Word recognition thresholds and rapid serial visual presentation (RSVP) reading rates for both unrelated words and meaningful sentences were examined across the visual field. Both word recognition thresholds and RSVP reading rates for unrelated words can be equated across the visual field by an increase in size scale. RSVP reading rates for meaningful sentences cannot be equated across the visual field, with the fovea demonstrating a qualitative superiority over the periphery, irrespective of scale. The results suggest that the early visual machinery which underlies word recognition is the same across the visual field apart from a change in scale, whilst the periphery is qualitatively inferior to the fovea at interpreting sentences with meaning.
我们在整个视野范围内检测了无关单词和有意义句子的单词识别阈值以及快速序列视觉呈现(RSVP)阅读速度。通过增大字号,无关单词的单词识别阈值和RSVP阅读速度在整个视野范围内都可以等同。有意义句子的RSVP阅读速度在整个视野范围内无法等同,无论字号大小,中央凹在解读句子方面都表现出相对于外周的质性优势。结果表明,除了字号变化外,构成单词识别基础的早期视觉机制在整个视野范围内是相同的,而在外周解读有意义的句子时,其质性上不如中央凹。
