Do Musicians and Non-musicians Differ in Speech-on-Speech Processing?

Area of Science:

• Auditory Neuroscience
• Cognitive Psychology
• Speech Perception

Background:

• Previous research suggests musicians may outperform non-musicians in adverse listening conditions, particularly in speech-on-speech perception.
• However, existing literature presents conflicting findings regarding these auditory processing advantages.

Purpose of the Study:

• To investigate potential differences in speech-on-speech processing between musicians and non-musicians.
• To employ diverse measures of spoken language processing, including offline and online methods, to capture these differences.

Main Methods:

• Utilized an offline sentence recall task for speech perception.
• Employed online measures: gaze-tracking and pupillometry for real-time spoken language processing.
• Tested participants with comparable stimuli complexity across all tasks.

Main Results:

• Musicians demonstrated superior performance in the sentence recall task.
• Eye-tracking showed musicians exhibited reduced lexical competition with increasing masker levels.
• Pupil dilation data provided limited insights into cognitive resource differences between groups.

Conclusions:

• Eye-tracking suggests musicians may adopt distinct strategies for spoken word recognition in noise.
• Further research is needed to clarify whether observed differences stem from enhanced cognitive control or auditory processing in musicians.
