Abstract
Three groups of rats (C, D, and E) each received, during a daily session, two runway trials in one-half of a differential conditioning apparatus to one-pellet reward. Groups C and E also received one and 12 pellets, respectively, in a placement cage twice during a session. Group D received two additional 12-pellet trials in the other half of the differential conditioning apparatus. The S— (one-pellet) speeds of Group D over the later stages of training were significantly below the approximately equivalent performance level attained by Groups E and C.
