  • Title: Social reinforcement of operant behavior in rats: a methodological note.
    Author: Evans MJ, Duvel A, Funk ML, Lehman B, Sparrow J, Watson NT, Neuringer A.
    Journal: J Exp Anal Behav; 1994 Jul; 62(1):149-56. PubMed ID: 8064210.
    Abstract:
    An apparatus was developed to study social reinforcement in the rat. Four Long-Evans female rats were trained to press a lever via shaping, with the reinforcer being access to a castrated male rat. Responding under a fixed-ratio schedule and in extinction was also observed. Social access was found to be an effective reinforcer. When social reinforcement was compared with food reinforcement under similar conditions of deprivation and reinforcer duration, no significant differences were observed.
