This study examines how metacognitive experiences like boredom and frustration evolve over time during a task and relate to cognitive processes that optimize performance.

This paper analyzes fMRI neurofeedback data to identify brain regions and networks involved in feedback processing and regulation recalibration during training.

This study compares the physiological mechanisms of action cancellation and cancellation of action cancellation using EMG, finding no difference in cancellation speed between conditions.

This study finds older adults show increased locus coeruleus activity and connectivity with dorsolateral prefrontal cortex during ambiguous facial emotion recognition, linked to better mental well-being.

This study identifies a species-conserved mechanism of hypothesis testing in rats and humans during rule learning, which enhances cognitive flexibility in complex environments.

This study uses a Bayesian hierarchical model to decode decision-making properties from trust game data, identifying biomarkers linked to trusting behavior in MDD patients and healthy controls.

The paper investigates how action planning affects perceptual confidence, finding that incongruent action plans increase confidence through enhanced action monitoring.

This study investigates neuronal activity in the primate prefrontal cortex during memory updating tasks and finds that some neurons show transient activity when memory is no longer needed, while others show sustained activity during memory retention.

This study investigates whether the reward positivity (RewP) changes with reinforcer devaluation and finds no significant differences in RewP amplitudes after devaluation.

The paper shows humans reuse learned strategies for new tasks using a computational process involving successor features and generalised policy improvement, supported by neural activation patterns.

This study shows dopamine modulates how much reward attributes influence decisions without changing the integration strategy.

This study shows that lateral orbitofrontal cortex encodes environmental risk and subjective risk preference during decision-making in rats, with risk-preferring rats showing reduced risk encoding and increased reward magnitude encoding.

The paper identifies strategy-dependent roles of direct and indirect striatal projecting neurons in decision-making using a mouse gambling task and reinforcement-learning model.

This paper investigates how stimulus uncertainty and relative reward rates influence adaptive decision-making in rats and pigeons, showing that models incorporating these factors better explain behavior than existing models.
