Using a combination of letter-detection and proofreading techniques, subjects searching for target letters in printed text made more errors on correctly spelled words than misspelled words. This word inferiority effect contrasts with the superior perception of letters in words over nonwords commonly found in tachistoscopic studies. (Author/CM)

In three experiments, subjects read passages and circled misspelling in them. Results support the unitization hypothesis that common words are normally read in units larger than letters but are read in letter units when misspelled. (Author/CP)

Subjects instructed to circle misspellings while reading prose were less likely to detect misspellings in function than in content words. Misspellings that changed the shape of a word were more likely to be detected. It is not clear whether differences between function and content words are due to familiarity or redundancy. (Author/RD)
