| Total trials | 359.2 ± 49.5 | 227.2 ± 31.5 | 413.6 ± 1129 |
| Total errors | 113.5 ± 18.9 | 69.8 ± 13.8 | 124.5 ± 35.0 |
| Total correction errors | 255.3 ± 46.5 | 175.5 ± 39.7 | 288.0 ± 63.5 |
| Total trials omitted | 13.3 ± 3.6 | 8.8 ± 4.3 | 6.0 ± 2.1 |
| Average stimulus reaction time (s) | 6.5 ± 0.5 | 7.7 ± 1.6 | 5.1 ± 0.5 |

Genotypes did not significantly differ in autoshaping, pretraining, or discrimination performance. n = 8–12 per genotype. Data are means ± standard errors of the mean.
