Previous research suggests that there is a relationship between social contexts (e.g., economic growth, engagement in wars) and motives within populations. In particular, high achievement motive is associated with subsequent economic growth, which in turn increases power motive. Increased national achievement and power motives have been argued to precede social changes that lead to decreased affiliation motives, and engagement in wars. The present study aimed to examine differences in achievement, power, and affiliation motives between 266 college students in China (a nation with sustained high economic growth) and 255 college students in the USA (a nation with previously strong but now slowing economic growth, and engaged in war). Analysis of personal strivings suggested that Chinese college students showed significantly higher levels of achievement motive than the American college students, but American college students showed significantly higher levels of affiliation motive than Chinese college students. Overall, males exhibited higher achievement motivation than females. No significant interaction effects were found for gender by location for any of the three motives. The findings are discussed in relation to previous research. 相似文献
This study investigated whether young children make strategic decisions about whether to lie to conceal a transgression based on the lie recipient's knowledge. In Experiment 1, 168 3- to 5-year-olds were asked not to peek at the toy in the experimenter's absence, and the majority of children peeked. Children were questioned about their transgression in either the presence or absence of an eyewitness of their transgression. Whereas 4- and 5-year-olds were able to adjust their decisions of whether to lie based on the presence or absence of the eyewitness, 3-year-olds did not. Experiments 2 and 3 manipulated whether the lie recipient appeared to have learned information about children's peeking from an eyewitness or was merely bluffing. Results revealed that when the lie recipient appeared to be genuinely knowledgeable about their transgression, even 3-year-olds were significantly less likely to lie compared with when the lie recipient appeared to be bluffing. Thus, preschool children are able to make strategic decisions about whether to lie or tell the truth based on whether the lie recipient is genuinely knowledgeable about the true state of affairs. 相似文献
Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded during a words-categorization task with stimuli presented in the auditory-visual modality. In the experiment, congruency of the visual and auditory stimuli was manipulated. Results showed that within the window of about 180-210 ms post-stimulus more positive values were elicited by category-congruent audiovisual stimuli than category-incongruent audiovisual stimuli. This indicates that the late frontal-central audiovisual interaction is related to audiovisual integration of semantic category information. 相似文献
Life satisfaction is a key indicator of children’s healthy development. Although the developmental changes of life satisfaction during adolescence have been investigated, the developmental trajectories of life satisfaction and related predictors during childhood remain unclear. Thus, the current study aimed to identify the developmental trajectories of life satisfaction covering the period from middle to late childhood as well as to examine the predictive roles of environmental factors (i.e., family dysfunction and basic psychological needs satisfaction at school), personality factors (i.e., neuroticism and extraversion), and their interactions in these developmental trajectories. An accelerated longitudinal design was used with Chinese elementary school students (N?=?1069, 45.8% girls, Mage?=?9.43, SD?=?0.95) of 3 cohorts (grade 3, grade 4, and grade 5) on 4 occasions at 6-month intervals. Growth mixture modeling analyses revealed three distinct trajectories of life satisfaction: “High-Stable” (88.8%), “High-Decreasing” (6.8%), and “Low-Increasing” (4.4%). Multivariate logistic regression analyses revealed that family dysfunction and neuroticism served as risk factors for adverse developmental trajectories of life satisfaction; whereas basic psychological needs satisfaction at school served as a protective factor. Furthermore, the interaction between family dysfunction and extraversion suggested that higher levels of extraversion buffered children against the negative effect of family dysfunction on the development of life satisfaction. The identification of three heterogeneous trajectory groups of children’s life satisfaction and key personality and environmental predictors associated with the trajectories suggests that specific interventions need to be tailored to the unique characteristics of the relevant trajectory groups.
Abundant research conducted in Western contexts has shown that biological risk factors such as low resting heart rate (HR) might be related to childhood aggression. However, it was unclear (1) how resting HR, as well as other markers of cardiac functions such as resting vagal tone, may be related to subtypes of aggression such as reactive and proactive aggression, and (2) whether the HR-aggression relation can be replicated in non-Western contexts. Therefore, this study examined the concurrent and prospective relations between resting HR, vagal tone, and Chinese children’s reactive and proactive aggression. Participants were 183 children (M age?=?7.64 years, 91 girls) recruited from an elementary school in Zhenjiang, PRC. Children’s resting HR and vagal tone were assessed in the second grade (T1). Teachers rated children’s reactive and proactive aggression in the second (T1) and fourth grade (T2). Results showed that lower resting HR at T1 was associated with higher reactive and proactive aggression at T1 and T2, and higher vagal tone was associated with lower HR, which in turn was related to higher reactive and proactive aggression at T1 and T2. Lower vagal tone was directly related to higher reactive but not proactive aggression at T1 and T2, whereas lower HR was related to higher reactive aggression at T2 for children with low or moderate vagal tone but was not for children with high vagal tone. These psychophysiological findings from a non-Western context add additional support for both similarities and differences between reactive and proactive aggression in childhood. 相似文献
