Selective breeding of rat strains showing high and low avoidance behavior in the shuttlebox test has been performed since 1985. To elucidate the postnatal behavior of the high and low avoidance strains, animals from both lines were subjected to an open‐field test, wheel cage activity test and Biel maze test in the 13th, 14th and 16th generations, respectively. No significant differences in any parameter in the open‐field test were observed between high and low avoidance lines. However, animals from the high avoidance line showed higher motor activity in the wheel cage and fewer errors in the Biel maze than the low avoidance line.
