We discuss possible interpretations of these findings, from attentional difficulties with the task, to the possibility that fast mapping evolved in humans since the split from a common ape ancestor.

Using eye tracking, we find no evidence of fast mapping - the ability to rapidly associate a sound with an object, and a key component of language acquisition - in gorillas and orangutans, in contrast to humans.

I hope you measured his face 😆

Initial agency detection in scenes depicting inanimate patients is clearly quicker than in social interactions. It makes sense, since an animate person has a much higher chance of being an agent than an inanimate object.

To add: I wouldn't exactly caution against the use of static stimuli to study event apprehension. I think it's jsut important to note that different approaches require different respones from participants, and this produces different results.

Thanks Denis! Actions involving food were varied - some involved eating, others involved nut cracking or carrying food - so I don't think there's a consistent difference in goal-directed behaviour amongst those scenes that could differentiate them from non-food scenes.
