The effect of expertise on auditory categorization: A domain-specific or domain-general mechanism?

2018, Master of Arts, Ohio State University, Psychology.
Are the perceptual and cognitive changes associated with expertise due to improvements in domain-general abilities or changes to domain-specific representations? Elmer et al. (2014) measured how controls, language experts, and musicians categorized perceptually ambiguous sounds (blends of speech and music) and concluded domain-general changes underlie expertise. Acoustic and perceptual analyses of their stimuli suggested their stimulus creation methodology might have distorted the results. An experiment replicated and extended their findings with revised stimuli. Results of that experiment suggest that expertise leads to domain-specific changes in representational weighting or selective attention. However, in a generalization experiment designed to replicate these results and extend findings to new sounds, musicians and controls showed a consistent reversal in performance. Possible reasons for the inconsistency and suggestions to eliminate these problems are explored within.
