The role of movement kinematics in facial emotion expression production and recognition.

Follow-up RM-ANOVAs demonstrated (a) a significant interaction between emotion and face action for both posing [ F (5.18, 341.52) = 37.65, p < .001, η p 2 = .36] and spoken [ F (5.52, 364.20) = 13.45, p < .001, η p 2 = .17] conditions, (b) a significant Emotion × Condition interaction for all face areas (all p s < .05; though the interaction for nose lengthening was marginally significant, p = .04), and (c) a significant Face Action × Condition interaction for happy [ F (2.94, 193.76) = 214.92, p < .001, η p 2 = .77], angry [ F (2.98, 196.62) = 393.56, p < .001, η p 2 = .86], and sad [ F (2.88, 189.95) = 255.84, p < .001, η p 2 = .80].

Although again note that this effect is only trending toward significance at a Bonferroni-corrected alpha cutoff of 0.0167.
