It has been claimed that the recognition of words displayed in isolation is affected by the precise location at which they are fixated. However, this putative role for fixation location has yet to be reconciled with the finding from reading research that binocular fixations are often misaligned and, therefore, more than 1 location in a word is often fixated simultaneously. The accuracy and alignment of binocular fixations during single word processing have not been assessed previously. To investigate this issue, words were presented for lexical decision at locations around a central fixation point. Eye-tracking data revealed that participants often fixated inaccurately and that fixations were frequently misaligned, but that this did not affect word recognition. The findings show that binocular fixation disparity is pervasive even in single word displays and a potential source of confound for research into effects of fixation location on word recognition.
有人声称，孤立显示的单词的识别受到注视点精确位置的影响。然而，这种注视点位置的假定作用尚未与阅读研究的发现相协调，即双眼注视通常是不对准的，因此，一个单词通常同时注视多个位置。在单个单词处理过程中，双眼注视的准确性和对准性以前没有得到评估。为了研究这个问题，单词在中央注视点周围的位置呈现进行词汇判断。眼动追踪数据显示，参与者经常不准确地注视，并且注视经常不对准，但这并不影响单词识别。研究结果表明，即使在单个单词显示中，双眼注视视差也很普遍，并且是注视位置对单词识别影响的潜在混淆源。
