Behavioral demands organize a decision process into distinct yet coordinated neural representations in parietal cortex

The paper investigates how behavioral demands shape distinct yet coordinated neural representations in parietal cortex during decision-making.

Behavioral Signatures of Post-Decisional Attention in Preferential Choice

This study reanalyzes food-choice datasets to test models of attention's role in decision-making, finding no support for multiplicative effects and proposing an alternative model that better explains gaze behavior.

The Metacognitive Sensitivity of Verbal and Numerical Confidence Reports

This study compares verbal and numerical confidence reports in perceptual decisions, finding verbal reports more reliable in distinguishing correct from incorrect choices, but equally effective in supporting revisions when combined with partner feedback.

Contrasting Probabilistic and Intentional Accounts of Confidence in Perceptual Decisions

This paper compares probabilistic and intentional models of confidence in perceptual decisions using behavioral data from two tasks, finding task-specific model fits.

Incorporation of a cost of deliberation time in perceptual decision making

The paper tests how time costs affect decision-making by manipulating time pressure in a perceptual task, finding that participants made faster but less accurate decisions.

Population Representation of the Confidence in a Decision in the Parietal Cortex

The paper shows that neurons in the lateral intraparietal area encode confidence in decision accuracy through population-level variability, despite individual neurons showing no correlation with accuracy.

Value construction through sequential sampling explains serial dependencies in decision making

The paper shows that subjective values change during decision-making tasks and introduces a model to detect these changes in choices and neural signals.

Direct observation of the neural computations underlying a single decision

The paper directly observes the neural computations underlying a single decision by analyzing population activity in monkey lateral intraparietal cortex during motion direction decisions.

Judging the difficulty of perceptual decisions

The paper examines how people judge the difficulty of perceptual tasks and finds that decisions are based on accumulated evidence differences rather than confidence.

Sequential sampling from memory underlies action selection during abstract decision making

This study shows that monkeys delay decision formation until motor actions are available, with neurons retrieving evidence from short-term memory during abstract decisions.

Multiple decisions about one object involve parallel sensory acquisition but time-multiplexed evidence incorporation

The paper investigates how the brain processes two decisions about one object, finding parallel sensory acquisition but time-multiplexed evidence incorporation.

Differentiating between integration and non-integration strategies in perceptual decision making

The paper investigates strategies in perceptual decision making, distinguishing between integration and non-integration models and finding that non-integration strategies can mimic integration.

Counterfactual reasoning underlies the learning of priors in decision making

Participants learned base rates from decision-making without feedback by updating their beliefs using counterfactual confidence representations, improving accuracy and confidence.

Value-based decisions involve sequential sampling from memory

The paper shows that decision-making between similar options involves memory-based evidence construction, with hippocampal activity linked to deliberation time and value formation.

Cause for pause before leaping to conclusions about stepping

The paper challenges a recent claim that neuronal firing rate dynamics in LIP represent discrete steps rather than ramp-like diffusion, showing that a mathematical error biased the model comparison.
