title: Acquisition of Key-Pecking via Autoshaping as a Function of Prior Experience: "Learned Laziness"?
abstract: A group of pigeons that had previously received noncontingent food delivery acquired the key-peck response (in autoshape training) more slowly than did a naive control group; key-peck acquisition was most rapid for a group given operant treadle-press training in the initial phase.
