Using quantitative psychophysical measurements, the effects of luminance contrast(LC) and equiluminance color contrast (ECC) between components of illusory figureson the magnitudes of orientation illusion (Zoellner illusion), length illusion (Muller-Lyer illusion and Ponzo illusion) and area illusion (Delboeuf illusion) were investigated.The results showed that, compared with normal illusory magnitude, the illusory magni-tude of the subjects decreased obviously when LC or ECC existed between the compo-nents...

Using quantitative psychophysical measurements, the effects of luminance contrast(LC) and equiluminance color contrast (ECC) between components of illusory figureson the magnitudes of orientation illusion (Zoellner illusion), length illusion (Muller-Lyer illusion and Ponzo illusion) and area illusion (Delboeuf illusion) were investigated.The results showed that, compared with normal illusory magnitude, the illusory magni-tude of the subjects decreased obviously when LC or ECC existed between the compo-nents of the illusory figures. The decrease was especially obvious in the orientation illu-sion. The minimum contrasts for inducing contour and border illusions were only1.8% and 5.3% under LC. They increased to 66.0% and 46.4% respectively whenboth luminance and color contrasts were introduced into the figures. These observationsprovided evidence for the existence of mutual inhibition between the luminance, colorand form channels of the visual system.

用定量的心理物理测量方法,研究了错觉图形组成成分间的亮度对比和颜色对比对方位错觉(Zoellner错觉)、长度错觉(Muller-Lyer错觉和Ponzo错觉)及面积错觉(Delboeuf错觉)幅度的影响。测试结果表明:与通常的错觉效应相比,当错觉图形组成成分间存在亮度对比或颜色对比(等亮度)时,受试者的错觉程度明显降低;其中,当存在颜色对比时,方位错觉的下降幅度更为显著,达到69.3%。此外还观察到,在单纯亮度对比条件下,只需1.8%和5.3%的低对比度即可分别产生轮廓和边缘错觉;但在等亮度颜色对比时这种错觉完全消失;而且,当存在颜色对比时,即使把错觉图形与背景间不同颜色的对比度增加到46.4%和66.0%,仍不能产生明显的边缘和轮廓错觉。这些实验结果提示:在视觉系统中,传递长度、大小、方位和边缘等图形特征的视觉通道与传递亮度和颜色特征的视觉通道之间可能存在着相互抑制作用。

The depth perception in random-dot stereograms (RDS) was investigated under two different display conditions: equiluminance with chromaticity contrast and heteroluminance without chromaticity contrast. The main results were: (1) RDSs were found to induce depth equally well under both display modes; (2)The disparity threshold for perceiving depth in isochromatic RDSs reached its minimum and leveled off at a luminance contrast of 30%, with larger disparities, depth was perceived down to about 10% contrast;(3)...

The depth perception in random-dot stereograms (RDS) was investigated under two different display conditions: equiluminance with chromaticity contrast and heteroluminance without chromaticity contrast. The main results were: (1) RDSs were found to induce depth equally well under both display modes; (2)The disparity threshold for perceiving depth in isochromatic RDSs reached its minimum and leveled off at a luminance contrast of 30%, with larger disparities, depth was perceived down to about 10% contrast;(3) When the two eyes were stimulated with chromaticity RDSs, but with different color contrast, the disparity threshold was not significantly different from that with heteroluminance RDSs; (4) Under the condition that one eye was stimulated with chromaticity RDS and the other with heteroluminance RDS, the observers could perceive depth only when contrast of the chromaticity RDS was substantially above equiluminance. The findings suggested that stereoscopic depth is mediated by both the magnocellular and parvocellular (blob and interblob) systems.

研究了在亮度对比与等亮度颜色对比的条件下,受试者分辨随机点阵立体图对的立体视敏度(最小视差).结果表明:(1)在亮度对比条件下,立体视敏度随对比度的增加而增加,10%的对比度即可引起立体视知觉,对比度大于30%时达到饱和;(2)在亮度对比与等亮度颜色对比两种不同的条件下,受试者的立体视敏度不存在有统计学意义的差异;(3)当双眼分别接受不同颜色的等亮度立体图刺激时,与亮度对比条件相比,受试者的立体视敏度无明显差异;(4)当受试者双眼分别接受由亮度对比和颜色对比形成的立体图刺激时,只有当颜色对比图中图形与背景间的对比度超过等亮度值38%以上时,才能形成立体视知觉.以上结果提示,大、小细胞系统(包括斑点系统与斑点间系统)均参与立体视知觉信息的传递.
