Mechanical knowledge does matter to tool use even when assessed with a non-production task: Evidence from left brain-damaged patients

In the literature on apraxia of tool use, it is now accepted that using familiar tools requires semantic and mechanical knowledge. However, mechanical knowledge is nearly always assessed with production tasks, so one may assume that mechanical knowledge and familiar tool use are associated only because of their common motor mechanisms. This notion may be challenged by demonstrating that familiar tool use depends on an alternative tool selection task assessing mechanical knowledge, where alternative uses of tools are assumed according to their physical properties but where actual use of tools is not needed. We tested 21 left brain-damaged patients and 21 matched controls with familiar tool use tasks (pantomime and single tool use), semantic tasks and an alternative tool selection task. The alternative tool selection task accounted for a large amount of variance in the single tool use task and was the best predictor among all the semantic tasks. Concerning the pantomime of tool use task, group and individual results suggested that the integrity of the semantic system and preserved mechanical knowledge are neither necessary nor sufficient to produce pantomimes. These results corroborate the idea that mechanical knowledge is essential when we use tools, even when tasks assessing mechanical knowledge do not require the production of any motor action. Our results also confirm the value of pantomime of tool use, which can be considered as a complex activity involving several cognitive abilities (e.g., communicative skills) rather than the activation of gesture engrams.

电视广告中性别角色定型研究述评

文章首先介绍了性别角色定型的相关概念和广告中性别角色定型研究的理论基础,然后从内容分析和受众反应两个角度回顾并总结了有关电视广告中性别角色定型的研究。内容分析的结果表明：虽然经过了20多年的女权运动,电视广告中的性别角色定型并没有减弱;电视广告中的性别角色定型具有国际普遍性。受众反应的结果表明：受众对电视广告中的性别角色定型的反应是一个复杂的过程,会受到多种因素,比如性别、年龄、受教育程度和女性主义意识等的影响     

对广告信息加工的性别差异

研究者运用加工分离程序(PDP),探讨了在不同性别的广告代言人条件下,不同性别的目标受众对其所代言品牌在控制性加工和自动化加工水平上的差异。结果发现：（1）在男性代言人条件下,男性受众对其所代言品牌的自动化加工水平明显高于女性被试,两者控制性加工水平差异不显著;（2）在女性代言人条件下,女性受众对其所代言的品牌的自动化加工水平明显高于男性被试,两者的控制性加工水平差异不显著。实验结果对广告的设计与制作有着借鉴意义。     

What Difference Can a Year Make? Changes in Functional and Aesthetic Body Satisfaction Among Male and Female Adolescents Over a Year

The current study explored changes in functional and aesthetic body satisfaction among Australian adolescents over a year. Data were collected from 1,342 Australian adolescents (567 males, 775 females) across two grade cohorts (Grades 8 and 10) at Wave 1 (W1; mean age = 13.7) and again 12 months later at Wave 2 (W2). Participants' functional and aesthetic body satisfaction, body mass index (BMI), and relative pubertal timing were measured. Body image change was explored across both grade cohort and gender, controlling for differences in BMI change and relative pubertal timing. Females reported lower overall (functional and aesthetic) body satisfaction than males. Participants reported higher functional and aesthetic body satisfaction at W1 than W2. Although both males and females reported a significant decrease in body satisfaction over the 12‐month period, this decrease was stronger among female participants. ^?Cohort differences were also found with older adolescents reporting lower functional body satisfaction.     

Warrior Chicks: Youthful Aging in a Postfeminist Prosperity Discourse

In a youth‐oriented evangelical congregation where being perceived as “old” might marginalize member involvement and participation, a Hollywood, California congregation's women's ministry, God Chicks, presents aging women as possessing “godly wisdom,” endowing older women with spiritually charged energy, authority, and responsibility for training younger women to live “godly” lives. Ethnographic research and in depth media analysis of the God Chicks ministry reveals a particularly energizing evangelical postfeminist orientation that applies prosperity theology to contemporary challenges of changing women's roles. Specifically, the God Chicks ministry provides “women over forty” with consumer and caretaking strategies for maintaining youthful selves and motivating younger women. A “God Chick” emerges as a compelling, youthful gendered religious identity that expects congregationally committed women to be strong, healthy, and active warriors who fight multiple relational and global humanitarian battles. Overall, this study demonstrates the construction of an innovative postfeminist evangelical identity through the tactical, opportunistic use of theological doctrine by ministry leaders within a particularistic geographic location.     

The Effects of Gender Role Orientation on Team Schema: A Multivariate Analysis of Indicators in a U.S. Federal Health Care Organization

Abstract

In this empirical study of 649 employees at a federally supported health care facility in the United States, the authors investigated the effects of individual gender role orientation on team schema. The results indicated (a) that nontraditional male and female employees perceived the greatest amount of group cohesion in their team schemas and (b) that both traditional and nontraditional male employees perceived greater problem-solving potential in their team schemas. Meaningful implications for team composition are discussed.     

Social Support and the Ability to Adapt to Life Among Brazilian Street Children and Non-Street Children

Abstract

Value priorities were analyzed as they relate to nationality (American vs. British) and gender in a study involving 207 university students from the 2 countries. Participants responded anonymously to S. H. Schwartz's Value Survey (1992, 1994), consisting of various individualistic and collectivistic values. American students assigned greater importance to the individualistic values of achievement, hedonism, self-direction, and stimulation than British students did; students from the 2 countries assigned equal importance to the power value type. Compared with men, women from both countries assigned greater value priorities to the collectivistic values of benevolence, universalism, security, and subordination of self to others. Women and men, however, did not differ on the individualistic values, and, in fact, women placed greater importance on achievement than men did. The results for the individualistic values are discussed primarily within the context of major changes in the career and work opportunities afforded women by society in the past 30 years.     

Racial Bias in Decisions Made by Mock Jurors Evaluating a Case of Sexual Harassment

Abstract

White (N = 161) and Black (N = 152) college students served as mock jurors in a simulated civil case in which a female plaintiff accused a male defendant of sexual harassment. The authors experimentally manipulated the race (Black or White) of the litigants and asked the mock jurors to decide whether the defendant was guilty; to rate the certainty of their belief in the defendant's guilt; and, when they judged the defendant guilty, to recommend an award to the plaintiff. Mock jurors of both races tended to favor litigants of their own race and their own gender. Racial bias was highest among White male jurors and lowest among White female jurors.     

Stressed and Helping: The Relations Among Acculturative Stress,Gender, and Prosocial Tendencies in Mexican Americans

ABSTRACT

Available evidence suggests that stress is not necessarily linked to negative outcomes and, in fact, may lead to increases in sympathy and helping. In this study, we examined whether acculturative stress was associated with prosocial tendencies in a sample of 148 Mexican American college students (M age = 23.05 years; 99 women). Participants completed measures of acculturative stress, sympathy, and prosocial tendencies. The relations between acculturative stress and prosocial tendencies were generally positive but varied by the type of helping and gender. Higher levels of acculturative stress were linked to greater emotional, dire, compliant, and anonymous prosocial tendencies, as well as with fewer costly (altruistic) prosocial tendencies. Sympathy mediated the relations between acculturative stress and prosocial tendencies for men only.
