Examples of a point gesture. Point involves extending an arm with the index finger extended toward an object without touching it. Left: ape example – The caregiver asks Panpanzee (22 months, 20 days) where she wants to go and she points toward the car. They walk toward the car. Right: human example – GN (13 months, 9 days) points at picture on fridge while vocalizing. “What do you see?” Mom asks. “There’s GD in a picture,” Mom continues. GN points again (not shown) and then turns to point at actual GD, her older brother, who is out of view.
