Ernest R. Hilgard
Consciousness can divide, and part of us keeps watching.
American psychologist known for learning theory, hypnosis research and the influential textbook Introduction to Psychology.
Consciousness can be divided, and hidden parts of experience may still register information.
Who they were
Ernest Hilgard studied the edges of awareness. His research on hypnosis suggested that consciousness can split into partly separate streams — that a "hidden observer" may register pain or information the main self does not notice. His work made dissociation a serious subject rather than a curiosity.

Their big idea
Neodissociation Theory
Ernest Hilgard proposed that hypnosis can divide consciousness into partly separate control and monitoring systems, so that a hidden observer may register experiences — such as pain — outside the hypnotized person’s main awareness.
