The maze–feeder-interaction model yielded the smallest AIC.
| Models | AIC | Estimated coefficients of variables | ||||
|---|---|---|---|---|---|---|
| δ0 (Intercept) | δ1 (Maze) | δ2 (Feeder) | δ3 (Maze:feeder) | |||
| 1 | [δ0, δ1, δ2, δ3] | 1640 | 8.41344 | −0.34862 | −0.07784 | 0.04685 |

AICs for running distance (Experiment 3). AICs and estimated coefficients of variables were calculated for five models designed for running distance in Experiment 3. The model [δ0, δ1, δ2, δ3] indicates that maze, feeder and their interaction had significant effects.
Single: X = 8.06482 + (−0.03099 + ris) × feeder + rii.
Paired: X = 8.41344 + (−0.07784 + ris) × feeder + rii.
