This study examines how monetary reward affects motor control in younger and older adults, finding age-related differences in movement vigour but not in action selection.

The paper investigates how kinematic fusion affects sequence planning in a handwriting-like task, finding that movement elements remain competitively pre-ordered regardless of fusion, supporting competitive queuing rather than neural fusion.

This study shows dopamine affects movement speed, speed-modulation, and speed-meta-modulation through two pharmacological interventions in Parkinson's patients and healthy individuals.

This study investigates how sequence learning affects bilateral intracortical inhibition during motor preparation, finding that it alters baseline inhibition levels rather than the acute inhibition decreases during preparation.

This study investigates how rewards and punishments affect motor performance by examining changes in glutamatergic facilitation and GABAA inhibition in the motor cortex during movement preparation.

This study shows that dopamine antagonists impair reward-based motor vigour but not movement fusion during sequential reaching tasks.

This study investigates how reward affects seven sensorimotor feedback loops in humans, finding that faster loops are insensitive to reward while slower loops show latency reductions.

This study investigates how explicit reward and performance feedback differentially affect sequential motor behavior, showing that their combination maximizes performance gains and leads to long-lasting improvements.

The paper presents a framework to assess VR hand-tracking accuracy, finding average positional error of 1.1cm, joint angle error of 9.6°, and delay of 38ms for the Oculus Quest 2.

This study compares how reward affects motor performance in young and older adults during sequential reaching tasks, finding reward improves performance in both groups.

This study shows that reward improves sequential reaching performance, with gains maintained after reward removal, suggesting coarticulation enhances efficiency and retention of motor improvements.

The paper investigates how reward affects motor control by disrupting brain areas involved in reward processing and motor control, finding that transcranial magnetic stimulation did not alter reward-driven improvements in movement.

This study shows reward improves motor performance by enhancing feedback control and reducing motor noise through increased arm stiffness.

This study shows that working memory capacity, not dopamine-related genetics, predicts success in reward-based motor learning tasks.

The paper investigates age-related changes in motor decision-making by examining the role of Pavlovian biases in reward and punishment sensitivity across a large sample.

This study investigates how explicit strategies influence reward-based motor learning, finding that strategy use is critical for successful learning and that its disruption impairs learning.

This study investigates how reinforcement and explicit strategies interact during visuomotor adaptation, finding that strategy-use is critical for reinforcement-based learning.

This study shows reward and punishment enhance motor adaptation and retention in stroke patients, similar to healthy controls.
