The new study on free choice

I didn't hear it, but I read the summary. The distinction between pecking and chosing is exactly what I wrote in my book (plus three more arguments). Interestingly, it talks about experiments that dealt with chosing and not just pecking. I highly doubt that such experiments were conducted (I wrote in my book that a friend from the Hebrew University told me that they were working on this. It's a sensitive story and not simple at all). I'll try to listen and then maybe I'll understand more.
