A method was developed to test the reinforcing effects of pup retrieval on the behavior of lactating female rats. A modified bar press chamber was employed. One section of the chamber served as the nest area for the mother and young. The female was taught to bar press in order to be admitted to a retrieving area containing a pup which the female could retrieve and return to the nest. The results indicated that high and sustained rates of bar pressing could he obtained using pup retrieval as the reinforcing event. The data obtained using this method were discussed in relation to bar press conditioning employing conventional reinforcers.
