Questions About Dr D Ewen Cameron

CIA mind control

I was reading about psychic driving which is a CIA and psychotherapy technique to change human behavior. What I wonder is what kind of messages did they play to them? The same ones over and over? Different ones mixed together? what kind of things did they say? Seeing as how it was done by Dr. D. Ewen Cameron at a legitimate University under the guise of legitimate psychiatric research , I would imagine he would have released peer reviewed medical journals detailing his techniques, their effectiveness ect including what messages he played to them. What I am particularity interested in is what kind of things were said on the tape they played
