Recently, a double-anchoring theory (DAT) of lightness perception was proposed (P. Bressan, 2006), which offers explanations for all the data explained by the original anchoring theory (A. Gilchrist et al., 1999), as well as a number of additional lightness phenomena. Consequently, DAT can account for an unprecedented range of empirical results, potentially explaining everything from the basic simultaneous contrast display to subtle variations of the Gelb effect. In this comment, the authors raised 4 concerns that demonstrate serious theoretical and empirical difficulties for DAT.
最近,有人提出了一种明度感知的双锚定理论(DAT)(P. 布雷桑,2006年),该理论对原始锚定理论(A. 吉尔克里斯特等人,1999年)所解释的所有数据,以及一些额外的明度现象都提供了解释。因此,DAT能够解释前所未有的一系列实证结果,有可能解释从基本的同时对比显示到格尔布效应的细微变化等所有现象。在这篇评论中,作者们提出了4个问题,这些问题表明DAT存在严重的理论和实证困难。
