Autism as a Form of Life: Wittgenstein and the Psychological Coherence of Autism

Autism is often taken to be a specific kind of mind. The dominant neuro‐cognitivist approach explains this via static processing traits framed in terms of hyper‐systemising and hypo‐empathising. By contrast, Wittgenstein‐inspired commentators argue that the coherence of autism arises relationally, from intersubjective disruption that hinders access to a shared world of linguistic meaning. This paper argues that both camps are unduly reductionistic and conflict with emerging evidence, due in part to unjustifiably assuming a deficit‐based framing of autism. It then develops a new Wittgensteinian account—autism as a different form of life—which avoids these issues. Rather than autistic systemising being the basis of autistic cognition, it is taken to be a reaction to pre‐epistemic and semantic anxieties that come with developing as a minority within a different form of life. This re‐framing can provide a coherent account of the autistic mind, and has significant conceptual, practical, and ethical implications.     

自闭症谱系障碍者的视运动知觉

视运动知觉是人脑对外界物体的运动特性的知觉。视运动知觉异常是自闭症谱系障碍者的一种常见表现, 其检测光流、二阶运动、协同性运动、生物运动及运动速度的能力异于健康控制组, 且过度迷恋重复性运动物体。该群体视运动知觉异常的原因探析集中于背侧/M细胞通路特定假设、复杂性假设、神经噪声假设、经验缺失假设、时空加工异常假设、极端男性脑理论和社会脑假设。但到目前为止, 尚缺乏一个统一准确的、可验证的解释。未来研究应注重考察自闭症者视运动知觉异常的个体差异和神经生理机制, 进一步整合和验证解释理论, 并着眼开发有效的视运动知觉测评工具和干预策略     

RESPONSE-REINFORCER RELATIONSHIPS AND IMPROVED LEARNING IN AUTISTIC CHILDREN

In order to affect more rapid response acquisition for autistic children, researchers have recently begun to investigate the functional relationships of reinforcers to other components of the operant conditioning paradigm. Previous research suggested that functional relationships between target behaviors and reinforcers might be especially effective. For example, locating a reward inside a container might be a more efficient way to teach a child to open the container than by handing the child a reward for opening an empty container. The present experiment assessed, within a multiple baseline design, the possibility of improving autistic children's learning by changing arbitrary response-reinforcer relationships (while holding target behaviors and reinforcers constant) so that the target behaviors became functional (i.e., a direct part of the response chain required for the child to procure the reinforcer). The results showed that: (1) arranging functional response-reinforcer relationships produced immediate improvement in the children's learning, and resulted in rapid acquisition of criterion level responding; and (2) high levels of correct responding initially produced by functional response-reinforcer relationships were continued even when previously ineffective arbitrary response-reinforcer conditions were reinstated. The results are discussed in terms of understanding and improving autistic children's learning.     

Teaching generalization of purchasing skills across community settings to autistic youth using videotape modeling.

Three young autistic adults were trained to purchase items. Training was conducted in one setting with concurrent generalization probes taken in three community stores. Training in one setting failed to produce generalization to the three probe settings. Generalization training, which consisted of viewing videotapes of models who purchased items in the probe settings and answering questions about the models'' responses, was then introduced. Training with the videotapes resulted in generalization to the three community stores. Results of the use of videotapes as a cost-effective means to program generalization in community training programs are discussed.     

Generalization of parent-training results

Two experiments were conducted to assess the generalized effects of several different parent/teacher training programs. In Experiment I it was found that a brief demonstration of how to teach an autistic child new behaviors was sufficient to teach parents how to teach those children those behaviors. However, generalization to new child-target behaviors did not take place. Another parent training program, which did not demonstrate how to teach any one specific child behavior, but was based on teaching the use of general behavior-modification procedures, was effective in teaching the parents how to teach new child-target behaviors. Experiment II then provided analyses of the individual effects of several components of the generalized training program. The results showed that videotape illustrations of the procedures, without the presence of a master teacher, were sufficient to teach the adults. However, sub-parts of the videotapes produced highly specific training results, with each component changing corresponding areas of the adults' behaviors. Viewing of the entire package was necessary before the adults were able to improve the autistic children's behaviors. The study as a whole suggests the importance of obtaining multiple measures of the effects of parent and teacher training programs, including measures of acquisition and generalization of both adult and child behaviors.     

EFFECTS OF CHOICE MAKING ON THE SERIOUS PROBLEM BEHAVIORS OF STUDENTS WITH SEVERE HANDICAPS

This study assessed the impact of choice making on the serious problem behaviors of 3 students with severe autism and/or mental retardation. In the context of within-subject reversal designs, the results showed consistently reduced levels of problem behaviors (e.g., aggression) when the students were given opportunities to make choices among instructional tasks and reinforcers. Additional data showed no systematic differences in the rate of correct responding between the two conditions. The results are discussed in relation to the continuing search for effective, nonintrusive solutions to the occurrence of serious problem behavior.

PROBLEMS OF INTERNALIZATION: A BUTTON IS A BUTTON IS—NOT

Analysts hope to help the patient internalize a relationship with the analyst that contrasts with the original archaic object relation. In this paper, the author describes particular difficulties in working with a patient whose defenses and anxieties were bulimic, her movement toward internalization inevitably undone. Several issues are considered: how does the nonsymbolizing patient come to internalize the analyst's understanding, and when this does not hold, what is the nature of the patient's subsequent methods of dispersal? When the patient can maintain connection to the analyst as a good object, even fleetingly, in the depressive position, the possibility of internalization and symbolic communication is increased.     

特应性皮炎的发病机制

近年来关于特应性皮炎（AD）的发病机制研究进展迅速,目前研究认为AD发病主要是皮肤屏障功能障碍、免疫应答异常和环境因素刺激共同作用的结果。遗传学研究证实,皮肤屏障功能相关基因和免疫应答及其调控基因参与AD发病。皮肤屏障功能障碍是皮肤激发和维持AD炎症的重要原因。在皮肤屏障受损的基础上,外源过敏原和微生物就很容易透过角质层进入表皮和真皮,进而引发免疫应答。AD瘙痒的病理生理学机制还不清楚,除外组胺,其他的炎症介质和致痒原等也参与介导了瘙痒发生。

在事物发展的过程中,主要矛盾处于支配地位、对事物发展起决定作用,次要矛盾处于从属地位、对事物发展起次要作用.烧伤后应激性溃疡的发病机制如:神经-内分泌失调、胃黏膜屏障功能减弱、感染和心理应激等,以及防治方法,如:抗休克治疗、积极处理创面,改善胃黏膜缺血,早期肠内营养和防治感染等是这一原理的具体体现.
