Subjective intensity rating to conditioning stimuli (−/100)
| Conditions | Baseline (mean ± SD) | With stimuli (mean ± SD) | P |
|---|---|---|---|
| Visual |
0 ± 0 |
59.0 ± 24.1 |
< 0.001 |
| Auditory |
18.8 ± 15.0 |
65.6 ± 24.1 |
< 0.001 |
| Gustatory |
6.6 ± 4.4 |
40.3 ± 17.3 |
< 0.001 |
| Multisensory | 7.5 ± 4.9 | 47.3 ± 22.8 | < 0.001 |
Subjective rating to conditioning stimuli was assessed by numerical scale, in which “0 = no stimulus could be detected” to “100 = the strongest stimulus imaginable”. The comparisons between the conditions with stimuli and corresponding baseline were investigated by paired t-test.
