Reaction times to reward cues and target numbers, separated by modality
| Condition | Reward | Neutral | ||
|---|---|---|---|---|
| Trial type | Reward | Neutral | “Reward” | Neutral |
| Cues | ||||
| PET | 694 ± 142 | 766 ± 113 | 808 ± 170 | 775 ± 165 |
| fMRI | 614 ± 120 | 708 ± 110 | 784 ± 181 | 715 ± 137 |
| Targets | ||||
| PET | 454 ± 40 | 501 ± 47 | 516 ± 61 | 513 ± 59 |
| fMRI | 412 ± 30 | 454 ± 46 | 487 ± 61 | 483 ± 59 |
Mean reaction times (in ms, ±SD) are shown for the responses to cue pictures (i. e. reward-predicting and neutral scenes) and to target numbers, separately for the PET and fMRI study.
