Snip, Nadia N. (2019) Transience and Facilitative Effects of Phonemic Codes in Cued Recall Tasks. Honours thesis, University of Southern Queensland. (Unpublished)
Abstract
Phonological information can have disruptive effects on Short Term Memory (STM). These effects have been shown to be short lasting. Emerging evidence shows phonemic information can also have facilitative effects when distributed phonological codes appear via irrelevant speech. However, these facilitative effects are indirect as they have not been compared to a control. Consequently, it is unknown if phonemic information is truly facilitative. It is also unknown if facilitative effects occur when phonemic information is presented visually. Likewise, the transience of distributed phonemic codes has not been tested. Thus, this study investigated the transience and facilitative effects of distributed phonemic codes in a visually presented cued recall task. A convenience sample of (N = 42) participated in study. Half of subjects were allocated to an immediate recall condition and half to a four second delayed recall condition. A 3 x 2 mixed design ANOVA revealed phonemic information has facilitative effects and that these effects generalise from items in an auditory stream to filler items in a cued recall task list. Conversely, distributed phonemic codes were not found to be transient. The latter could indicate that distributed phonemic information is not transient or may be due to methodological weaknesses such as cueing effects. The results have implications for the limited capacity store model of STM and for Tehan and Humphreys (1995) theory that transient phonemic information is responsible for proactive interference. Explanations for the results and suggestions for future research are provided.
