The Association Between Age and Ethics-Related Issues in Using Social Media for HIV Prevention in Peru

Little research has focused on the ethical issues around using social media for HIV prevention in low- and middle-income countries, such as Peru. This study surveyed participants from the HOPE social media HIV intervention in Peru to assess their experiences and perceptions of ethical issues in the study and the impact of age on their experiences and perceptions. This study found that, compared to younger participants, older participants were more likely to express higher levels of understanding of the consent form and trust that other participants were real. Older participants also reported being less likely to benefit from learning about their HIV status. Findings suggest that age plays a role in participants’ experiences in a social-media-based HIV intervention.     

Dimensions of distress tolerance and the moderating effects on mindfulness-based stress reduction

Background and Objectives: This study examined the relationship between distress tolerance and psychosocial changes among individuals participating in Mindfulness-Based Stress Reduction (MBSR). The objective of the analysis was to discern whether individuals with lower distress tolerance measured before MBSR showed larger reductions in perceived stress following MBSR. Design and Methods: Data were collected from a sample of convenience (n?=?372) using a quasi-experimental design. Participants completed self-report measures immediately prior to course enrollment and following course completion. Results: Perceived stress, distress tolerance, and mood states showed favorable changes from pre- to post-MBSR in the current study. Baseline distress tolerance significantly moderated reductions on perceived stress, supporting the primary hypothesis that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress following MBSR. For a one-unit increase on the self-reported baseline Distress Tolerance Scale, reported perceived stress scores decreased by 2.5 units (p?Conclusions: The finding that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress may offer hints about who is most likely to benefit from MBSR and other mindfulness-based treatments. Identifying moderators of treatment outcomes may yield important benefits in matching individuals to treatments that are most likely to work for them.     

Quality of Life and Recycling Behaviour in High-Rise Buildings: A Case in Hong Kong

Many researchers, environmentalists and economists have made tremendous efforts to enable polices and measures for waste recycling, to improve the quality of the public living environment and to achieve a better quality of everyday life. This study examined the quality of life (QOL) in high-rise buildings in relation to sustainability. It investigated household recycling behaviour and explored the QOL factors that affect such behaviour. Two models based on different types of recycling behaviour were estimated: 1) a model for the use of public recycling facilities (UPRF) and 2) a model for the use of private recycling sectors (UPRS). Data were collected through a survey of 505 residents in two old districts of Hong Kong. The assessment of QOL included consideration for the physical settings, the socio-demographic variables and the respondents’ attitudes on recycling and living environments. The research methods involved questionnaires and interviews. Correlations and multiple regression analyses were conducted to interpret the data collected through the questionnaires. The findings indicated that UPRF can be significantly predicted by physical settings and by satisfaction with the location of facilities, with the residents’ participation and with the quality of the neighbourhood and accommodation. UPRS can be significantly predicted by housing type, income and the availability of private recycling sectors. These findings also indicate some directions for researchers and policymakers to consider. These directions concern how environments and public facilities should be designed to encourage sustainable behaviour and enable a better QOL without compromising environmental sustainability.     

Investigating sexual harassment in online video games: How personality and context factors are related to toxic sexual behaviors against fellow players

Online video games are social spaces for players from around the world. They use this space to form communities, relationships, and identities. However, gaming communities are not always welcoming, and some are even perceived as being “toxic.” A prevalent issue is online sexual harassment, which is keeping many women from participating in the gaming community. Research on the factors contributing to the problem is limited, though. The present study replicates and expands previous research, using a sample of 856 online gamers. The study supports earlier findings that found hostile sexism and social dominance orientation as predictors of sexual harassment perpetration in online video games. In addition, we expanded the previous research with additional predictors: machiavellianism, psychopathy, and gamer identification predicted higher sexual harassment perpetration. Our results have implications for the gaming community's role in curtailing sexual harassment and making itself a more inclusive community.     

Motivated cultural cognition: the impact of implicit cultural theories on dispositional attribution varies as a function of need for closure

The authors propose that need for closure (NFC) leads attributors to respond to an ambiguous social event by increasing reliance on implicit theories received from acculturation. Hence, the influence of NFC should be shaped by chronically accessible knowledge structures in a culture, and, likewise, the influence of culture should be moderated by epistemic motives such as NFC. The specific hypotheses drew on past findings that North American and Chinese attributors possess differing implicit social theories, North Americans conceiving of individuals as autonomous agents and Chinese conceiving of groups as autonomous. The present studies found the predicted pattern that among North American participants, NFC increased attributions to personal but not group dispositions. Among Chinese participants, NFC increased attributions to group but not personal dispositions. The findings are discussed in light of an emerging dynamic account of culture and cognition.     

Specificity of auditory implicit and explicit memory: Is perceptual priming for environmental sounds exemplar specific?

Previous research (Stuart & Jones, 1995) has suggested that identification of environmental sounds may be mediated by abstract sound recognition units. This article reports the results of four repetition priming experiments that find evidence to the contrary. Participants attempted to identify environmental sounds from the initial sound stems (Experiments 1 and 2) or when the sounds were embedded in white noise (Experiments 3 and 4). Repetition of an identical exemplar sound led to more priming than did exposure to a different exemplar, provided that the perceptual difference between the two different exemplars was sufficiently large. Such an exemplar specificity effect was independent of the depth of prior encoding. A similar exemplar specificity effect was also found in explicit stem-cued recall (Experiments 1 and 2) and recognition (Experiment 3). Depth of encoding dissociated performance on tests of repetition priming and explicit memory. These results suggest that a significant amount of specific information is remembered, both implicitly and explicitly, to characterize individual exemplars of a sound category.     

Group-serving attributions across intergroup contexts: Cultural differences in the explanation of sex-typed behaviours

This research attempted to integrate Tajfel's (1978) social identity theory with self-presentational concerns by exploring attributions about perceived group differences in behaviour. As such, it dealt with group-level rather than individual-level attributions, exploring whether bias in making such verbal attributions varied as a function of the interviewer's group identity and the presence of an ingroup audience. Undergraduate men and women at The Chinese University of Hong Kong rated the appropriateness of ingroup-favouring and outgroup-favouring explanations for male-typed and female-typed behaviors in a face-to-face interview. A group-serving bias was found for female-typed behaviours, but only when the same-sex audience was absent. A conceptual replication of the experiment was run in the United States to examine the possible cultural basis for the Chinese moderation of favouritism in the audience condition. The group-serving bias was more robust for the American undergraduates, extending across male- and female-typed behaviours and also across audience conditions, It was argued that these cultural differences in attributional bias appear to reflect the strength of the movement for women's liberation and norms surrounding the avoidance of conflict in the United States and Hong Kong.     

When modesty fails: The social impact of group-effacing attributions following success or failure

This study explored how group members perceived a fellow group member who made either group-serving or group-effacing attributions following success or failure. Forty male undergraduates from the Chinese University co-operated in pairs with a confederate on a demanding group task. After learning that their group's performance had exceeded or failed to meet a standard, the subjects heard their confederate-partner make group-effacing or group-serving attributions. As predicted, subjects evaluated the group-serving partners more highly (p < 0.05). Preference for group-enhancing members was discussed as a pancultural response arising from the interdependence of group members. Given the process of social categorization, group members rise or fall together and are therefore socialized to support their group.     

拥挤、抢食对自发性高血压大鼠发病的影响及作用机制的探讨

社会、心理压力与疾病的发生、发展及转归有着密切的联系。而社会、心理压力为什么会导致一些心身疾病的发生?为什么可使一些疾病加重?尚无满意答案。本文选用自发性高血压大鼠(SHR),在实验室应激的条件下,对比观察了动物的血压,并对其作用机制进行了初步探讨。发现:心理紧张状态可以导致有高血压遗传素质的SHR提前发病,而且可使病情不断加重;应激后SHR血浆神经递质(NE.E)和神经肽类物质(VIP)均明显增高。表明原发性高血压病的发生、发展与社会心理因素关系密切。     

Recipient need and efficacious caring as moderators of helpers’ reactions to rejection and acceptance

Two experiments support and extend the thesis that rejection of their help is stressful for would-be helpers, and that it leads to “damage controlling” reactions whose eventual goal is to restore their self-image of being efficacious at helping and caring. American college students were invited to offer help, if they wished, to a poorly performing (confederate) recipient who then either rejected or accepted it. Rejected helpers expressed relatively negative affect, biased postdictions of low acceptance, claims of low decision control, recipient- and self-devaluation, and less desire for further association. Individual differences in self-perceived “efficacious caring” and manipulated level of recipient need were shown to moderate some of these outcome reactions. Violated expectancy of acceptance was shown to mediate some of these reactions. Studies were cited showing the generalizability of these findings and theoretical framework to applied contexts and across cultural settings.
