In tachistoscopic studies requiring "same/different" judgements on pairs of stimuli, differences between unilateral and bilateral presentation have been interpreted in terms of higher level cognitive processing. However, unilateral presentation is usually confounded with vertical and bilateral presentation with horizontal arrangement of stimuli. The effect of various stimulus arrangements was examined in two experiments. The results gave no evidence for an independent effect of uni- vs bilateral presentation, but rather a strong effect of the spatial arrangement such that pairs arranged on a straight line through the fixation point yield faster reaction times than any other vertical or horizontal arrangement.
在需要对成对刺激做出“相同/不同”判断的速示研究中，单侧呈现和双侧呈现之间的差异已根据更高层次的认知加工来解释。然而，单侧呈现通常与垂直呈现混淆，而双侧呈现则是刺激水平排列。在两个实验中检验了各种刺激排列的效果。结果没有证据表明单侧呈现与双侧呈现具有独立的效果，而是空间排列有很强的效果，即通过注视点呈直线排列的刺激对产生的反应时间比任何其他垂直或水平排列都要快。
