Evidence accumulation models have enabled strong advances in our understanding of
decision-making, yet their application to examining learning has not been common. Using …

How do we combine memories with sensory input to make decisions? Previous research
has shown that perceptual decisions can be made on the basis of prior expectations …

Perceptual decision-making involves multiple cognitive processes, including accumulation
of sensory evidence, planning, and executing a motor action. How these processes are …

Abstract We investigate Ornstein–Uhlenbeck and diffusion processes with variable drift rates
as models of evidence accumulation in a visual discrimination task. We derive power-law …

Taking other people's interests into account is a fundamental ability allowing humans to
maintain relationships. Yet, the mechanisms by which monetary incentives for close others …

When people make decisions, do they give equal weight to evidence arriving at different
times? A recent study (Kiani et al.,) using brief motion pulses (superimposed on a random …

Standard models of perceptual decision-making postulate that a response is triggered in
reaction to stimulus presentation when the accumulated stimulus evidence reaches a …

Two phenomena are commonly observed in decision-making. First, there is a speed-
accuracy tradeoff (SAT) such that decisions are slower and more accurate when instructions …

Perceptual choices depend not only on the current sensory input but also on the behavioral
context, such as the history of one's own choices. Yet, it remains unknown how such history …

Human subjects exhibit “sequential effects” in many psychological experiments, in which
they respond more rapidly and accurately to a stimulus when it reinforces a local pattern in …
