Hey Stef, great video!
I had a negative emotional reaction to one of your sources, however: http://thesituationist.wordpress.com/2007/11/20/the-unconscious-situation-of-our-consciousness-part-ii/
I read the article, and I don't have a problem with the idea of people wrongly attributing an action or event to their will. Many of the experiments seem to demonstrate this. But the first experiment mentioned, where the readiness potential (RP) of moving a finger is measured and compared to when a subject reports that they have decided to move their finger, seems poorly constructed, and I think the implications of the experiment are much farther reaching than the authors seem to suggest.
My understanding is that there was no priming or external manipulation of any kind in this particular experiment to influence the individuals' perception of their will. So if this experiment were valid, it seems that it would imply that all of our actions are not actually willed by us, which is a much stronger claim than that people often think they have willed actions that they have in fact not. For this reason, I think it is important to point out what I think are this experiment's flaws.
My main criticism is that they are relying on the subjects verbally expressing when they have made the decision to move their finger, and they are claiming that the moment that the subject reports this decision is the moment that the subject experiences having made the decision. I believe this contradicts their observation that there is a 0.5 second delay between the RP onsetting and the subject's finger actually moving. Speaking is an action in itself and if we assume that there is a similar delay for speaking, then the RP for saying "I decided to lift my finger" should have actually onset before the RP for moving the finger, which would imply that the subject experienced having made the decision before the RP for moving the finger onset. This contradicts their conclusions.
I imagine that the two RPs could overlap and there could be different delays for different types of actions, so that greatly complicates measuring them. This experiment does not prove that the subjects did not will their fingers to move because when the subjects experience making the decision could be at precisely the same moment that the RP onsets, there is simply a delay between them making the decision and them reporting it. It only shows that there is a delay between deciding and acting.
What do you think? Or am I guilty of trying to rationalize my biases
