Hole-entering response rate ordinal comparisons within individuals for the final FI session under the prediction that responding would increase across the interval.

<p>Intervals were divided into two equal duration bins, and combinations of these bins were ordinally compared. PCC values and accompanying <i>c</i>-values are displayed for individuals. Only one subject's PCC value was higher than a binomial comparison, but did not reliably differ from the randomized PCC values.</p><p>^*Subject did not complete the 20^th FI session.
