我们进行了六个实验，以了解对不同大小的流量相等的视觉刺激的简单手动反应时(RT)是受大小恒定还是受刺激所覆盖的视网膜角度的影响。我们发现，RT随着感知的刺激大小而不是视网膜角度的增加而减少，这种关系依赖于熟悉的类似3-D刺激的使用和其他大小恒定线索的可用性。因此，一种刻板印象的快速运动反应，就像在简单的RT范式中所采用的那样，受到大小恒定的调节，就像知觉判断一样。本研究结果为简单反应时与知觉之间的关系提供了原始证据。
We carried out six experiments to find out whether simple manual reaction time (RT) to flux-equated visual stimuli of different size is modulated by size constancy or by the retinal angle subtended by the stimuli. We found that RT decreased with the increase in perceived stimulus size rather than retinal angle and that this relationship depended oil the use of familiar 3-D-like stimuli and oil the availability of other size-constancy cues. Thus, a stereotyped speeded motor response, such as that employed in a simple RT paradigm, is modulated by size constancy, as is the case with perceptual judgments. The present results provide original evidence on the relationship between simple RT and perception.
