Video showing conditioned head-turn?

[Lynn Santelmann]

Does anyone know of a video showing the conditioned head-turn
procedure? I would like be able to show this for an upcoming unit in
my psycholinguistics class, but can't seem to find one. (I know that
one exists because I saw one several years ago, but can't for the
life of me remember what it was.)

Thanks for hte help,
