摘要： 本实验以被试的反应时为指标,用速示器呈现实验刺激,通过系统改变诱导区域的面积和反射率对主观轮廓知觉进行了研究。实验结果表明:随着主观轮廓图形诱导面积的减小和诱导部分反射率的增加,明度对比减弱,被试的反应时增加,并且各反应时之间存在显著差异。这表明诱导部分的面积和反射率都以明度对比为中介引起了主观轮廓知觉的系统改变。这说明视觉系统中侧抑制引起的明度对比在主观轮廓知觉中起重要作用。

Abstract: Using the reaction time as the indicator and presenting the stimuli ina tachistoscope, these experiments changed systemically the area and refle-ctance of the inducing fields. The purpose was to investigate the perceptionof subjective contours. The results showed that the subject's reaction timeincreased with the decrease of the area and the increase of the reflectan-ce of the inducing field. The difference was very significant among thereaction times. These demonstrate that the area and reflectance of the in-ducing fields cause a systematic change of the subjective contour, mediatedby brightness contrast. This suggests that the brightness contrast producedby the lateral inhibition in the visual system plays a very important rolein the perception of subjective contours.
