Malaysia is a multi‐ethnic country with Malay, Chinese and Indian being the dominant ethnic groups. This paper investigates the three ethnic cultures in Malaysia by examining the individual‐level values of managers and professionals. Based on 528 responses to a Schwartz Value Survey (SVS) questionnaire, the paper identifies partial convergence of the value systems of Malay, Chinese and Indian people. It was found that the three ethnic groups do not differ significantly in the individualistic value dimensions of Self‐enhancement and Openness‐to‐change. However, Malays are found to be more conservative and less self‐transcendent than Chinese or Indians, while Chinese and Indians attribute the same importance to these two sets of values.  相似文献

For experience products, such as apparel, sensory‐enabling presentations that provide a sense of tactile experience have been suggested as an effective strategy to reduce perceived risk and increase the likelihood of a pleasurable shopping experience. Using functional Magnetic Resonance Imaging (fMRI), we investigated whether sensory‐enabling presentations, specifically, image zooming and rotation videos, would evoke different cognitive and affective brain functions during product evaluation and purchase decision processes. The results suggested that whereas image zooming may evoke more visual perception in the product evaluation process, the rotation view evokes more mental imagery, pleasure, and reward anticipation during the purchase decision process.

Infant social withdrawal is a risk factor for non-optimal child development; thus, it is important to identify risk factors associated with withdrawal. In a large community sample (N = 19,017), we investigate whether symptoms of maternal and partner postpartum depression (PPD; measured with the Edinburgh Postnatal Depression Scale) and prematurity are predictors of infant social withdrawal (measured with the Alarm Distress Baby Scale). Withdrawal was assessed at 2–3, 4–7 and 8–12 months postpartum. Linear regressions showed that prematurity predicted higher infant social withdrawal at all time points, and maternal symptoms of PPD were positively associated with withdrawal at 2–3 months. Logistic regressions showed that odds for elevated social withdrawal were increased with elevated levels of maternal symptoms of PPD at 2–3 and 8–12 months. Partner's symptoms of PPD were not associated with withdrawal. Future studies should investigate how PPD symptoms and prematurity may impact the individual development of social withdrawal.  相似文献

Whether teachers maintain their expectation bias for students over time is crucial for understanding self-fulfilling prophecy effects. However, the stability of teacher expectation bias has been largely ignored in the literature. We examined the stability of teacher expectation bias across a sample of teachers and the change trajectories of teacher expectation bias across high-, medium-, and low-expectation teacher groups across all teachers and in the curriculum areas of mathematics, Chinese, and English. Our analyses were based on two-year longitudinal data with four time points from 567 Chinese senior high school students and their 50 teachers. The results showed that across all teachers, teacher expectation bias at the individual student level was dynamic over time. That is, teachers seemed to adjust their initial expectation bias in the first few months but then maintained the adjusted expectation bias afterwards. However, when students moved from Grade 11 to Grade 12 (the last year of high school), teachers seemed to change their expectation bias again. The evidence from HLM analyses further supported these results. That is, all the high- and low-expectation teachers alleviated their initial expectation bias significantly in the first six months and then adhered to their adjusted expectation bias. However, when students moved to the last year of high school, some high- and low-expectation teachers’ expectation biases were volatile again. Nevertheless, most high- and low-expectation teachers (except for Chinese low-expectation teachers) tended to either over-estimate or under-estimate their students across two school years. Further, compared to Chinese and mathematics teachers, English teachers’ biases seemed to be even more stable. Our findings suggested that some teachers consistently over- or under-estimated their students over an extended time period and this could have implications for student outcomes.

Historically, parenting has been constructed hierarchically; however, contemporary parenting models frequently emphasize parenting as relationship (Siegel & Hartzell [2004] Parenting from the inside out: How a deeper self‐understanding can help you raise children who thrive; Tuttle, Knudson‐Martin, & Kim [2012] Family Process, 51, 73–89). Drawing on interviews with 20 North American born second‐generation Korean–American mothers and their partners, and sensitized by TP‐CRO, a social constructionist framework for conceptualizing parent–child relational orientations, this grounded theory analysis identified three main processes that facilitate relational connection as a parenting orientation rather than the rule‐directed approach historically associated with first‐generation immigrant Asian families. These include: (a) emphasizing dominant culture values; (b) inviting open communication; and (c) promoting mutuality. Results also show how parents integrate collectivist cultural values of their first generation immigrant parents' traditional culture into North American parenting ideals with which they primarily identify. The study demonstrates the usefulness of the TP‐CRO for understanding parent–child relationships within multicultural parenting contexts and offers suggestions for working with second‐generation Korean families.  相似文献

The current work sought to test the moderating role of a multicultural ideology on the relationship between categorisation salience and ingroup bias. Accordingly, in one experimental study, we manipulated categorisation salience and the accessibility of a multicultural ideology, and measured intergroup attitudes. Results show that categorisation salience only leads to ingroup bias when a multiculturalism (MC) ideology is not made salient. Thus, MC ideology attenuates the negative effects of categorisation salience on ingroup bias. These results pertain to social psychology in general showing that the cognitive processes should be construed within the framework of ideological contexts.  相似文献

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities.  相似文献

Individual variations in the way people respond to sensory stimuli can sometimes lead to maladaptive representations of the world. Indeed, sensory responsiveness profiles were found to be associated with mood symptoms such as depression and anxiety. The goal of the current study was to investigate whether attachment orientations can account for the relationship between sensory responsiveness profiles and anxiety symptoms. Participants (N = 194) completed a battery of questionnaires assessing sensory responsiveness profiles, attachment orientations, and anxiety symptoms. As expected, various associations between sensory responsiveness profiles and anxiety symptoms were accounted for by attachment anxiety and avoidance. We suggest a possible causal path, in which early‐developing sensory responsiveness profiles lead to attachment insecurities, which in turn may lead to mood symptoms such as anxiety.  相似文献
