Does bimanual coordination training benefit inhibitory function in older adults?

Area of Science:

• Neuroscience
• Motor Control
• Cognitive Psychology

Background:

• The impact of complex movement training on cognitive functions, particularly inhibition, remains unclear.
• Investigating transfer effects to untrained tasks is crucial for understanding underlying mechanisms.

Purpose of the Study:

• To determine if bimanual coordination training improves inhibitory functions.
• To assess if these improvements transfer to non-practiced motor and cognitive tasks.

Main Methods:

• 17 older adults trained in bimanual anti-phase coordination while inhibiting in-phase patterns.
• Tested transfer effects on untrained bimanual coordination and cognitive tasks (Stroop, MAPIT) measuring reaction time and errors.
• Utilized ANOVAs and mediation analyses to evaluate training effectiveness and transfer mechanisms.

Main Results:

• Bimanual coordination training improved performance on the trained task and delayed spontaneous transitions.
• Training benefits transferred to untrained bimanual coordination and cognitive tasks involving inhibition.
• Mediation analyses confirmed that enhanced inhibitory functions drove the transfer of training.

Conclusions:

• Bimanual coordination practice effectively enhances inhibitory control.
• Training-induced improvements in inhibition transfer to diverse motor and cognitive tasks, indicating shared neural processes.
