This study evaluated the brain activation state during error making in youth with mild spastic cerebral palsy and a peer control group while carrying out a stimulus recognition task. The key question was whether patients were detecting their own errors and subsequently improving their performance in a future trial. Findings indicated that error responses of the group with cerebral palsy were associated with weak motor preparation, as indexed by the amplitude of the late contingent negative variation. However, patients were detecting their errors as indexed by the amplitude of the response-locked negativity and thus improved their performance in a future trial. Findings suggest that the consequence of error making on future performance is intact in a sample of youth with mild spastic cerebral palsy. Because the study group is small, the present findings need replication using a larger sample.
本研究评估了轻度痉挛型脑瘫青年患者及其同龄对照组在执行刺激识别任务时犯错期间的大脑激活状态。关键问题在于患者是否能察觉到自身错误，并随后在未来的试验中提高其表现。研究结果表明，脑瘫组的错误反应与较弱的运动准备相关，这通过晚期继时性负变化的幅度来衡量。然而，患者能够察觉到自身错误，这通过反应锁定负波的幅度来体现，因此他们在未来的试验中提高了表现。研究结果表明，在轻度痉挛型脑瘫青年样本中，犯错对未来表现的影响依然存在。由于研究样本较小，目前的研究结果需要使用更大的样本进行重复验证。
