Table 1. Response rates and discrimination ratios for each of the final 4 days of baseline training for each rat. Mean data for the final 4 days is located to the right of the training data. Note that for Rat O-3 there was an equipment malfunction on day 231. Data from day 231, therefore, were omitted from the Table and the rat was run for an additional day before being tested (day 232).
