The dominant view that perceptual learning is accompanied by changes in early sensory
representations has recently been challenged. Here we tested the idea that perceptual …

Making successful decisions under uncertainty due to noisy sensory signals is thought to
benefit from previous experience. However, the human brain mechanisms that mediate …

An emerging view in perceptual learning is that improvements in perceptual sensitivity are
not only due to enhancements in early sensory representations but also due to changes in …

Little is known about the relationship between attention and learning during decision
making. Using eye tracking and multivariate pattern analysis of fMRI data, we measured …

It is well established that learning can occur without external feedback, yet normative
reinforcement learning theories have difficulties explaining such instances of learning. Here …

A growing body of research—including results from behavioral psychology, human structural
and functional imaging, single-cell recordings in nonhuman primates, and computational …

Adaptively interacting with our environment requires extracting information that will allow us
to successfully predict reward. This can be a challenge, particularly when there are many …

We recently showed that improved perceptual performance on a visual motion direction–
discrimination task corresponds to changes in how an unmodified sensory representation in …

The way that we interpret and interact with the world entails making decisions on the basis of
available sensory evidence. Recent primate neurophysiology [1–6], human neuroimaging [7 …

Although practice has long been known to improve perceptual performance, the neural
basis of this improvement in humans remains unclear. Using fMRI in conjunction with a …
