Phonological inhibition in written production

The present study investigated the contribution of phonological relatedness on written production using the blocked cyclic naming paradigm. Participants were instructed to write down picture names in homogeneous and heterogeneous context. In the homogeneous context, items shared a syllable which corresponded to different written forms in various items. The position type of the shared syllable was manipulated so that the shared syllable was initial-only or distributed across various positions of words. Contrary to previous studies which showed facilitative effects of phonological relatedness on written production, interference effects in both reaction times and errors were found for both position types of phonological overlap. The findings indicate that phonological overlap does not always lead to facilitation but inhibition could occur. Implications of the present findings for theoretical models of word production are discussed.
