Abstract
Three groups of 10 rats each received 64 acquisition and 64 postshift trials in an L-shaped double-alley apparatus. In the postshift period two groups received test trials on which the postreinforcement detention time in the first goal box (Gl) was increased. For one of these groups this increase occurred simultaneously with a reduction in Gl reward magnitude. The results indicated that for neither group did postreinforcement detention increase elevate second-alley speeds relative to those of a group which always received the longer postreinforcement detention.
