Resumen de Impulsive? You lack 'free won't'
Being impulsive could be the result of not having enough time to veto people's own actions. At least that's the implication of a twist on a classic experiment on free will. In 1983, neuroscientist Benjamin Libet wanted to test whether they have free will. He asked participants to sporadically flex a finger while watching a dot rotate round a clock-face. They had to note the position of the dot as soon as they became aware of their intention to act, while their brain activity was being recorded. Libet found that a spike in brain activity called the readiness potential, which precedes a voluntary action, occurred about 350-milliseconds before the volunteers became consciously aware of their intention to move their finger. The readiness potential is thought to signal the brain preparing for movement
