Behavioral parameters before, during, and after learning.

<p>(a) <i>Left</i>: time changes in the correct rates for 22 individual rats (gray) were aligned to the first session that reached the criterion. The blue line indicates the mean value. <i>Right</i>: training represents data from the last 4 sessions on Day 2 in the training phase. Four sessions immediately before and 5-to-8 sessions after reaching the criterion were defined as the during-learning and post-learning periods, respectively. These periods are shown by the black bars in the left panel. The mean correct rate in the during-learning period was significantly lower than the mean correct rates in the training period and the post-learning period. Training <i>versus</i> during-learning: <i>P =</i> 9.56 × 10⁻¹⁰, <i>Q</i>_3,63 = 28.0; during-learning <i>versus</i> post-learning: <i>P =</i> 9.56 × 10⁻¹⁰, <i>Q</i>_3,63 = 24.0; <i>P =</i> 1.14 × 10⁻²⁹, <i>F</i>_2,63 = 230; Tukey's test after one-way ANOVA. (b) Same as a, but for the rates of omission trials. Training <i>versus</i> during-learning: <i>P =</i> 0.034, <i>Q</i>_3,63 = 3.62; during-learning <i>versus</i> post-learning: <i>P =</i> 6.91 × 10⁻⁴, <i>Q</i>_3,63 = 5.51; <i>P =</i> 9.12 × 10⁻⁴, <i>F</i>_2,63 = 7.84. (c) Same as a, but for the latencies to respond. Training <i>versus</i> during-learning: <i>P =</i> 0.984, <i>Q</i>_3,63 = 0.235; during-learning <i>versus</i> post-learning: <i>P =</i> 0.092, <i>Q</i>_3,63 = 3.01; <i>P =</i> 0.044, <i>F</i>_2,63 = 3.28.
