Predicted values of reaction times (log) for Analysis 2. a Interaction between speech clarity and congruency. b Interaction between congruency and gesture informativeness. c Interaction between speech clarity and mouth informativeness. For a–b, dark blue represents congruent gestures, whereas orange represents incongruent gestures. For c, dark purple refers to clear speech, and green refers to vocoded speech. The larger the value of gesture informativeness, the more informative the gestures are; the smaller the value of mouth informativeness, the more informative the mouth movements are. Confidence intervals are set to 95%
