Behavior varies from trial to trial even when the stimulus is maintained as constant as
possible. In many models, this variability is attributed to noise in the brain. Here, we propose …

It is often suggested that decisions are made when accumulated sensory information
reaches a fixed accuracy criterion. This is supported by many studies showing a gradual …

Optimal binary perceptual decision making requires accumulation of evidence in the form of
a probability distribution that specifies the probability of the choices being correct given the …

This essay reviews recent developments in neurobiology which are beginning to expose the
mechanisms that underlie some elements of decision-making that bear on attributions of …

To make fast and accurate behavioral choices, we need to integrate noisy sensory input,
take prior knowledge into account, and adjust our decision criteria. It was shown previously …

This article argues that conscious attention exists not so much for selecting an immediate
action as for using the current task to focus specialized learning for the action-selection …

How does the brain combine prior knowledge with sensory evidence when making
decisions under uncertainty? Two competing descriptive models have been proposed …

Decision making demands the accumulation of sensory evidence over time. Questions
remain about how this occurs, but recent years have seen progress on several fronts. The …
