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。 智力迟钝者和非智力迟钝者的关系学习 该项目已由NICHD资助三年。 具体目标 目前的研究人员的目的是分析和加强关系， 刺激阵列的特性，以促进性能 例如古怪和样本匹配等任务。 既有弱智又年轻 非弱智儿童特别容易在这些关系上失败， 任务（绿色等人，1990; Soraci，Deckner，Baumeister，& Carlin，1990）. 来自各种研究的证据表明， 弱智儿童和非弱智儿童之间的表现差异 对关系信息的敏感度不同。 我们正在 一般关系理论发展的形成阶段 学习，这将对理解的轨迹， 不同智力功能水平的表现差异 (e.g., Soraci，Baumeister，& Carlin，in press）. 在拟议的研究中， 重点将放在视觉阵列的结构的作用， 促进作为“前端”的相关刺激关系的检测 （Brown，柯林斯，& Deguid，1989）干预策略。 拟议 研究分为两个部分：（a）全球刺激阵列 组织：古怪范式，和（B）刺激特定组织： 检测范式。

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.
