关于阅读障碍儿童的听觉注意技能，多年来一直存在争议。数据表明，阅读障碍学生群体的注意力技能高度发达，但在同等群体中，注意力转移减少的情况也有记录。在强迫或定向注意的情况下，二分听力中的注意转移通常是从注意任务和耳朵之间的显著相互作用中推断出来的。然而，这一程序不能用来评估单独的测试表现，交互作用也不能给出一种有用的衡量二分听力中注意力转移的方法，这对与其他注意力测试相比有意义。本文使用注意力转移指数(ASI)来量化二分听力中的注意力转移，ASI是一种评估个体注意力转移程度的指标。ASI基于受试者在定向或强迫注意条件下进行测试时命中和入侵错误的对数赔率比。当58.3%的正常样本表现出显著的注意转移时，阅读障碍样本中没有一个表现出显著的注意转移。这一发现与不同类型的缺陷有关，这些缺陷可以解释缺乏听觉注意力转移的原因。(C)1998爱思唯尔科学有限公司。保留所有权利。
A controversy has existed for some years regarding auditory attentional skills in reading-disabled children. Data have suggested highly developed attentional skills in groups of reading-disabled students, but reduced attentional shifts have also been documented in equivalent groups. Attentional shifts in dichotic listening with forced or directed attention are usually inferred from a significant interaction between attentional task and ear. However, this procedure cannot be used to evaluate individual test performance, and the interaction does not give a useful measure of attentional shifts in dichotic listening meaningful for comparison with other tests of attention. In this paper attentional shifts in dichotic listening are quantified with the Attentional Shift Index (ASI), a measure for evaluating the degree of attentional shift in individual subjects. The ASI is based on the log-odds ratio of hits and intrusion errors when the subject has been tested under conditions of directed or forced attention. When 58.3% of the normative sample showed significant attentional shifts, none of the reading-disabled sample did so. This finding is discussed in relation to different types of deficits that can account for for the lack of auditory attentional shifts. (C) 1998 Elsevier Science Ltd. All rights reserved.
