Proactive interference and speech-in-noise recognition by listeners with normal hearing
2013 (English)Conference paper, Poster (Other academic)
Complex working memory capacity (WMC) span tasks have been shown to predict aided and unaided speech in noise recognition (see Akeroyd, 2008 for a review). Studies of complex WMC span tasks suggest that rather than indexing a single cognitive process, performance on such tasks may be governed by separate cognitive subprocesses embedded within WMC (see for example, Sörqvist, Ljungberg, & Ljung, 2010). Thus, the predictive relationship between scores on complex WMC span tasks and the perception of speech-in-noise may not due to WMC per se, but rather to one or more of the component processes that WMC tasks may index. Previous research has suggested that subprocesses may include executive functioning (Whitney et al., 2001) and resistance to proactive interference (Kane and Engle, 2000). Proactive interference (PI) refers to difficulties memorizing current information due to interference from previously stored long-term memory representations for similar information. Although PI is typically investigated in relation to semantic interference, the present research aims to examine PI caused by differences in phonological representations, similar to those caused by a hearing loss or different signal processing methods. The results of a study conducted to investigate the relationship between these cognitive processes and the speech in noise recognition scores of listeners with normal hearing will be presented.
