I occasionally get requests for materials for psychology classrooms based on the backmasking section of my website. I usually don’t send out materials, but I have been known to make exceptions, especially for professors of post secondary institutions.
I should point out that if you are teaching psychology, you may be interested in material intended for classroom demonstrations by writing John Vokey or Don Read atDepartment of Psychology, University of Lethbridge, Lethbridge, Alberta T1K 3M4 Canada
and requesting University of Lethbridge, Department of Psychology, Technical Report No. 85. A blank cassette tape should be enclosed if classroom demonstrations are desired.
I imagine a blank CD would also work or maybe an empty USB thumb drive, but I would ask them first just to be safe.
