Table 2.
Comparison of the emergence of Interaction-oriented Behaviour between conditions (linear GLMM; significant differences are indicated with bold letters).
| Social test partners | Non-social test partners | ||||
|---|---|---|---|---|---|
| Unfamiliar dog | Familiar dog II | Unfamiliar object | Familiar object | ||
| Social test partners | Familiar dog I | p = 0.753 | p = 0.576 | p = 0.753 |
B ± SE = 0.457 ± 0.168 t112 = 2.791 p = 0.048 |
| Unfamiliar dog | — | p = 0.246 | p = 0.750 | p = 0.246 | |
| Familiar dog II | — | — | p = 0.750 |
B ± SE = 0.690 ± 0.162 t112 = 4.267 p < 0.001 |

| Non-social test partners | Unfamiliar object | — | — | — |
B ± SE = 0.520 ± 0.162 t112 = 3.213 p = 0.015 |
For significant explanatory variables in the final models, we provide contrast estimates (B ± SE) and t values. Familiar dog I stands for the first, Familiar dog II stands for the last trial.
