Effects of selective attention on syntax processing in music and language

Area of Science:

• Neuroscience
• Cognitive Science
• Psychoacoustics

Background:

• Syntactic processing in music and speech is crucial for comprehension.
• Event-related potentials (ERPs) offer insights into the neural dynamics of syntactic processing.
• The role of auditory selective attention in modulating these processes remains an active area of research.

Purpose of the Study:

• To investigate the impact of auditory selective attention on the neural processing of syntactic structures in music and speech.
• To determine whether shared neural resources exist for early syntactic processing in music and speech.

Main Methods:

• Event-related potentials (ERPs) were recorded while participants listened to speech and music stimuli.
• Stimuli were presented in isolation or simultaneously, with participants attending to either speech or music.
• Syntactic correctness of final words in sentences and final chords in musical sequences was manipulated.

Main Results:

• Irregular chords elicited an early right anterior negativity (ERAN), which was reduced when music was presented with attended speech.
• Irregular sentences elicited an early left anterior negativity (ELAN) irrespective of attention.
• No significant interaction of neural resources for syntactic processing was observed at these early stages.

Conclusions:

• Neural mechanisms for syntactic processing in music and speech appear to operate partially automatically.
• Auditory selective attention modulates music syntax processing but not speech syntax processing at early neural stages.
• Findings do not strongly support early interaction of neural resources for syntactic processing across music and speech.
