我国近十年来汉语阅读障碍研究回顾与展望

发展性阅读障碍（developmentaldyslexia,DD）是一种严重的学习障碍。文章回顾了l996~2006年间中国内地作者发表的有关汉语DD的实证性文章,发现我国学者近十年来对汉语DD的研究主要包括DD的诊断筛选、亚型分析、认知特点和认知神经机制研究、教育干预等几个方面。文章同时探讨了现有研究中存在的不足,如诊断标准不统一;研究领域比较狭窄;缺乏有效的干预模式和实证研究等,最后提出了研究的发展趋势和未来研究方向     

Further evaluation of emerging speech in children with developmental disabilities: training verbal behavior

The conceptual basis for many effective language-training programs are based on Skinner's (1957) analysis of verbal behavior. Skinner described several elementary verbal operants including mands, tacts, intraverbals, and echoics. According to Skinner, responses that are the same topography may actually be functionally independent. Previous research has supported Skinner's assertion of functional independence (e.g., Hall & Sundberg, 1987; Lamarre & Holland, 1985), and some research has suggested that specific programming must be incorporated to achieve generalization across verbal operants (e.g., Sigafoos, Reichle, & Doss, 1990). The present study provides further analysis of the independence of verbal operants when teaching language to children with autism and other developmental disabilities. In the current study, 3 participants' vocal responses were first assessed as mands or tacts. Generalization for each verbal operant across alternate conditions was then assessed and subsequent training provided as needed. Results indicated that generalization across verbal operants occurred across some, but not all, vocal responses. These results are discussed relative to the functional independence of verbal operants as described by Skinner.     

Assessment of the functions of vocal behavior in children with developmental disabilities: a replication

Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the methodology developed by Lerman et al. Participants were 4 children who had been diagnosed with developmental disabilities and who engaged in limited vocal behavior. The function of vocal behavior was assessed by exposing target vocal responses to experimental analyses. Results showed that experimental analyses were generally useful for identifying the functions of vocal behavior across all participants.     

早期经验对繁衍策略形成与发展的影响

很多发展心理学家探讨了早期经验与心理行为发展的关系,但这些发展心理学家较少以进化理论为指导来探讨不同发展阶段的心理行为特点。比如,配偶选择、性交往与父母教养等成果颇丰的研究领域均缺少以进化理论为基础的理论解释。与主流的发展心理学研究不同,Draper和Harpending (1982),Ellis (2004),Chisholm (1996) 和Belsky等(1991)以进化理论为基础探讨了早期经验与繁衍策略对儿童心理行为发展的影响。进化观点认为儿童在家庭中获得的早期经验会影响身体发育与未来的繁衍策略。Ellis（2004）已经证实女性青春期确实与早期家庭经验有关     

学前儿童现实性监测的发展变化

对3～5岁儿童对与他人（而非自我）有关的互动性动作的现实性监测的发展变化进行了考察。结果表明：学前儿童更多地将想象的动作错误地记忆为真实的动作,而不是相反——这就是所谓的现实性监测错误的不对称现象;虽然儿童总体的现实性监测能力在学前期得到了持续和稳定的发展,但这种发展主要体现在对想象动作的现实性监测的发展上。这一结果对学前儿童目击者证词的准确性具有重要的启示意义。     

阅读障碍儿童汉字认知特点研究

运用多重评估法从760名小学3年级学生中选取了30名阅读与记字困难学生和30名正常学生为被试,分别研究了儿童视觉能力、听知觉能力和字形-音及字形义通道联结能力的识字认知特点。研究结果表明,阅读障碍儿童基本语音辩别能力不存在落后,而在视觉辨别、字形长时记忆、语音短时记忆以及形音和形义联结长时记忆上都存在程度不同的落后。研究还发现,阅读障碍儿童具有对汉字做浅层次机械加工和视觉加工的倾向。     

After-School Youth Development Programs: A Developmental-Ecological Model of Current Research

Although there has been a rapid increase in funding and attention to after-school programs, there is little understanding of how after-school programs impact children's developmental trajectories. The heterogeneity of American children makes it very unlikely that all children need after-school programming or that there is but one brand of after-school programming suitable for all youth. We discuss the numerous developmental and contextual factors that may influence which children benefit most from after-school programs as well as the nature of the after-school programs most beneficial to children's needs. The value of utilizing an ecological and developmental perspective to after-school program evaluation are presented, including the need for improved research designs and more detailed analyses of program type and services as well as a more complete determination of which children benefit the most from after-school participation.     

Enhancing frequency recording by developmental disabilities treatment staff

We evaluated a staff training and management package for increasing accuracy of recording frequency of problem behavior in a residential care facility. A multiple baseline design across the first and second work shifts showed that 2 of 8 participants increased their accuracy following in-service training, and all 8 improved during a condition with supervisor presence and feedback. Improvements were maintained when feedback was removed and generalized to activity periods when neither supervisor presence nor feedback was provided. Other staff behavior was not adversely affected by the intervention package.     

Assessment of deviant arousal in adult male sex offenders with developmental disabilities

Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed.     

Training play behavior in a 5-year-old boy with developmental disabilities

The purpose of the current study was twofold: (a) to investigate if it was possible to train three different games (both as a leader and as a participant) to a child with developmental disabilities through interaction with 4 typically developing peers, and (b) to examine if correct responding would be maintained after the training was faded. A multiple probe design across three games was used. The results showed that the child learned both skills as a leader and as a participant in all three games, and that skills were maintained for a period of 3 weeks after the training had stopped.
