Professor Zelazo studies the development and neural bases of
executive function, or the conscious control of thought, action, and
emotion. He does so using a variety of approaches, from experimental
to cross-cultural to electrophysiological (EEG/ERP), and his work
has focussed on a number of influential ideas, including the notion
that the executive function depends, in part, on the development of
the ability to use increasingly complex, higher-order rules
(formulated in self-directed speech)—part of the Cognitive
Complexity & Control theory; the notion that consciousness develops
through a series of “levels” in which information is reprocessed via
thalamo-cortical circuits involving prefrontal cortex (the Levels of
Consciousness model)—with consequences for the quality of subjective
experience, and the potential for recall, rule complexity, and
cognitive control; and the importance of the distinction between
more “cool,” cognitive aspects of executive function typically
associated with dorsolateral prefrontal cortex (DL-PFC) vs. more
“hot,” affective aspects associated with more ventral and medial
regions of PFC (e.g., orbitofrontal cortex; OFC).
