The causal flows between the processes responsible for illusory contour clarity, brightness, and apparent depth in the Kanizsa square were examined. The sixty-four stimuli used consisted of all possible combinations of eight disk luminances and eight centre-to-centre separations between nearest disks. Ten subjects were instructed to rate the clarity of the illusory contour and the brightness and apparent depth differences between the Kanizsa square and its surround in each stimulus. On the basis of results obtained with the causal inference method, using partial correlations and path analysis, it is suggested that clarity of illusory contour can be influenced directly by disk separation, and that the output from the process responsible for illusory contour clarity has some effect on the processes responsible for the apparent depth and brightness differences.
研究了在卡尼萨方块中负责虚幻轮廓清晰度、亮度和表观深度的过程之间的因果流。所使用的64种刺激由八个圆盘亮度和最近圆盘之间的八个中心到中心间距的所有可能组合组成。指示十名受试者对每种刺激中虚幻轮廓的清晰度以及卡尼萨方块与其周围环境之间的亮度和表观深度差异进行评分。基于因果推断方法获得的结果，使用偏相关和路径分析，表明虚幻轮廓的清晰度可直接受圆盘间距影响，并且负责虚幻轮廓清晰度的过程的输出对负责表观深度和亮度差异的过程有一定影响。
