We propose that the entirety of the prefrontal cortex (PFC) can be seen as fundamentally
premotor in nature. By this, we mean that the PFC consists of an action abstraction hierarchy …

Modeling human cognition is challenging because there are infinitely many mechanisms
that can generate any given observation. Some researchers address this by constraining the …

A major goal of psycholinguistic theory is to account for the cognitive constraints limiting the
speed and ease of language comprehension and production. Wide-ranging evidence …

Short-term verbal memory is improved when words can be chunked into larger units. Miller
(1956) suggested that the capacity of verbal short-term memory is determined by the number …

Preference-based decisions are essential for survival, for instance, when deciding what we
should (not) eat. Despite their importance, preference-based decisions are surprisingly …

I apply a recently emerging perspective on the complexity of action selection, the rate–
distortion theory of control, to provide a computational-level model of errors and difficulties in …

People can identify the number of objects in sets of four or fewer items with near-perfect
accuracy but exhibit linearly increasing error for larger sets. Some researchers have taken …

Perceptual generalization and discrimination are fundamental cognitive abilities. For
example, if a bird eats a poisonous butterfly, it will learn to avoid preying on that species …

In statistics and machine learning, model accuracy is traded off with complexity, which can
be viewed as the amount of information extracted from the data. Here, we discuss how …

Words categorize the semantic fields they refer to in ways that maximize communication
accuracy while minimizing complexity. Focusing on the well-studied color domain, we show …
