epicritic触觉感知的滑动假设将主动移动的传感器和触摸的物体解释为摩擦系统，已知导致称为“滑动”的急动相对运动。这些滑动取决于对象的几何形状，力，材料特性和环境因素，因此，有能力将编码的感知目标，以及感知策略（传感器运动）。通过滑动传递的触觉信息将在空间和时间上不连续地编码，因为滑动有时只与接触表面的一部分接触，并且在时间上表现为离散和罕见的事件。这种不连续性可能迫使触须和指尖的触觉系统进化出特殊的方式来将触摸信号转换为触觉感受。
The slip hypothesis of epicritic tactile perception interprets actively moving sensor and touched objects as a frictional system, known to lead to jerky relative movements called ‘slips'. These slips depend on object geometry, forces, material properties, and environmental factors, and, thus, have the power to incorporate coding of the perceptual target, as well as perceptual strategies (sensor movement). Tactile information as transferred by slips will be encoded discontinuously in space and time, because slips sometimes engage only parts of the touching surfaces and appear as discrete and rare events in time. This discontinuity may have forced tactile systems of vibrissae and fingertips to evolve special ways to convert touch signals to a tactile percept.
