In order to understand the process of reading, it is important to determine how strings of letters are perceived. This study tests the hypothesis that units of visual perception may include pairs of letters and perhaps even high-frequency, monosyllabic trigrams (three-letter sequences). Participants were asked to report the names of either single…

This study with 47 university students having reading disabilities, 15 students with other learning disabilities, and 12 nondisabled readers found that most nondisabled subjects used a phonological rehearsal strategy for words and nonwords, whereas students with reading disabilities consistently used a strategy of visual scanning for these tasks.…

A discrete color naming paradigm was used in two experiments examining activation along orthographic and phonological dimensions in visual and auditory word recognition. Subjects were 80 college students who were presented with a prime word, either auditorally or visually, followed 200 milliseconds later by a target word printed in a color. The…

Examined age differences in the missing-letter effect during letter-detection tasks. Found expected increase in magnitude with age of the effect even when function words and content words were equated for frequency. Word scrambling improved letter detection in function words compared to content words among older subjects, arguing against increased…

The assumption that phonological processes support comprehension guided two experiments in manipulating the similarity of the consonant code both within silently read sentences and between these sentences and concurrently vocalized phrases. The first experiment examined whether tongue-twisters would take longer to read than phonetically…
