在两个实验中，当参与者按照口头指示用电脑鼠标点击和移动图片时，他们的眼球运动被监控。在实验1中，一张参考图片（如一张长凳的图片）和三张图片一起被呈现，其中两张图片的名字与参考图片的名字有相同的初始音素（如床和铃铛）。参与者更倾向于关注频率较高的图片（床），而不是频率较低的图片（钟）。在实验2中，参考图片与三个不相关的干扰物同时呈现。对高频名称所指的注视潜伏期比低频名称所指的注视潜伏期短。在33毫秒的时间片上分析注视物与参照物和干扰物的比例，以提供频率效应的时间过程的细粒度信息。这些分析表明，频率影响词汇获取的最早时刻，并排除了频率的迟发性、决策偏差位点。使用频率影响静息激活水平、连接强度和激活后决策偏差的模型进行模拟，进一步限制了频率效应的轨迹。(C) 2001学术出版社。
In two experiments, eye movements were monitored as participants followed spoken instructions to click on and move pictures with a computer mouse. In Experiment 1, a referent picture (e.g., the picture of a bench) was presented along with three pictures, two of which had names that shared the same initial phonemes as the name of the referent (e.g., bed and bell). Participants were more likely to fixate the picture with the higher frequency name (bed) than the picture with the lower frequency name (bell). In Experiment 2, referent pictures were presented with three unrelated distracters. Fixation latencies to referents with high-frequency names were shorter than those to referents with low-frequency names. The proportion of fixations to the referents and distracters were analyzed in 33-ms time slices to provide fine-grained information about the time course of frequency effects. These analyses established that frequency affects the earliest moments of lexical access and rule out a late-acting, decision-bias locus for frequency. Simulations using models in which frequency operates on resting-activation levels, on connection strengths, and as a postactivation decision bias provided further constraints on the locus of frequency effects.
