| 摘 要： | 本研究探讨宽带宽噪音图片的反倾斜效应及短期训练对其影响。首先,我们测量被试对四个朝向(0°,45°,90°和135°)噪音图片的知觉明显度阈值。然后根据被试的阈值生成图片,让被试完成朝向辨识任务,记录正确率和反应时。结果表明人对倾斜朝向刺激的辨识显著好于主要朝向。并且,被试对所有朝向刺激的辨识经训练后都有显著提高。本研究提示人们对于这种宽带宽噪音图片的辨识能够学习,但是短期的训练不能使反倾斜效应消失。

| Abstract: | Evidence has accumulated for over a century that the visual system of humans and many other animals is more sensitive to contour stimulation at vertical or horizontal orientations than to stimulation at the oblique orientations,which is termed as anoblique effect.But this effect changes when the visual stimuli are broad-band noise images.The present study investigated the inverse oblique effect of broad-band noise stimuli and the short-term training on this effect.Broad-band noise stimuli are images with mo... |
