The current study examined the relation between infant sustained attention and infant EEG oscillations. Fifty‐nine infants were tested at 6 (N = 15), 8 (N = 17), 10 (N = 14), and 12 (N = 13) months. Three attention phases, stimulus orienting, sustained attention, and attention termination, were defined based on infants' heart rate changes. Frequency analysis using simultaneously recorded EEG focused on infant theta (2–6 Hz), alpha (6–9 Hz), and beta (9–14 Hz) rhythms. Cortical source analysis of EEG oscillations was conducted with realistic infant MRI models. Theta synchronization was found over fontal pole, temporal, and parietal electrodes during infant sustained attention for 10 and 12 months. Alpha desynchronization was found over frontal, central and parietal electrodes during sustained attention. This alpha effect started to emerge at 10 months and became well established by 12 months. No difference was found for the beta rhythm between different attention phases. The theta synchronization effect was localized to the orbital frontal, temporal pole, and ventral temporal areas. The alpha desynchronization effect was localized to the brain regions composing the default mode network including the posterior cingulate cortex and precuneus, medial prefrontal cortex, and inferior parietal gyrus. The alpha desynchronization effect was also localized to the pre‐ and post‐central gyri. The present study demonstrates a connection between infant sustained attention and EEG oscillatory activities. 相似文献

Previous research has demonstrated that people are happier after spending money on others (prosocial spending) rather than spending on themselves (personal spending). This relationship between prosocial spending and well-being has been proved to be reliable across countries and ages. However, the happiness of recipients has been frequently ignored in past prosocial behavior studies, and only a few studies have explored the effect of givers’ voluntary intention on recipients’ well-being and responses. Considering that the purpose of prosocial spending is to benefit both spenders and recipients, this study attempts to investigate the relationships among gift attractiveness, positive perceived intention, willingness-to-accept (WTA) and subjective well-being (SWB) of recipients in prosocial spending. The results of a large scale survey demonstrate that both gift attractiveness and positive perceived intention are positively related to recipients’ willingness-to-accept. And willingness-to-accept is positively associated with recipients’ SWB. More importantly, willingness-to-accept mediates both the relationship between gift attractiveness and SWB, and the relationship between positive perceived intention and SWB. Some implications for theory and practice are discussed. 相似文献

风险情景中不同成就动机者的冒险行为特征 总被引:8,自引:0,他引:8
采用计算机模拟和问卷的方法,研究不同成就动机的个体在动态情境下的冒险行为。结合成就动机的静态与动态理论,考察具有不同程度的成就动机个体在动态环境中的行为差异。结果发现,在动态情境的初期,可以看到不同成就动机的被试有稳定的偏好:成就动机高的个体偏爱中等难度的任务,成就动机低的个体偏爱较易或者是较难难度的任务;随着行为的动态进行,个体的冒险行为呈现出与静态情境中不同的规律性:成就动机高的个体在初期选择的中等难度的基础上逐渐选择更难的任务;成就动机低的个体在初期选择较易难度任务的基础上也逐渐选择更难的任务;相对于成就动机低的个体,成就动机高的个体会更慢地选择难度高的任务;高成就动机个体出现非典型转换次数显著低于低成就动机的个体。 相似文献

This study examined the multiple components of gender identity (Egan and Perry 2001) and their relationships with psychological adjustment among 201 boys and 160 girls (aged 9 to 12 years) in Mainland China. Boys were found to be more content about their gender but feel more pressure to conform to gender stereotypes than girls. No gender or age differences were found in children’s intergroup bias. Higher gender typicality was related to greater global self-worth, greater social competence, and lower sense of loneliness. However, neither felt pressure nor gender contentment significantly predicted psychological adjustment. These results were compared with findings of previous United States-based studies to highlight the impacts of cultural contexts on gender identity and their effects on adjustment. 相似文献
