Kaleidoscopic deprivation produced effects indistinguishable from traditional light-tight patching. Here, we used a novel "kaleidoscopic" monocular deprivation that, although it rendered images fractionated and uninformative, preserved gross luminance, color, spatial frequency, motion, and contrast information, effectively sneaking the image degradation past early, feedforward mechanisms, targeting higher levels. This could be accommodated in a feedforward model of binocular combination (Meese, Georgeson, & Baker, 2006 Sperling & Ding, 2010), in which the shift reflects a (persistent) reweighting induced by an interocular gain control mechanism tasked with maintaining binocular balance (Zhou, Clavagnier, et al., 2013). Various types of deprivation-light-tight, diffuser lenses, image degradation-have been tested, and it seemed that a deprivation of contrast was necessary, and sufficient, for these shifts. Short-term monocular deprivation (∼150 min) temporarily shifts sensory eye balance in favor of the deprived eye (Lunghi, Burr, & Morrone, 2011 Zhou, Clavagnier, & Hess, 2013), opposite to classic deprivation studies (Hubel & Wiesel, 1970).
