Twenty-nine children with a diagnosis of Attention Deficit Hyperactive Disorder (ADHD) were compared to a group of 21 emotionally disturbed (ED) children and a control group (CO) of 20 nonproblem children. The meaures used in the comparison were the 12 subtests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Stroop Color and Word Test (SCWT). The results showed that the CO group was superior to the ADHD and ED groups and that the ED group performed better than the ADHD group on most of the variables. A stepwise discriminant function analysis showed that similar WISC-R subtests differentiated between the ADHD group and the ED and CO groups. Two measures of the SCWT helped in discriminating between the ADHD and ED groups, but not between the ADHD and CO groups. The authors discuss the meaning of these findings and their contribution to better understanding of the ADHD group, its specific cognitive processing, and its problems. 相似文献

《Scientific Studies of Reading》2013,17(3):261-283
Recently a gene, termed EKN1, has been identified because of a chromosomal breakpoint that occurred in this gene. This chromosomal breakpoint was found in 4 family members that had specific reading disabilities (RDs), indicating that disruption of this gene may be contributing to the risk of developing RDs. This gene was further supported as contributing to RD by association studies. Because of the evidence from twin studies for shared genetic factors contributing to RD and attention deficit hyperactivity disorder (ADHD), particularly inattention symptoms, we investigated the relationship of DNA markers in this gene to ADHD and ADHD symptoms in a sample of 186 nuclear families (probands, their parents, and affected siblings) collected through a proband with ADHD. We used 6 polymorphic DNA markers located across the gene, including the 2 markers previously reported to be associated with RD in a Finnish sample and a marker associated with RD in a sample of families collected in Toronto. We found a trend for association for several markers to the ADHD phenotype analyzed as a categorical trait using the transmission disequilibrium test and significant evidence for biased transmission of the haplotypes containing these markers, χ2(3) = 9.312, p =. 025. Using quantitative analysis, we observed evidence for association of one of the haplotypes to the inattention and hyperactive/impulsive symptom dimensions as reported by parents and to the inattention symptoms as reported by teachers, as well as a trend for association with the reading phenotypes of word identification and decoding. The results provide preliminary support for the role of the EKN1 chromosomal region in ADHD, suggesting that this region may contribute to ADHD symptoms in addition to RD. 相似文献

This article describes a longitudinal analysis of the behavior of a birth cohort of 435 boys. 4 groups were defined at age 13 on the basis of both self-reported delinquent behavior and professional diagnosis of Attention Deficit Disorder: ADD + delinquent, ADD only, delinquent only, and nondisordered. Biennial correlates of delinquency (antisocial behavior problems, verbal intelligence, reading difficulty, and family adversity) were traced across childhood. The ADD + delinquent boys consistently fared the worst on the assessments of family adversity, verbal intelligence, and reading. Their antisocial behavior began before school age, escalated at school entry, and persisted into adolescence. The ADD-only boys had normal family, intelligence, and reading scores, and showed only mild antisocial behavior in middle childhood. The delinquent-only boys showed no early risk from family, low intelligence, or reading deficit, and remained relatively free of conduct problems until they initiated delinquency at age 13. Persistence of criminal offending beyond adolescence is predicted for the ADD + delinquent boys. 相似文献

RNAi是与靶基因序列同源的双链RNA(dsRNA)所诱导的一种特异性基因沉默现象。RNAi是生物体进化过程中抵御外来基因和病毒感染的进化保守机制,是真核生物中存在的一种抗病毒入侵、抑制转座子活动、调控基因表达的监控机制,具有重大生物学意义。RNA干扰技术的发现及其作为基因敲除工具在模式生物、哺乳动物细胞和体内的成功应用的例子确保了它在药学研究中的作用。越来越多的研究显示RNAi在药物研发中显示出极大潜力,目前已有部分RNAi药物进入临床试验阶段。本文将从两个方面来论述RNAi在药学的应用:一是RNAi在药物靶点鉴定中的运用;二是siRNAs作为药物在疾病治疗中的作用。 相似文献

Changes in visual attention and story comprehension for children (N = 132) with attention deficit hyperactivity disorder (ADHD) and comparison peers were examined. Between the ages of 7 and 9 (Phase 1) and approximately 21 months later (Phase 2), children viewed 2 televised stories: 1 in the presence of toys and 1 in their absence. Both groups of children showed developmental increases in visual attention and stable group differences over time. Deficits in comprehension among children with ADHD, however, increased over time. Whereas comparison children’s recall of factual and causal information increased over time in both viewing conditions, children with ADHD showed no developmental improvement in recall of factual information in the toys‐present condition and no improvement in recall of causal relations in either viewing condition. 相似文献

Using activity systems analysis to identify inner contradictions in teacher professional development
This study took place in the United States and explored teacher perspectives on the situational factors that influence their professional development using Engeström's (Engeström, Y. (1987). Learning by expanding: An activity-theoretical approach to developmental research. Helsinki: Orienta-Konsultit Oy) four levels of inner contradictions in activity systems analysis. In this process, we addressed the question: what do teachers perceive as sources of conflicts in their professional development? Semi-structured interviews with participants were the primary data source in this study. By using this analysis method, the findings indicated that teachers perceived that their motivation and goals for participating in professional development were not in alignment with their school district and universities that designed and facilitated professional development activities. This misalignment contributed to various situational challenges that became obstacles for teachers to improve their classroom practices through curricular-based interventions. 相似文献

Some researchers suggest that having a learning disability (LD) may act as a risk factor, increasing the likelihood that adolescents experience more negative outcomes in many areas of their lives. However, researchers have yet to examine in one study how having LD with and without attention deficit hyperactivity disorder (ADHD) is related to a comprehensive set of psychosocial variables across a diverse set of domains (e.g., peer, family, school, intrapersonal). The purpose of the present study was to address that limitation by comparing the perceptions of adolescents with LD (N= 230), with comorbid LD/ADHD (N= 92), and without LD or ADHD (N= 322) regarding their academic orientation, temperament, well‐being, loneliness, parental relationships, victimization, activities, and friendships. Results are consistent with the hypothesis that LD may indeed act as a risk factor increasing the likelihood of more negative outcomes. The results also indicate that for some psychosocial variables this likelihood may be increased in adolescents with comorbid LD/ADHD. The findings have important implications for stakeholders concerned about supporting adolescents with LD with and without comorbid ADHD. 相似文献

This study assesses information processing and memory functioning in 50 children diagnosed with Attention Deficit Hyperactive Disorder (ADHD) with and without learning disabilities (LD). Mode of presentation (visual vs. auditory), type of memory processing (immediate, short-term, and long-term), and order of recall (ordered vs. unordered) were assessed using the Learning Efficiency Test-II (LET-II). Both groups demonstrated difficulty with auditory ordered recall and lost substantial information from immediate memory to short-term and long-term memory stores. The ADHD/LD group also demonstrated more difficulty with ordered recall than the ADHD only group. While there were no differences between the two groups in regard to immediate recall, the ADHD/LD group demonstrated more problems transferring information into short-term and long-term memory stores than the ADHD only group. Verbal interference effects significantly decreased retention for both visual and auditory processing. Results indicate that ADHD alone presents significant problems in information processing, but the comorbid effects of a learning disability further intensify the negative impact of ADHD. © 1996 John Wiley & Sons, Inc. 相似文献

Little is known regarding sources of diagnostic error at the provider level in cases of possible child physical abuse. This study examines medical diagnosis as part of medical management and not as part of legal investigation. Simulation offers the opportunity to evaluate diagnostic accuracy and identify error sources. We aimed to identify sources of medical diagnostic error in cases of possible abuse by assessing diagnostic accuracy, identifying gaps in evaluation, and characterizing information used by medical providers to reach their diagnoses. Eight femur fracture simulation cases, half of which were abuse and half accident, were created. Providers from a tertiary pediatric emergency department participated in a simulation exercise involving 1 of the 8 cases. Performance was evaluated using structured scoring tools and debriefing, and qualitative analysis characterized participants’ rationales for their diagnoses. Overall, 39% of the 43 participants made an incorrect diagnosis regarding abuse. An incorrect diagnosis was over 8 times more likely to occur in accident than in abuse cases (OR = 8.8; 95% CI 2 to 39). Only 58% of participants correctly identified the fracture morphology, 60% correctly identified the mechanics necessary to generate the morphology, and 30% of ordered all appropriate tests for occult injury. In misdiagnoses, participants frequently falsely believed the injury did not match the proposed mechanism and the history provided by the caregiver had changed. Education programs targeting the identified error sources may result in fewer diagnostic errors and improve outcomes. The findings also support the need for referral to child abuse experts in many cases. 相似文献

A four-test short form of the WISC-R was developed on the basis of both rational and statistical criteria, using data from the representative standardization sample. The short-form comprised Arithmetic and Vocabulary from the Verbal Scale along with Picture Arrangement and Block Design from the Performance Scale. Various psychometric properties of the abbreviated battery were defined, and indicators of the short form's accuracy in predicting Full-Scale IQ (the standard error of estimate, effectiveness in classifying a child's intelligence level) were provided. A major topic of discussion was the use and abuse of short forms. 相似文献

So as to compare the results of the WISC and WISC-R, both instruments were administered to 58 children randomly selected from a school population of 583. All administration and scoring was performed by the same psychologist, with a two-month interval separating the administrations for each child. All IQs were significantly higher (p <.01) on the WISC, with the Performance difference being greater than the verbal difference. Also, 8 of the 10 required subtest scaled scores were significantly greater (p <.05) on the older instrument. Regression equations were obtained to predict WISC-R IQs from WISC scores. 相似文献
