Dopaminergic manipulations affect the modulation and meta-modulation of movement speed: evidence from two pharmacological interventions

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

Dopamine challenge reduces mental state attribution accuracy

This study shows that dopamine antagonists reduce accuracy in mental state attribution tasks in healthy volunteers, suggesting dopamine's causal role in Theory of Mind.

Autistic kinematics diverge from the power laws that typically govern movement

The paper finds that autistic adults exhibit steeper speed-curvature gradients and less precise speed oscillation modulation compared to non-autistic adults, suggesting deviations from typical movement power laws.

Dopaminergic modulation of dynamic emotion perception

This study investigates how dopamine affects emotion recognition by testing haloperidol's effects on dynamic emotion perception, finding that outcomes depend on baseline dopamine levels.
