1. Nonlinear amygdala responses to facial trustworthiness during subliminal and supraliminal presentations.
Nonlinear amygdala responses to facial trustworthiness during subliminal and supraliminal presentations. Top, Coronal slices (y = −1 ± 2) depicting responses associated with a quadratic trustworthiness effect from a random-effects analysis targeting the bilateral amygdala (p < 0.05, corrected). Middle, Mean β values for the linear and quadratic parametric predictors, indexing the strength of the correlations between amygdala response and linear vs quadratic components of trustworthiness, separately for left amygdala (left) and right amygdala (right). Bottom, Mean β values for amygdala BOLD response as a function of facial trustworthiness (for both supraliminal and subliminal conditions), separately for left amygdala (left) and right amygdala (right). Error bars indicate SEM.
