This experiment investigated the differential sensitivity of various areas of the retina using flicker. For 12 subjects testing was carried out in the fovea, and 5 degrees and 6 degrees temporal to the fovea using a wavelength of 555 nm. Testing was done both in the presence of a surround beam and in its absence. In all cases, there was a 2.5- to 4-fold increase in the amount of energy needed to perceive flicker as testing was shifted from the fovea to the periphery. A number of possible explanations are suggested to account for these findings.
本实验使用闪烁光研究了视网膜不同区域的差异敏感性。对12名受试者在中央凹以及中央凹颞侧5度和6度处进行测试，使用波长为555纳米的光。测试分别在有环绕光束和无环绕光束的情况下进行。在所有情况下，当测试从中央凹移向周边时，感知闪烁所需的能量增加了2.5至4倍。针对这些发现提出了一些可能的解释。
