Table I.
Contrast images used to assess neural activity associated with and without spatial learning during each event.
| Event | Spatial Learning | Attempted Learning |
|---|---|---|
| Searching | A vs. B1 | B vs. C |
| Anticipation | A vs. B | B vs. C |
| Receipt of Reward | A vs. B2 | B vs. C |
| No Receipt of Reward | A vs. B2 | B vs. C |
| No Reward vs. Reward | A3 | B4 |
The following contrasts were used to identify neural activity associated with
1
spatial learning;
2
reward experience during spatial learning;
3
the effects of reward when spatial learning was possible; and
4
the effects of reward when learning was attempted but rendered impossible (e.g. reward disentangled from learning). In exploratory analyses, the A vs. C contrast was used to identify neural activity associated with the same processes as the A vs. B contrast.
