Some researchers argue that the gender gap in delinquency will vary by socioeconomic status (SES); others argue instead for similarity in the gender gap in delinquency across SES. An important shortcoming of the existing research is the paucity of studies that disaggregate the data on delinquent outcomes to consider the possible impact of socioeconomic status on both the extent of overlap in predictors of females' and males' delinquency, and the extent to which these predictors help to explain the gender gap in delinquency. Using data from the National Longitudinal Study of Adolescent Health, this study addresses the shortfalls in empirical research by examining the gender gap for the juvenile population as a whole as well as across specific SES groupings, focusing on these key mediators of delinquency: grades, parental attachment, and delinquent peers. Data support the argument for similarity in the gender gap across SES, though the effect of predictors varies. 相似文献

This research investigated how teachers express links between ideas in speech, gestures, and other modalities in middle school mathematics instruction. We videotaped 18 lessons (3 from each of 6 teachers), and within each, we identified linking episodes—segments of discourse in which the teacher connected mathematical ideas. For each link, we identified the modalities teachers used to express linked ideas and coded whether the content was new or review. Teachers communicated most links multimodally, typically using speech and gestures. Teachers’ gestures included depictive gestures that simulated actions and perceptual states, and pointing gestures that grounded utterances in the physical environment. Compared to links about new material, teachers were less likely to express links about review material multimodally, especially when that material had been mentioned previously. Moreover, teachers gestured at a higher rate in links about new material. Gestures are an integral part of teachers’ communication during mathematics instruction. 相似文献

Developmental research is enhanced by use of multiple methodologies for examining psychological processes. The electroencephalogram (EEG) is an efficient and relatively inexpensive method for the study of developmental changes in brain–behavior relations. In this review, we highlight some of the challenges for using EEG in cognitive development research. We also list best practices for incorporating this methodology into the study of early cognitive processes. Consideration of these issues is critical for making an informed decision regarding implementation of EEG methodology. 相似文献

A sample of 486 children in Beijing, China, were tested on the water-level task (WLT; J. Piaget &; B. Inhelder, 1948/1956). The participants were 256 boys and 230 girls from 4th, 5th, 6th, 8th, and 11th grades. Three levels of mastery of the WLT were found. Level 1 consisted of 4th and 5th graders, who averaged about 71% correct. Level 2 consisted of 6th and 8th graders, who averaged about 83% correct. Level 3 consisted of 11th graders, who averaged 97% correct. The results provide partial support for the Piagetian theory of age-related developmental differences in performance on the WLT. The findings depict an interactive relationship of maturation with culture and education in the development of the ability to solve the WLT. 相似文献

In this paper, I explore how we might link ideas about clinical facts to current issues in child psychotherapy research. I consider what our understanding of clinical facts might contribute to our research methods and how our research methods might better represent the clinical facts. The paper introduces a selection of psychoanalytic writers' formulations of the concept and describes some of the debates about the shortcomings of the traditional style of case reporting. The importance of keeping emotional experience central in our research is discussed. I describe a research method that I believe has the potential to capture and describe some of the complicated processes of change in psychotherapy. This is the concept of the ‘turning point’ session. Introducing the paradigm of complexity theory, I briefly explore how we might think about and understand the relationship between processes revealed through detailed analysis of a single session and change over a longer period of therapy. 相似文献

Recent literature has emphasized the need to examine executive functions (EF) in children using multiple sources, including both parent rating and performance-based measures. Computerized Go/No-Go tests, including commercially available continuous performance tests (CPTs), represent one of the most commonly used methods of assessing inhibitory control—a variable central to the executive function construct. We examined the relationship between parent ratings of inhibitory control and CPT performance in two mixed clinical samples. Experiment 1 examined 109 children ages 6–18 using the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) and the Conners' CPT-II (Conners, 2000). In this sample, ratings on the BRIEF Inhibit scale (mean T-score?=?62.3) were significantly higher than the CPT-II commissions score (mean T-score?=?50.7; p < .0001); and the BRIEF and CPT-II scores were not highly correlated (r?=???.12). Experiment 2 examined a sample of 131 children ages 7–18 using the BRIEF and the Tests of Variables of Attention (TOVA; Greenberg, 1996). In this sample, parent ratings on the BRIEF Inhibit scale (mean T-score?=?56.8) were similar to TOVA commissions scores (mean T-score?=?58.6; p?=?.33), although still poorly correlated (r?=??.02). Factor analyses exploring covariance between BRIEF scales CPT-II variables (Experiment 1) and between BRIEF and TOVA (Experiment 2) yielded similar findings. In both experiments, all eight BRIEF scales loaded on a single factor, with no overlap with either the CPT-II or the TOVA. In mixed outpatient clinical samples, the BRIEF appears to measure different elements of inhibitory control than those assessed by computerized continuous performance tests. 相似文献

Discrepancies between observers are common in studies of child behavior problems that rely on behavior ratings. Although modest concordance between informants is well-documented, little is known about characteristics that predict discrepancies. In 477 children aged 5 to 12 years, maternal age and indicators of socioeconomic status (SES; maternal education, family income) were evaluated in relation to score discrepancies between the Child Behavior Checklist and Teacher Report Form for Total, Externalizing and Internalizing Problems. Family income <?$35,000 was independently associated with discrepancies in which mothers rated more clinically significant child behavior problems than teachers for Total, Externalizing and Internalizing Problems [odds ratio (OR)?=?3.26, 95 % confidence interval (CI), 1.19–8.96, OR?=?2.76, 95 % CI 1.03–7.34 and OR?=?3.07, 95 % CI 1.30–7.26, respectively]. Maternal education was not associated with discrepancies, but younger mothers were less likely to rate child’s behavior in the clinical range for Externalizing Problems than teachers (OR per year of age?=?0.88, 95 % CI 0.81–0.96). These results suggest that studies that utilize only maternal or teacher report of child behavior may have misclassification of outcomes that is dependent on SES and could produce biased results. 相似文献

This study examined the effects of sex referent cues for the estimation of success, as well as actual performance on a simple motor endurance task. Boys and girls in grades 3 and 5 (N = 160) were randomly assigned to one of three referent groups or a control group. Subjects in the referent groups were given an identical referent score, (48), presented in three different forms: the average score for boys, the average score for girls, and the average score for children. The control group was given no referent score. Subjects were required to estimate their own success and then perform a timed side-to-side jump over a rope. Results suggest that as girls increase in age there is a decrease in their confidence in performing motor skills. Further, boys and girls at the two grade levels responded differently to the sex referent cues. 相似文献
