在孵化后的第一天，分别用印迹刺激训练20分钟、60分钟、120分钟和240分钟。第二天，他们都接受了60分钟的再培训。雏鸡第一天的经验越丰富，第二天前脑顶前部大分子中氚化尿嘧啶的掺入率越低。在其他大脑区域没有发现这种效果，在第一天接受类似治疗但第二天没有再训练的小鸡的大脑区域也没有发现这种效果。
On the first day after hatching, domestic chicks were trained for 20, 60, 120, or 240 minutes with an imprinting stimulus. On the second day, they were all retrained for 60 minutes. The greater the chicks' experience on the first day, the lower the rate of incorporation of tritiated uracil into macromolecules in the anterior part of the forebrain roof on the second day. Such effects were not found in other brain regions, nor in any brain region of chicks that received similar treatment on the first day but were not retrained on the second.
