Two divided visual Weld lexical decision experiments were conducted to examine the role of the cerebral hemispheres in transposed-letter similarity eVects. In Experiment 1, we created two types of nonwords: nonadjacent transposed-letter nonwords (TRADEGIA; the base word was TRAGEDIA, the Spanish for TRAGEDY) and two-letter diVerent nonwords (orthographic controls: TRATEPIA). In Experiment 2, the controls were one-letter diVerent nonwords (TRAGEPIA) instead of two-letter diVerent nonwords (TRATEPIA). The eVect of transposed-letter similarity was substantially greater in the right visual Weld (left hemisphere) than in the left visual Weld. Furthermore, nonwords created by transposing two letters were more competitive than the nonwords created by substituting one or two letters of a target word. We examine the implications of these Wndings for the models of visual word recognition.
