From: Flexible use of multimodal communicative strategies in adult chimpanzees
Individual shifts in chimpanzees’ expression of multimodal communication in social versus non-social contexts. Panels show shifts in the use of multicomponent (a,b) and multisensory (c,d) communicative acts. (a,c) show prediction lines assuming individual chimpanzees adjust their behaviour in the same way between behavioural contexts (random intercept). Because predictors were back-transformed, the lines are not strictly parallel as they are on the logit-scale (i.e. only the intercepts vary). (b,d) show prediction lines assuming individual chimpanzees differ in the extent to which they change their behaviour between behavioural contexts (random intercept and slope). The lack of differences between plots (a) and (b) shows that the random slope does not add significant explanatory power to the model. Colours represent different sex/setting categories.
