There is preliminary evidence for interference between subsequently encoded velocities. We explored this effect using a motion extrapolation paradigm. In Experiments 1 and 2, moving targets disappeared behind an occluder. Participants responded at the time when they thought the target should reappear. Participants responded as if the current velocity was faster after a previous trial with a fast velocity and vice versa. In Experiment 3 the targets reappeared either on-time, early or late. A greater proportion of early trials were reported 'correct' following a fast previous trial. These experiments indicate that blending occurs between successively encoded velocity representations.
有初步证据表明后续编码的速度之间存在干扰。我们使用运动外推范式探究了这种效应。在实验1和实验2中，移动目标消失在遮挡物后面。参与者在他们认为目标应该重新出现的时间做出反应。在前一次试验速度较快之后，参与者的反应就好像当前速度更快，反之亦然。在实验3中，目标按时、提前或延迟重新出现。在前一次快速试验之后，更大比例的提前试验被报告为“正确”。这些实验表明，在连续编码的速度表征之间发生了混合。
