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

The past decade has seen the emergence of the use of reinforcement learning models to
study developmental change in value-based learning. It is unclear, however, whether these …

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 …

Decision-makers often arrive at different choices when faced with repeated presentations of
the same evidence. Variability of behavior is commonly attributed to noise in the brain's …

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 …

Perceptual decision-making is highly dependent on the momentary arousal state of the
brain, which fluctuates over time on a scale of hours, minutes, and even seconds. The …

The ability to process and respond to external input is critical for adaptive behavior. Why,
then, do neural and behavioral responses vary across repeated presentations of the same …

When learning the value of actions in volatile environments, humans often make seemingly
irrational decisions that fail to maximize expected value. We reasoned that these 'non …

An organism's survival depends on its ability to learn about its environment and to make
adaptive decisions in the service of achieving the best possible outcomes in that …

Convolutional neural networks show promise as models of biological vision. However, their
decision behaviour, including the facts that they are deterministic and use equal numbers of …
