Abstract

We have addressed the question of whether, in addition to being processed separately, colour and motion are also perceived separately. We varied continuously the colour and direction of motion of an abstract pattern of squares on a computer screen, and asked subjects to pair the colour of the pattern to its direction of motion. The results showed that subjects misbind the colour and the direction of motion because colour and motion are perceived separately and at different times, colour being perceived first. Hence the brain binds visual attributes that are perceived together, rather than ones that occur together in real time.

摘要

我们探讨了这样一个问题

颜色和运动除了被分别处理外,是否也被分别感知。我们在电脑屏幕上不断改变由方块组成的抽象图案的颜色和运动方向,并要求受试者将图案的颜色与运动方向进行配对。结果表明,受试者会错误地将颜色和运动方向进行绑定,因为颜色和运动是被分别感知的,且时间不同,颜色先被感知。因此,大脑会将一起被感知的视觉属性绑定在一起,而不是将实时同时出现的属性绑定在一起。
