【摘要】 通过两个实验探索视野因素对伪忽视(pseudoneglect)的影响。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(crossover effect),虽然影响伪忽视的程度但是不改变其方向。实验2使用了灰度标尺任务和三视野速示迫选的实验方法研究了视野和操作用手因素对伪忽视的影响。方差分析显示,操作用手因素没有显著的主效应,而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,伪忽视现象仍然存在,但是当左侧视野中呈现灰度标尺时,伪忽视现象消失。该结果为多数研究者所持的空间变形是基于注意过程的理论观点提供了实验证据的支持。讨论部分将Anderson(1996)提出的注意的右半球优势理论的数学化模型稍作修正,并与空间变形理论相结合,首次将空间变形理论引入对伪忽视机制的解释。更多还原

【Abstract】 Two experiments were performed to research the effects of visual field factor on pseudoneglect. Tachistoscopic and forced-choice methods were employed in experiment 1. The results replicated the crossover effect in landmark task as before, and manifested that greyscales have no crossover effect—the length factor have effect on the greyscales task as the landmark task, it only affects the bias magnitude, but not the error direction. Experiment 2 employed the greyscales task and tachistoscopic visual three-field technique to examine the effects of both visual field and hand used factors. The results indicated that the factor of hand used had no significant main effect, but the main effect of visual field was significant: when the greyscales were presented in the middle or right, pseudoneglect still manifested, but when in the left, pseudoneglect vanished. The results provided evidence supporting the hypothesis that the perceptual distortion derives from the attentional process. The authors modified the mathematical model of attentional predominance of right hemisphere proposed by Anderson(1996) and combined it with the size distortion theory to explain the pseudoneglect phenomena for the first time.更多还原
