Working and Playing Together: Prediction of Preschool Social-Emotional Competence from Mother-Child Interaction 总被引:2,自引:0,他引:2
The impact of mother-child interaction on preschoolers' social-emotional competence was evaluated. Twenty-five girls and 23 boys (mean age = 44 mos) and their mothers were videotaped performing four play/teaching tasks. Preschool teachers completed the Baumrind Preschool Behavior Q-Sort and the Behar Problem Behavior Questionnaire. Mother-child interaction aggregates represented task orientation, positive emotion, and allowance of autonomy/reliance on mother. Results indicated that specific maternal interaction aggregates coherently predicted the children's Positive Social Behavior, Assertiveness, and Sadness in the preschool setting. Child aggregates were less effective predictors of teachers' ratings. Several gender differences in the prediction of social-emotional competence were found (e.g., maternal allowance of autonomy predicted girls' sadness, but boys' sadness was predicted by their own negative emotion). These findings' contributions to the parent-child literature are discussed. 相似文献

Improbable or impossible? How children reason about the possibility of extraordinary events 总被引:1,自引:1,他引:0
The present study investigated the development of possibility-judgment strategies between the ages of 4 and 8. In Experiment 1, 48 children and 16 adults were asked whether a variety of extraordinary events could or could not occur in real life. Although children of all ages denied the possibility of events that adults also judged impossible, children frequently denied the possibility of events that adults judged improbable but not impossible. Three additional experiments varied the manner in which possibility judgments were elicited and confirmed the robustness of preschoolers' tendency to judge improbable events impossible. Overall, it is argued that children initially mistake their inability to imagine circumstances that would allow an event to occur for evidence that no such circumstances exist. 相似文献

Increasing numbers of children are being born through egg donation and thus do not share a genetic relationship with their mother. Parent–infant relationship quality was examined in 85 egg donation families and a comparison group of 65 in vitro fertilization families (infant M = 11 months). Standardized interview and observational measures were used to assess mother–infant and father–infant relationship quality at the representational and behavioral levels. Few differences were found between family types in parents’ representations of the parent–infant relationship. Differences were found between family types in the observational assessment of mother–infant relationship quality, indicating less optimal interactions in egg donation families. Findings suggest that egg donation families function well in infancy overall, but there may be subtle yet meaningful differences in mother–infant interaction quality. 相似文献

Two studies investigated 4- to 7-year-olds’ knowledge about pretending. In Study 1, children (N = 66) defined pretending and described examples of own and others’ pretending. In Study 2, children (N = 52) defined pretending and then completed a battery of measures that examined their understanding that pretending involved mental states. In Study 1, older children articulated more defining features of pretending than younger children. When describing how they or others pretended, children focused on action or appearance, regardless of whether they had included more defining features in their definitions of pretending. In Study 2, the more defining features children articulated, the better their performance on the battery. We discuss the implications of these data for the role of pretending in children's developing theory of mind. 相似文献

ADHD children may have social skill deficits in at least three main areas: social communication, poor emotional regulation, and social-cognitive biases. They also have cognitive difficulties which have implications for their learning. Based on a review of the literature, it is argued that maladaptive classroom peer interactions for ADHD children may disadvantage their learning on collaborative tasks. Although the literature is sparse in the area of peer interactions and collaborative learning for ADHD children, some suggestions for practice and future research are suggested. © 1996 John Wiley & Sons, Inc. 相似文献

Transitioning into faculty roles can be a challenging experience. Responsibilities related to teaching, research, and service can be difficult to balance, and mismatch between personal preferences for work focus and instructional expectations can be problematic. This is particularly true of visiting assistant professors who want to work toward tenure-track positions, but whose current job focus is on teaching. Through transformative learning theory and employing the methodologies of self-study, we sought to understand the experiences of Kevin, the second author and a first-year visiting assistant professor. We draw data from Kevin's reflective journal and discussions between Kevin and his critical friend, Jim. Themes included (a) becoming an academic, (b) a hard-wired disposition toward work, and (c) influence of the VAP on emotional and personal health. Results are discussed through the lens of transformative learning theory and focus on Kevin's growth during his year as a visiting assistant professor. 相似文献

Wrist movements have been identified as an important factor in producing a successful golf swing, with their complex motion influencing both club head velocity and orientation. However, a detailed analysis of wrist angles is lacking in the literature. The purpose of this study was to determine kinematics across wrists and club head characteristics during the golf swing under weak, neutral and strong grip conditions. Twelve professional male golfers executed 24 shots using a driver under three grip conditions. A six degrees of freedom analysis of the hand with respect to the distal forearm was performed using a 10-camera three-dimensional motion capture system. Differences in joint angles were explored using repeated measures ANOVAs at key swing events (onset, top of backswing and impact), in addition club head velocity and clubface angle at impact were also explored. Main findings revealed significant differences in flexion/extension and internal/external rotation for both wrists at all swing events, whereas fewer significant interactions were found in ulnar/radial deviation across grips for both wrists at all events. Clubface angle only differed significantly between the weak and the strong and neural grips, presenting a more ‘open’ clubface to the intended hitting direction. This study is the first to explore tri-planar wrist movement and the effect of different grips, such analysis has implications for coaching knowledge and practice and should inform future research into different aspects of skill, technique analysis and may inform injury mechanisms/prevention. 相似文献
