Effects of association partners on reactions to the experiment apparatus. (A) Looking durations at the experiment apparatus, (B) latencies to approach the experiment apparatus, (C) approach distances towards the experiment apparatus, (D) the probability of signs of agitation during the experimental trial, (E) the probability of touching the apparatus, and (F) the latency to leave the vicinity of the experiment apparatus when there was no association partner (party) approaching the experiment apparatus versus when there was. For panels (A–C) and (F), each data point represents one experimental trial on one focal individual with colors referring to different individuals. The grey boxes show the interquartile ranges, the whiskers extend to the maximum and minimum data points that are within 1.5 times the interquartile range from the upper and lower quartiles, and the grey horizonal lines represent the medians. For panels D and E, the grey columns represent the average proportion of trials with agitation/touch for each age-sex class (with the number of trials with agitation/touch over the total number of trials per age-sex class indicated under each grey bar) and the data points each show one individual’s proportion of trials with agitation; the size of each data point represents the number of trials for that individual. In all panels, the thick black horizontal lines represent mean model predictions when holding all other predictor variables at their means and the data points with black borders depict the first trial of each individual.
