Latency to perform the first nose-poke behavior (s) as a function of contingency (Paired or Yoked) and training day (PDs 14–17). To facilitate data visualization, data has been collapsed across the nature of the reinforcer (Water or 3.75 % v/v EtOH). The latter factor did not affect latencies nor significantly interacted with the remaining factors. Vertical lines represent standard errors of the mean.
