摘要：

目的：通过两个实验探索视野因素对伪忽视的影响，进而对相关理论进行检验。方法：实验1在速示迫选条件下使用分割点判断任务和灰度标尺任务。实验2使用灰度标尺任务和三视野速示迫选的实验方法。结果：实验1验证了在速示迫选条件下，灰度标尺的长度因素不具有反转效应，虽然影响伪忽视的程度但是不改变其方向。实验2显示，视野因素的主效应显著：当中间或右侧视野中呈现灰度标尺时，伪忽视现象存在，但是当左侧视野中呈现灰度标尺时，伪忽视现象消失。结论：结果支持空间变形是基于注意过程的理论观点。

Objective:Two experiments were performed to research the effects of visual field factor on pseudoneglect and to test the theories about neglect and pseudoneglect.Methods:Experiment 1 employed the landmark task and greyscales task in tachistoscopic and forced-choice conditions.Experiment 2 employed the greyscales task and tachistoscopic visual three-field technique.Results:Experiment 1 manifested that greyscales had no crossover effect;the length factor had effect on the greyscales task as the landmark task, but it only affected the bias magnitude, not the error direction.Experiment 2 indicated that the main effect of visual field was significant:when the greyscales were presented in the middle or right, pseudoneglect manifested, but when in the left, pseudoneglect vanished.Conclusion:The results provide evidence supporting the hypothesis that the perceptual distortion derives from the attentional process.
