Figure 1. Social Interaction (SI): Play Fighting and SI Motivation.
Effects of ET and WC on play fighting and SI motivation in male (left) and female (right) offspring tested during pre-adolescence (P28) or mid-adolescence (P42). Bars depict group mean and T bars the standard error of the mean. N ranged from 8-12 per sex per treatment group.
A) ET groups showed reduced play fighting compared to PF or CH groups regardless of age or sex ( p<0.05). ET/WC males played less than ET/NWC males (^ p<0.05). At P28 ET/WC females also showed decreased play compared to ET/NWC females (^ p<0.05). Overall, females engaged in more play at P28 than at P42 (
p<0.05).
B) The ET/NWC female were less motivated to engage in social interaction at P42 than either the CH/NWC ( p<0.05) or the ET/WC females (^ p<0.05).
