Imitative Learning
Learning that reproduces not just the result of observed behavior but the goal and method behind it—the cognitive capacity distinguishing human cultural learning from chimpanzee emulation and enabling the cultural ratchet.
Imitative learning is the specific form of social learning that makes cumulative culture possible. When a chimpanzee observes another cracking nuts with stones, it may learn that stones can open nuts (emulation learning) and develop its own technique for achieving the result. When a human child observes the same behavior, the child reproduces the specific method—the grip, the angle, the sequence of actions—because the child infers the demonstrator's goal and adopts the method as the way to achieve it. This difference appears subtle but is profound. Emulation preserves results; imitation preserves understanding. The ratchet requires the latter, because innovation depends on understanding what the inherited technique accomplishes and how it might be improved. Tomasello's experiments demonstrated that human children, by fourteen months, engage in true imitation while great apes rely primarily on emulation even after extensive observation.
