The simplest interlimb multifrequency coordination of 1:2 can be performed at different speeds and in at least two different styles or modes. The effects of speed and mode (in-phase or antiphase) were evaluated in a bimanual 1:2 rhythmic task in which participants (N = 8) oscillated hand-held pendulums with identical or different uncoupled frequencies. A motion equation in relative phase that captures the asymmetries of components and task predicted the 1:2 coordination equilibria resulting from temporal scaling. According to the experimental results, both coordination modes proved to be equally stable. More detailed analyses of individual trials showed signs that the more fundamental 1:1 coordination intruded into the 1:2 coordination. 相似文献

Fear of death and institutional separation of persons of different age groups are major contributors to ageism. Drawing on
research in social psychology, this article introduces two remedies that can reduce stereotypes toward older adults: The first
remedy is intergenerational connections with the intergroup contact hypothesis as its theoretical underpinnings. The second
remedy is use of narrative in age-heterogeneous groups. Since religious communities are among the few places in society where
persons of all stages of life meet, they can, when intentionally structured, be settings with promise for intergenerational
connections and play a role in counteracting ageism. 相似文献

In educational AIDS campaigns, initiators often use advertisements to warn about the threat of AIDS. The present Internet study (N = 283) tested the assumption of an inverted U-shaped relationship between the number of educational AIDS advertisements in a magazine and the perceived threat of AIDS among different groups (i.e., homosexual men and heterosexual men and women). This expectation was primarily based on signaling theory, which assumes that recipients use repetition frequency as a cue for judgments about the message. Results provided support for the expected inverted U-curve. 相似文献

Prenatal testing for Down Syndrome is a topic covered in every genetic counselor’s training as it constitutes the main workload
of genetic counselors in prenatal settings. Most Western countries nowadays offer some type of testing for Down Syndrome.
However, practices vary according to country with regards to what tests are offered, insurance coverage and the legal situation
concerning the option of terminating an affected pregnancy. In view of the growing interest in international genetic counseling
issues, this article aims to compare prenatal testing practices in two English-speaking countries: the United Kingdom and
the United States of America. A case will be presented to highlight some of the differences in practice. The topic underlines
important implications for genetic counseling practice, such as patients’ understanding of testing practices, risk perception,
counseling provision and impact of prenatal testing results. 相似文献

Information seeking of high- and low-anxiety subjects after receiving positive and negative self-relevant feedback 总被引:1,自引:0,他引:1
The present paper reports an experiment in which subjects received fictitious intelligence test feedback that was either negatively or positively discrepant with their self-evaluation. They were then given an opportunity to choose among several articles containing information that either derogated intelligence tests (test-disparaging information) or argued for their validity (test-supporting information). The main finding of this study consists of an interaction between the personality factor anxiety and the feedback variable: High-anxiety subjects prefer test-disparaging information significantly more in the negative feedback condition than in the positive feedback condition, whereas low-anxiety subjects show no difference in preference for test-related information as a function of the feedback condition. These results are in line with past theoretical reasoning and experimental findings showing that high-anxiety subjects feel more threatened by negative self-relevant feedback than do low-anxiety subjects. 相似文献

Television as one factor in the “cycle of role division” (Eagly 1987; Shields 2002) can aid to perpetuate traditional role attitudes as well as set new norms. The aim of the study is to examine gender differences in facial expression of emotion on TV as well as changes of these differences over time. A content analysis of 12 episodes of a prominent German crime series from two time samples (1979–1981 / 2005) was done by employing the Emotional Facial Action Coding System (EmFACS, Friesen and Ekman 1983). Results show that there are gender differences in stereotypically male emotions: Male actors express these emotions significantly more frequently than female actors, while the latter show more “social smiles”. These differences are reduced over time. 相似文献
