The study of decision making spans such varied fields as neuroscience, psychology,
economics, statistics, political science, and computer science. Despite this diversity of …

A decision is a commitment to a proposition or plan of action based on information and
values associated with the possible outcomes. The process operates in a flexible timeframe …

Decision making is a core competence for animals and humans acting and surviving in
environments they only partially comprehend, gaining rewards and punishments for their …

When making a decision, one must first accumulate evidence, often over time, and then
select the appropriate action. Here, we present a neural model of decision making that can …

Decisions about sensory stimuli are often based on an accumulation of evidence in time.
When subjects control stimulus duration, the decision terminates when the accumulated …

We conduct an experiment in which subjects face the same questions repeated multiple
times, with repetitions of two types:(1) following the literature, the repetitions are distant from …

Decisions are often based on a combination of new evidence with prior knowledge of the
probable best choice. Optimal combination requires knowledge about the reliability of …

Curiosity—our desire to know—is a fundamental drive in human behaviour, but its
mechanisms are poorly understood. A classical question concerns the curiosity motives …

We model the joint distribution of choice probabilities and decision times in binary decisions
as the solution to a problem of optimal sequential sampling, where the agent is uncertain of …

Decision making often involves a tradeoff between speed and accuracy. Previous studies
indicate that neural activity in the lateral intraparietal area (LIP) represents the gradual …
