Evidence for Enhanced Interoceptive Accuracy in Professional Musicians

Area of Science:

• Neuroscience
• Psychology
• Auditory Perception

Background:

• Interoception, the perception of internal bodily signals, is generally stable but can be modulated by learning.
• Music-making is a complex multisensory activity known to alter neural representations in musicians.
• Previous research indicates music training impacts sensory and motor functions, but its effect on interoception is less understood.

Purpose of the Study:

• To investigate whether musical training enhances interoceptive accuracy.
• To compare interoceptive accuracy between professional musicians (singers, string players) and non-musicians.
• To explore the relationship between musical practice, dispositional traits, and interoceptive performance.

Main Methods:

• Utilized a heartbeat discrimination task to assess interoceptive accuracy.
• Compared interoceptive performance in professional singers, string players, and matched non-musicians.
• Administered psychometric measures for dispositional traits and performance anxiety.

Main Results:

• Musicians (singers and string players) exhibited significantly higher interoceptive accuracy than non-musicians.
• No significant difference in interoceptive accuracy was found between singers and string players.
• Musical practice duration correlated with interoceptive accuracy in singers, but not string players.
• Dispositional traits did not confound the observed differences in heartbeat discrimination.

Conclusions:

• Professional musicians demonstrate enhanced interoceptive accuracy compared to non-musicians.
• Musical training is a likely factor contributing to heightened interoception.
• These findings suggest that engaging in complex multisensory activities like music can refine the perception of internal bodily states.
