无意识加工的范围和局限性是实验心理学研究中一个有争议的话题。特别是在视觉领域，广泛的范式已被用于实验性地操纵感知意识。最近的一项研究报告了连续闪光抑制（CFS）过程中的无意识数字处理，这是眼间抑制的一种强大变体，会扰乱视觉刺激的有意识感知长达数秒。由于这种距离依赖性启动效应的发现与早期显示眼间抑制消除语义处理的结果相矛盾，因此我们试图在两个实验中研究这种效应的边界条件。使用排除目标数值影响的统计分析和实验设计，我们发现了身份启动的证据，但没有 CFS 下距离依赖的数值启动确凿的证据。我们的结果表明，先前关于眼间抑制下高水平数值启动的结论可能还为时过早。 (C) 2014 Elsevier Inc. 保留所有权利。
The scope and limits of unconscious processing are a controversial topic of research in experimental psychology. Particularly within the visual domain, a wide range of paradigms have been used to experimentally manipulate perceptual awareness. A recent study reported unconscious numerical processing during continuous flash suppression (CFS), which is a powerful variant of interocular suppression and disrupts the conscious perception of visual stimuli for up to seconds. Since this finding of a distance-dependent priming effect contradicts earlier results showing that interocular suppression abolishes semantic processing, we sought to investigate the boundary conditions of this effect in two experiments. Using statistical analyses and experimental designs that precluded an effect of target numerosity, we found evidence for identity priming, but no conclusive evidence for distance-dependent numerical priming under CFS. Our results suggest that previous conclusions on high-level numerical priming under interocular suppression may have been premature. (C) 2014 Elsevier Inc. All rights reserved.
