两个实验研究了彩绘龟的习惯化。在第一个实验中，海龟被给予背部皮层的损伤或假损伤，然后在约束上训练。尽管假损伤的海龟学会了忍受束缚，但损伤的海龟仍在与束缚作斗争，因此背侧皮层损伤破坏了对束缚的习惯。为了在第二个实验中测试对隐约出现的刺激的习惯，所有动物在手术前习惯于束缚。术后，他们继续习惯于约束。隐约可见的刺激是一个圆形的阴影，在海龟面前的屏幕上突然放大。每天给药5次，持续15天。日间或长期习惯性受损的背侧皮层病变。
Two experiments investigated habituation in painted turtles(Chrysemys picta).In the first, turtles were given lesions of the dorsal cortex or sham lesions and then trained on a restraint. Although the sham-lesioned turtles learned to tolerate the restraint, the lesioned animals continued to struggle against it. Thus dorsal cortex lesions disrupted habituation to restraint. In order to test habituation to a looming stimulus in a second experiment, all animals were habituated to the restraint before surgery. Postoperatively they continued to be habituated to the restraint. The looming stimulus was a circular shadow that enlarged suddenly on a screen in front of the turtle. It was presented 5 times per day for 15 days. Between-day or long-term habituation was impaired by dorsal cortex lesions.
