An important question in research on eye movements in reading is whether word frequency and word predictability have additive or interactive effects on fixation durations. A fair number of studies have reported only additive effects of the frequency and predictability of a target word on reading times on that word, failing to show significant…

Eye movements were monitored as subjects read sentences containing high- or low-predictable target words. The extent to which target words were predictable from prior context was varied: Half of the target words were predictable, and the other half were unpredictable. In addition, the length of the target word varied: The target words were short…

A second interim report on a reading program for Mexican-American children in an East Los Angeles elementary school notes that reading ability in the primary grades has improved. In January, 1967, the average first grade reading score on the Stanford Reading Test was at the third percentile, whereas in January, 1968, the score was at the eighth…
