Total Assignments: Understanding How Each Chimp Independently Chooses Vocalize or Gesture In the fascinating world of primate communication, researchers have long been intrigued by how chimpanzees make vocal and gestural choices during social interactions. A recent focus within primatology explores the concept of “Total Assignments”—a behavioral framework where each individual chimp independently decides whether to vocalize or gesture to communicate. This independent choice, shaped by context, personality, and social dynamics, reveals deep insights into cognitive flexibility and the evolution of communication. ### What Are Total Assignments in Chimpanzee Behavior? In primate behavioral studies, a “Total Assignment” from a chimp’s perspective refers to the distinct option set each individual faces: specifically, whether to vocalize (e.g., hooting, pant-hooting, or screaming) or gesture (e.g., arm raises, hand claps, or facial expressions) when attempting to communicate a message. Unlike group-driven communication systems, where signals are standardized, Total Assignments highlight the autonomy of each chimpanzee in deciding the modality—vocal or gestural—best suited for their situation.
