Roundtable: what is temperament? Four approaches   总被引:4,自引:0,他引:4  
4 current approaches to understanding temperament are discussed in the roundtable. In an introductory overview, Goldsmith outlines some of the major convergences and divergences in the understanding of this concept. Theorists representing 4 positions--Goldsmith, Buss and Plomin, Rothbart, and Thomas and Chess--outline their views by responding to each of 6 questions: How do you define temperament and explain the boundaries of the concept? What are the elements of temperatment? How does the construct of temperament permit you to approach issues or organize data in ways that are possible only if this construct is invoked? How does temperament develop? To what extent do you consider temperament to be a personological versus a relational or an interactional construct? and How does your approach deal with issues of temperamental "difficulty"? In 2 commentaries on the theorists' answers, Hinde highlights differences among their positions and indicates issues that current theories of temperament must take into consideration, and McCall draws on common aspects to propose a synthesizing definition that draws on all 4 approaches.  相似文献

School psychologists and administrators are often asked to respond to student violence and disorder based on incomplete or inaccurate information about the nature and scope of these problems in their schools. Records of disciplinary actions and incidents may reflect only the tip of the proverbial iceberg. In national surveys, school administrators report rates of violence and disorder that are only a small fraction of the rates reported by students in national self‐report surveys. Student self‐report surveys on school violence and disorder may offer school officials a means of more accurately appraising the prevention needs of their students. This article compares the methods and findings of three national surveys of students in an effort to understand what methodological characteristics have the most salient impact on their findings. The article examines measures of school‐related weapon carrying and fear from all three national surveys contrasting their modes of administration and question phrasing. Estimates from even the most expertly designed and administered survey will include some error. However, the stability and comparability of the national surveys across time and across surveys suggest that student self‐report surveys are valuable tools for school‐level needs assessment. © 2001 John Wiley & Sons, Inc.  相似文献

This paper is about how to teach a foreign language at a distance, i.e. how to support the learning of a foreign language by students who are not taught by teachers face‐to‐face. Much experience about this has been collected by correspondence schools and similar organisations. Among the public bodies of importance here should be mentioned the state‐owned and state‐run French Centre National d'Enseignement par Correspondence and Athabasca University in Alberta, Canada. Little seems to have been published about teaching and learning foreign languages at a distance, although Rousseau 1977 and contributions to ICDE and EHSC conferences (in 1982 and 1979) have surveyed essential problem areas. Experiences of teaching English as a foreign language provide the basis from which many considerations are examined.  相似文献

The theoretical basis, the development and the use of an inventory designed to measure styles of learning and motivation are described. On the basis of previous research, items within the inventory were located on 20 sub-scales. The ten motivation sub-scales were derived from a theory of school motivation which was based on extensive interview and inventory work carried out in Hungary with children, their parents and teachers. The ten scales describing styles of learning were derived from concepts describing learning approaches and styles which emerged from interviews and experimental research with students in British and Swedish higher education. Versions were prepared in both English and Hungarian and given to samples of 614 British and 579 Hungarian pupils aged between 13 and 17 years. A remarkably similar factor structure was obtained in each sample. An analysis of mean scores indicated distinctive differences both between boys and girls, and between British and Hungarian pupils. Cluster analysis was used to investigate the possible existence of styles which combined both approaches to learning and aspects of school motivation. The potentiality of the inventory for use in conjunction with study skills courses is discussed.  相似文献

About a third of play groups observed in a part‐time and full‐time early childhood centre were of mixed gender and two‐thirds were same gender. Mixed gender groups were larger than same gender groups and kindergarten (part‐time) groups were larger than childcare (full‐time) centre groups. In the kindergarten, outdoor play was much more common and there was a significant difference in boys preferring to play outdoors, followed by mixed groups and then girls. In both centres boisterous play was more likely in boys’ groups than girls’ groups, with mixed groups more similar to boys’ groups in the predominance of boisterous play. Boys’ groups in both centres exclusively used male themes for pretend play, while girls mostly used female themes and an occasional male theme. Mixed gender groups used male themes almost as much as male groups, but rarely or never used female themes. There was more physical conflict and rejection in mixed groups, than boys’ groups and none in girls’ groups in the kindergarten. There was more adult involvement in girls’ groups than in boys'groups in both centres, but mixed groups had an intermediate amount in the kindergarten and slightly more than girls in the childcare centre. Boys enjoyed noisy, rough and tumble play, competition for dominance, stereotyped male themes and sometimes actively rejected the presence of the researcher. Girls preferred quiet adult‐structured table activities and supportive conversations over activities with peers and adults. While there were examples of successful cross‐gender co‐operative play, there were also examples of the breakdown of reciprocity due to contrasting styles of play.  相似文献

The reliability and validity of a revised version of Finucci's (1982) Reading History Questionnaire was examined in two adult samples. One sample included 84 adults from an ongoing study of familial dyslexia, and a second sample was composed of parents of 107 children from a longitudinal study of reading development. Internal consistency was demonstrated by Cronbach's alphas of .94 and .92 in the two samples. Test-retest reliability was demonstrated by significant correlations (.87 and .84 in the two samples) over several years between an earlier and revised form of the questionnaire. Validity was demonstrated via (a) correlations between the questionnaire score and reading measures (rs = .57-.70), (b) the results of a discriminant function analysis that used questionnaire scores to predict reading disability diagnosis, and (c) the finding that the questionnaire had substantial incremental validity in predicting reading skill in a hierarchical regression analysis that first entered IQ and SES. These results indicated that the questionnaire is both reliable and valid.  相似文献

OBJECTIVE: The goal was to develop a retrospective inventory of parental threatening behavior to facilitate a better understanding of such behavior's role in the etiology of psychological distress. METHOD: Inventory items were developed based on theory and 135 students' responses to a question eliciting examples of threatening parental behavior. Following item development, two additional student samples (n = 200 and n = 603) completed batteries of self-report measures. Responses were used to eliminate unstable or redundant items from the inventory and to examine the inventory's psychometric properties. RESULTS: Factor analysis of the inventory revealed three factors, accounting for 66.2% of variance; this factor structure is compatible with theory, and consistent across maternal behavior scores, paternal behavior scores, and combined maternal and paternal scores. Cronbach's coefficient alphas indicated acceptable internal consistency; Pearson correlation coefficients indicated acceptable 4-week test-retest reliability. Moderate intercorrelations with two retrospective measures of childhood experiences suggested construct validity. Regression analyses demonstrated the ability of the inventory to predict both anxious and depressive symptomatology and lifetime symptoms of anxiety and depressive disorder. Normative data on combined parent scores, maternal scores, and paternal scores are also presented. CONCLUSIONS: Initial psychometric testing of the Parent Threat Inventory (PTI) suggests it is a reliable and valid tool for investigating the developmental antecedents of adult psychological distress. Further research should focus on addressing two limitations: (1) lack of normative and psychometric data on men and women suffering from clinical disorders, and (2) lack of validation by parental reporting.  相似文献
