图片命名中词汇频率效应的眼动研究

在延时命名范式的基础上，通过控制熟悉性并运用连续图片命名的眼动记录技术，考察图片的注视时间，将词汇提取的过程单独地呈现出来。实验结果表明，在控制熟悉性及延时命名的条件下，图片名称的频率仍影响着图片的注视时间，表现出频率效应，但对出声输出的快慢没有影响，从而进一步证实了图片命名频率效应的“词汇通达假设”。

An Eye Movement Study on Lexical Frequency Effect in Picture Naming

There were two hypotheses about lexical frequency effect in picture naming, which one was input hypothesis and the other one was lexical access hypothesis. Almeida found lexical frequency effect in a delayed picture naming task and suggested that the lexical frequency effect was a signature effect of lexical access. Because their experiment dependent variable was reaction time, the lexical access could not be separated from the output stage. In current experiment, not only familiarity of pictures was controlled, but also fixation time on picture was used to reveal lexical access in a delayed picture naming task. The result showed that the fixation time on the picture not the output stage was modulated by lexical frequency, which further confirmed the lexical access hypothesis.
