Chimpanzees use facial expressions, postures, and sounds to communicate with each other. Chimpanzees have expressive faces that are important in close-up communications. When frightened, a "full closed grin" causes nearby individuals to be fearful, as well. Playful chimpanzees display an open-mouthed grin.

[ citation needed ] Chimpanzees have a laryngeal structure very different from that of humans, and it has been suggested that chimpanzees are not capable of voluntary control of their breathing, although better ...
Specifically, chimpanzees were shown video clips of emotionally charged scenes, such as a detested veterinary procedure or a favorite food, and then were required to match these scenes with one of two species-specific facial expressions: "happy" (a play-face) or "sad" (a teeth-baring expression seen in frustration or after defeat).
Chimpanzees communicate in a manner that is similar to that of human nonverbal communication, using vocalizations, hand gestures, and facial expressions. There is some evidence that they can recreate human speech. [76]
One study analyzed sounds made by human babies and bonobos when tickled. It found that although the bonobo's laugh was a higher frequency, the laugh followed the same sonographic pattern as human babies and included similar facial expressions. Humans and chimpanzees share similar ticklish areas of the body such as the armpits and belly. [6]
