Yes, my brain is being pulled away from what I am trying to focus on. My mind is not empty at all. lol.
One of the Piaget examples you are talking about has to do with conservation of liquid.
Obviously the child gets it wrong until he learns the conservation concept. Everything must come from experience according to Skinner. So this is consistent with Skinner. But now take different sized and shaped containers. Skinner assumed that the child would have to be retaught the conservation concept because he never experienced this particular setup. He didn't think the concept would be "conserved" through various different experiments but it was. The children held onto the concept and could apply it to all kinds of things now.
