Attention: In
Kubie's gesturing to Zura a high percentage of visual gestures (83-100% depending on gesture) were performed when Kubie had,
or made sure he got, Zura's visual attention.
Playface:
The percentage of visual gestures performed with a
playface varied by gesture type from low to high (11-57%).
Contact: A high percentage of contact (59-79% depending on gesture) between the gorillas
resulted soon after Kubie's visual gestures;
most of these contacts (76%) were initiated by Zura.
Context:
Visual gestures were most frequent in game contexts of keep-away and chasing at
relatively close distances.
