From: Contextual fear learning and memory differ between stress coping styles in zebrafish

Acquisition of fear memory over four conditioning trials. Freezing time (a) and erratic movement ratio (b) were measured for high stationary behavior (HSB) and low stationary behavior (LSB) fish exposed to distilled water (DI) or alarm substance (AS). Points represent mean ± 1 standard deviation. *Indicates p < 0.05 for within-treatment group comparison.
