difference which was observed on an explicit level, disappeared when measured implicitly.
An important consideration when studying emotions comparatively are the differences in species’ physique. Although there are few anatomical differences between humans and bonobos (Diogo, 2018), other differences, such as the fact that bonobos have fur and humans walk bipedally and stand up straight, may make the transmission of certain emotions easier in one species than the other. Bonobos have much larger canines than humans. These canines stand out and could provide a threat signal. Interestingly, humans’ attention was captured more by human yawns than by bonobo yawns, an effect that is more likely to be explained by the highly contagious nature of this stimulus, which is typically enhanced when shown by close others (Palagi et al., 2014). From that point of view, the difference in height between children and adults and their subsequent different viewing angle when reading adults facial expressions, may impact in how these are perceived and learned.
