Phonological recoding for reading: the effect of concurrent articulation in a Stroop task.

The present experiment obtained Stroop and reverse Stroop effects in a card-sorting task where subjects were required to sort cards into bins, labelled with either colour patches or colour names in black ink, under silent and concurrent articulation conditions. Performance by normal subjects and a conduction aphasic supported the notion that concurrent articulation affects post-lexical phonology. It was shown that the status of the hypothesis that pre-lexical phonology is normally used to access meaning during reading (the speech recoding hypothesis) remained uncertain if concurrent articulation only affected post-lexical phonology.
