Sergent (1982a, 1982b, 1982c) proposed that stimuli carrying high luminous energy will be better detected in the right field (left hemisphere) and stimuli carrying low energy in the left visual field (right hemisphere). A photoreceptor-based model could explain the same effects as well as several others (eccentricity effects, retinal adaptation effects). Braun, Mailloux, and Dufresne (1995) suggested that cones might favor right field stimuli and rods might favor left field stimuli. We implemented a series of near-threshold simple detection experiments comprising stimuli varying along four dimensions (color, eccentricity, duration, and size) in dark-adapted subjects. Consistent and significant right field advantages accrued for near-meridianal foveal red stimuli, but there were no field effects for eccentric blue stimuli. An alternative to Sergent's stimulus energy model and the photoreceptor-based model, namely a parvocellular-magnocellular model, is proposed.
塞尔让（1982a、1982b、1982c）提出，携带高光能的刺激在右视野（左半球）中能被更好地检测到，而携带低能量的刺激在左视野（右半球）中能被更好地检测到。一个基于光感受器的模型可以解释同样的效应以及其他几种效应（偏心率效应、视网膜适应效应）。布劳恩、马卢和迪弗雷纳（1995）提出，视锥细胞可能更倾向于右视野刺激，而视杆细胞可能更倾向于左视野刺激。我们对暗适应的受试者进行了一系列接近阈值的简单检测实验，实验中的刺激沿着四个维度（颜色、偏心率、持续时间和大小）变化。对于近子午线中央凹红色刺激，始终存在显著的右视野优势，但对于偏心蓝色刺激则没有视野效应。本文提出了一种替代塞尔让的刺激能量模型和基于光感受器模型的模型，即小细胞 - 大细胞模型。
