Assessment of Perceptual, Decoding, and Lexical Skills and Their Relation to Reading Proficiency

Part of the Nato Conference Series book series (NATOCS, volume 5)


A central problem in evaluation research is the assessment of effects of instructional strategies on specific information processing skills. The goal of the research project on which I shall report is to develop and validate techniques for measuring perceptual and cognitive skills that are related to reading proficiency, and to investigate how deficiencies in particular skills may limit an individual’s ability to read with speed and comprehension. The measures to be developed are chosen to represent five skill domains or levels of processing, as illustrated in Figure 1.
