Lisa Feldman Barrett
Neuroscientist whose theory of constructed emotion is the most sophisticated contemporary challenge to Damasio's framework — and whose critique, while forcing modifications, has left the core somatic claim intact.
Lisa Feldman Barrett is a University Distinguished Professor of Psychology at Northeastern University whose theory of constructed emotion has fundamentally reshaped emotion research over the past two decades. Her work challenges the assumption — shared by Damasio's original somatic marker hypothesis — that emotions are natural kinds with specific neural signatures and universal bodily profiles. In Barrett's view, emotions are actively constructed by the brain from undifferentiated arousal, shaped by context, prior experience, and cultural categories. Her framework requires modification of the somatic marker hypothesis without overturning its core claim that bodily signals contribute to practical judgment.

Barrett's research program, developed through the 2000s and 2010s and synthesized in her 2017 book How Emotions Are Made, has produced substantial empirical evidence against the "classical view" of emotions as biologically hardwired categories. Meta-analyses of neuroimaging studies, electromyographic research on facial expressions, and cross-cultural studies of emotion concepts all converge on a picture in which emotional experience
