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 is more variable and more constructed than classical theories assumed.
The theoretical framework draws on predictive processing models of cognition. On Barrett's account, the brain is a prediction engine that constructs emotional meanings from the body's continuous interoceptive signals, using prior experience and conceptual knowledge to disambiguate what would otherwise be raw arousal.
The challenge to Damasio is precise. If emotions are not discrete natural kinds, then somatic markers cannot be discrete evaluative signals of the "this is dangerous" or "this is promising" variety. They would be undifferentiated arousal that the brain categorizes through interpretation. Damasio's framework requires the markers to do evaluative work, but the nature of that work must be reconceived.
Barrett's critique has been productive rather than destructive. It forces specification of what kind of bodily signal somatic markers actually are — arousal plus interpretation rather than pre-packaged evaluation. This specification has implications for AI: if construction matters, then the quality of the interpretive framework a decision-maker brings to bodily signals becomes as important as the presence of the signals themselves.
The two researchers have sparred publicly at conferences, in journal exchanges, and in popular media. The exchanges have been substantive rather than personal, and both have acknowledged that the other's work has refined their own thinking.
Barrett received her PhD in clinical psychology and developed the theory of constructed emotion over more than two decades of research at Boston College and Northeastern University. Her work has earned her a Guggenheim Fellowship, election to the American Academy of Arts and Sciences, and the NIH Director's Pioneer Award.
Emotions are constructed, not discovered. They are not natural kinds retrieved from dedicated circuits but active interpretations constructed by the brain from continuous bodily signals.
Context and concepts matter. The same physiological arousal can become excitement or anxiety depending on context, prior experience, and available emotion concepts.
Interoception is foundational. The brain's ongoing monitoring of bodily states provides the raw material from which emotional meanings are constructed.
The critique refines rather than refutes Damasio. The claim that bodily signals contribute to judgment survives; the claim about what kind of signal they are is modified.
Somatic literacy matters. If emotions are constructed, the quality of the construction depends on the conceptual frameworks and bodily attention the person brings — making training and practice constitutive of evaluative capacity.
