不同学习方式下归类不确定时的特征推理

采用学习-迁移模式, 探讨了同时学习和继时学习两种方式下归类不确定时的特征推理。共包括2个实验, 其中实验1探讨了固定学习轮次的情况, 实验2探讨了固定学习正确率的情况。实验结果表明：同时呈现类别要素的同时学习方式下, 被试习得序列式的单类别表征(原型表征), 在归类不确定时的特征推理中按照“单类的Bayesian规则”进行特征推理, 即P(j\F) =P(k\F)·P(j\k); 相继呈现类别要素的继时学习方式下, 被试习得并列式的多类别表征, 在归类不确定时的特征推理中按照“理性模型”进行推理, 即 P(j\F) =Σk P(k\F)·P(j\k)。     

When Leaders Are Seen as Transformational: The Effects of Organizational Justice1

In 2 studies, we attempted to make a first step toward integrating the literature on transformational leadership and organizational justice. We examined the extent to which justice affects perceptions of transformational leadership. We predicted that especially interactional justice should have strong effects. Study 1 was a vignette study (N = 100) in which distributive, procedural, and interactional justice were manipulated orthogonally. As expected, only interactional justice affected transformational leadership perceptions. Study 2 replicated these results in an organizational field study (N = 257). Distributive and procedural justice affected perceptions of transformational leadership, but when interactional justice was entered in the regression equation, their effects disappeared. Implications for integrating the literature on transformational leadership and organizational justice are discussed.     

Models and Reality: When Science Tackles Sex

Through a discussion of the way science has been used to address intersexuality, I explore an idea about how to understand science as objective and yet influenced by social, historical, and cultural factors. I propose that the Semantic View of theories provides a means of understanding how science describes reality, and I look at the way science has been used to distinguish the sexes to provide an illustration.     

When Extremists Win: Cultural Transmission Via Iterated Learning When Populations Are Heterogeneous

How does the process of information transmission affect the cultural or linguistic products that emerge? This question is often studied experimentally and computationally via iterated learning, a procedure in which participants learn from previous participants in a chain. Iterated learning is a powerful tool because, when all participants share the same priors, the stationary distributions of the iterated learning chains reveal those priors. In many situations, however, it is unreasonable to assume that all participants share the same prior beliefs. We present four simulation studies and one experiment demonstrating that when the population of learners is heterogeneous, the behavior of an iterated learning chain can be unpredictable and is often systematically distorted by the learners with the most extreme biases. This results in group‐level outcomes that reflect neither the behavior of any individuals within the population nor the overall population average. We discuss implications for the use of iterated learning as a methodological tool as well as for the processes that might have shaped cultural and linguistic evolution in the real world.     

Safe Sex Education for Adolescent Daughters: vhaVenda Mothers Views

The study explored vhaVenda mothers' perceptions of imparting safe sex education to their adolescent daughters. Data was collected through six focus group discussions with each group consisting of six to eight mothers. The results indicated that mothers want their children to be knowledgeable about sexuality to avoid consequences associated with negative sexual behaviour. The mothers were of the vew that children ought to receive sexuality education from parents. Nonethless, relatively few parents appear to be eager to discuss sexuality in great depth.     

Therapeutic Misconceptions: When the Voices of Caring and Research Are Misconstrued as the Voice of Curing

Research on doctor-patient communication has characterized such interactions as being asymmetrical. The present article tries to shift emphasis away from the different orientations individuals bring to the communicative setting and attempts to highlight the different orientations ("voices") within a given individual. We draw on an in-depth analysis of discourse between a 2 l-year-old man who can be ascribed the roles of both patient and potential research subject and an interviewer who acts in both the role of medical staff and researcher. Focusing our analysis on a limited number of linguistic forms (pronouns and demonstratives), it is argued that the use of the same form for different referents signals a conflation of two voices—the voice of health care ("caring") and the voice of "research." Furthermore, we argue that the voice of research is most likely to be interpreted by the patient/research subject within the framework of curing. As such, the present article promotes a shift in emphasis from different institutional—and as such often assumed to be preexisting—orientations between the communicating parties to differing orientations within the individual that cannot help but be misconstrued in terms of the curing voice. Our conclusion focuses on the ethical and discourse analytic implications of analyzing voices in a discussion.     

Gay Stereotypes: The Use of Sexual Orientation as a Cue for Gender-Related Attributes

This study investigated whether gay men and lesbians are assumed to have attributes stereotypically associated with the other gender. Participants were 110 male and female undergraduates from a private, Midwestern, U.S. university. Participants were randomly assigned to one of four conditions (i.e., gay male, lesbian, heterosexual female, heterosexual male) and rated their given target on possession of traditionally masculine and feminine occupational interests, activities, and traits. Results revealed that, despite some changes in the status of gay men and lesbians in society, stereotypes regarding sexual orientation were similar to those seen in studies conducted 20 years ago. Specifically, gay males were viewed as less masculine/more feminine than heterosexual males, and lesbians were viewed as more masculine/less feminine than heterosexual females.     

Psychometric Approaches Help Resolve Competing Cognitive Models: When Less Is More Than It Seems

Simple arithmetic word problems are often featured in elementary school education. One type of problem, "compare with unknown reference set," ranks among the most difficult to solve. Differences in item difficulty for compare problems with unknown reference set are observed depending on the direction of the relational statement (more than vs. less than). Various cognitive models have been proposed to account for these differences. We employed item response theory (IRT) to compare competing cognitive models of student performance. The responses of 100 second-grade students to a series of compare problems with unknown reference set, along with other measures of individual differences, were fit to IRT models. Results indicated that the construction integration model (Kintsch, 1988, 1998) provided the best fit to the data. We discuss the potential contribution of psychometric approaches to the study of thinking.     

When Words Are No Longer Necessary: The Gift of Ritual

SUMMARY

This study is an exploration of non-verbal forms of communication which have become ritualised, particularly m the care of people with dementia. Rituals, which are culturally determined, may be inclusive or exclusive; they may lose their meaning or send out mixed messages, but m general they uphold the structure of society. There is a strong link between religion and ritual and for people with dementia, ritual may be extremely important m maintaining their sense of belonging within the community of faith. It looks at some of the issues to be addressed when worshipping with people with dementia.     

Waiting When Both Certainty and Magnitude Are Increasing: Certainty Overshadows Magnitude

In everyday decision making, people often face decisions with outcomes that differ on multiple dimensions. The trade‐off in preferences between magnitude, temporal proximity, and probability of an outcome is a fundamental concern in the decision‐making literature. Yet, their joint effects on behavior in an experience‐based decision‐making task are understudied. Two experiments examined the relative influences of the magnitude and probability of an outcome when both were increasing over a 10‐second delay. A first‐person shooter video game was adapted for this purpose. Experiment 1 showed that participants waited longer to ensure a higher probability of the outcome than to ensure a greater magnitude when experienced separately and together. Experiment 2 provided a precise method of comparing their relative control on waiting by having each increase at different rates. Both experiments revealed a stronger influence of increasing probability than increasing magnitude. The results were more consistent with hyperbolic discounting of probability than with cumulative prospect theory's decision weight function. Copyright © 2014 John Wiley & Sons, Ltd.     

Magical Spaces: Sex as Art

Abstract

For the last 40 years I am trying to make Magic. First as a dancer and choreographer, creating performances and dance pieces, then using the skills I acquired in the theater and applying them to sex-positive spaces. What I describe here is not an academic thesis or a philosophical text. All the knowledge about Making Magic that I propose is derived from practical experience. It is a method developed in 40+ years working with and observing the body, while choreographing dance, group processes, and social events.     

When Empathy Matters: The Role of Sex and Empathy in Close Friendships

Based on prior theory and research (Ciarrochi & Heaven, 2009; Eagly & Wood, 1999), we hypothesized that the link between empathy and friendship would be moderated by sex: Girls will nominate empathic boys as friends, whereas boys will not tend to nominate empathic girls. We collected measures of empathy, friendship social support, and close friendship nominations in grade 10 across 1,970 students in 16 schools (M_age = 15.70, SD = .44; males = 993, females = 977). Multilevel models revealed that boys high in cognitive empathy attracted an average of 1.8 more girl friendship nominations than did their low empathy counterparts, whereas empathic girls did not attract a greater number of opposite‐sex friends. In addition, the more friendship nominations a boy received from either boys or girls, the more they felt supported by their friends; the number of friendship nominations received by girls, in contrast, had no effect on their felt support by friends. Regardless of the quantity of friendship nominations, empathy was linked to more supportive friendships for both males and females. These results inform a contextual understanding of the role of empathy in selecting and maintaining friendships.     

Child/Adolescent Abuse and Suicidal Behavior: Are They Sex Related?

The association between childhood and adolescent abuse and suicidal behavior, and the possible contribution of abuse to sex differences in non lethal suicidal behavior, was investigated. Data were extracted from the Israel‐based component of the WHO World Mental Health Survey (Kessler & Utsun, 2008a). Increased risk for ideation, plan, and suicidal attempt were associated with childhood abuse, and increased risk for attempt was associated also with abuse at adolescence. No associations with sex or sex by abuse interactions were observed. The higher frequency of childhood abuse among women could account in part for their higher rates of suicidal attempts as compared to men.     

When Sex Is on the Air: Impression Formation After Exposure to Sexual Music

The present study examines how young men and women, when primed with sexual cues in entertainment media, incorporate these cues into their first impressions of an unfamiliar target. Respondents (n = 188) were exposed to popular music either with or without sexual lyrics. Respondents in the sexual music condition recognized the sexual conveyance of that music. Respondents in the other condition rated the sexuality in their music as low. After exposure, respondents evaluated unknown targets—job applicants represented by their resumés. Sexual conveyance elevated ratings of sexual qualities attributed to the targets, suggesting sexual objectification of the targets. Sexual quality ratings then predicted evaluations of the targets’ merit, including knowledge and integrity. Although the association between sexual quality and overall merit ratings were positive for both men and women, men exhibited a significantly stronger association than women did. Findings support a postconscious automatic processing interpretation of media priming effects and corroborate prior observations that sexual media primes yield sexualized evaluations. Findings also suggest a need to measure initial affective responses to media primes, as different sexual depictions might trigger sexual thoughts with either a positive or negative connotation.     

My Friends Are My Estate: Friendship Experiences Mediate the Relationship Between Perceived Responses to Capitalization Attempts and Happiness

Emerging adults share the positive events in their lives with their friends, a process that is related to higher levels of happiness when they perceive their friends’ responses as more positive and less negative. What might explain this association? The four studies (N = 2997) in this research tested the proposal that positive friendship experiences mediate the relationship between perceived responses to capitalization attempts (PRCA) and happiness. Study 1 showed that same-sex friendship quality mediated the relationship between PRCA and happiness. Study 2 supported the model for cross-sex friendships. Study 3 tested the generalizability of the model for the immediate social network of emerging adults and showed that the model was only applicable to best friendships. Study 4 documented that satisfaction of basic psychological needs in a same-sex friendship was another mediator of the PRCA-happiness link. Although the friendship experiences and PRCA scores of women were higher compared to men in every study, the associations of PRCA with friendship experiences and happiness were generally similar and the model was supported for both men and women. The implications of the findings were discussed and suggestions for future research were provided.
