Sensorimotor mechanisms in music performance: actions that go partially wrong

Area of Science:

• Cognitive Psychology
• Music Cognition
• Motor Control

Background:

• Musicians occasionally make errors during performance.
• Overtly correct responses can mask underlying error detection processes.
• Partial errors (e.g., incorrect force/duration) offer insights into online error monitoring.

Purpose of the Study:

• To compare pianists' production of correct pitches, pitch errors, and partial errors.
• To examine pre-error events and their relationship to subsequent errors.
• To investigate the role of response competition in error production.

Main Methods:

• Analysis of pianists' performance data, focusing on correct pitches, pitch errors, and partial errors.
• Examination of motor execution parameters (duration, intensity) preceding errors.
• Comparison of kinematic and acoustic features of correct vs. erroneous events.

Main Results:

• Errors were produced with slower durations and softer intensities compared to correct events.
• Pre-error events exhibited intermediate durations and intensities, suggesting response competition.
• Partial errors were linked to response competition with upcoming erroneous sequences.

Conclusions:

• Findings support cascade models of sequence production, where partial information guides ongoing responses.
• Partial error behavior indicates online error detection and response adjustment.
• Motor control mechanisms play a crucial role in error monitoring and correction during musical performance.
