Perceptual decision making is a complex process that requires multiple computations,
including the accumulation of sensory evidence and an ongoing evaluation of the …

Neurons in early sensory cortex show weak but systematic correlations with perceptual
decisions when trained animals perform at psychophysical threshold. These correlations are …

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 …

Our ability to make rapid decisions based on sensory information belies the complexity of
the underlying computations. Recently,“accumulator” models of decision making have been …

To interact successfully with diverse sensory environments, we must adapt our decision
processes to account for time constraints and prior probabilities. The full set of decision …

Categorical choices are preceded by the accumulation of sensory evidence in favor of one
action or another. Current models describe evidence accumulation as a continuous process …

Choice confidence represents the degree of belief that one's actions are likely to be correct
or rewarding and plays a critical role in optimizing our decisions. Despite progress in …

Previous studies and models of perceptual decision making have largely focused on binary
choices. However, we often have to choose from multiple alternatives. To study the neural …

Neuroscience has paid only little attention to decision-making for many years. Although no
field of science has cohered around this topic, a variety of researchers in different areas of …

In the last two decades, animal neurophysiology research has made great strides towards
explaining how the brain can enable adaptive action in the face of noisy sensory …
