The Use of Evoked Response Procedures in Studies of Reading Disability

Part of the The Downstate Series of Research in Psychiatry and Psychology book series (DSRPP, volume 2)


This paper defines the concept of specific reading disability, discusses its genetic and neurologic bases, and examines the re sults of eight evoked response studies which have appeared in the literature. While testing and analysis procedures vary in these reports, there is some evidence to suggest that evoked potential differences between normal and disabled readers may exist, particularly when recordings are made from parietal areas, and when linguistic stimuli are used. The suggestion is offered that the heterogeneity of the disorder may tend to obscure differences between normal and disabled readers when comparisons are made between group means. An approach employing the genetic method as used in the study of inherited conditions in families may help to isolate different subtypes of the disorder. This approach initially requires the establishment of the range and limits of normal response. Some data exploring laterality effects in normal readers using linguistic stimuli are presented and discussed in terms of this approach.
