In two experiments, pigeons with bilateral lesions of the hyperstriatum were compared with unoperated control birds on tasks designed to test an attentional account of hyperstriatal function. In both experiments, hyperstriatal lesions disrupted reversal learning but did not influence the retardation of learning associated with either nonreinforced preexposure to the to-be-conditioned stimulus (Experiment 1) or prior nondifferential reinforcement to the to-be-discriminated stimuli (Experiment 2). There was, however, evidence of an impairment in both the acquisition and maintenance of autoshaped responding in lesioned birds, an impairment which may reflect a disruption of classical associations in hyperstriatal pigeons.
在两项实验中，将双侧上纹状体受损的鸽子与未做手术的对照鸟类在旨在测试上纹状体功能的注意力解释的任务上进行了比较。在两项实验中，上纹状体损伤均干扰了逆向学习，但不影响与对即将条件化的刺激进行非强化预暴露（实验1）或对即将被区分的刺激进行先前的非差异强化（实验2）相关的学习延缓。然而，有证据表明受损鸟类在自动塑造反应的习得和维持方面均存在损伤，这种损伤可能反映了上纹状体鸽子经典联想的破坏。
