Neural dynamics underlying coordination between training-induced habitual and goal-directed responses

Area of Science:

• Neuroscience
• Cognitive Psychology
• Sports Science

Background:

• Coordinating habitual and goal-directed behaviors is crucial for preventing behavioral disorders.
• Inducing habitual responses in laboratory settings is challenging.
• Well-trained athletes offer insights into automatic perception-action associations.

Purpose of the Study:

• Investigate neurocognitive mechanisms of habitual vs. goal-directed behavior coordination in athletes.
• Examine how expertise-related stimuli influence behavior and brain activity.
• Dissociate automatic habitual responses from goal-directed inhibition control.

Main Methods:

• Recorded electroencephalograms (EEG) from athletes during a Simon task with expertise-related stimuli.
• Manipulated stimulus-response congruency to differentiate habitual and goal-directed processes.
• Analyzed behavioral data and EEG measures including lateralized readiness potentials and theta/beta band activity.

Main Results:

• Athletes displayed a stronger behavioral congruency effect for expertise-related stimuli compared to controls.
• EEG revealed enhanced response tendency (beta activity, lateralized readiness potentials) in athletes for congruent stimuli.
• Incongruent stimuli in athletes engaged response inhibition (theta activity).
• EEG markers correlated with performance efficiency.

Conclusions:

• Sports training enhances the coordination of habitual responses to expertise-related stimuli.
• This involves automatic response preparation and efficient response inhibition.
• Neurocognitive mechanisms underlying this enhanced coordination are revealed through EEG.
