There is growing interest in diffusion models to represent the cognitive and neural processes
of speeded decision making. Sequential-sampling models like the diffusion model have a …

There are few behavioral effects as ubiquitous as the speed-accuracy tradeoff (SAT). From
insects to rodents to primates, the tendency for decision speed to covary with decision …

Sequential sampling models assume that people make speeded decisions by gradually
accumulating noisy information until a threshold of evidence is reached. In cognitive …

Decisions take time, and as a rule more difficult decisions take more time. But this only
raises the question of what consumes the time. For decisions informed by a sequence of …

Perceptual decision making is the process by which animals detect, discriminate, and
categorize information from the senses. Over the past two decades, understanding how …

Summary" Degree of certainty" refers to the subjective belief, prior to feedback, that a
decision is correct. A reliable estimate of certainty is essential for prediction, learning from …

Human perceptual decisions are often described as optimal. Critics of this view have argued
that claims of optimality are overly flexible and lack explanatory power. Meanwhile …

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 …

This paper aims to integrate some key constructs in the cognitive neuroscience of cognitive
control and executive function by formalising the notion of cognitive (or mental) effort in …

During decision-making, neurons in the orbitofrontal cortex (OFC) sequentially represent the
value of each option in turn, but it is unclear how these dynamics are translated into a choice …
