Relationship of Ocular Latency and Speed to Intellectual Performance

The purpose of this study was to investigate the relative effectiveness of specific media attributes (visual) on S performance on criterion tests measuring different levels of understanding. One hundred seventy-one Ss were assigned to one of three entering behavior groups (high, middle, and low) as a result of their performance on a pretest designed for this purpose. Ss participated in their respective presentations and received two criterion tests. Analyses indicated that (a) there was a significant relationship between entering behavior and performance on the criterion tests; (b) no significant relationship was found to exist between the level of stimulus explicitness and achievement on the criterion tests; and (c) no significant interactions were found to exist between entering behavior and type of visualization.
