眼睑运动的可能性，大小和速度被认为是协变在收购和表达的条件反射在兔子（Oryctolagus cuniculus），并普遍接受的条件刺激（CS）激活的关联强度的互换措施。为了验证这一假设，作者研究了这些眼睑运动测量中的协变模式，以及上眼睑和瞬膜中的采集和刺激泛化。而不是这些措施之间的预期的协变，眼睑运动幅度在CS分布在近似双峰的方式。也就是说，眼睑活动主要由非常小的（< 0.125 mm）基线测量值和较大（> 1 mm）运动的混合物组成。结果进行了讨论相对于他们的影响实时模型的眼睑调理。
The likelihood, size, and speed of eyelid movements are thought to covary during the acquisition and expression of conditioning in rabbits (Oryctolagus cuniculus) and are generally accepted as interchangeable measures of the associative strength activated by the conditioned stimulus (CS). To test this assumption, the authors examined the patterns of covariation in these eyelid movement measures in acquisition and stimulus generalization in the upper eyelid and nictitating membrane. Rather than the expected covariation among these measures, eyelid movement magnitudes during the CS were distributed in approximately a bimodal manner. That is, eyelid activity consisted largely of a mixture of very small (< 0.125 mm) baseline measurements and larger (> 1 mm) movements. The results are discussed with respect to their implications for real-time models of eyelid conditioning.
