Figure 1. Behavior in the locomotor chamber.
A) There was a main effect of housing condition on total distance travelled (p < 0.001). Isolated animals travelled the greatest distance in one hour, followed by paired and then enriched animals. B) There was a main effect of housing condition on the measure of horizontal activity (p < 0.001). Isolated animals had the highest number of broken beams in the horizontal plane, followed by paired, and then enriched animals. C) Enriched animals had significantly lower expression of stereotypical behavior than paired or isolated animals (p < 0.001). Paired and isolated animals were not significantly different from each other.
