The effect of phonemic repetition on syntactic ambiguity resolution: implications for models of working memory.

Two reading experiments investigated the extent to which the presence of phonemic repetition in sentences influenced processing difficulty during syntactic ambiguity resolution In both experiments, participants read sentences silently as reading time was measured Reading time on sentences containing a temporary syntactic ambiguity was compared to reading time on unambiguous control sentences. Sentences either did or did not contain repeated phonemes. The results showed that reading time was longer for sentences containing a syntactic ambiguity than for unambiguous control sentences. Reading time was also longer on sentences containing repeated phonemes than on sentences that did not contain repeated phonemes. Phonemic repetition did not increase the time taken for syntactic ambiguity resolution; rather, the effects of syntactic ambiguity and phonemic repetition were temporally distinct, with the effect of phonemic repetition following the effect of syntactic ambiguity. Implications for theories of working memory are discussed.
