摘要
一、问题的提出 轮廓是物体的外形线,它在视觉图形知觉中起着重要的作用。一般说来,引起轮廓的刺激,是视野中明度(或颜色)的突然变化。但是,有时在一片完全同质的视域中,人们也能看到轮廓。这种轮廓不是由于客观上的刺激梯度造成的,而是由于一系列其它因素造成的。这种轮廓叫主观轮廓,认知轮廓或错觉轮廓。
An experiment is designed to study the influence of such factors as depthcue and completion tendency on the formation of subjective contour. The figureused is adapted from G. Kanizsa. By varying the length of the broken edges ofthe triangle the guthors provide depth cues of four different levels, and foundthe subjective contour is a function of the obviousness of depth cue. From thisexperiment, authors suggested that subjective contour, in analogy to otherillusions, is dependent upon the complex interaction between a series of objectiveand subjective factors.
