A unidirectional selective breeding experiment performed over six generations resulted in a line of mice (S 6 ), which differed from the maintained unselected Swiss albino strain, called normal (N) strain, in the following respects: S 6 mice increased their open field activity after maze learning significantly more than N mice. S 6 mice ambulated more and exhibited more thigmotactic behaviour in a circular open field than N mice. S 6 mice were superior than N mice in regard to maze learning capacity. Finally, S 6 mice were interpreted as significantly less emotional according to their defecation, more responsive to novelty according to their urine pattern and more aggressive than N mice.
