Manipulation. check measures: mean SAM unhappiness ratings and retrospective pain-US expectancy ratings (and SD) for the CSp+ and CSp− in the predictable group and the CSu1 and CSu2 in the unpredictable group.
| N = 58 | Predictable group | Unpredictable group | ||
|---|---|---|---|---|
| CSp+ | CSp− | CSu1 | CSu2 | |
| SAM unhappiness (Likert scale; 1–5) | 3.17 (0.85) | 2.17 (0.71)** | 2.55 (0.91) | 2.79 (0.77) |
| Retrospective pain-US expectancy (VAS; 0–100) | 68.66 (20.63) | 25.45 (21.09)** | 36.17 (22.05) | 53.48 (24.68)* |
*p < 0.01; **p < 0.001; for the CSp+/CSp− differences and the CSu1/CSu2 differences in the predictable and the unpredictable group respectively.
