The production of a disyllabic word is speeded up by advance (off-line) knowledge of the first syllable, but not by knowledge about the second syllable (Meyer, 1990). By contrast, when first-syllable or second-syllable primes are presented during the production of a disyllabic word (on-line), both primes yield a facilitatory effect (Meyer & Schriefers, 1991). In this paper, the computational model of word-form encoding in speaking developed in Roelofs (1992b, submitted) is applied to these contradictory findings. Central to the model is the proposal by Levelt (1992) that morphemic representations are mapped onto stored syllable programs by serially grouping the morphemes' segments into phonological syllables, which are then used to address the programs in a syllabary. Results of computer simulations reported in this paper show that the model resolves the empirical discrepancy.
