Albino guinea pigs were trained in shuttle-boxes. Superior performances were achieved with longer CS–US (15 sec. against 5 sec.) and intertrial intervals (90 sec. against 30 sec.). There were no performance increments within sessions, but improvements in performance occurred between sessions. Consolidation mechanisms probably play an important part in avoidance learning by guinea pigs.
