联想序列学习模型提出，镜像系统的发展取决于相同的机制，调解巴甫洛夫和工具性条件反射的联想学习。为了测试这个模型，两个实验通过不相容的感觉运动训练来减少自动模仿，以评估镜像系统可塑性是否对偶然性敏感（即，一种表征的激活预测另一种表征的激活的程度）。在实验I中，残余自动模仿测量不兼容的训练，其中的动作刺激是一个完美的预测的反应（偶然的）或根本没有预测的反应（noncontingent）。观察到一个偶然的影响：有较少的自动模仿表明更多的学习在特遣队。实验2复制了这种偶然性效应，并表明，正如联想学习理论所预测的那样，它可以通过信号试验来消除，在这种试验中，反应发生在没有动作刺激的情况下。这些发现支持了镜像系统的发展依赖于联想学习的观点，并表明这种学习不是纯粹的赫布式的。如果这是正确的，联想学习理论可以用来解释，预测和干预镜像系统的发展。
The associative sequence learning model proposes that the development of the mirror system depends on the same mechanisms of associative learning that mediate Pavlovian and instrumental conditioning. To test this model, two experiments used the reduction of automatic imitation through incompatible sensorimotor training to assess whether mirror system plasticity is sensitive to contingency (i.e., the extent to which activation of one representation predicts activation of another). In Experiment I, residual automatic imitation was measured following incompatible training in which the action stimulus was a perfect predictor of the response (contingent) or not at all predictive of the response (noncontingent). A contingency effect was observed: There was less automatic imitation indicative of more learning in the contingent group. Experiment 2 replicated this contingency effect and showed that, as predicted by associative learning theory, it can be abolished by signaling trials in which the response occurs in the absence of an action stimulus. These findings support the view that mirror system development depends on associative learning and indicate that this learning is not purely Hebbian. If this is correct, associative learning theory could be used to explain, predict, and intervene in mirror system development.
