Figure 4. Experiment 1: Bonobos show an attentional bias towards emotions of unfamiliar, but not familiar conspecifics (top left). Experiment 2: Bonobos do not show an attentional bias towards emotions of familiar or unfamiliar humans (top right). Experiment 3: Humans have an attentional bias towards emotional expressions of familiar others (bottom left). To illustrate an attentional bias, we calculated the difference between mean reaction times (RTs) on neutral scenes minus mean RTs on emotional scenes per condition (Unfamiliar, Familiar). Bars in the positive direction indicate a bias towards emotional scenes or expressions rather than to neutral scenes or expressions. Error bars represent the SEM. * p < .05.
