Predictor variables for average 20% ethanol intake consumed in an intermittent-access paradigm over nine weeks. Time spent vertical (rearing behavior) in a novel activity chamber emerged as the only significant predictor of ethanol drinking (Experiment 1, N = 23).
| Predictor Variable | Beta | P |
|---|---|---|
| Novel Locomotor: Vertical Time | 0.56 | 0.01 |
| Novel Locomotor: Horizontal Time | −0.27 | 0.22 |
| Novelty-Seeking | 0.20 | 0.31 |
| Locomotor: Vertical Time | 0.22 | 0.29 |
| Locomotor: Horizontal Time | 0.24 | 0.25 |
| Anxiety | −0.10 | 0.64 |
