What this study supports

Reports considerable autonomic response specificity when emotion subtypes are considered. It is never cited as evidence against autonomic fingerprints; it is cited only as a partial counterpoint to Siegel et al. (2018), and claims citing both must say so.

Who was studied
Review of 134 publications of experimental emotion effects on peripheral physiology in healthy people.
Design
Review
Level of evidence
Cross-sectional, observational, qualitative work and narrative reviews.

Claims that rest on it

Each claim states what the site asserts, at what strength, and with what caveat.

EmpiricalLevel AConfidence MODERATE

A meta-analysis of 202 studies found that autonomic nervous system responses did not clearly distinguish one emotion category from another and varied substantially within categories; an earlier review of 134 publications, a partial counterpoint, reported considerable specificity when emotion subtypes are considered.

Scope
Laboratory emotion inductions in nonclinical adults, measured with peripheral physiology.
Caveat
The two syntheses disagree on specificity, so the claim is that no consistent fingerprint has been established, not that physiology is uninformative.

EmpiricalLevel AConfidence MODERATE

Meta-analyses found little evidence that discrete emotion categories map consistently and specifically onto distinct brain regions or autonomic response patterns; an earlier review, a partial counterpoint, reported considerable autonomic specificity when emotion subtypes are considered.

Scope
Laboratory neuroimaging and psychophysiology studies of emotion categories.
Caveat
Absence of a consistent signature across studies does not show that categories are unreal; multivariate methods and different inductions may yield different patterns.
