contexts resulted in high parental control of children’s mobile phone use, so that such electronic devices would not hinder learning and achievement. Effects of high parental control on children’s MPD and their school life, however, have yet to be discovered. We hypothesized, that, unlike parents’ intentions, psychological control is more likely to increase MPD and disrupt school life. To examine this research model, we made use of the first and third wave data from Korea Children and Youth Panel Survey. Participants were 2378 children (52.2 % boys) of the same age of 10 in the first wave. After multiple imputation for missing values, hierarchical logistic regression followed to examine the mediational model. The results verified the hypothesized model, showing significant adverse influence of psychological control on MPD, self-regulated learning and school adjustment. MPD fully mediated the effect of psychological control on self-regulations, while partially mediating the effects on school adjustment. Implications for Korean parents with regard to supporting children’s psychological autonomy was discussed. 相似文献

African American youth, especially those who live in low-income communities, are at increased risk for experiencing higher juvenile justice involvement, poorer mental health, low school engagement, higher illicit drug use, and STIs, relative to their higher income peers and those from other ethnic backgrounds. However, few studies have examined the relationship between family stressors and these multiple youth concerns. This study examines the relationship between family stress (i.e., having an adult in the home with a history of mental illness, substance use, and incarceration) and youth concerns such as substance use, mental health challenges, low school engagement, juvenile justice involvement, and STI risk behaviors. A total of 638 African American adolescents living in predominantly low-income, urban communities participated in the study by completing self-report measures on the above constructs. Logistic regressions controlling for age, gender, socioeconomic status, and sexual orientation indicated that adolescents who reported higher rates of family stress were significantly more likely to report mental health problems, delinquent behaviors, juvenile justice involvement, drug use, risky sex, and lower school engagement factors. Findings suggest that attending to the developmental concerns of youth also requires addressing the needs of the family unit. 相似文献
