Cumulative difference scores in the reinforcer devaluation task
| Monkey | Saline | MUS before satiation | MUS after satiation |
|---|---|---|---|
| SA | 11 | 0 | 0 |
| SV | 22 | 15 | 1 |
| OT | 27 | 6 | 8 |
| TR | 13 | 0 | 5 |
| Mean | 18 | 5* | 4* |
Difference scores represent the number of objects associated with the devalued (sated) food the monkey chose in each probe session following devaluation subtracted from the number of objects associated with the same food chosen in the preceding baseline probe session. Difference scores are presented for each experimental condition: saline infusions, MUS before satiation, and MUS after satiation.
↵*Significant difference (p < 0.05) compared with saline infusion.
