ADAPTIVE ATTENDING BEHAVIOR--MENTALLY RETARDED CHILDREN

这项提案正在寻求对一项研究计划的持续支持 智障与非智障的关系学习 个人，它已经由NICHD资助了3年。具体目标 当前研究者的主要任务就是分析和提升关系 刺激阵列的特性，以促进在 诸如奇特和样本匹配之类的任务。无论是弱智还是年轻人 非智障儿童在这些关系问题上尤其容易失败 任务(Green等人，1990；Soraci，Deckner，Baumeister和Carlin，1990)。 来自各种研究的综合证据表明，一个关键因素 智障儿童和非智障儿童之间的成绩差异是 对关系信息的差异敏感性。我们现在在 一般关系理论发展的形成阶段 这将对理解行星运动的轨迹产生影响 不同智力功能水平的表现差异 (例如，Soraci，Baumeister，和Carlin，在印刷中)。在拟议的研究中， 重点将放在视觉数组的结构在 促进相关刺激关系的检测，将其作为“前端” (Brown，Collins，&Dguid，1989)干预策略。建议数 研究分为两个部分：(A)全球刺激阵列 组织：怪异范式，以及(B)刺激特定组织： “侦查范式”。

This proposal is seeking continued support for a program of research involving relational learning in mentally retarded and nonretarded individuals, which has been funded by NICHD for 3 years. The specific aim of the present investigators is to analyze and enhance the relational characteristics of stimulus arrays in order to facilitate performance on tasks such as oddity and match-to-sample. Both mentally retarded and young nonretarded children are particularly prone to failure on these relational tasks (Green et al., 1990; Soraci, Deckner, Baumeister, & Carlin, 1990). Converging evidence from various studies suggests that a critical factor in the performance discrepancies between retarded and nonretarded children is a differential sensitivity to relational information. We are in the formative stages in the development of a general theory of relational learning that would have implications for an understanding of the locus of performance differences across varying levels of intellectual functioning (e.g., Soraci, Baumeister, & Carlin, in press). In the proposed studies, emphasis will be placed on the role of the structures of visual arrays in facilitating detection of relevant stimulus relations as a "front-end" (Brown, Collins, & Deguid, 1989) intervention strategy. The proposed studies are divided into two sections: (a) Global Stimulus Array Organization: The Oddity Paradigm, and (b) Stimulus-Specific Organization: The Detection Paradigm.
