Working memory components that predict word problem solving: Is it merely a function of reading,calculation, and fluid intelligence?

The purpose of this study was to assess whether the differential effects of working memory (WM) components (the central executive, phonological loop, and visual–spatial sketchpad) on math word problem-solving accuracy in children (N?=?413, ages 6–10) are completely mediated by reading, calculation, and fluid intelligence. The results indicated that all three WM components predicted word problem solving in the nonmediated model, but only the storage component of WM yielded a significant direct path to word problem-solving accuracy in the fully mediated model. Fluid intelligence was found to moderate the relationship between WM and word problem solving, whereas reading, calculation, and related skills (naming speed, domain-specific knowledge) completely mediated the influence of the executive system on problem-solving accuracy. Our results are consistent with findings suggesting that storage eliminates the predictive contribution of executive WM to various measures Colom, Rebollo, Abad, & Shih (Memory & Cognition, 34: 158-171, 2006). The findings suggest that the storage component of WM, rather than the executive component, has a direct path to higher-order processing in children.     

Age-related positivity enhancement is not universal: older Chinese look away from positive stimuli

Socioemotional selectivity theory postulates that with age, people are motivated to derive emotional meaning from life, leading them to pay more attention to positive relative to negative/neutral stimuli. The authors argue that cultures that differ in what they consider to be emotionally meaningful may show this preference to different extents. Using eye-tracking techniques, the authors compared visual attention toward emotional (happy, fearful, sad, and angry) and neutral facial expressions among 46 younger and 57 older Hong Kong Chinese. In contrast to prior Western findings, older but not younger Chinese looked away from happy facial expressions, suggesting that they do not show attentional preferences toward positive stimuli.     

Motivational changes in response to blocked goals and foreshortened time: testing alternatives to socioemotional selectivity theory

Socioemotional selectivity theory contends that when people perceive time as limited, they prioritize emotionally meaningful goals. Although empirical support for the theory has been found in several studies, 2 alternative explanations for the pattern of findings remain: (a) emotional goals are pursued by default because nonemotional goals are blocked, and (b) emotional goals are pursued in search of emotional support rather than emotional meaning. This study tested these alternatives by examining social goals in response to blocked goals and foreshortened time. Findings reveal distinct motivational patterns, as reflected in social preferences and self-reported social goals, in response to the 2 types of constraints.     

Preschoolers' understanding of knowing-that and knowing-how in the United States and Hong Kong

Two experiments on preschoolers' understanding of the effects of exposure on knowing-that and knowing-how were conducted with 3-, 4-, and 5-year-old children (N=388) in 2 locations: a small midwestern city in the United States and a suburban area of Hong Kong, China. By using both English- and Chinese-speaking samples, the authors examined differences in children's understanding of knowing-that and knowing-how as well as the impact of different types of linguistic markers on the understanding of these concepts. Across both studies, in both locations, and for judging the knowledge of self or of others, children's understanding for knowing-that preceded their understanding for knowing-how. Implications of these findings both for universal patterns of theory-of-mind development and for how culture may impact on that development are discussed.     

Clothing interest among Chinese adolescent girls in Hong,Kong in relation to socioeconomic status

A sample of 358 girls in senior secondary school completed the measures assessing importance of clothing and socioeconomic status. A principal component analysis indicated a 3-factor solution that explained 51.3% of the total variance in scores on the Creekmore Importance of Clothing Questionnaire. The factors were named Self-enhancement. Experimentation, and Conformity. A series of one-way analyses of variance showed that higher socioeconomic status might account for greater experimentation with clothing.     

Age differences in social preferences among Taiwanese and Mainland Chinese: the role of perceived time

Socioemotional selectivity theory holds that as people recognize the inevitable constraint of time imposed by mortality, their social goals change, motivating them to limit social contacts to those with whom they are emotionally close. This theory was tested among Taiwanese and Mainland Chinese. As predicted, results showed that older adults (aged 60-90 years) in both cultures were more likely than younger adults (aged 18-30 years) to prefer familiar social partners who were most likely to provide emotionally close social interactions. Mainland Chinese, who as a group have shorter actuarial life expectancy, were more likely to prefer familiar social partners than were Taiwanese. These age and cultural differences were eliminated when differences in perceived time were statistically controlled for.     

Searching for Happiness: The Importance of Social Capital

After four decades of research, scholars of happiness continue to debate its causes. While it is generally agreed that a combination of internal and external factors play a role, predicting happiness well remains a challenge. Recent research has proposed that social capital may be a vital factor that has been overlooked. This paper attempts to address that omission. According to Coleman’s (1988) seminal work, three dimensions of social capital exist: (1) trust and obligations, (2) information channels, and (3) norms and sanctions. Using bootstrap hierarchical regression on data from the Canadian General Social Survey of Social Engagement Cycle 17 (2003), we identified blocks of social capital variables described by Coleman, as well as an additional factor of belongingness. Even after controlling for major demographic and individual characteristics, the majority of these blocks show significant relationships with happiness. Our findings support social capital as an important piece in predicting happiness.     

Changes in peripheral social partners and loneliness over time: the moderating role of interdependence

We examined the relationships between age, changes in the number of peripheral partners, and changes in loneliness over 2 years among 365 Hong Kong Chinese aged 18-91 years. We also tested the moderating role of interdependent self-construal in the relationships. Results showed that the well-documented negative association between age and number of peripheral partners over time was only significant for individuals with low and medium interdependence but not for those with high interdependence. Moreover, only older and middle-aged adults high in interdependence benefitted from having more peripheral social partners by showing decreased loneliness in the 2-year interval.
