The collective activity of a population of neurons, beyond the properties of individual cells, is
crucial for many brain functions. A fundamental question is how activity correlations between …

The replication crisis facing the psychological sciences is widely regarded as rooted in
methodological or statistical shortcomings. We argue that a large part of the problem is the …

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 …

How is it that thoroughly physical material beings such as ourselves can think, dream, feel,
create and understand ideas, theories and concepts? How does mere matter give rise to all …

When facing uncertainty, adaptive behavioral strategies demand that the brain performs
probabilistic computations. In this probabilistic framework, the notion of certainty and …

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

Economic choice behavior entails the computation and comparison of subjective values. A
central contribution of neuroeconomics has been to show that subjective values are …

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 …

Cognition results from interactions among functionally specialized but widely distributed
brain regions; however, neuroscience has so far largely focused on characterizing the …

An outstanding challenge for consciousness research is to characterize the neural signature
of conscious access independently of any decisional processes. Here we present a model …
