Two experiments explored the possibility that lesions of avian hyperstriatum, which disrupt reversal learning, might have that effect through a potentiation of the influence of proactive interference. Neither experiment found any evidence to suggest excessive interference in hyperstriatal pigeons, from preceding training on a position (or color) discrimination, on retention of a color (or position) discrimination, and this was true both after a short (30 min) and after a long (6 or 7 day) retention interval. There was, however, evidence of a disturbance, not easily interpreted, in retention following the lesions. There was also convincing evidence, from both experiments, for the disruption by hyperstriatal lesions not only of reversal learning but also of tasks not involving reversals, a disruption that suggests a general tendency to perseverate in hyperstriatal birds.
破坏逆转学习的鸟类上纹状体损伤，可能通过增强前摄干扰的影响而产生这种效果。两项实验均未发现任何证据表明，在前一项位置（或颜色）辨别训练中，上纹状体受损的鸽子在颜色（或位置）辨别保持方面存在过度干扰，无论是在短（30分钟）还是长（6或7天）的保持间隔后都是如此。然而，有证据表明损伤后的保持存在一种难以解释的干扰。两项实验还都有令人信服的证据表明，上纹状体损伤不仅破坏了逆转学习，还破坏了不涉及逆转的任务，这种破坏表明上纹状体受损的鸟类普遍存在固执的倾向。
