Correlations (r) between dimensions of exploratory behavior and conditioned freezing

	Post-acquisition freezing	Post-extinction freezing
1. Open-field activity	.26	−.06
2. Light-zone activity	.09	−.27
3. Rearing duration	−.56*	−.10
4. Dark-zone activity	.20	−.02
5. Velocity in novel open field	.18	−.04
6. Velocity in familiar open field	.01	−.07

* Correlation is significant at the 0.05 level after Bonferroni correction
