On the internal structure of phonetic categories: a progress report

There is growing evidence that phonetic categories have a rich internal structure, with category members varying systematically in category goodness. Our recent findings on this issue, which are summarized in this paper, underscore the existence and robustness of this structure and indicate further that the mapping between acoustic signal and internal category structure is complex: just as in the case of category boundaries, the best exemplars of a given category are highly dependent on acoustic-phonetic context and are specified by multiple properties of the speech signal. These findings suggest that the listener's representation of phonetic form preserves not only vategorical information, but also fine-grained information about the detailed acoustic-phonetic characteristics of the language.     

Level of Aspiration of High and Low Achievers on A Problem-Solving Task

Level of aspiration on a problem-solving task was hypothesized to (a) depend on achievement on a previous problem-solving task, (b) be higher in males than in females, and (c) be related to long-term educational aspirations. College students (28 males and 31 females) were divided into high achievers and low achievers based on their performance on Problem Set A. High achievers made higher estimates for their performance on Problem Set B than low achievers. Males made higher estimates and performed better on Problem Set B than females. However, estimates were not related to students’ long-term educational aspirations. The low achievers improved significantly more than the high achievers lost on Problem Set B. The low achievers also set a positive goal discrepancy whereas the high achievers did not.

     

Groupthink and the space shuttle challenger accident: Toward a quantitative case analysis

Research on historical cases of policy decisions thought to involve groupthink nearly always has been qualitative, rather than quantitative. We propose that observable antecedents and consequences can be used to code incidents in a group's decision process, thereby providing the basis for more rigorous, quantitative analyses. As a first step toward such a quantitative case analysis, we coded statements from the investigative report on the space shuttle Challenger accident as positive or negative instances of the observable antecedents and consequences of groupthink. Positive instances of groupthink were twice as frequent as negative instances. More importantly, during the 24 hours prior to launch the ratio of positive to negative instances increased, then remained high. These results are consistent with the notion that the decision to launch the Challenger involved groupthink and provide a first step toward more rigorous quantitative analysis of historical or current decision processes.     

Perceived regard explains self- esteem differences in expressivity

Baumeister, Tice, and Hutton proposed that individuals with low self-esteem (LSEs) adopt a more cautious, self-protective self-presentational style than individuals with high self-esteem (HSEs). The authors predicted that LSEs' self-protectiveness leads them to be less expressive-less revealing of their thoughts and feelings-with others than HSEs, and that this self-esteem difference is mediated by their perceptions of the interaction partner's regard for them. Two correlational studies supported these predictions (Studies 1 and 2). Moreover, LSEs became more expressive when their perceived regard was experimentally heightened-when they imagined speaking to someone who was unconditionally accepting rather than judgmental (Study 3) and when their perceptions of regard were increased through Marigold, Holmes, and Ross's compliment-reframing task (Study 4). These findings suggest that LSEs' expressiveness can be heightened through interventions that reduce their concerns about social acceptance.     

The contribution of self‐deceptive enhancement to display rules in the United States and Japan

Socially desirable responding was tested as a mediator of American and Japanese college student differences in display rules. Americans endorsed the expression of anger, contempt, disgust, fear, happiness, and surprise more than the Japanese. Americans also exhibited more self‐deceptive enhancement than the Japanese, and self‐deceptive enhancement partially mediated country differences on the endorsement of anger, disgust, happiness, and surprise, but not contempt and fear. These findings highlight the role of self‐deceptive enhancement in contributing to expressive display rules and support the point of view that socially desirable responding is a reflection of one's personality and culture rather than a statistical nuisance.     

Attitudes toward seeking professional psychological help among Chinese students at a UK university

Aim: In this study we aimed to investigate whether Chinese international and British home students at a university in the United Kingdom differed in their attitudes towards seeking psychological help. Method: The total sample comprised 323 participants. Participants completed measures to assess their attitudes toward seeking professional psychological help (recognition of need for psychological help, stigma tolerance, interpersonal openness, confidence in mental health practitioners). Results: Chinese students reported significantly less interpersonal openness than that reported by British students. Contrary to prediction, however, no significant group differences were found on any of the other mental health attitudes (i.e. recognition of need for psychological help, confidence in mental health practitioners or stigma tolerance). Within‐group contrasts also showed that Chinese students reported lower scores on interpersonal openness than on stigma tolerance and confidence in mental health practitioners. In contrast, British participants reported less confidence in mental health practitioners and recognition of the need for psychological help than reported for stigma tolerance and interpersonal openness. Conclusion: The findings highlight the need for a greater understanding of students' cultural inclinations toward mental health issues and cultural attitudes that may hinder and/or facilitate students' access and engagement with psychological services in higher education institutions.     

When social networking is not working: individuals with low self-esteem recognize but do not reap the benefits of self-disclosure on Facebook

The popular media have publicized the idea that social networking Web sites (e.g., Facebook) may enrich the interpersonal lives of people who struggle to make social connections. The opportunity that such sites provide for self-disclosure-a necessary component in the development of intimacy--could be especially beneficial for people with low self-esteem, who are normally hesitant to self-disclose and who have difficulty maintaining satisfying relationships. We suspected that posting on Facebook would reduce the perceived riskiness of self-disclosure, thus encouraging people with low self-esteem to express themselves more openly. In three studies, we examined whether such individuals see Facebook as a safe and appealing medium for self-disclosure, and whether their actual Facebook posts enabled them to reap social rewards. We found that although people with low self-esteem considered Facebook an appealing venue for self-disclosure, the low positivity and high negativity of their disclosures elicited undesirable responses from other people.
