Classical models of perceptual decision-making assume that subjects use a single,
consistent strategy to form decisions, or that decision-making strategies evolve slowly over …

Trial history biases and lapses are two of the most common suboptimalities observed during
perceptual decision-making. These suboptimalities are routinely assumed to arise from …

Olfaction is fundamentally distinct from other sensory modalities. Natural odor stimuli are
complex mixtures of volatile chemicals that interact in the nose with a receptor array that, in …

Progress in science requires standardized assays whose results can be readily shared,
compared, and reproduced across laboratories. Reproducibility, however, has been a …

Learning from successes and failures often improves the quality of subsequent decisions.
Past outcomes, however, should not influence purely perceptual decisions after task …

Making optimal decisions in the face of noise requires balancing short-term speed and
accuracy. But a theory of optimality should account for the fact that short-term speed can …

Everyday decisions frequently require choosing among multiple alternatives. Yet the optimal
policy for such decisions is unknown. Here we derive the normative policy for general multi …

Perceptual decision-makers often display a constant rate of errors independent of evidence
strength. These 'lapses' are treated as a nuisance arising from noise tangential to the …

Although Weber's law is the most firmly established regularity in sensation, no principled
way has been identified to choose between its many proposed explanations. We …

The neural representations of prior information about the state of the world are poorly
understood. To investigate this issue, we examined brain-wide Neuropixels recordings and …
