Table 2.
Post stimulus mean regression slopes and 95% highest posterior density intervals (HPDs) for LA index, estimated from the beta regression model, as a function of both pre-stimulus LA and treatment (interaction in the model)
| Signal | Contrast | Pre-stimulus LA (slope) | Lower HPD | Upper HPD |
|---|---|---|---|---|
| Control | 1.830 | 0.437 | 3.242 | |
| Fasted-dragonfly | 0.297 | − 1.106 | 1.651 | |
| Fed-dragonfly | − 1.025 | − 2.266 | 0.107 | |
| Fasted-crayfish | − 0.366 | − 2.003 | 1.202 | |
| Fed-crayfish | 0.335 | − 1.058 | 1.687 | |
| Control—(fasted-dragonfly) | 1.518 | − 0.479 | 3.428 | |
| Control—(fed-dragonfly) | 2.865 | 1.1019 | 4.750 | |
| Control—(fasted-crayfish) | 2.189 | 0.0805 | 4.335 | |
| Control—(fed-crayfish) | 1.499 | − 0.448 | 3.488 |
Estimated contrasts with control are reported as differences in slope and relative HPDs (n = 125). Values in bold indicate significant differences from zero or from the slope of the control group
