ABSTRACTThis paper reports two experiments which use a micro‐computer driven self‐paced reading task to examine the reading strategies of good and poor readers. Unlike previous work using this technique the children were able to regress to earlier parts of the texts by pressing the appropriate computer key. The main focus of the experiments is on the relationship between reading strategies, reading ability and the length of the textual units which are presented to the children. Reading ability is found to influence reading strategies differently according to whether text is presented in single words or in phrases. A similar result is found for the time taken to read the texts. The results are discussed in the light of current theories of text processing. However the main point of the paper is to illustrate the use of a potentially powerful diagnostic tool which will operate on computers currently available in scho
