"Back in 2006, Eagleman and his team conducted an experiment in which subjects were simply asked to press a button. Doing so would instantly cause a nearby light bulb to blink. The researchers then added a slight tenth of a second delay between the press of the button and the light coming on and asked subjects to continue pressing the button. For the grand finale, the researchers removed the delay and watched as something completely perplexing happened. The subjects, utterly flabbergasted, insisted that the light would come on before they even pressed the button!
For Eagleman, this was an "Ah ha!" moment. Schizophrenics, he says, suffer from something called credit misattribution -- they believe that theyâ€™re not causing their own actions. What if this is because their brainâ€™s perception of time is off, thus causing an actionâ€™s effect to seem to occur before the cause?"

That's an interesting idea. The brain imaging studies suggest the attribution of the voices to something or someone other than oneself results from the fact that they are being generated by the right (or non-dominant) hemisphere language areas, whereas one's sense of self is associated with the left or language dominant hemisphere. These studies vindicate Jaynes's neurological model.
