Fig 1.
Proportion of observations in each proximity category in the outgroup and control conditions in a) the playback phase and b) the post phase. Each dot represents a dyad, blue circles represent the mean for the control condition, and red X’s represent the mean for the outgroup condition. Red and blue bars represent 95% confidence intervals around the mean (based on a non-parametric bootstrap of the data).

Behaviors in the playback and post phases.
Self-directed behaviour in the playback phase, and social grooming in both the playback and post phase, had significant interactions between condition and trial, with the main effect of condition visualized here (graphs depicting trial interactions can be found in S1 File). Each dot represents an individual, blue circles represent the mean for the control condition, and red X’s represent the mean for the outgroup condition. Red and blue bars represent 95% confidence intervals around the mean (based on a non-parametric bootstrap of the data).
