自闭症幼儿的视觉性自我认知实验研究

通过对平均心理年龄为23个月的6名自闭症幼儿的实验研究．甄别他们是否能从视觉上进行自我与他人的分化认知并进一步探索自闭症幼儿对镜像自我认知与录像自我认知上的差异;以秒为单位．对实验结果和过程进行了编码分析。结果表明：这6名幼儿在看自己的录像时,比看同伴的表现出更多的关注和喜悦;对录像的自我进行认知寸表现出更大的关注和积极情绪。由此推断他们已具有初步的自我认知。     

ELEVATION OF VOICE VOLUME IN YOUNG DEVELOPMENT ALLY DELAYED CHILDREN VIA AN OPERANT SHAPING PROCEDURE

Unusually low voice volume was identified by teachers as a significant impediment to the academic and social progress of two preschool students. A simple operant shaping procedure was conducted by teachers to increase voice volume using a voice-activated apparatus with attractive visual display. Setting generalization of volume increases to the classroom was achieved and maintained at one- and four-month follow-ups.     

Effects of video modeling on social initiations by children with autism

We examined the effects of a video modeling intervention on social initiation and play behaviors with 3 children with autism using a multiple baseline across subjects design. Each child watched a videotape showing a typically developing peer, and the experimenter engaged in a simple social interactive play using one toy. For all children, social initiation and reciprocal play skills were enhanced, and these effects were maintained at 1- and 3-month follow-up periods.     

Specificity of Learning in a Video-Aiming Task: Modifying the Salience of Dynamic Visual Cues

The authors investigated whether the salience of dynamic visual information in a video-aiming task mediates the specificity of practice. Thirty participants practiced video-aiming movements in a full-vision, a weak-vision, or a target-only condition before being transferred to the target-only condition without knowledge of results. The full- and weak-vision conditions resulted in less endpoint bias and variability in acquisition than did the target-only condition. Going from acquisition to transfer resulted in a large increase in endpoint variability for the full-vision group but not for the weak-vision or target-only groups. Kinematic analysis revealed that weak dynamic visual cues do not mask the processing of other sources of afferent information; unlike strong visual cues, weak visual cues help individuals calibrate less salient sources of afferent information, such as proprioception.     

IN VIVO LANGUAGE INTERVENTION: UNANTICIPATED GENERAL EFFECTS

After observing the lack of generalization of language trained in highly structured training sessions using established behavior modification techniques, “incidental teaching” procedures were developed to change the use of specified language behaviors in the natural environment. This paper reports an analysis of the general changes in the language, other than that specifically targeted by the incidental teaching procedures, used by disadvantaged preschool children. The daily language samples of disadvantaged children involved in a previously reported experiment to increase compound sentence usage were reexamined and compared to comparable records of other disadvantaged children and of middle-class children of college parents in order to assess possible general effects of the intervention program. Whereas the language that both groups of comparison children used changed little across the preschool year, the amount of talking by the children in the experimental program increased markedly. Their use of more elaborate vocabulary and more elaborate sentences also increased in direct proportion to the increases in overall language use, such that both language use and language elaboration in the experimental group of children changed from a pattern similar to the comparison group of disadvantaged children to a pattern similar to the comparison group of middle-class children. It is argued that some general features of the incidental teaching procedure—differentially attending to child overtures and responding relative to the child's selected topic (reinforcer)—contributed to the increase in overall language use beyond the specific language behavior targeted, and that this increase in the probability of children's talking itself resulted in the substantial increases in elaboration seen in the children's spontaneous language. Because, at least in children with fairly well-developed language repertoires, language use is contextually controlled, talking more involves talking in more varied and complex contexts, which inevitably produces the use of more elaborate language.     

Using a Session Feedback Form in Cognitive Therapy with Children

This article presents a new written form for eliciting session feedback from children. The importance of session feedback is discussed and the specific written form is presented. Clinical applications and advantages of the session feedback form are also reviewed. Additionally, the uses of the session feedback form in supervision are explained. Finally, cautions and limitations are outlined.     

3～6岁儿童对言语行为的元认知发展

以123名3~6岁儿童为被试,采用图片判断和个别访谈任务,从本体区分和归因的角度,对3~6岁儿童对言语行为的元认知发展进行了探查。结果表明:3~6岁儿童对言语行为和物理发音区分较早,但对于言语行为和生物发音的区分水平普遍较低;34、岁儿童对语言习得的遗传因素认知水平较低,5岁开始发展,6岁有显著提高;3~6岁儿童对语言习得的环境因素认知水平都较低。     

3～6岁幼儿对攻击性行为的认知评价分析

通过故事评定法分析了3～6岁幼儿对攻击性行为的认知评价,结果表明:①此年龄段的幼儿对攻击性行为的认知已经达到一定的成熟度,开始考虑攻击性行为的条件与方式;②幼儿对攻击性行为的认知评价存在一定的性别差异,主要表现在受到言语侵犯时的攻击性行为;③对攻击性行为的认知评价的年龄差异突出表现在5岁与6岁之间.④采用蒙特梭利教育法的实验班幼儿,对攻击性行为比非实验班幼儿评价得更消极.
