Eye movements of prereaders to pseudowords containing letters of high and low confusability

Children were required to make same-different judgments about matched and unmatched pseudoword pairs containing middle letters of either high confusability (e.g.. ZPR.W or low confusability (e.g., EROI). Differential eye-movement patterns were observed between matched and unmatched low-confusion pairs. This finding would be predicted from a features analysis of the visual characteristics of the letters of the pseudowords. Low-confusion pseudowords contain more different visual features than high-confusion pseudowords. Therefore, in making a matching judgment. low-confusion pairs should require more eye movements; however, detection of a mismatch should be facilitated due to the greater availability of distinctive features.
