可以通过在最大减速下的“安全”区域停止（即理想减速）所需的减速（即理想减速）来控制避免碰撞的制动，但是最大减速并未光学地指定，并且随着条件的变化而可能有所不同。当使用模拟制动任务之间操纵参与者之间的制动强度时，在制动器发作时，理想与最大减速的比率是跨组不变的，这表明校准涉及在最大减速的内在单位中对理想减速的缩放信息。当参与者内部操纵制动强度时，发现了快速重新校准的证据，并且影响制动动力学的外力的存在导致性能偏见。讨论的重点是校准，内部模型和负担能力在视觉指导作用中的作用。
Braking to avoid a collision can be controlled by keeping the deceleration required to stop (i.e., ideal deceleration) in the "safe" region below maximum deceleration, but maximum deceleration is not optically specified and can vary as conditions change. When brake strength was manipulated between participants using a simulated braking task, the ratio of ideal to maximum deceleration at brake onset was invariant across groups, suggesting that calibration involves scaling information about ideal deceleration in intrinsic units of maximum deceleration. Evidence of rapid recalibration was found when brake strength was manipulated within participants, and the presence of external forces that affect brake dynamics resulted in biases in performance. Discussion focuses on the role of calibration, internal models, and affordance perception in visually guided action.
