有时两个长方形物体移动速度都很慢,从志愿者的观察角度看,就象一艘船以每秒驶过3度的距离在航行,
Sometimes they travelled much faster, at 20o a second, mimicking the way a land vehiclemoves.
有时它们都模仿陆地车辆行驶方式以每秒走过20度的距离快速移动。
The jazzy rectangles also came in different flavours. Some were low-contrast and somehigh-contrast.
长方形物体的迷彩图案也不尽相同,有些图案对比度不强烈,有些图案的对比度则很强。
The upshot, as Dr Scott-Samuel reports in the Public Library of Science, was that participantswere not fooled by slow-moving rectangles, nor by low-contrast ones.
实验结果如同Scott-Samuel 博士在公共科学图书馆报告所说,志愿者对慢速移动或图案对比度不强的物体移动速度判断较准确。
Fast-moving, high-contrast shapes, however, did befuddle them.
而对于快速移动和图案对比度强烈的物体,他们的判断常常出错。
On average, an observer reckoned that such a fast, jazzy rectangle was going 7% slowerthan was actually the case.
志愿者对于有迷彩图案和快速移动的正方形物体的速度估计要比它们的实际速度平均低了7%。
