- 4.1: Nonverbal Communication Among Primates
- Nonverbal communication involves conveying messages without words, often through gestures, facial expressions, and body language. It varies significantly among individuals and cultures. While humans use these cues alongside verbal language, non-human primates primarily rely on a call system, which consists of 15-40 vocal sounds for communicating basic needs and emotions. This "closed" system lacks displacement and arbitrariness traits present in human language.
