Motor implementation of control and reward-based urgency regulation across impulsivity

The paper investigates how control-driven and reward-driven urgency regulation differ in individuals with varying impulsivity using motor system measurements.

Task goals shape the relationship between decision and movement speed

The paper investigates how task goals influence the relationship between decision and movement speed, finding that coregulation occurs as a default but is replaced by a tradeoff when detrimental to reward rate.

Movement characteristics impact decision-making and vice versa

The paper shows that decision-making and movement speed influence each other in a sensorimotor task, with faster movements affecting decision strategies similarly to faster decisions.

Post-error slowing reflects the joint impact of adaptive and maladaptive processes during decision making

The paper investigates how post-error slowing varies based on speed-accuracy tradeoff policies in different contexts and finds that it is only adaptive in a hasty context.

Challenging the function of motor inhibition: Does it really assist action selection?

This study investigates whether preparatory inhibition aids action selection by comparing MEP suppression in choice and simple RT tasks.
