Performance of the reversal learning task following maternal polyI:C and G31P treatment. (A) Trials to criterion, (B) total errors, and (C) analysis of error subtypes. sal–sal, n = 24; sal–polyI:C, n = 20; G31P–sal, n = 18; and G31P–polyI:C, n = 21. Number of litters included in testing: sal–sal = 15, sal–poly = 11, G31P–sal = 10, and G31P–poly = 11. * indicates a main effect of G31P treatment on regressive errors.
