许多人类和动物的任务被认为是由tau信息变量控制的。人们普遍认为，在减速任务（如刹车或着陆时）期间控制tau（tau）的变化率是一种常见的感知控制策略。然而，许多任务需要在减速到目标之前加速，例如达到τ理论的一个进步显示了如何使用单个动作公式来控制从启动到峰值速度的整个动作单元，并在目标处停留，具有与之前相同的感知tau信息，并解释与之前相同的减速运动学。在此，我们用蜂鸟飞向其花朵喂食器的高速视频数据来测试该理论，我们发现该理论占97%。数据中的方差，从而支持它
Many human and animal tasks are thought to be controlled with the tau informational variable It is widely accepted that controlling the rate of change of tau (tau) during decelerative tasks such as when braking or landing, is one common perceptual control strategy However many tasks require accelerating before decelerating to a goal, such as reaching An advancement of tau theory shows how a single action formula may be used to control the full action unit from initiation to peak velocity, and to rest at the goal with the same perceptual tau information as before and accounting for the same decelerative kinematics as before Here we test the theory against data from high speed video of a hummingbird flying to its flower feeder We find that the theory accounts for 97% of the variance in the data, and thus supports it
