title: Differences in one-way active avoidance learning in mice of three inbred strains.
abstract: DBA/2J, C57BL/6J, and C3H/HeJ mice were given 10 one-way avoidance training trials per day, using an unconditioned stimulus intensity that provided equivalent motivation for learning to mice of all three strains, and were found to differ in their abilities to learn and retain the response. DBA/2J mice acquired the response in fewer days than did the mice of the other two strains, although C57BL/6J mice eventually reached a level of performance similar to that of DBA/2J mice. Both the rate of acquisition and the level at which avoidance performance stabilized were significantly lower in C3H/HeJ, than in DBA/2J or C57BL/6J, mice. In addition, DBA/2J mice showed a significantly greater task retention from one testing day to the next than did C57BL/6J or C3H/HeJ mice.
