Abstract:

Abstract Using the eye tracking method, we conducted two experiments to examine the OUP effects in the left (LVF) and right (RVF) fields of vision. The results show that: (1) when the OUP words presented horizontally to LVF and RVF respectlly, there was a robust facilitatory effect of early OUP for RVF presentation. The effect was absent for LVF trials, which we argue this result from the disadvantaged position of initial letters of words presented in the LVF. (2)When using the vertical stimulus presentations to investigate the OUP effects in different fields of vision, there was a marked facilitatory effect of early OUP across both visual fields, suggesting that the initial letter was advantage to the foveal, there would be the OUP effects. These findings of the research confirmed the presence of sequential processes in both left and right hemisphere when recognized the words, casting doubt on parallel models in the left hemisphere and sequential models in the right hemisphere of word processing.

摘 要 采用眼动方法，通过两个实验考察了不同视觉区域的OUP效应。结果显示：（1）当刺激材料分别平行呈现于左侧视觉区域和右侧视觉区域时，在右侧视觉区域产生了OUP效应，而在左侧视觉区域没有OUP效应，我们假设是由于左侧视觉区域首字母距离中央凹的不利位置影响了OUP效应的产生。（2）当垂直方向呈现刺激时，在两侧视觉区域均产生了明显的OUP效应，表明首字母距离中央凹处于有利位置时不会影响OUP效应的产生。实验结果支持了大脑左半球和右半球在词汇识别时的策略为系列加工，对左半球平行加工右半球系列加工的结论提出了质疑。
