Effort-Based Decision-Making and Gross Motor Performance: Are They Linked?

Area of Science:

• Cognitive Neuroscience
• Motor Control
• Decision Science

Background:

• Effort-based decision-making is crucial for goal-directed behavior.
• Gross motor skills are fundamental for daily activities.
• Understanding the interplay between cognitive effort and motor performance is vital for both healthy individuals and clinical populations.

Purpose of the Study:

• To investigate the relationship between effort-based decision making and gross motor performance.
• To determine if willingness to expend cognitive effort correlates with motor task execution.
• To explore potential cognitive underpinnings of motor control.

Main Methods:

• Effort-based decision making was assessed using a modified Effort Expenditure for Rewards Task (EEfRT).
• Gross motor performance was measured via a walking task synchronized to an audio metronome at varying paces.
• Participants' button presses on a keyboard determined monetary rewards based on effort expended.

Main Results:

• No statistically significant relationship was found between effort-based decision making (EEfRT performance) and gross motor performance (walking task).
• The hypothesis that increased effort would correlate with increased steps per minute was not supported.
• Individual differences in effort expenditure did not predict motor performance metrics.

Conclusions:

• The study suggests that cognitive planning, rather than effort-based decision making, may be the primary cognitive factor influencing gross motor performance.
• Findings indicate a dissociation between the cognitive processes governing effortful choices and those controlling motor execution.
• These results have implications for designing interventions targeting motor deficits and for a broader understanding of cognitive-motor integration.
