Overview of the parametric modulator calculations used for estimating brain activation
| Number of symbols shown | RP | RPE in case of win (1): RPE = 1 − RP | RPE in case of no win (0): RPE = 0 − RP | |
|---|---|---|---|---|
| Win domain | 1 | 1 | 1 − 1 = 0 | 0 − 1 = −1 |
| 2 | 1/2 | 1 − 1/2 = 1/2 | 0 − 1/2 = −1/2 | |
| 3 | 1/3 | 1 − 1/3 = 2/3 | 0 − 1/3 = −1/3 | |
| 4 | 1/4 | 1 − 1/4 = 3/4 | 0 − 1/4 = −1/4 | |
| Number of symbols shown | LP | LPE in case of loss: LPE = −1 − LP | LPE in case of no loss: LPE = 0 − LP | |
| Loss domain | 1 | 0 | −1 − 0 = −1 | 0 − 0 = 0 |
| 2 | −1/2 | −1 − (−1/2) = −1/2 | 0 − (−1/2) = 1/2 | |
| 3 | −2/3 | −1 − (-2/3) = −1/3 | 0 − (−2/3) = 2/3 | |
| 4 | −3/4 | −1 − (−3/4) = −1/4 | 0 − (−3/4) = 3/4 |
