A technique is described for investigating word recognition involving the superimposition of 'noise' on the visual target word. For this task a word is printed in the form of letters made up of separate elements; noise consists of additional elements which serve to reduce the ease whereby the words may be recognized, and a threshold-like measure can be obtained in terms of the amount of noise. A word frequency effect was obtained for the noise task, and for words presented tachistoscopically but in conventional typography. For the tachistoscope task, however, the frequency effect depended on the method of presentation. A second study showed no effect of inspection interval on performance on the noise task. A word-frequency effect was also found in a third experiment with tachistoscopic exposure of the noise task stimuli in undegraded form. The question of whether common processes are drawn on by tasks entailing different ways of varying ease of recognition is addressed, and the suitability of different tasks for word recognition research is discussed.
本文描述了一种用于研究单词识别的技术,该技术涉及在视觉目标单词上叠加“噪声”。对于此任务,单词以由单独元素组成的字母形式打印;噪声由额外的元素组成,这些元素用于降低单词被识别的容易程度,并且可以根据噪声量获得类似阈值的度量。在噪声任务以及以传统排版方式速示呈现的单词中,均获得了词频效应。然而,对于速示镜任务,词频效应取决于呈现方法。第二项研究表明,检查间隔对噪声任务的表现没有影响。在第三项实验中,对噪声任务刺激进行未降级形式的速示曝光,也发现了词频效应。文中探讨了涉及不同改变识别难易程度方式的任务是否调用共同过程的问题,并讨论了不同任务对单词识别研究的适用性。
