The Relation of Story Structure Properties to Recall of Television Stories in Young Children with Attention-Deficit Hyperactivity Disorder and Nonreferred Peers

In this study, the authors examined memory for televised stories to gain insight into similarities and differences in story comprehension between young children with attention-deficit hyperactivity disorder (ADHD) and their typical peers. In particular, the authors investigated the extent to which 4- to 6-year-old children's free recall of story events is predicted by several structural properties of story events (number of causal connections, whether an event is on or off the story's causal chain, story-grammar category, and position in the story's hierarchical structure), whether differences exist between children with ADHD and nonreferred comparison children in their sensitivity to structural features of stories, and whether age differences in sensitivity to structural features are similar for both groups. For both groups, recall of story events was predicted by all four structural properties, but the effects of the two causal properties was stronger for comparison children than for children with ADHD. Further examination revealed that this difference was observed only when a competing activity was available during television viewing. These findings indicate that both groups of preschool children are able to benefit from causal structure when recalling television stories, but that children with ADHD lose this benefit when attention is divided. Consistent with previous findings for nonreferred children (P. W. van den Broek, E. P. Lorch, & R. Thurlow, 1996), in both diagnostic groups the effects of causal properties increased across age, and older children were more likely to include causally important protagonists' goals in their recalls than younger children.     

Long-Term Follow-Up of Children with Mental Retardation/Borderline Intellectual Functioning and ADHD

Fifty-two children (ages 7 to 14 years) with moderate mental retardation to borderline intellectual functioning were recontacted 12 to 65 months following participation in a double-blind, placebo-controlled trial of methylphenidate (MPH). Sixty-nine percent of subjects continued to be prescribed medication for behavior control at follow-up. While 72% of the sample evidenced improvement, over two-thirds continued to be rated at or above the 98th percentile on the Hyperactivity Index of the Parent Conners. In fact, 22% of subjects had received inpatient psychiatric treatment between the time of the initial MPH trial and follow-up. Finally, subjects with high initial ratings on the Parent Conners Conduct Problems scale were more likely to be suspended from school or receive inpatient psychiatric treatment than subjects with low initial ratings. The results suggested that children with ADHD and mental retardation or borderline intellectual functioning continued to exhibit significant symptoms associated with attention deficit hyperactivity disorder (ADHD) at follow-up and that early conduct problems were predictive of continuing behavioral difficulties.     

小脑与发展性阅读障碍

发展性阅读障碍是学龄儿童面临的学习问题之一。近年来,许多行为和神经生理学、影像学实验都发现,发展性阅读障碍的儿童有明显的运动功能失调,如平衡性差、身体灵敏度不够以及自动化水平低。Nicolson等人提出的小脑理论认为,阅读障碍者的小脑功能失调影响了书写及发音,导致语音及阅读能力不足,而且小脑与时间控制有关,阅读障碍者的时间估计能力有缺陷与他们的小脑功能失调有关。本文回顾了有关小脑理论的研究,并指出小脑的认知功能还有待进一步的研究。     

正常与多动儿童的创造力、学习适应性比较研究

本研究比较ADHD儿童和正常儿童在创造性思维测验、学习适应性测验以及教师对其创造力评价上的差异。结果表明：(1)ADHD儿童和正常儿童在数字和图形创造性思维测验上的成绩没有显著的差异。表明ADHD和创造力是彼此独立的两个特质;(2)ADHD儿童在学习态度、学校环境(主要是师生关系和同伴关系)、独立性和毅力等维度上明显偏低;(3)不同学科教师对于ADHD儿童和正常儿童在创造力水平高低的评价上没有显著性差异;(4)对于正常儿童。不同学科教师对其创造力的评价与儿童在创造力测验上的得分呈显著性相关;对于ADHD儿童则没有显著性相关。     

Neurofeedback and the Brain

Neurofeedback is an emerging neuroscience-based clinical application, and understanding the underlying principles of neurofeedback allows the therapist to provide referrals or treatment, and provides clients with a framework for understanding the process. The brain's electrical patterns are a form of behavior, modifiable through “operant conditioning,” with the excessive brain frequencies reduced, and those with a deficit are increased. The learning curve for EEG has been described (Hardt, 1975).     

Temperament, ADHD and peer relations among schoolchildren: the mediating role of school bullying

The goal of the study is to investigate the link between temperament, attention-deficit hyperactivity disorder (ADHD) symptoms, social preference, bullying and victimization. The study sample consisted of 195 children attending the fourth and fifth grade (age 8-10), their mothers and their teachers. A multiinformant approach was used: mothers were interviewed about the temperament of their children; teachers were asked about ADHD symptoms; children responded to a peer nominations inventory designed to investigate their roles as bullies and/or victims and their social preferences (liked and disliked peers). A Structural Equation Model multigroup analysis (males and females) was used to test the relationships among variables hypothesized by the authors. The analysis showed that temperamental variables have a direct relation to ADHD symptoms, that ADHD has a direct relation to bullying behavior in males and to victimization in females and that bullies and victims are less well accepted than peers who belong to neither category. ADHD has only an indirect relation to social preference through the mediating role of school bullying.     

Selective attention and inhibitory deficits in ADHD: Does subtype or comorbidity modulate negative priming effects?

Selective attention has durable consequences for behavior and neural activation. Negative priming (NP) effects are assumed to reflect a critical inhibitory component of selective attention. The performance of adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) was assessed across two conceptually based NP tasks within a selective attention procedure. Comorbidity (non-comorbid ADHD vs. comorbid ADHD) and subtype (ADHD combined vs. ADHD inattentive) were considered key issues. Results found NP effects to differ as a function of comorbidity but not subtype. Findings are discussed in light of functional neuroimaging evidence for neuronal enhancement for unattended stimuli relative to attended stimuli that strongly complements an inhibitory-based explanation for NP. Implications for the ‘AD’ in ADHD and contemporary process models of the disorder are considered.     

Children with ADHD in Residential Care

Little is known about the characteristics or functioning of children with ADHD in residential care as compared to their non-ADHD peers. This study evaluated data on 538 children with (n = 125) and without (n = 413) ADHD in residential care to determine demographic, mental health, behavioral, and treatment (i.e., medication use) characteristics. Results revealed that both groups presented elevated risks, however, scores for children with ADHD indicated even greater levels of need. Specifically, differences were found between the two groups on demographics (e.g., family reunification status, restrictiveness of prior out-of-home placements), behavior (e.g., attention problems, rule-breaking and aggressive behaviors) and medication status. Findings suggest there is a need for aftercare services to help support families as children transition from care, interventions to address behavior, and medication management through assessment and monitoring.

国内注意缺陷/多动障碍儿童干预效果的元分析

对国内过去12年间的62项注意缺陷/多动障碍干预研究结果进行了元分析,结果显示：（1）国内现有的ADHD干预措施取得了显著的干预效果;（2）在不同干预措施中,药物治疗与行为疗法或认知行为疗法相结合具有最佳疗效,单独的药物治疗次之,单独的行为疗法或认知行为疗法效果较低;（3）在各种效果指标中,学业指标上的效果量是最大的,这一结果与国外已有的元分析研究发现不一致;（4）在各种效果信息来源中,来自客观观察的效果量最高,来自父母评价的效果量次之,来自教师评定的效果量最差。（5）各种干预措施在不同效果指标上有不同的表现。药物治疗对于学业和行为指标的效果最强烈,而认知行为疗法和脑电反馈疗法对认知指标的效果最明显。最后,结合干预措施的选择、效果指标的采用以及研究质量问题进行了讨论
