Post hoc analyses for all TRs showing significant differences in the hippocampus for adaptive versus maladaptive trials
| Contrast | TR |
||||
|---|---|---|---|---|---|
| 9 | 10 | 12 | 13 | 14 | |
| Adaptive > baseline mean (SE) | −1.0 (4.1) | −2.1 (3.7) | 4.6 (2.8) | 4.2 (2.1) | −0.3 (2.4) |
| Maladaptive > baseline mean (SE) | 5.5 (5.2) | 2.9 (4.1) | −5.9 (3.2) | −5.7 (3.3) | −5.2 (3.1) |
| Adaptive vs. maladaptive t test (p value) | −2.5 (0.02) | −2.6 (0.02) | 4.1 (0.001) | 3.5 (0.002) | 2.5 (0.02) |
| Adaptive vs novel t test (p value) | −1.9 (0.06) | −1.3 (0.19) | 3.7 (0.002) | 3.1 (0.006) | 1.0 (0.34) |
| Maladaptive vs novel t test (p value) | 1.15 (0.26) | 1.48 (0.15) | −1.14 (0.26) | −1.09 (0.29) | −1.28 (0.22) |
| [Adapt > maladapt] ∼ adaptive behavior r value (p value) | −0.39 (0.09) | −0.5 (0.02) | −0.12 (0.61) | −0.1 (0.68) | −0.14 (0.54) |
Reported values include the mean β-parameters for each condition against baseline, t tests between adaptive and maladaptive trials, t tests between adaptive/maladaptive versus novel trials, and regressions between β-parameters of adaptive > maladaptive and adaptive behavioral responses. For t tests, positive values represent relative enhancement signals and negative values represent relative suppression signals.
