In the study with the spot of light going around a clock, the time when activity began in the motor cortex of the brain was earlier than the time of the reported decision, implying that the brain starts producing a response before the person makes a conscious decision to move. What limitation in this study leads some people to doubt that conclusion?
What will be an ideal response?
People can fairly accurately report the time of a stimulus or the time of an action, but they may not be able to report the time of a conscious decision. A conscious decision to move is a gradual process, and therefore describing the time of the decision may be no more than guesswork.
