Comparison of retention and retraining tests
| Time after training (min) | t (LIcorM ≠′ LIcorV) | αR (LIM ≠′ LIV) | Overlapping of confidence intervals for LInpr |
|---|---|---|---|
| 0 | 0.04 | 0.514 | yes |
| 15 | 3.41* | 0.044 | no |
| 30 | −0.18 | 0.588 | yes |
| 60 | 3.80* | 0.004 | no |
| 180 | 2.64* | 0.019 | yes |
Results of two-tailed joint t- and randomization tests for the null hypothesis that the LIs at a given time after training do not differ in tests with mated (LIM and LIcorM) and virgin (LIV and LIcorV) females. (*)Differences significant at α = 0.05 according to the t-test. The fourth column is a summary of those cases where there is an overlap of 95% confidence intervals for LInpr.
