Nesting material as a reinforcer for operant behavior in the rat (1970)

Oley, N. N., Slotnick, B. M.

Abstract

Rats will readily work for the acquisition of nesting material. Paper strips serves as an adequate reinforcer. .. Prior to parturiation, only a small daily nest was built and barpressing occurred only in the dark part of the lighting cycle. Following parturition, barpressing for nesting material greatly increased.
