Part 6/12:
A landmark experiment by Benjamin Libet in the early 1980s challenged traditional notions of conscious decision-making. Libet's study involved measuring neural activity and the awareness of intention when participants decided to flex their hands. Remarkably, brain signals indicating an intention to move appeared about 200 milliseconds before participants reported conscious awareness of the decision. This led to the provocative suggestion that unconscious brain processes initiate actions before the individual becomes consciously aware of their choice.
