Grouping of encoding trials based on subsequent memory performance
| Misses | Hits: four levels of confidence | ||||
|---|---|---|---|---|---|
| Very unsure | Somewhat unsure | Somewhat sure | Very sure | ||
| Stress (n = 20) | 38.9 (2.97) | 17.24 (2.48) | 17.05 (1.36) | 14.57 (1.56) | 62.29 (4.09) |
| Control (n = 20) | 50.65 (2.97) | 14.70 (1.91) | 14.10 (0.81) | 10.70 (1.14) | 59.45 (4.22) |
| Regressors | Forgotten | Low confidence | Remembered | ||
Hits that received “very sure” confidence ratings were grouped as later remembered, and misses were grouped as later forgotten. Remaining (low confidence hit) trials were modeled as a regressor of no interest in the fMRI analysis.
