Abstract

2 EXPERIMENTS ON DIFFERENCES BETWEEN STRAINS OF HOUSE MICE IN CHARACTERISTICS RELATED TO PROCESSES OF MEMORY TRACE FORMATION ARE REPORTED. IN EXP. I, PERFORMANCES ON ACTIVE SHOCK-ESCAPE AND PASSIVE SHOCK-AVOIDANCE TASKS WERE OBSERVED UNDER MASSED AND DISTRIBUTED PRACTICE CONDITIONS; ON BOTH TASKS STRAIN DBA/2J MICE WERE SUPERIOR WHEN LEARNING TRIALS WERE MASSED, WHILE STRAIN C57BL/6J MICE WERE SUPERIOR WHEN TRIALS WERE DISTRIBUTED. IN EXP. II, IMMEDIATE POSTTRIAL ETHERIZATION FACILITATED LEARNING OF BOTH TASKS FOR STRAIN DBA/2J MICE, BUT HAD NO EFFECT ON STRAIN C57BL/6J. (25 REF.)
