Growth in Externalizing and Internalizing Problems in Childhood: A Prospective Study of Psychopathology Across Three Generations     

Deborah M. Capaldi  Katherine C. Pears  David C. R. Kerr  Lee D. Owen  Hyoun K. Kim 《Child development》2012,83(6):1945-1959

Three generations of participants were assessed over approximately 27 years, and intergenerational prediction models of growth in the third generation’s (G3) externalizing and internalizing problems across ages 3–9 years were examined. The sample included 103 fathers and mothers (G2), at least 1 parent (G1) for all of the G2 fathers (99 mothers, 72 fathers), and 185 G3 offspring (83 boys, 102 girls) of G2, with prospective data available on the G2 fathers beginning at age 9 years. Behavior of the G2 mother, along with father contact and mother age at birth were included in the models. Intergenerational associations in psychopathology were modest, and much of the transmission occurred via contextual risk within the family of procreation.  相似文献   

Buddy up: the Köhler effect applied to health games     

Feltz DL  Kerr NL  Irwin BC 《运动与训练心理学杂志》2011,33(4):506-526

The present investigation examined the K?hler motivation gain effect in a health game using an absent partner, presented virtually. The K?hler effect occurs when an inferior team member performs a difficult task better in a team or coaction situation than one would expect from knowledge of his or her individual performance. The effect has been strongest in conjunctive task conditions in which the group's potential productivity is equal to the productivity of its least capable member. Participants were randomly assigned to one of four conditions (individual control, coaction, additive, and conjunctive) in a 4 (conditions) ? 2 (gender) factorial design and performed a series of isometric plank exercises within an exercise game. They performed the first series of five exercises alone holding each position for as long as they could, and, after a rest period, those in the partner conditions were told they would do remaining trials with a same-sex virtual partner whom they could observe during their performance. The partner's performance was manipulated to be always superior to the participant's. Results showed that task persistence was significantly greater in all experimental conditions than in the individual control condition. The conjunctive condition was no more motivating than either the additive or coactive conditions. Results suggest that working out with virtually present, superior partners can improve persistence motivation on exercise game tasks.  相似文献

Children's perceptions of primary science assessment in England and Wales     

Colette Murphy  Laura Lundy  Lesley Emerson  Karen Kerr 《British Educational Research Journal》2013,39(3):585-606

This study builds on and contributes to work on assessment of children in primary school, particularly in science. Previous research has examined primary science assessment from different standpoints, but no studies have specifically addressed children's perspectives. This article provides additional insight into issues surrounding children's assessment in primary school and how the assessment of science might develop in England after the science SATs (Standard Assessment Tests) were abolished in 2009. Some research suggests that primary science assessment via SATs is a major reason for the observed decline in children's engagement with science in upper primary and lower secondary school. The analytic focus on engaging children as coresearchers to assist in the process of gathering informed views and interpreting findings from a large sample of children's views enables another contribution. The study, based on a survey of 1000 children in primary and secondary schools in England and Wales, reveals that despite being assessed under two different regimes (high‐stakes national tests in England and moderated teacher assessment in Wales), children's views of science assessment are remarkably consistent. Most appreciate the usefulness of science assessment and value frequent, non‐SATs testing for monitoring/improving science progress. There was a largely negative impact, however, of science assessment on children's well‐being, particularly due to stress. The paper demonstrates that children provide an important perspective on assessment and that including their views can improve policy‐making in relation to primary science assessment.  相似文献   

Somatotype and size of elite female basketball players     

JEL Carter  TR Ackland  DA Kerr  AB Stapff 《Journal of sports sciences》2013,31(10):1057-1063

The aim of this study was to compare the somatotype and size of elite female basketball players in terms of playing position and team performance. Anthropometry and somatotype data were collected on 168 players from 14 countries before the Women's World Basketball Championship, Australia, 1994. There were 64 guards (mean?±?s: age 25.4?±?3.3 years, height 1.72?±?0.06?m, mass 66.1?±?6.2?kg, somatotype?=?2.9?–?3.9?–?2.6), 57 forwards (age 25.2?±?3.8 years, height 1.81?±?0.06?m, mass 73.3?±?5.9?kg, somatotype?=?2.8?–?3.5?–?3.2) and 47 centres (age 24.1?±?3.1 years, height 1.90?±?0.06?m, mass 82.6?±?8.2?kg, somatotype?=?3.2?–?3.1?–?3.4). Mean somatotypes by position were significantly different (F?=?7.73, P?<?0.01). Guards had greater mesomorphy than centres and less ectomorphy than forwards and centres. When discriminant function analysis was applied to endomorphy, mesomorphy, ectomorphy, age, height and mass, only height, mass and ectomorphy entered (Wilks' λ?=?0.351, F?=?31.40, P?<?0.000), 70% of the variance was accounted for, and 72% of players were correctly classified. In the four top versus four bottom teams, guards were taller and more ectomorphic, forwards were taller, with lower mesomorphy and higher ectomorphy, and centres did not differ. Thus there are some differences in somatotypes by position and team placing, but the combination of height, mass and ectomorphy provide the best differentiation by position.  相似文献   

Examining the impact of the Respect in Sport Parent Program on the psychosocial experiences of minor hockey athletes

ABSTRACT

Models of positive youth development suggest that athletes may be influenced by parent education programmes; however, there is little research examining the impact of such programmes on athlete outcomes. This study examined the impact of the Respect in Sport Parent Program on athlete outcomes among minor hockey players over three years. This study consisted of cross-sectional and longitudinal online surveys measuring athletes’ positive and negative developmental experiences, prosocial and antisocial behaviours, parental support and pressure, and sport enjoyment and commitment. Athletes completed at least one online survey during the study period (N = 366; 84.2% males; 14–19 years of age; M = 15.4 years), and 83 athletes completed multiple surveys for longitudinal analyses. Cross-sectional results comparing athletes in leagues adopting the programme at different time points indicated significant differences in prosocial behaviours towards teammates. Multilevel longitudinal analyses revealed improvements in athletes’ antisocial behaviours towards opponents, initiative, goal setting, and cognitive skills over time, regardless of whether they were in a league that implemented the programme. However, athletes in leagues that implemented the programme during the study reported greater improvements in antisocial behaviours towards opponents, and there were trends with respect to improved personal and social skills. These findings provide suggestions to improve the delivery and impact of parent education programmes in youth sport.  相似文献

Relationships between self-concept and directly observed behaviors in kindergarten children     

Phillip S. Strain  Mary Margaret Kerr  Vaughan Stagg  Donna A. Lenkner  Deborah L. Lambert  Sylvia R. Mendelsohn  Vany M. Franca 《Psychology in the schools》1983,20(4):498-505

Twenty kindergarten children who were nominated by teachers as not being socially and academically competent (low-rated) and 36 kindergarten children who were nominated by teachers as competent (high-rated) participated in this study. Self-concept and academic achievement data were gathered on each subject. In addition, all children were observed in class, with particular attention to compliance/non-compliance with adult requests, on-task/off-task behavior, and positive/negative social behaviors with peers. The results indicate that: (a) The factor structure of the self-concept instrument (Primary Self-concept Inventory) was replicated in both groups of children. (b) There were no significant differences in self-concept scores among high- vs. low-rated children. (c) There were profound differences in academic and social behaviors that were found to covary with positive self-evaluations within the two study groups. In general, high-rated children who felt best about themselves were higher achievers and more compliant than were their study group cohorts. Low-rated children who felt best about themselves were, on the contrary, more off-task, more negative in their peer contacts, and inferior academically to their study group cohorts.  相似文献   

Olympic lightweight and open-class rowers possess distinctive physical and proportionality characteristics     

Kerr DA  Ross WD  Norton K  Hume P  Kagawa M  Ackland TR 《Journal of sports sciences》2007,25(1):43-53

Rowers competing at the 2000 Olympic Games were measured for 38 anthropometric dimensions. The aim was to identify common physical characteristics that could provide a competitive advantage. The participants included 140 male open-class rowers, 69 female open-class rowers, 50 male lightweight rowers, and 14 female lightweight rowers. Body mass, stature, and sitting height were different (P < 0.01) between the open-class and lightweight rowers, as well as a comparison group of healthy young adults ("non-rowers", 42 males, 71 females), for both sexes. After scaling for stature, the open-class rowers remained proportionally heavier than the non-rowers, with greater proportional chest, waist, and thigh dimensions (P < 0.01). Rowers across all categories possessed a proportionally smaller hip girth than the non-rowers (P < 0.01), which suggested the equipment places some constraints on this dimension. Top-ranked male open-class rowers were significantly taller and heavier and had a greater sitting height (P < 0.01) than their lower-ranked counterparts. They were also more muscular in the upper body, as indicated by a larger relaxed arm girth and forearm girth (P < 0.01). For the male lightweight rowers, only proportional thigh length was greater in the best competitors (P < 0.01). In the female open-class rowers, skinfold thicknesses were lower in the more highly placed competitors (P < 0.01). In conclusion, the rowers in this sample demonstrated distinctive physical characteristics that distinguish them from non-rowers and other sports performers.  相似文献
