Family well-being is valued more than personal well-being: A four-country study

Well-being is recognized as a fundamental human goal and a universal human aspiration. However, some cross-country studies suggest that the desirability of the most often studied concept of well-being—personal life satisfaction—varies across countries, and we know little about the desirability of other types of well-being. Extending this novel area of research, we argue that focusing on the family (as compared to the individual) as the subject of well-being may be another important distinction in how well-being is conceptualized and valued. With data collected in four countries that tend to occupy different positions in rankings of personal life satisfaction (i.e., Canada, Colombia, Japan, and Poland), we document that, irrespective of cultural context, family well-being is valued over personal well-being. These findings suggest that policy makers and scientists may need to pay more attention to family well-being than they currently do.

     

Event-related Desynchronization of Mu Rhythms During Concentric and Eccentric Contractions

The purpose of this study was to compare the electroencephalographic (EEG) patterns and reaction times (RTs) of muscle activation between concentric and eccentric biceps brachii contractions under the RT paradigm and to evaluate how the EEG patterns and RTs changed with practice. Sixteen subjects performed 3 sets of 30 repetitions of submaximal voluntary concentric and eccentric biceps contractions. RT, event-related desynchronization (ERD) patterns of mu rhythm onset, and ERD amplitudes were selectively analyzed. Mental demand decreased as familiarity with the motor action increased due to practice regardless of contraction type. However, the 2 types of muscle contractions still have differences in brain activity regardless of decreased mental demand: eccentric contractions require earlier preparation than concentric contractions.     

Religiosity and Healthy Lifestyle Behaviours in Malaysian Muslims: The Mediating Role of Subjective Well-Being and Self-Regulation

Past research on healthy lifestyle behaviours has been primarily conducted within Western or Judeo–Christian contexts, while non-Western or Muslim contexts remain under-represented. This study examined predictors of healthy lifestyle behaviours (religiosity, goal-setting, impulse control, and subjective well-being) in Malaysian Muslims and explored the mechanisms underlying the relationship between religiosity and healthy lifestyle behaviours. Self-report survey responses from 183 healthy adults (M _age = 28.63 years, 18–50 years) were analysed using regression and multiple mediation analyses. The results indicated that subjective well-being emerged as the strongest predictor, followed by goal-setting. Furthermore, subjective well-being and goal-setting mediated the religiosity–healthy lifestyle behaviour relationship. The findings provide guidance for future health-promoting interventions.     

Moderating Effects of Prevention-Focus on the Paths from Two Insecure Attachment Dimensions to Depression

The present study investigated the moderating effects of prevention-focus on the paths from the dimensions of insecure attachment (attachment avoidance and attachment anxiety) to depression. Two hundred twenty eight Korean college students completed the Experience in Close Relationship – Revised Scale; the Regulatory Focus Strategies Scale; and the Center for Epidemiologic Studies Depression Scale. Results revealed a significant moderating effect for prevention-focus on the path from attachment avoidance to depression, but not on the path from attachment anxiety to depression. They further suggest that different interventions are needed for different combinations of persons' insecure attachment dimensions and levels of prevention-focus. Counseling implications and suggestions for future research are discussed.     

A Process Model of Goal Orientation and Feedback Seeking

This study investigated antecedents of seeking different types of feedback. Individual differences in goal orientation and cost and value perceptions were proposed as antecedents of seeking different types of feedback. We hypothesized that 4 dimensions of cost and value perceptions of feedback seeking (expectancy value, appraisal value, ego cost, and self-presentation cost) are related to an individual's goal orientation. Furthermore, moving beyond a focus on the frequency of feedback seeking, we proposed that the perceptions of costs and values of feedback seeking influence the preference for and choice among 4 distinct feedback types (diagnostic, normative, assurance, and no feedback). A total of 240 students participated in a computer-simulated work setting. Results were largely consistent with the hypotheses; each goal orientation had a unique pattern of relations with the perceptions of costs and values. Cost and value perceptions, in turn, influenced preference and choice for feedback type. The theoretical implications of the research are discussed.     

Social identity,attribution, and emotion: Comparisons of Americans,Korean Americans,and Koreans

The social identity of another person, in addition to the social identity of self, can be an important factor affecting the types of attribution judgments and emotions that individuals indicate for the other person. In April 2007, the perpetrator of the shooting incident on the Virginia Tech University campus was identified as a person who emigrated to the USA from Korea at a young age. The current study compared non‐Korean Americans, Korean Americans, Koreans in the USA, and Koreans in Korea in terms of their attributions and emotions concerning the perpetrator and the shooting incident. Participants were asked to indicate (1) the extent to which they attributed the cause of the incident to either American society or the perpetrator, (2) their emotions (e.g., upset), and (3) the extent to which they categorized the perpetrator as an American, a Korean American, or a Korean. The results indicated that non‐Korean Americans were most likely to attribute the cause of the incident to the perpetrator as opposed to American society. Non‐Korean Americans, Korean Americans, and Koreans in the United States had more negative emotions (e.g., unhappy, sad, and upset) about the incident than Koreans in Korea did. The results also indicated that individuals differed in their attributions and emotions depending on how they categorized the perpetrator. For example, categorizing the perpetrator as being a Korean was positively related to Americans’ tendency to hold the perpetrator responsible, while categorizing the perpetrator as being an American was negatively related to the tendency to hold the perpetrator responsible among Koreans in Korea. The findings may imply that social identity theory, intergroup emotion theory, and cultural orientations (e.g., individualism and collectivism) can provide insights into people's reactions to a tragic incident.     

A Religious Profile of American Entrepreneurs

The entrepreneur is a celebrated figure in American society. These innovative risk‐takers hold an influential place in the economy and in popular culture. Substantial research has gone into identifying characteristics associated with these individuals, but research on entrepreneurs and religion is surprisingly sparse and inconsistent. Using national survey data, we examine religious affiliation, belief, and behavior for Americans who have started or are trying to start a business. American entrepreneurs appear no different than nonentrepreneurs in religious affiliation, belief in God, or religious service attendance. They do tend to see God as more personal, pray more frequently, and are more likely to attend a place of worship that encourages business activity. A discussion of implications concludes the research note.     

Effector Independence

Although effector independence is predicted in a number of theoretical perspectives, it has received only moderate empirical support. The authors conducted 3 experiments to determine the extent to which simple motor sequences are effector independent. A measurement scheme that partitioned response errors into independent error measures attributable to the relative structure of the response and the force-time scaling of that structure was used in the analysis of the present experiments. The results indicated that the relative structure of the response could be effectively transferred from one limb to the contralateral limb (Experiment 1), to a different muscle group on the same limb (Experiment 2), and from a static to a dynamic version of the task (Experiment 3). The ability to scale force was effector dependent, however, and the force scaling was relatively ineffective when an unpracticed limb was used. Although participants (Ns = 20, 24, and 20, respectively, in Experiments 1, 2, and 3) were effective in transferring the movement structure from a static to a dynamic version of the task, they were not very effective in transferring from a dynamic to a static version of the task. The transfer difference appeared to be related to the information that was available to support performance of the dynamic version of the task, which was not available in producing the static version.
