Factors influencing the tendency to be aggressive were investigated in male house mice using a series of paired encounters. Body size, body lenght, body temperature, age, and anogenital distance were measured on all males. Paired encounters were conducted using a standard mouse cage as an arena. Across 64 males involved in 224 encounters, the tendency to be dominant and win encounters was significantly correlated only with anogenital distance (r = 0.383). These findings suggest that there are significant behavioral effects in male mice that could parallel the intrauterine position and related prental hormone effects that have been elucidated in female house mice and other rodents. © 1995 Wiley-Liss, Inc.  相似文献

The present study was undertaken to test the recently advanced hypothesis that highly religious people are more prone to obesity than is true for people in general. Based on a sample of over 6000 middle- to older-aged women, the study found essentially no support for the hypothesis. The only possible exception was in the case of members of certain denominations with historically high birth rates.  相似文献

These studies proposed that effective social accounts should contain external, unstable, specific, and uncontrollable attributions. In Study I, managers provided accounts for a negative event. The accounts contained highly unstable and specific attributions but, contrary to original predictions, they also contained highly internal and controllable attributions. In Study 2, managers rated the effectiveness of the account. Account effectiveness was positively related to unstable attributions, but was negatively related to external and uncontrollable attributions. These relationships were stronger (more negative) for accounts communicated downward than upward. These results indicate that blaming others or deflecting personal responsibility for negative events may be ineffective, especially when one is in a high‐status role.  相似文献

Type A behavior and optimism were examined as predictors of blood pressure and job performance in a hospital setting. Results indicate that the achievement striving dimension of Type A behavior was negatively related to blood pressure. The impatient/irritable dimension of Type A behavior was unrelated to either performance or blood pressure. The interaction of achievement striving Type A behavior and optimism was related to blood pressure and technical job performance. Specifically, achievement striving predicted blood pressure and technical performance when optimism was high but not when it was low. Implications for future research are discussed.  相似文献

A three-phased study was conducted in order to develop a standardized list of touch-related adjectives. The final list consisted of 306 words that were categorized in 440 instances according to the Lederman and Klatzky (1987, 1990) dimensions of haptic properties (some words were classified in more than one dimension). The Kučera and Francis (1967) frequency of occurrence in written English for all words in the final list was also determined. A correlation was found between frequency of occurrence on the list and Kučera and Francis frequency. An analysis of the word dimensions and future applications are discussed.  相似文献

Psycholexical studies of personality structure in several languages have recovered, in addition to variants of the Big Five factors, a sixth factor that has been given names suggesting honesty, such as ‘Integrity’, ‘Trustworthiness’, ‘Truthfulness’, and ‘Values’. Using a sample of Korean respondents (N = 610), we correlated lexical markers of the Big Five and the Honesty factor with several questionnaire variables that are relevant to the exploitation of others, including Machiavellianism, Psychopathy, and Social Adroitness. Results indicated that those measures were much more strongly related to the Honesty factor than to any of the Big Five. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

In an era of seemingly intense populist politics, a variety of issues of intergroup prejudice, discrimination, and conflict have moved center stage in much of the industrialized world. Among these is “political correctness” and, in particular, what constitutes a legitimate discourse of political and social conflict and opposition. Yet the meaning of legitimate discourse is being turned on its head as some disparaged groups seek to reclaim, or reappropriate, slurs directed against them. Using as a context a U.S. Supreme Court case about whether “The Slants”—a band named after a traditional slur against Asians—can trademark its name, we test several hypotheses about reappropriation processes based on a nationally representative sample with an oversample of East Asian Americans and several survey experiments. We find that motives attributions influence how people understand and evaluate potentially disparaging words. In particular, when reappropriation motives are perceived, insulting words are judged to be less insulting. In this sense, uncivil discourse can to some degree be tamed.  相似文献

Legacy for Children™ (Legacy) is an evidence-based program focused on promoting sensitive, responsive parenting for socioeconomically disadvantaged families. Legacy has recently been culturally and linguistically adapted for Spanish-monolingual Latino families and is being piloted in partnership with an early childhood education program. We conducted a mixed methods study to identify barriers and facilitators to engagement, using program monitoring data sources from both participant and group leader perspectives. We conducted qualitative analyses of open-ended data to identify distinct barriers (e.g., employment challenges, health-related challenges and appointments) and facilitators (e.g., other mothers in group, interest in program topics) to engagement that emerged across English and Spanish language curriculum versions; curriculum-specific barriers and facilitators were also documented. We interpret these findings in light of quantitative data on measures of engagement, showing that participants in the Spanish curriculum evidenced comparable levels of parent–group leader relationship quality relative to the English group, and higher levels of parent's group support/connectedness and overall satisfaction. These results offer promising considerations for optimizing families’ engagement in parenting programs in the context of early care and education settings.  相似文献

The purpose of this study is to test key social capital indicators in a disaster context by considering the bonding and bridging types of social capital. Using the East Asian Social Survey, this study chooses three behavioural/cognitive elements of social capital—social trust, voluntary association membership, and personal networks—and divides them into bonding and bridging social capital, in‐group and out‐group trust, homogeneous and heterogeneous membership, and strong and weak ties to test their effects on self‐evaluated community resilience to natural hazards. The results showed that social trust and personal networks had strong positive effects, but the effect of voluntary association membership was positive in societies with high rates of membership (Japan and South Korea) and negative in a society with a low rate of membership (Taiwan). Furthermore, while bonding social capital generally showed a stronger effect than bridging social capital in East Asia, a society with more frequent and intense disasters (Japan) showed a strong effect of heterogenous membership on self‐evaluated community resilience. This study connects two aspects of social capital studies—the elements and the types of social capital—and the findings imply that the relationship between social capital and community resilience may have some mediator variables.  相似文献
