Lisa Feldman Barrett

American psychologist and neuroscientist. University Distinguished Professor of Psychology at Northeastern University since 2008, with research appointments in the Department of Psychiatry at Massachusetts General Hospital and at Harvard Medical School. PhD from the University of Waterloo in 1992; earlier positions at Penn State and Boston College. Founder and director of the Interdisciplinary Affective Science Laboratory at Northeastern. The principal architect and public advocate of the theory of constructed emotion.

Stake§

Barrett's stake is theoretical and disciplinary. The theory of constructed emotion has been her central programme for two decades, and she has built it across journal articles, two trade books (How Emotions Are Made, 2017; Seven and a Half Lessons About the Brain, 2020), and substantial public-facing communication. The position is in direct opposition to the basic- emotion tradition (Paul Ekman, Jaak Panksepp, Joseph LeDoux), and the disagreement is professional, sometimes pointed. Her career arc is also defined by advocacy for psychological-science methodology (she served as President of the Association for Psychological Science) and for women in neuroscience.

Barrett's foundational move, made in collaboration with W. Kyle Simmons in Interoceptive predictions in the brain (2015), was the embodied- predictive-interoception-coding (EPIC) model — a specific architectural proposal that integrates corticocortical anatomy with Bayesian active inference. The agranular visceromotor cortices generate top-down predictions about expected body state; the ascending afferents from the periphery are compared against these predictions; the prediction errors are what enter awareness as emotion. The model is the empirical-anatomical companion to her broader theory of constructed emotion.

The theory itself — that emotions are not biologically pre-wired categories but are constructed in the moment from interoceptive prediction, conceptual knowledge, and situational context — is in direct tension with the Craig 2002 direct-readout model of interoception. Where Craig has the right anterior insula as the substrate of feeling, Barrett and Simmons have feeling constructed across the distributed visceromotor network, with the insula playing a comparator role rather than a feeling-generator role. The 2018 Khalsa Roadmap treats both positions as legitimate.

The public-facing argument-making has costs and benefits. The benefit: How Emotions Are Made has done more than any other single piece of writing to bring the constructionist view of emotion to non-specialist audiences. The cost: the disagreements with the basic-emotion tradition have sometimes been adjudicated in popular media rather than journals, and the resulting controversies — the facial expressions don't reveal universal emotion line in particular — are partly genuine science disagreement and partly the inevitable distortion of nuance in popularisation. The journal literature is the substantive site; the trade books are careful but distillation-flavoured.
