(A) Prenatal exposure to ethanol decreased play fighting in both younger and older animals. DHA administration improved this behavior back to control levels. Younger animals play fought significantly more than older animals. (B) Time spent sniffing was not significantly affected by prenatal ethanol exposure, but was higher in younger animals than older animals. (C) Younger animals also spent more time chasing than older animals. At 28 days of age, DHA-treated animals spent more time chasing than NTC pups. No effects were seen in 42-day-old animals. (D) Social motivation was not significantly affected by prenatal ethanol exposure or postnatal treatment.
Data are mean of 10–14 animals per group (see Table 2). T–bars are the standard error of the mean. *significantly (p<0.05) different to Ch (all), PF (all), and Et-DHA. # significantly (p<0.05) different to P28. & significantly (p<0.05) different to Ch (all) at same age. @ all DHA significantly (p<0.05) different to all NTC.
