摘要

高效视觉处理的一个重要方面是利用当前和先前的信息来预测我们接下来会看到什么。在自然观看和观察文字时,通常在我们将视线移向感兴趣的物体或文字之前,视野外区域就会显示出即将出现的视觉信息。这种 "预览效应 "已在文字阅读文献中研究了多年,最近又在物体感知中得到了研究。在这里,我们综合了单词识别和物体感知的方法来研究预览时间对单词识别神经测量的影响。通过结合使用脑电图和眼动跟踪,一组多语言参与者参加了一个凝视条件下的单次囊状移动实验,在该实验中,单词出现在他们的视网膜旁视野中。在有效预览试验中,预览期间和囊回之后出现的是同一个单词;而在无效条件下,囊回目标是一个数字串,在囊回过程中变成了一个单词。正如假设的那样,有效预览大大减少了与固定相关的诱发反应。有趣的是,多变量解码分析显示,预览效应比之前报道的单词预览效应要早得多,而且个体解码表现与参与者的阅读分数相关。这些结果表明,视网膜旁预览可以影响相对较早的累积后文字处理,并有助于解决文字和对象文献之间的一些差异。

An early effect of the parafoveal preview on post-saccadic processing of English words.

An early effect of the parafoveal preview on post-saccadic processing of English words.

A key aspect of efficient visual processing is to use current and previous information to make predictions about what we will see next. In natural viewing, and when looking at words, there is typically an indication of forthcoming visual information from extrafoveal areas of the visual field before we make an eye movement to an object or word of interest. This "preview effect" has been studied for many years in the word reading literature and, more recently, in object perception. Here, we integrated methods from word recognition and object perception to investigate the timing of the preview on neural measures of word recognition. Through a combined use of EEG and eye-tracking, a group of multilingual participants took part in a gaze-contingent, single-shot saccade experiment in which words appeared in their parafoveal visual field. In valid preview trials, the same word was presented during the preview and after the saccade, while in the invalid condition, the saccade target was a number string that turned into a word during the saccade. As hypothesized, the valid preview greatly reduced the fixation-related evoked response. Interestingly, multivariate decoding analyses revealed much earlier preview effects than previously reported for words, and individual decoding performance correlated with participant reading scores. These results demonstrate that a parafoveal preview can influence relatively early aspects of post-saccadic word processing and help to resolve some discrepancies between the word and object literatures.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
