Automatic processes in word perception: an analysis from illusory conjunctions.
When asked to report the color of a target letter in a briefly presented word or pseudoword, Ss were more likely to report the color of letters from the same syllablelike unit than the color of other letters. Because Ss were not required to make a lexical decision or naming response, the multiletter units that are revealed by this task arise automatically. It was found that the syllablelike units are not phonological but correspond to orthographic patterns and morphemes. These units affect performance regardless of changes in letter-case, suggesting that the units are based on abstract letter identities. Unit formation was also not affected by visual field of presentation. Several experiments demonstrated that the morphological and orthographic units arise from different processes: The morphological units depend on lexical access, and the orthographic units do not. Finally, the effects of orthography are stronger for good readers than for poor readers.
