Folkbiology meets microbiology: a study of conceptual and behavioral change

Health education can offer a valuable window onto conceptual and behavioral change. In Study 1, we mapped out 3rd-grade Chinese children’s beliefs about causes of colds and flu and ways they can be prevented. We also explored older adults’ beliefs as a possible source of the children’s ideas. In Study 2, we gave 3rd- and 4th-grade Chinese children either a conventional cold/flu education program or an experimental “Think Biology” program that focused on a biological causal mechanism for cold/flu transmission. The “Think Biology” program led children to reason about cold/flu causation and prevention more scientifically than the conventional program, and their reasoning abilities dovetailed with their mastery of the causal mechanism. Study 3, a modified replication of Study 2, found useful behavioral change as well as conceptual change among children who received the “Think Biology” program and documented coherence among knowledge enrichment, conceptual change, and behavioral change.     

Measuring Hong Kong Undergraduate Students’ Attitudes Towards Transpeople

Hill and Willoughby’s (Sex Roles, 53:531–544, 2005) Genderism and Transphobia Scale (GTS), originally developed in Canada, was examined with a Hong Kong sample. Undergraduate students, 82 female and 121 male (total n?=?203), completed a Chinese version of the instrument. Overall scores and factor structure of the Hong Kong sample were compared with Hill and Willoughby’s Canadian data. Gender differences in transphobia were investigated, both in terms of the participants’ gender as well as the gender of the gender variant persons to whom GTS items referred. Transphobia was higher in Hong Kong than in Canada. The factor structure for Hong Kong differed from Canada. Five factors were identified (with a gender effect on Factors II and V). They were: I, Anti Sissy Prejudice; II, Anti Trans Violence; III, Trans Unnaturalness; IV, Trans Immorality; and V, Background Genderism. Hong Kong men were more transphobic than women. Gender variance in men was viewed less favourably than in women.     

The Chinese Personality Assessment Inventory as a Culturally Relevant Personality Measure in Applied Settings

This paper introduces the development of the Cross‐Cultural (Chinese) Personality Assessment Inventory (CPAI) as a culturally relevant measure for personality assessment in collectivistic cultures. In addition to universal personality traits, the CPAI included indigenously derived scales that assessed the relational aspects of personality. We reported three studies that illustrated the usefulness of these indigenous scales in Chinese organizational settings. The Interpersonal Relatedness factor scales on the CPAI contributed additional value beyond scales from the universal factors of Social Potency and Dependability in profiling MBA students at senior‐level positions, in assessing hotel workers’ customer orientation, and in predicting senior executives’ leadership behaviors.     

A model for integrating fixed-, random-, and mixed-effects meta-analyses into structural equation modeling

Meta-analysis and structural equation modeling (SEM) are two important statistical methods in the behavioral, social, and medical sciences. They are generally treated as two unrelated topics in the literature. The present article proposes a model to integrate fixed-, random-, and mixed-effects meta-analyses into the SEM framework. By applying an appropriate transformation on the data, studies in a meta-analysis can be analyzed as subjects in a structural equation model. This article also highlights some practical benefits of using the SEM approach to conduct a meta-analysis. Specifically, the SEM-based meta-analysis can be used to handle missing covariates, to quantify the heterogeneity of effect sizes, and to address the heterogeneity of effect sizes with mixture models. Examples are used to illustrate the equivalence between the conventional meta-analysis and the SEM-based meta-analysis. Future directions on and issues related to the SEM-based meta-analysis are discussed.     

Psychological resilience and dysfunction among hospitalized survivors of the SARS epidemic in Hong Kong: a latent class approach

OBJECTIVE: To examine trajectories of psychological functioning using latent class analysis on a sample of hospitalized survivors of the 2003 severe acute respiratory syndrome (SARS) epidemic in Hong Kong. DESIGN: A longitudinal study of 997 survivors, recruited from among 1,331 individuals hospitalized for SARS, were interviewed at 6, 12, and 18 months after hospitalization. MAIN OUTCOME MEASURES: Psychological and physical functioning at each time point was measured using the 12-item Medical Outcome Study Short-Form Health Survey (SF-12). RESULTS: Four latent classes were identified--chronic dysfunction, delayed dysfunction, recovery, and resilience. All groups had better physical health than the chronic group. Resilient and recovered individuals had greater social support and less SARS-related worry, and resilient individuals were more likely to be male. The resilient group also had greater social support than the delayed group and better physical functioning than the recovered group. CONCLUSION: This study demonstrated that longitudinal outcome trajectories following a major health-threat event in an Asian sample bear close resemblance to prototypical trajectories observed in trauma studies using Western samples. Unique predictors of the trajectories included factors observed in previous studies, such as social support, as well as factors of particular relevance to a major disease outbreak, such as SARS-related worry.     

Helping processes in a mutual aid organization for persons with emotional disturbance.

To date, the notion of helpfulness of group processes has been equivocal in research on self-help groups. This article argues that findings drawn from the participants' subjective appraisals of helpfulness carry meanings different from those drawn from the correlational approach. In a mutual aid organization serving adults with mental health problems, the study found that, whereas universality, self-disclosure, and instillation of hope were the most valued processes, support and catharsis were the strongest correlates of benefits of participation. The authors propose a two-level hierarchy that distinguishes sustaining and beneficial factors. Different sets of factors should constitute the focus of facilitation at different stages of group development.     

殊化信任与泛化信任在人际信任行为路径模型中的作用

该研究探讨不同社会情景下,泛化信任、殊化信任以及可信任性知觉等对信任行为起作用的理论模型。223名工人被试平均年龄24岁。用结构方程模型中的路径分析验证该模型,结果表明,各种拟合指标十分理想。三种交往情景下的人际信任路径模型之间的异同主要表现在：（1）殊化信任在所有情景下对信任行为都有直接而显著的作用;（2）泛化信任则只在与熟人和陌生人交往时才起作用;（3）与目标人物的关系越疏远,对他们作出信任行为时所需要的心理资源也越多。     

Cycloheximide blocks the retention of maternal experience in postpartum rats

Two studies were done to determine the effects of cycloheximide (CYX), a protein synthesis inhibitor, on maternal experience effects in rats. In the first study eight groups received a 2-h maternal experience 36 h after cesarean (c)-section and two groups received no post c-section experience. Among the experienced groups, two received icv injections of CYX or saline (SAL) 30 min before the maternal experience, two received CYX or SAL 10 min after the experience, and two received the injections 24 h after the experience. One inexperienced group received CYX and the other received SAL 36 h after c-section. Tests for maternal behavior occurred 10 days after c-section. CYX was not able to block or disrupt the "acquisition" or expression of ongoing maternal behavior during the 2-h experience phase. However, CYX was able to block the long-term "retention" of a 2-h maternal experience if the drug was present during or immediately after the experience, prior to "consolidation." The second study investigated the effects of CYX administered immediately after the maternal experience on the expression and retention of maternal behavior 4 and 6 days after c-section, to determine whether the hormonally mediated short-onset latencies of the 4-day group would be blocked by CYX. Eight groups of animals were tested for maternal behavior. Four were tested 4 days after c-section and four were tested 6 days after c-section. Within each of these groups two were experienced and two inexperienced; within each experience condition one group received CYX and one received SAL. Day 4 groups exhibited shorter onset latencies than Day 6 groups. There was also a CYX-SAL difference in maternal onset latencies among experienced Day 6 groups but not among Day 4 groups. These data indicate that the blocking effects of CYX can be seen only when hormonal priming of maternal behavior is no longer in evidence.     

The roles of different executive functioning skills in young children’s mental computation and applied mathematical problem-solving

This study investigated the relationships of four executive functioning skills (including verbal working memory, spatial working memory, inhibitory control, and cognitive flexibility) with young children’s mental computation and applied mathematical problem-solving. Two hundred and twenty-five Chinese kindergarteners were tested with a battery of general cognitive, executive functioning and mathematics skills. Results showed that when children’s age, gender, non-verbal intelligence, and listening comprehension skills were controlled, verbal working memory and cognitive flexibility were significant correlates of mental computation, whereas verbal working memory, spatial working memory, and cognitive flexibility were significant correlates of applied mathematical problem-solving. Inhibitory control was not significantly associated with the two domains of mathematics under investigation. The findings highlight the differential roles of different executive functioning skills in early mathematical skills and offer practical implication for helping young children in learning complex mathematical skills.     

Autobiographical memory functions of nostalgia in comparison to rumination and counterfactual thinking: similarity and uniqueness

We compared and contrasted nostalgia with rumination and counterfactual thinking in terms of their autobiographical memory functions. Specifically, we assessed individual differences in nostalgia, rumination, and counterfactual thinking, which we then linked to self-reported functions or uses of autobiographical memory (Self-Regard, Boredom Reduction, Death Preparation, Intimacy Maintenance, Conversation, Teach/Inform, and Bitterness Revival). We tested which memory functions are shared and which are uniquely linked to nostalgia. The commonality among nostalgia, rumination, and counterfactual thinking resides in their shared positive associations with all memory functions: individuals who evinced a stronger propensity towards past-oriented thought (as manifested in nostalgia, rumination, and counterfactual thinking) reported greater overall recruitment of memories in the service of present functioning. The uniqueness of nostalgia resides in its comparatively strong positive associations with Intimacy Maintenance, Teach/Inform, and Self-Regard and weak association with Bitterness Revival. In all, nostalgia possesses a more positive functional signature than do rumination and counterfactual thinking.
