本研究调查了等光体的颜色变化是否会突然出现，这表明它可以并行地预先注意到。实验1的结果表明，在等亮度背景上呈现的突然颜色变化不会突出。但是，当颜色变化伴随着微小的亮度变化时，它确实会弹出。实验2的结果表明，跳出完全是由于亮度的变化而不是颜色的变化。实验3和实验4的结果表明，未能找到等亮度的突出物不能归因于对彩色刺激的有限的时间分辨率。实验5的结果表明，特定的搜索策略不能对获得的结果负责。这一结果与有关Parvo和Magno系统的生理学结果是一致的。
The present studies investigated whether an isoluminant color change pops out, indicating that it can be detected preattentively in parallel. The results of Experiment 1 show that an abrupt color change presented on an equiluminant background does not pop out. However, when the color change is accompanied by a small luminance change, it does pop out. The results of Experiment 2 show that the pop-out is fully due to the luminance change and not to the color change. The results of Experiments 3 and 4 show that the failure to find a pop-out at equiluminance cannot be attributed to the limited temporal resolution for chromatic stimuli. The results of Experiment 5 show that particular search strategies cannot be responsible for the obtained results. The results are in agreement with physiological findings regarding the parvo and magno systems.
