PASS理论在ADHD儿童评估与干预中的应用 总被引：1，自引：0，他引：1
本文从PASS理论的角度出发,分析论述了不同亚型的ADHD儿童在不同的认知加工过程中所存在缺陷注意缺陷型ADHD儿童在选择性注意过程中存在缺陷,而多动-冲动型ADHD儿童在计划过程中存在缺陷.因此,对于此类儿童的干预和矫治应当根据其特殊的认知过程缺陷采取不同的策略,从而提高其认知加工能力. 相似文献

研究选取了注意缺损多动障碍（ADHD）儿童38名,正常儿童36名,采用两项选择任务,考察在复杂任务中ADHD儿童的注意稳定性是否落后,以及反馈是否能增强ADHD儿童的注意稳定性。结果发现,（1）注意的稳定性会受到任务难度的影响。在复杂任务中,无反馈的条件下ADHD儿童的注意稳定性与正常儿童没有差异;（2）反馈对正常儿童的注意稳定性起到了积极的促进作用,即在反馈条件下,正常儿童的个体变异性减小,注意稳定性增强;但反馈并没有提高ADHD儿童的注意稳定性;（3）复杂任务中,ADHD儿童的认知加工速度落后于正常儿童。 相似文献

注意缺陷多动障碍（ADHD）是儿童常见的一种精神疾病,它有不同的亚型。反应抑制是ADHD执行功能的核心缺损,对反应抑制的研究能够帮助我们了解ADHD神经心理功能,也能够在一定程度上帮我们区分和诊断ADHD亚型。本文主要介绍了一些用于研究ADHD亚型反应抑制的常用方法,并且对于这些方法及其研究成果作了比较。 相似文献

研究选取了注意缺损多动障碍儿童34名,普通儿童36名,采用选择性注意任务,考察在目标刺激的知觉负荷高低两种情况下,注意缺损多动障碍儿童面对不同干扰程度的分心刺激时,对其的过滤能力是否落后。结果发现,注意缺损多动障碍儿童过滤分心刺激的能力是否落后取决于目标刺激的知觉负荷的高低:(1)在低知觉负荷任务中,不相容分心刺激对两组儿童的干扰程度要大于面对中性分心刺激时受到的干扰。但是注意缺损多动障碍组儿童受到的干扰效应要大于普通组儿童,说明注意缺损多动障碍组儿童过滤分心刺激的能力落后,并出现在注意选择的晚期阶段;(2)在高知觉负荷任务中,所有被试都没有因为分心刺激干扰程度的不同而受到不同的影响,即过滤中性分心刺激与不相容分心刺激的模式一样。 相似文献

The motivational styles of 25 children with attention-deficit/hyperactivity disorder, combined type (ADHD/C), 13 children with ADHD, inattentive type (ADHD/IA), and 25 nondiagnosed controls (NC) were compared using parent, teacher, and self-ratings. Both ADHD subtypes demonstrated motivational impairment characterized by a preference for easy work, less enjoyment of learning, less persistence, and a greater reliance on external than on internal standards to judge their performance relative to NC. Some motivational style differences between ADHD subtypes were also revealed, with the ADHD/C group more motivated by competitiveness and a desire to be perceived as superior to others and the ADHD/IA group less uncooperative and possibly more passive in their learning styles. When IQ was statistically controlled, these results were generally unchanged. The contributing role of motivational deficits to the generally poor academic functioning of children with ADHD is discussed, along with potential intervention implications of the divergent motivational styles of different ADHD subtypes. 相似文献

Abstract Investigation of 265 children's attitudes towards vignettes of Year 5 peers with Attention Deficit Hyperactivity Disorder (ADHD) revealed strong rejection of Hyperactive and Combined subtypes, relative to Inattentive subtypes and non‐ADHD controls. The social difficulties of children with ADHD may be understood within Barkley's theoretical model of ADHD (Barkley, 1997) that links deficits in response inhibition with four executive neuropsychological functions contributing to social cognition. The theory is also helpful in predicting strategies that may be facilitated by teacher intervention to construct improved social relationships among children with and without ADHD. 相似文献

Children with attention deficit hyperactivity disorder (ADHD) were examined on four subtests of the Test of Everyday Attention for Children (TEA‐Ch) when on and off stimulant medication. Performance was assessed relative to 18 individually age‐matched controls. Children with ADHD performed significantly worse on TEA‐Ch measures when off compared to when on stimulant medication. This was found in both predominantly inattentive (n = 6) and combined inattentive and hyperactive‐impulsive (n = 12) subtypes. The age‐matched controls significantly improved with repeated testing on most TEA‐Ch measures. Significant differences were found between the unmedicated children with ADHD and age‐matched controls on sustained attention (Score! and Walk Don’t Walk) and attention control measures (Same and Opposite Worlds). When the ADHD group was on stimulant medication, with the exception of the Walk Don’t Walk subtest, no significant differences were found between them and the age‐matched controls. Unlike the TEA‐Ch subtests, the significant differences between the two groups on the Test of Word Reading Efficiency (TOWRE) subtests remained when attentional status was altered in the children with ADHD. The study supports further investigations of the TEA‐Ch as a measure sensitive to changes in stimulant medication in children with ADHD. 相似文献

The possible utility of Wechsler's Deterioration Index (WDI) in analyzing children's Wechsler Intelligence Scale for Children-Revised (WISC-R) results was explored in this study. Clinical records of children with learning disabilities (LD) and children with attention deficit-hyperactivity disorder (ADHD) were reviewed to determine if the WDI predicted the presence or severity of the disorders. The ages of the children ranged from 6 to 14. In two independent samples of children with LD (n = 35 and n = 26), the WDI did not predict LD status or severity. The LD samples were mostly male--85% and 57%, respectively. However, the WDI scores did significantly distinguish children with ADHD (n = 10) from nondisabled children (n = 10). The results were cross-validated on an independent sample of children with ADHD (n = 17) when compared to non-ADHD children (n = 22) who experienced significant behavioral difficulties. The ADHD samples were also mostly male--90% and 89%, respectively. The WDI classified only 59% of the children with ADHD and 86% of the non-ADHD children correctly. It is recommended that the WDI be considered a developmental index rather than a deterioration index in children. It is also recommended that significant WDI elevation (greater than .20) be considered to raise the question of ADHD, rather than simply yielding a diagnosis of ADHD. 相似文献

Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to indirect informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes direct neuropsychological or academic assessment data to determine treatment efficacy. Documenting "cool" executive-working memory (EWM) and "hot" self-regulation (SR) neuropsychological impairments could aid in differential diagnosis of ADHD subtypes and determining cognitive and academic MPH response. In this study, children aged 6 to 16 with ADHD inattentive type (IT; n = 19) and combined type (n = 33)/hyperactive-impulsive type (n = 4) (CT) participated in double-blind placebo-controlled MPH trials with baseline and randomized placebo, low MPH dose, and high MPH dose conditions. EWM/ SR measures and behavior ratings/classroom observations were rank ordered separately across conditions, with nonparametric randomization tests conducted to determine individual MPH response. Participants were subsequently grouped according to their level of cool EWM and hot SR circuit dysfunction. Robust cognitive and behavioral MPH response was achieved for children with significant baseline EWM/SR impairment, yet response was poor for those with adequate EWM/ SR baseline performance. Even for strong MPH responders, the best dose for neuropsychological functioning was typically lower than the best dose for behavior. Findings offer one possible explanation for why long-term academic MPH treatment gains in ADHD have not been realized. Implications for academic achievement and medication titration practices for children with behaviorally diagnosed ADHD will be discussed. 相似文献

The study compared early literacy of Israeli children aged five to six years with and without attention deficit hyperactivity disorder (ADHD), contrasted parental writing mediation in the two groups and tested the relations between parents’ mediation characteristics and children’s early literacy skills. Each of 62 parent‐child dyads (32 with ADHD) was videotaped at home while writing words. Videotapes were transcribed and analysed for mediation (specific writing task measures, emotional measures typical of problem‐solving tasks, and general measures of interactions). Children’s early literacy (word writing, letter knowledge and phonological awareness) was assessed at home. Results showed that children with ADHD already exhibited lower literacy achievements at ages five to six compared to their peers without ADHD. Parents of children with ADHD scored lower than parents of children without ADHD on the writing‐specific, emotional and general mediation measures. In both groups, the specific writing mediation measures correlated significantly with children’s early literacy. More emotional mediation measures correlated significantly with children’s early literacy in the ADHD than in the non‐ADHD group. Discussion focused on parent‐child writing interactions as a context of early literacy development among young children with ADHD. 相似文献
