Individual Differences in Dopaminergic Modulation of Exploration-Exploitation Behaviour

This study investigates how dopamine levels affect exploration-exploitation behavior in humans, finding that cognitive capacity and sex moderate L-DOPA effects on decision-making.

Catecholamine Precursor Modulation of Human Exploration:Evidence From a Large Gender-Balanced Sample

This study shows that Tyrosine supplementation improves reinforcement learning by stabilizing choice behavior and increasing value-driven exploitation in a gender-balanced sample.

Dopamine and temporal discounting: revisiting pharmacology and individual differences

The paper re-examines the pharmacological effects of L-DOPA on temporal discounting in a large sample and evaluates proxy measures for dopamine, finding a reliable reduction in discount rate with no credible effects from proxy measures.

Ambulatory physiological measures obtained under naturalistic urban mobility conditions have acceptable reliability

This study assesses the reliability of ambulatory physiological measures during urban walking, finding acceptable test-retest reliability for compound scores derived from cardiovascular and electrodermal activity.

Reduced Model-Based Control in Gambling Disorder Despite Intact Neural Value and Task Structure Representations

This study investigates reduced model-based control in gambling disorder using reinforcement learning tasks, computational modeling, and fMRI, finding intact neural representations of task structure despite behavioral impairments.

Pharmacological enhancement of dopamine neurotransmission does not affect illusory pattern perception

This study investigates whether dopamine manipulation affects illusory pattern perception in healthy individuals, finding no significant effect of L-DOPA on false alarm rates or other measures.

Erotic cue exposure increases physiological arousal, biases choices towards immediate rewards and attenuates model-based reinforcement learning

The paper examines how erotic cues affect physiological arousal, reward discounting, and model-based reinforcement learning in healthy males.

Appetitive cue exposure increases neural reward responses without modulating temporal discounting

The paper examines how exposure to appetitive cues affects temporal discounting and neural reward responses in humans, finding no significant effect on discounting despite increased neural activity.

Trial-wise exposure to visual appetitive cues increases physiological arousal but not temporal discounting.

The paper tests how exposure to appetitive, aversive, and neutral visual cues affects temporal discounting and physiological arousal in humans, finding no significant increase in discounting despite increased arousal.
