Human psychology and behavior are influenced by culture. Self-construals reflect the individualism-collectivism dimension at the level of individual personality. The current study aimed to explore how self-construals affect subjective well-being (SWB) in China, which has a collectivist culture. Chinese undergraduates (N?=?442) participated in this study. They responded to the self-construal scale, Rosenberg self-esteem scale, collective self-esteem scale and measures of SWB. The results suggested that the type of self-construal significantly predicted SWB. Moreover, an individual’s self-esteem completely mediated the impact of independent self-construal on SWB, whereas interdependent self-construal influenced SWB directly, as well as indirectly though collective self-esteem. In addition, collective self-esteem promoted individual self-esteem, which in turn further stimulated SWB. These findings extend prior reports and shed light on how individual differences in self-construal affect SWB. 相似文献

We propose a latent topic model with a Markov transition for process data, which consists of time-stamped events recorded in a log file. Such data are becoming more widely available in computer-based educational assessment with complex problem-solving items. The proposed model can be viewed as an extension of the hierarchical Bayesian topic model with a hidden Markov structure to accommodate the underlying evolution of an examinee's latent state. Using topic transition probabilities along with response times enables us to capture examinees' learning trajectories, making clustering/classification more efficient. A forward-backward variational expectation-maximization (FB-VEM) algorithm is developed to tackle the challenging computational problem. Useful theoretical properties are established under certain asymptotic regimes. The proposed method is applied to a complex problem-solving item in the 2012 version of the Programme for International Student Assessment (PISA). 相似文献
