Misperception of Orthographic Neighbors During Silent and Oral Reading

The study examined whether words are misperceived during natural fluent reading and the extent to which contextual and lexical properties bias perception. Target words were pairs of orthographic neighbors that differed in frequency. Pretarget context was neutral (Experiment 1) or biased toward the higher frequency member of the pair (Experiments 2 and 3), and posttarget context was neutral, congruent, or incongruent. Critically, incongruent context was constructed so that it was congruent with the target's neighbor. First-pass viewing showed only effects of target frequency. During silent reading (Experiments 1 and 2), rereading measures showed that the target frequency effect was smaller in the incongruent posttarget context condition than in the neutral and congruent conditions, and this occurred irrespective of prior context. Presumably, lower frequency words were less impeded by incongruent context because they were often misperceived as a congruent higher frequency neighbor. An oral reading task (Experiment 3) showed that the lower frequency target was more often misread than the higher frequency neighbor, and this proneness to error was influenced by posttarget context. Although target frequency influenced proneness to error, biased prior sentence context appeared to influence the construal of sentence meaning to accommodate incongruent targets and posttarget context.
