Audible Gestures

Visual Attention:  In Kubie's gesturing to Zura a medium percentage of audible gestures were performed when Kubie had Zura's visual attention.

Playface:  A very low percentage of audible gestures were performed with a playface from Kubie.

Contact:  Contact between gorillas resulted at medium or low rates (lowest for chestbeat), but there were high rates of approach or change of locomotor activity, and of gaze direction after a chestbeat or knocks.

Context:  Contexts for audible gestures were games with visual barriers between gorillas (trees or rocks), and for chestbeat, a long distance separation between gorillas.

Video Examples: chestbeat, clap, knock, slap.
