Abstract
Empirical data indicates that phonological coding can have a disruptive, transient effect on short-term memory recall. While there is mounting evidence that facilitative effects occur when phonologically similar words are distributed using irrelevant speech, these results are inconclusive as they have not yet been contrasted with a control condition. The present study addresses this gap in knowledge by investigating target recall can be primed as effectively as foil recall. It also investigates the transience of facilitative and disruptive phonological codes using a cued recall task. A convenience sample of 48 participants was recruited, and these participants were divided equally between two groups: an immediate condition or 1-second delayed retention interval condition. Using a 2x3 repeated measures mixed ANOVA, it was revealed that facilitative effects were not as effective as disruptive effects during a cued recall task. Phonemic codes did not have a facilitative effect on recall, which was unexpected, and potential reasons for this result were provided. Transience was not present for both facilitative and disruptive phonological coding, however this result was anticipated as it has been previously empirically asserted that transience occurs after a 2-second delay. The results support the embedded processes model asserted by Cowan (2001). It is suggested that future research investigates transience using multiple retention intervals in order to effectively locate the exact instance of its occurrence. Other future research has been suggested due to the identified methodological shortcomings.
