Abstract The replicability of emotion-related physiological changes constitutes a fundamental issue in affective science. We undertook a direct replication of the physiological differentiation of amusement, disgust, and a mixed emotional state as previously reported (Kreibig, Samson, & Gross, 2013). In the current study, 48 women watched 54 amusing, disgusting, and mixed emotional film clips while cardiovascular, electrodermal, and respiratory measures were obtained. Primary analyses indicated physiological differentiation of the mixed emotional state from amusement and disgust. We evaluated (a) the probability that future replications of the current study would yield similar results using bootstrapped confidence intervals of effect sizes, and (b) the stability of results of physiological reactivity between actual replications using correlation and regression analyses. Findings suggest replicable differentiation of amusement, disgust, and a mixed emotional state.
