  1. Visuomotor Extrapolation.David Whitney - 2008 - Behavioral and Brain Sciences 31 (2):220-221.
    Accurate perception of moving objects would be useful; accurate visually guided action is crucial. Visual motion across the scene influences perceived object location and the trajectory of reaching movements to objects. In this commentary, I propose that the visual system assigns the position of any object based on the predominant motion present in the scene, and that this is used to guide reaching movements to compensate for delays in visuomotor processing.

  • Mental and Sensorimotor Extrapolation Fare Better Than Motion Extrapolation in the Offset Condition.Dirk Kerzel & Jochen Müsseler - 2008 - Behavioral and Brain Sciences 31 (2):206-207.
    Evidence for motion extrapolation at motion offset is scarce. In contrast, there is abundant evidence that subjects mentally extrapolate the future trajectory of weak motion signals at motion offset. Further, pointing movements overshoot at motion offset. We believe that mental and sensorimotor extrapolation is sufficient to solve the problem of perceptual latencies. Both present the advantage of being much more flexible than motion extrapolation.

  • Perception-Action as Reciprocal, Continuous, and Prospective.Jeffrey B. Wagman - 2008 - Behavioral and Brain Sciences 31 (2):219-220.
    From the perspective of ecological psychology, perception and action are not separate, linear, and mechanistic processes that refer to the immediate present. Rather, they are reciprocal and continuous and refer to the impending future. Therefore, from the perspective of ecological psychology, delays in perception and action are impossible, and delay compensation mechanisms are unnecessary.
