What do children with autism attend to during imitation tasks?

Individuals with autism show a complex profile of differences in imitative ability, including a general deficit in precision of imitating another’s actions and special difficulty in imitating nonmeaningful gestures relative to meaningful actions on objects. Given that they also show atypical patterns of visual attention when observing social stimuli, we investigated whether possible differences in visual attention when observing an action to be imitated may contribute to imitative difficulties in autism in both nonmeaningful gestures and meaningful actions on objects. Results indicated that (a) a group of 18 high-functioning 8- to 15-year-olds with autistic disorder, in comparison with a matched group of 13 typically developing children, showed similar patterns of visual attention to the demonstrator’s action but decreased attention to his face when observing a model to be imitated; (b) nonmeaningful gestures and meaningful actions on objects triggered distinct visual attention patterns that did not differ between groups; (c) the autism group demonstrated reduced imitative precision for both types of imitation; and (d) duration of visual attention to the demonstrator’s action was related to imitation precision for nonmeaningful gestures in the autism group.     

Attention to low- and high-spatial frequencies in categorizing facial identities, emotions and gender in children with autism

This study was aimed at investigating face categorization strategies in children with autistic spectrum disorders (ASD). Performance of 17 children with ASD was compared to that of 17 control children in a face-matching task, including hybrid faces (composed of two overlapping faces of different spatial bandwidths) and either low- or high-pass filtered faces. Participants were asked to match faces on the basis of identity, emotion or gender. Results revealed that children with ASD used the same strategies as controls when matching faces by gender. By contrast, in the identity and the emotion conditions, children with ASD showed a high-pass bias (i.e., preference for local information), contrary to controls. Consistent with previous studies on autism, these findings suggest that children with ASD do use atypical (local-oriented) strategies to process faces.     

Diagnostic and Assessment Findings: A Bridge to Academic Planning for Children with Autism Spectrum Disorders

Increasing numbers of children diagnosed and treated for autism spectrum disorders (ASDs) has impacted both neuropsychologists and educators. Though both play key evaluative and treatment roles, there is no available method or process in place enabling the translation of the neuropsychological report recommendations into a format educational teams can easily use, leading to a gap between neuropsychological recommendations and educational planning. In the following, we review the areas evaluated by a neuropsychologist when assessing a child with an ASD, discuss the domains targeted by educational teams when designing an educational plan, and then present a process that has met with some success creating a "bridge" between the diagnostic/assessment process and the subsequent academic planning. Though presented in the context of ASD, the process described can be used by neuropsychologists for various populations to facilitate partnerships with educators that result in improved care for the child.     

The ‘Fractionable Autism Triad’: A Review of Evidence from Behavioural,Genetic, Cognitive and Neural Research

Autism is diagnosed on the basis of a triad of impairments in social interaction, communication, and flexible imaginative functions (with restricted and repetitive behaviors and interests; RRBIs). There has been a strong presumption that these different features of the syndrome are strongly intertwined and proceed from a common cause at the genetic, cognitive and neural levels. In this review we examine evidence for an alternative approach, considering the triad as largely ‘fractionable’. We present evidence from our own twin studies, and review relevant literature on autism and autistic-like traits in other groups. We suggest that largely independent genes may operate on social skills/impairments, communication abilities, and RRBIs, requiring a change in molecular-genetic research approaches. At the cognitive level, we suggest that satisfactory accounts exist for each of the triad domains, but no single unitary account can explain both social and nonsocial features of autism. We discuss the implications of the fractionable-triad approach for both diagnosis and future research directions.     

运用沙箱游戏区分自闭症谱系障碍儿童功能的可行性探索

摘 要： 通过沙箱作品来解读研究对象的内心世界是为常见,然根据其作品来区分自闭症谱系障碍（ASD）儿童功能的研究尚少,本研究力图为此进行探索。通过对126名已有医院诊断书的3.2~14岁ASD儿童的沙箱游戏行为、微缩玩具摆放过程观察及作品分析发现,ASD儿童功能越高,其沙箱游戏总分和沙箱游戏各观察维度的得分也越高,差异显著性均达到p<.001。ASD儿童功能越高,其沙箱作品的整合性、空间布局和想象力水平也越高。运用沙箱游戏或可区分ASD儿童的功能。     

The effectiveness of function‐based interventions to treat sleep problems,including unwanted co‐sleeping,in children with autism

This study investigated the effectiveness of functional behavioral assessment (FBA)—informed interventions for sleep problems, particularly co‐sleeping, in children with autism spectrum disorder (ASD). Seven children, who exhibited multiple sleep problems including unwanted co‐sleeping, participated. FBA, based on information derived from interviews and parent‐recorded sleep diaries, was used to develop individualized case formulations upon which multicomponent, parent‐implemented interventions were based. These were evaluated using a single‐case, non‐concurrent multiple‐baseline‐across‐participants design. Improvements were observed across all sleep problems, including the elimination of co‐sleeping. Gains were maintained at follow‐up for five out of seven children, though two children did not complete intervention. Parents reported high levels of satisfaction with the program. FBA‐based interventions for sleep problems in children with ASD and their clinical implications are further discussed.     

工作场所领导愤怒的有效性及其作用机制

领导愤怒(leader anger)作为最常见、最易被感受到的工作场所负面情绪之一, 对于改善工作关系、行为和绩效具有显著影响。然而, 已有文献关于领导愤怒阻碍还是促进领导有效性的观点存在许多争议, 对于领导愤怒为什么以及何种条件下影响领导有效性的问题尚不明确。在回顾工作场所领导愤怒概念起源和内涵特点的基础上, 从消极效应和积极效应双刃视角厘清了工作场所领导愤怒的有效性, 基于情绪即社会信息理论阐释了工作场所领导愤怒有效性的双路径中介机制, 并从个体/团队/组织三层面分析了领导愤怒有效性的边界条件。未来研究应从工作场所领导愤怒的概念和结构测量、事件前因和后果、中介机制、情境因素、研究方法和研究层面等方面进一步拓展。     

自闭症谱系障碍个体的焦虑：发生机制、评估与治疗

自闭症谱系障碍是一种神经发育性障碍, 主要表现为社会交往互动障碍和重复刻板性行为。焦虑或焦虑障碍常被认为是自闭症个体最普遍的共病之一。焦虑与自闭症之间的关系尚不明确, 自闭症个体的焦虑与无法忍受不确定性、杏仁核功能和体积、情绪调节策略、消极思维存在一定关联; 目前已经开发出专门用于自闭症个体焦虑的评估工具; 修订版认知行为疗法对自闭症个体焦虑的治疗取得了良好效果。未来的研究应着重探索自闭症个体焦虑的认知与神经机制, 检验专用评估工具的有效性, 继续关注现代技术(如虚拟现实技术)对自闭症个体焦虑的治疗效果。     

自闭症儿童对情景事件的情绪理解：基于内隐和外显的测量

该研究旨在采用生态效度更高的情绪情景事件以及内隐和外显两种测量方式考察自闭症儿童的情绪理解。选取自闭症和智商匹配的正常儿童各21名,以序列图片的方式呈现从动画片中截取的不同效价的情景事件,外显任务要求被试直接判断事件主角的情绪、内隐任务要求被试判断事件的一致性。结果发现：1.在外显任务中,自闭症儿童对正性和负性情绪的判断正确率均显著不如正常儿童,尤其是在负性情绪上存在明显的理解缺陷;2.在内隐任务中,正常儿童的正性负性情绪、自闭症儿童的正性情绪都表现出更弱的相对于中性情绪的理解效应;自闭症儿童的负性情绪理解则在两种任务中都接近于无。这些结果意味着自闭症儿童在外显和内隐任务中都存在负性情绪理解缺陷。     

Cognitive empathy moderates the relationship between affective empathy and wellbeing in adolescents with autism spectrum disorder

Background: Individuals with autism spectrum disorder (ASD) reportedly have reduced cognitive empathy (CE), yet intact levels of affective empathy (AE) when compared to typically developing individuals. To date, no research has examined the implications of this empathic imbalance on personal wellbeing (PWB). Method: Twenty four high-functioning adolescents with ASD (M _age = 13.21, SD = 2.83, 14 males) and 24 non-clinical control adolescents (M _age = 13.10, SD = 2.73, 15 males) took part in the present study. CE and AE were measured using the interpersonal reactivity index, while PWB was assessed via the personal wellbeing index-school children. Results: Participants in the ASD group scored significantly lower than the control group on measures of CE and AE. Moderated regression analyses revealed that for the ASD group only, CE appeared to moderate the relationship between AE and PWB. Specifically, when CE was low, the relationship between AE and PWB was significant and negative. However, when CE was high, the relationship between AE and PWB was significant and positive. Conclusions: CE appears central to the PWB of those with ASD. Only when CE is high were participants able to experience the positive relationship between AE and PWB. Interventions that target the cognitive dimensions of empathy may improve PWB.
