We report data from an experiment where participants performed immediate serial recall of visually presented words with or without articulatory suppression while also performing homophone or rhyme detection. The separation between homophonous or rhyming pairs in the list was varied. According to the Working Memory model (Baddeley & Hitch, 1974; Baddeley, 1986), suppression should prevent articulatory recoding. Nevertheless, rhyme and homophone detection was well above chance. However, with suppression, participants showed a greater tendency to false-alarm to orthographically related foils (e.g. GIVE-FIVE). This pattern is similar to that observed in short-term memory patients.
