问题解决中图式的建构:一项应用题分类研究   总被引:2,自引:0,他引:2  
以小学三、四年级的60名儿童为被试,采用对基本算术应用题分类的方法测量图式,探讨了图式的作用以及影响图式获得的因素。结果表明,被试对问题的分类有前图式水平、图式水平、按解题程序分类三种情况,前两个水平又分成若干亚水平;图式的水平对问题解决成绩有预测作用;图式的水平和问题解决成绩均有显著的性别差异,女生优于男生。  相似文献

小学一~三年级儿童加减法策略选择的发展特点研究   总被引:6,自引:3,他引:3  
随机选取90名小学一~三年级的儿童为被试,采用实验法和访谈法对儿童解决加减法算术题的策略发展特点进行了探讨。结果发现:1儿童能运用多种策略解决加减法算术题,在解决两个数的算术题时用到了13种策略,在解决三个数的算术题时用到了8种策略。2儿童在解决同一道题时大多能同时运用两种或两种以上的策略。3随着年龄的增长,儿童使用策略的总目呈简约化发展的趋势。4在解决两个数的算术题时,不同年级的儿童在使用出声策略、拆十策略、手势策略、逆算策略、数数策略的次数上差异显著,随着年级的增长其使用频率逐渐降低。5儿童在解决三个数的算术题时,各年级儿童使用出声策略、手势策略、对位策略差异显著,随着年级的增长其使用频率逐渐增高。  相似文献

The Anxiety, Depression, Anger, Disruptive Behavior, and Self-Concept Inventories of the Beck Youth Inventories of Emotional and Social Impairment (J. S. Beck, A. S. Beck, & J. Jolly, 2001) were administered to 150 female and 150 male outpatients who were 7–12 years old and matched by sex as to whether they were diagnosed with anxiety, mood, adjustment, or attention-deficit and disruptive behavior disorders to determine whether each inventory represented distinct symptom dimensions. Horns parallel analyses (J. L. Horn, 1965) found that the Anxiety, Depression, and Disruptive Behavior Inventories were unidimensional, but that the Anger and Self-Concept Inventories were each composed of two underlying dimensions. Iterated principal-factor analyses indicated that the Anger Inventory represented Affective and Cognitive dimensions, whereas the Self-concept Inventory reflected Self-Esteem and Competency dimensions. However, the overall pattern of results was discussed as supporting the current practice of scoring each inventory as a summative scale for clinical assessment purposes.  相似文献

Fifteen children with selective mutism (SM), 15 children with anxiety disorders (AD) without selective mutism, and 15 children without anxiety disorders or selective mutism (CN) were compared to examine the relationship between selective mutism and anxiety. Data were collected from children (age 4–10 years), parents, teachers, and clinicians. Results indicated that children with SM closely resemble children with AD. All children with SM received a diagnosis of social anxiety disorder and 53% received a diagnosis for an additional anxiety disorder. In addition, the SM and AD groups differed substantially from controls with respect to parent- and teacher-rated internalizing behavior problems. No differences among the groups were found with respect to parent-and teacher-reported externalizing behavior problems. The results are consistent with prior research emphasizing the association between selective mutism and anxiety disorders, and suggest that selective mutism may be conceptualized, assessed, and treated as an anxiety-related problem.  相似文献

Wide discrepancies exist concerning the reported occurrence of sleep problems for elementary school children. We describe parental perception of sleep problem behavior in elementary school aged children 5–12 years. Approximately 4% of parents reported their children experienced significant global sleep problems serious enough to adversely affect family functioning. Significant specific sleep problems reported by parents occurred for approximately 9–14% of the children in the sample. These ranges were in the low end of the ranges of sleep problems reported in previous literature for this age group.  相似文献

The Role of Temperament in the Etiology of Child Psychopathology   总被引:16,自引:0,他引:16  
A substantial proportion of children and adolescents come to suffer from psychological disorders. This article focuses on the temperament factors that are involved in the pathogenesis of child psychopathology. It is argued that besides the reactive temperament factor of emotionality/neuroticism, the regulative process of effortful control also plays an important role in the etiology and maintenance of internalizing and externalizing problems in youths. More specifically, vulnerability to child psychopathology is determined by a temperament that is characterized by high levels of emotionality/neuroticism and low levels of effortful control. Models are hypothesized in which reactive and regulative temperament factors either have interactive or additive effects on the development of psychological disorders in children, and conceptualized in terms of a developmental psychopathology perspective. Directions for future research and clinical implications of this temperamental view on psychopathology are discussed.  相似文献

A number of measures have been used in epidemiological studies of children's exposure to community violence, yet the quality of these instruments is not uniformly good. This paper undertakes a systematic review of the most commonly used (or most promising) self-report or interview-administered instruments, with regard to their conceptual bases and psychometric properties. Based on the review, recommendations are made for working with the current state of the science in order to move the field forward. A key recommendation is for sounder conceptualization of work in the field and greater transparency in the reporting of research, in order to facilitate the comparability of studies.  相似文献

This study evaluated the validity of mediating pathways in predicting self-assessed negative affect from shyness/social withdrawal, peer rejection, victimization by peers (overt and relational), and the attitude that aggression is legitimate and warranted. Participants were 296 3rd through 5th graders (156 girls, 140 boys) from 10 elementary schools. Self-report measures of victimization, attitudes, and negative affect, and a teacher-report measure of shyness/social withdrawal and peer rejection were completed during the spring semesters of 2 consecutive years. Hierarchical regression analyses supported the mediational model in predicting negative affect at Time 2. However, an increase in negative affect over the 12-month study period was best accounted for by direct effects of increased victimization and changes in attitudes/attributions regarding aggression. Implications for the planning of school interventions designed to interrupt these victimization-maladjustment pathways are discussed.  相似文献

Used linguistic analysis of written narratives of caregivers of hospitalized youth with chronic illness to identify emotional and cognitive processes related to physical and psychological health outcomes following writing. Measures were administered at baseline and 4 months. Experimental group (n = 29) wrote about traumas whereas the control group (n = 24) wrote about summer activities for 20 min on three different days. Compared groups on negative emotion- and cognition-related word use. Tested change in negative emotion- and cognition-related word use as predictors of outcomes in experimental group. Consistent with hypotheses, experimental group used more negative emotion words [F(1, 53) = 77.55, p < .001] and cognition-related words than control group [F(1, 53) = 19.09, p < .001] and an increase in cognition words predicted Physical Health Summary Score on SF-36 (standardized = .37, p < .05). A decrease in negative emotion words was related to Physical Health Summary Score on SF-36 only when entered into regression with change in cognition words (standardized = –.31, p < .05). A decrease in negative emotion together with an increase in cognitive processing facilitated by written emotional disclosure has beneficial effects on physical health-related quality of life.  相似文献

We evaluated computerized training and testing programs with children who were having difficulties learning prereading skills. The programs were derived from equivalence research and were written in authoring software designed for educators. After learning to match uppercase and lowercase printed letters to the corresponding letter names (Tasks 1 and 2), the children matched the letters to one another (Tasks 4 and 5). Then, after learning to match uppercase letters to sounds (Task 3), they also matched lowercase letters to sounds (Task 6) and matched printed to spoken words (Tasks 7 and 8). The results recommend equivalence-based protocols and user-friendly software in further development of prereading instruction.  相似文献
