Much recent evidence suggests some dramatic differences in the way people learn
perceptual categories, depending on exactly how the categories were constructed. Four …

During the 1990s and early 2000s, cognitive neuroscience investigations of human category
learning focused on the primary goal of showing that humans have multiple category …

A fundamental question is whether people have available one category learning system, or
many. Most multiple systems advocates postulate one explicit and one implicit system …

This paper presents a systematic review of the empirical literature that uses dual-task
interference methods for investigating the on-line involvement of language in various …

Categorization is a vitally important skill that people use every day. Early theories of
category learning assumed a single learning system, but recent evidence suggests that …

A biologically detailed computational model is described of how categorization judgments
become automatic in tasks that depend on procedural learning. The model assumes 2 …

Theories of mood and its effect on cognitive processing suggest that positive mood may
allow for increased cognitive flexibility. This increased flexibility is associated with the …

The effect of a working-memory—demanding dual task on perceptual category learning was
investigated. In Experiment 1, participants learned unidimensional rule-based or information …

The first neurobiologically detailed theory of multiple systems in category learning, called
COVIS, was originally conceived in 1998. COVIS, which is now well established, postulates …

An emerging theory of the neurobiology of category learning postulates that there are
separate neural systems supporting the learning of categories based on verbalizeable rules …
