Figure 3

(a) Number of crosses and (b) stereotypy behavior exhibited in response to challenge with 1.5 mg/kg amphetamine two days and 3 weeks after juveniles (JUV) or adults were exposed to repeated saline (SAL), 1.5 mg/kg amphetamine (1.5A), or 3.0 mg/kg amphetamine (3.0A). Data represent group means of the sum of behaviors exhibited during the final 40 minutes of a 60-min observation period, with bars depicting the standard error of the mean. In this figure, asterisks (*) indicate a significant increase in the 3.0A condition (collapsed across age) compared to the 1.5A and SAL groups (p ≤.05).
