Compared to saline controls, AVT significantly increases aggression while the specific V1a receptor antagonist, Manning compound, decreases aggression. Isotocin has no effect on aggression. The mean and s.e. of the per cent change in aggression from pre-tests for peptide and saline control groups are presented. Data presented are actual data; statistics run on transformed lognormal data. All marked comparisons are significantly different at p<0.05.
