Ontogenetic development of active avoidance learning, extinction and retention was studied in rats. The learning of a 1-way active avoidance was most rapid between Weeks 4 and 6, although some slight gender-related differences were evident. No such unambiguous development was detected in forced extinction. The 24-hr retention of avoidance peaked at the age of 4 weeks whereas 1-month retention was best in animals trained at the age of 8 weeks. The retrieval of memory trace also had best values at these ages. Retention of forced extinction was found to peak in 6-week animals. The existence of developmental "critical periods" must be considered cautiously as various functions have different time courses depending upon the chosen parameters in assessment.
研究了大鼠主动回避学习、消退和记忆保持的个体发生发展。单向主动回避学习在第4周和第6周之间最为迅速，尽管存在一些与性别相关的细微差异。在强迫消退中未检测到如此明确的发展情况。回避行为的24小时记忆保持在4周龄时达到峰值，而1个月的记忆保持在8周龄训练的动物中最佳。记忆痕迹的提取在这些年龄时也具有最佳值。强迫消退的记忆保持在6周龄的动物中达到峰值。必须谨慎考虑发育“关键期”的存在，因为根据评估中选择的参数，各种功能具有不同的时间进程。
