KEY PEOPLE

Sigmund Freud (1856–1939) Austrian physician and founder of psychoanalysis; proposed that dream images are disguised and symbolic expressions of unconscious wishes and urges.

Ernest R. Hilgard (1904–2001) American psychologist who extensively studied hypnosis and advanced the neodissociation theory of hypnosis.

Robert W. McCarley (b. 1937) Contemporary American psychiatrist and neuroscientist who has extensively studied the brain controls involved in sleep and dreaming; along with co-researcher J. Allan Hobson, proposed the activation-synthesis model of dreaming.

J. Allan Hobson (b. 1933) Contemporary American psychiatrist and neuroscientist who has extensively studied the neuropsychological events associated with sleep and dreaming; along with co-researcher Robert W. McCarley, proposed the activation-synthesis model of dreaming.

William James (1842–1910) American psychologist and philosopher who proposed that the subjective experience of consciousness is not episodic, but an ongoing stream of mental activity.

If the act of circling an eye distracted you and you fell for the trick—as most people do—you have just experienced change blindness.
