Predicted effect of the interaction of actor and receiver’s swelling state on the dyadic grooming preference. Dots with borders and whiskers indicate estimated mean and standard errors of categorical responses, while colored lines indicate variation in receiver’s effect according to actor’s swelling. The figure is plotted with all other predictors at their average value. Dots without borders indicate raw data plotted with jitter function at 0.1 (width). Parentheses indicate significant post-hoc comparison.
