Learning the Phonological Forms of New Words: Effects of Orthographic and Auditory Input

We investigated the relationship between the phonological and orthographic representations of new words for adult learners. Three groups of native English speakers learned a set of auditorily-presented pseudowords along with pictures indicating their “meanings”. They were later tested on their memory of the words via an auditory word—picture matching test. While all three groups of participants heard the same auditory stimuli and saw the same pictures, the groups differed with respect to the written stimuli that accompanied each item during training. Some participants were presented with written forms for the auditory labels that were consistent with English spelling conventions (e.g., spelled form <kamad>, auditory form [k m d]), while others saw written forms that were not consistent with English spelling conventions (e.g., spelled form <kamand>, auditory form [k m d]), and a third group of participants was presented with no written forms. Participants who saw written forms that were not consistent with English spelling conventions showed interference from the words’ spelled forms at test. This finding provides evidence for a relationship between orthographic and phonological representations for newly-learned words.
