The purpose of this study was to investigate whether information about the acceleration characteristics of a moving target can be used for both action and perception. Also of interest was whether prior movement experience altered perceptual judgements. Participants manually intercepted targets moving with various acceleration, velocity and movement time characteristics. They also made perceptual judgements about the acceleration characteristics of these targets either with or without prior manual interception experience. Results showed that while aiming kinematics were sensitive to the acceleration characteristics of the target, participants were only able to perceptually discriminate the velocity characteristics of target motion, even after performing interceptive actions to the same targets. These results are discussed in terms of a two channel (action-perception) model of visuomotor control.
本研究的目的是调查关于移动目标加速度特征的信息是否可用于行动和感知。另一个感兴趣的问题是先前的运动经验是否会改变感知判断。参与者手动拦截以各种加速度、速度和运动时间特征移动的目标。他们还在有或没有先前手动拦截经验的情况下，对这些目标的加速度特征进行感知判断。结果表明，虽然瞄准运动学对目标的加速度特征敏感，但参与者即使在对相同目标执行拦截动作后，也只能在感知上区分目标运动的速度特征。本文根据视觉运动控制的双通道（行动 - 感知）模型对这些结果进行了讨论。
