Table 1 Parameter estimates for linear mixed-effect models for response duration (N = 37) and approach distance (N = 37) as a function of playback (PB) type (second- or third-order alliance), social bond strength (SRI), number of consortships (Consort) and PB order on a given day for a given subject.
