APERIODICITY AS A FACTOR IN CHOICE

R J HERRNSTEIN. J Exp Anal Behav. 1964 Mar.

Abstract

Four pigeons were trained to peck at either of two response-keys. Pecks at either key occasionally produced a secondary reinforcer, in the presence of which further pecks occasionally produced food, the primary reinforcer. All pigeons showed a consistent preference for variable (as compared to fixed) interval schedules of primary reinforcement.
