Results of corticosterone reactivity for prenatal stress by rearing conditions. There was a significant effect of rearing for voles that were prenatally stressed; prenatally stressed voles cross-fostered to high-contact parents displayed the least corticosterone reactivity but the most when cross-fostered to low-contact parents. There was no effect of either high- or low-contact parents for voles in the control condition. Error bars represent standard errors of the mean. The asterisks indicate a significant difference between rearing conditions (p < .01).
