Simulations with a single manipulandum: devaluation test phases.
| No food devalued | Second food devalued | |||||||

| A1 | A2 | A1 | A2 | |||||
| Means | 8.99 | 10.93 | t(39) = −1.01 | p = 0.317 | 24.75 | 0.45 | t(39) = 52.64 | p < 0.001 |
Number of performances of the two actions (A1 and A2) on the manipulandum, averaged over 40 replications of the simulation, are shown. Left columns refer to tests without any devaluation. Right columns refer to tests in which the food associated to A2 has been devalued.
