The paper presents a computational model showing repetition bias in human sequential decision-making, finding that choice frequency influences decisions alongside reward seeking.

This study identifies context-dependent repetition as a driver of decision biases and demonstrates a computational model based on reward learning and decision repetition that outperforms existing models.

The paper investigates how goal-directed and habitual control interact under time pressure, finding that habitual control adapts contextually through proactive and reactive mechanisms.

This study shows that chronic deep brain stimulation of the nucleus accumbens disrupts long-term stability of inter-temporal preferences in OCD patients.

This study investigates dopamine's role in human reinforcement learning using pharmacological interventions and fMRI, finding reduced decision thresholds under dopaminergic manipulations.

This study examines the effects of virtual gambling environments on problem gamblers and controls, finding increased physiological arousal but no substantial behavioral or physiological changes beyond craving.

This study investigates temporal discounting in adolescents and adults with Tourette syndrome, finding reduced impulsive choice in adolescents but no differences in adults.

This study uses a diffusion model to analyze how haloperidol affects temporal discounting and decision-making in humans, finding reduced discounting and faster response times.
