The authors examined differences in drinking behaviors and related risk factors across campus housing at a women's liberal arts college. Participants (N = 362) living in residence-style housing or house-style residences completed self-report questionnaires. Results showed that students in residence hall-style houses reported higher levels of hazardous alcohol use and perceived that their college, housemates or roommates, and close peers are more permissive of alcohol use than did students living in house-style residences. Findings highlight the role of the environmental structure of a college campus on students' perceptions of alcohol use and their drinking behaviors. The authors discuss implications for college housing and programming.  相似文献

A frustration theory of pursuit rotor performance and reminiscence has previously been presented (Costello, 1967; Costello & Discipio, 1967). The theory was reformulated in terms of arousal theory and the following hypotheses were tested: (1) an inverted “U” relationship exists between level of arousal and performance level; (2) reminiscence results when S during the rest period moves closer to his optimum level of arousal; (3) massed practice produces a higher level of arousal than spaced practice; (4) experimental conditions producing a high drive state will also increase his arousal level. Findings in line with these hypotheses were found for EMG measures but not for GSR and pulse rate. In view of what appears to be the task-specific nature of the physiological results it was concluded that there was no particular advantage in reformulating the frustration theory in terms of arousal theory.  相似文献

Previous research on the ideational process indicates that original ideas increase in frequency as an examinee works through an open-ended task. In the present investigation, ideational flexibility was evaluated to determine if ideas also become more varied and diverse. Additionally, the relationship of intelligence (IQ) with order effects of both originality and flexibility was investigated. Tests of verbal and figural divergent thinking were administered to 80 intermediate school children. The midpoint of each individual's ideational set was found, and the flexibility and originality scores of each half of the set were compared. Results indicated that flexibility and originality scores were higher in the second half than the first half of the ideational set, but there were significant differences between high- and low-originality subjects and differences between the verbal and the figural tests. The order effect was unrelated to the IQ scores of the subjects. Suggestions are made to integrate ideational flexibility into existing theories of divergent ideation.  相似文献

Abstract

This study tested a developmental model of cognitive performance in adolescence and explored potential mechanisms explaining the relations of early maternal stimulation and children’s anxious behaviors with adolescents’ cognitive performance. We utilized the NICHD SECCYD dataset (n?=?1,112). Measures included questionnaires, coded observations, and self-report measures from infancy to adolescence. Results revealed that children who experienced greater early maternal stimulation and less anxious behaviors had better cognitive performance at age 15. Children’s English self-efficacy, the quality of child–teacher relationships, and children’s behavioral classroom engagement in middle childhood mediated the relation between early maternal stimulation and adolescent cognitive performance. Identifying pathways from earlier maternal and children’s characteristics to children’s later cognitive performance is an important step toward further understanding why early precursors have a long lasting impact on cognitive performance, and has implications for educational settings.  相似文献

Research in the United States has found a strong and consistent relationship between teacher behavior and learning. Data collected from American college students indicate that perceptions of teacher nonverbal immediacy (NVI) are associated with students' feelings toward learning and perceptions of cognitive learning. The purposes of this study were to accomplish the following: (1) develop standardized Japanese versions of the instruments used to measure teacher nonverbal immediacy, student motivation, and perceived cognitive learning (how much students think they have learned); and (2) assess the relationship between NVI, student motivation, and perceptions of cognitive learning among Japanese college students. Results note that Japanese students report (1) a positive relationship between reported levels of teacher NVI and student motivation; (2) a negative relationship between reported levels of teacher NVI and perceived learning loss; and (3) a negative relationship between student motivation (SM) and perceived learning loss (how much students think they did not learn with their teacher compared to an ideal teacher). Further, cross-cultural comparisons between Japanese and American students were conducted. Results from the cross-cultural comparison suggest that the relationships between reported teacher nonverbal immediacy, student motivation, and learning loss among Japanese college students are similar to those found among American college students, but the dimensional structure of the questionnaires was different.  相似文献

Many have claimed that education of the ethical issues raised by biotechnology is essential in universities, but there is little knowledge of its effectiveness. The focus of this paper is to investigate how university students assess the information given in class to make their own value judgments and decisions relating to issues of agricultural biotechnology, especially over genetically modified organisms (GMOs). Analysis of homework reports related with agricultural biotechnology after identification of key concepts and ideas in each student report is presented. The ideas were sorted into different categories. The ideas were compared with those in the reading materials using the same categories. These categories included: concern about affects on humans, affects on the environment, developing countries and starvation, trust in industry, responsibility of scientists, risk perception, media influence, need for (international) organizations or third parties, and information dissemination. What was consistent through the different years was that more than half of the students took a “neutral” position. A report was scored as “neutral” when the report included both the positive and negative side of an issue, or when the student could not make a definite decision about the use of GMOs and GM food. While it may be more difficult to defend a strong “for” or “against” position, some students used logical arguments successfully in doing so. Sample comments are presented to depict how Japanese students see agricultural technology, and how they value its application, with comparisons to the general social attitudes towards biotechnology.  相似文献

Student Evaluations and Moral Hazard   总被引:1,自引:0,他引:1  
Most universities solicit feedback from students at the end of a course in order to assess student perceptions of the course. This feedback is used for various objectives, including for evaluating teaching by academic administrators. One would therefore expect faculty to rationally take this into account while formulating their teaching strategy. In certain cases, such strategic considerations can give rise to moral hazard. I have modelled the situation using the well-known Prisoners Dilemma game and found that in equilibrium, the teaching style will be examination-centric, while considerations of societal good would demand that the teaching style be knowledge-centric. I also discuss the policy implications for this finding.  相似文献

初一新生学习适应过程研究   总被引:1,自引:0,他引:1  
为探讨初一新生学习适应规律和特点,采用“初中生学习适应问卷”,追踪调查了450名初一新生。结果表明: (1)初一新生的学习适应性总体发展呈“V”型趋势,即入学后第一个月没有明显的不适应感,入学后两个月左右出现明显的不适应感,四个半月后又有所好转; (2)新生学习适应性在性别、生源地区、学校类型上存在显著差异。建议学校和教师在新生入学后的第二、三个月加强学习适应指导。  相似文献

Little has been written about how genetic counseling supervisors can help students develop psychosocial skills in their clinical rotations. The authors describe several approaches supervisors can use, ranging from preventive measures (e.g., normalizing anxiety), to skill-enhancing interventions (e.g., modeling and thinking aloud), to more direct approaches (e.g., immediacy, confrontation) that may be necessary for students who are reluctant, or even resistant, to using psychosocial skills with their clients.  相似文献

SLANG—Sensitive Language and the New Genetics—is a concept that arose out of informal discussions between a number of interested parties, both consumers and professionals, who were becoming increasingly uneasy with some of the language commonly used in medical genetics. Some language choices were felt by the authors to be inappropriate for a variety of reasons. Poor language choice may impede an individual's understanding of a genetic condition or important medical information and the chosen words themselves may simply be perceived as discriminatory and even offensive. SLANG is an important concept to explore partly because literature in this area confirms that language choices in medical settings can be of great significance to both patients and families. Studies have shown how language choices impact on professional practice by, as one example, changing the intended meaning of medical information and affecting individual perception of risk and choice which, in turn, may affect individual or familial well-being. In addition language choice has the power to affect how individuals perceive themselves and are viewed by others. This paper presents the results from our pilot study and discusses the implications for health professionals with particular reference to medical genetics settings.  相似文献
