Between the perception of target and cursor and the construction of the signal representing the distance between them there is a delay of Τ milliseconds, so that the working perceptual signal at time t represents the target-to-cursor distance at a prior time, t – Τ. Consequently, the equation used in the model is Perceptual Control Theory (PCT) theorizes that a creature’s behaviour is varied so that their perception can reach and maintain certain fixed limits, despite external disturbances.
