Over the last century scientists have devised many ingenious methods to unlock the secrets of the mind. In this three-part series, host Michael Mosley investigates some of these groundbreaking experiments, now considered classics in the field of psychology. Delving into CIA thought control projects, tests on children, and brain surgery blunders, Into the Mind traces the history of experimental psychology from its dubious beginnings through to the profound new understanding it has yielded of emotions, free will, and the mind itself.
