The development of memory of a conditioned response was examined in London black rats between 0 and 4 days of age. For the conditioning, a vibrotactile stimulus paired with an electric shock was presented to the animal 80 times with an interval of 2000 msec between stimuli. The animals were retested at retention intervals of 3 min or 24 hr. The results showed that 0-, 2-, 3-, and 4-day-old rats possess a retention capacity of at least 24 hr and suggest that the emergence of memory may be task-specific.
对0至4日龄的伦敦黑大鼠条件反应记忆的发展进行了研究。在条件反射实验中，将与电击配对的振动触觉刺激以每次刺激间隔2000毫秒的频率呈现给动物80次。在3分钟或24小时的保持间隔后对动物进行重新测试。结果表明，0日龄、2日龄、3日龄和4日龄的大鼠具有至少24小时的保持能力，并表明记忆的出现可能是特定任务的。
