I think that this should be studied alot deeper. I would suggest it would be interesting to compare response times between adults and children, between a common adult and a Buddhist (example) adult. What if one lives a life trained to be responsive instead of reactionary? How does this effect the neuron responses to physical actions? As we grow our energy bodies learn physical reactions to frequencies we encounter. Some good some bad, once we are adults we have trained our energy bodies to auto respond when encountering said frequencies. Sarcasm frequency = response laughter / challenge frequency = response fear etc. How we handle the 1st encounters with these frequencies will be the programing for our energy body. So children are not fully programed and may show different areas of response in the brain and different response times. Spiritual people are trying to attain a point of not reacting to things but more so responding with thought and sort of disconnected from the outcome of the stimuli and therefore may also show different than an average study subject. Free will may be greatly impacted by the study subjects understanding of what that means. Some people are followers and some people are leaders. Some people react to life, some people respond. I think diving into the later would take this science to a new perspective of how our concious and subconscious coexist.

I believe that people do have free will. Unfortunately most people fall victim to reactionary responses. If a person is yelled at as a child, and that child runs and hides and in turn feels safe, I predict that in the future they will also run and hide when faced with fear, without much thought at all. The body has learned that when faced with frequency of aggression the reaction is to hide. Our power of free will comes in when we resist the urge to react and hide, and choose to respond differently. What separates man from machine is our power to function outside of our programming, and break free from our own negative algorithms.
