Modulation of neurocognitive functions associated with action preparation and early stimulus processing by...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Human Motor Control

Background:

• Feedback on action correctness is crucial for learning.
• Limited research exists on the neural mechanisms of feedback processing and its impact on performance.
• Previous studies primarily focused on event-related potentials (ERPs) like the feedback-related negativity, occurring post-feedback.

Purpose of the Study:

• To investigate the neural effects of providing feedback on brain activity before and after stimulus presentation.
• To determine the impact of feedback on cognitive functions, including anticipatory and post-stimulus processing.
• To compare cognitive control and performance in a standard visuomotor task versus a modified version with error feedback.

Main Methods:

• Participants performed a standard visuomotor task.
• A modified version of the task incorporated auditory feedback cues for performance errors.
• Electroencephalography (EEG) was used to analyze brain activity, focusing on specific components modulated by feedback.

Main Results:

• Behavioral measures, including cognitive control, significantly improved in the feedback task compared to the standard task.
• All studied electroencephalography (EEG) components were modulated by the presence of feedback cues.
• Feedback led to increased anticipatory activity in the prefrontal cortex, reduced perceptual awareness linked to the anterior insular cortex, and enhanced selective attention in sensory cortices.

Conclusions:

• Providing error-related feedback enhances cognitive control and task performance.
• Feedback influences neural processes related to anticipation, perceptual awareness, and attention.
• This study highlights the significant impact of feedback timing and presence on cognitive functions and learning.
