摘要
采用调节法考察了四种版本Ponzo错觉量,来检验倾斜恒常性这一解释Ponzo错觉的新理论。实验一发现,对称Ponzo错觉变异版本在水平线间距85mm和120mm时得到了较多的错觉量;实验二发现,不对称Ponzo错觉只有在水平线间距50mm时的错觉量符合倾斜恒常性理论。实验结果表明图形背景线、水平线间距和视角因素都是产生Ponzo错觉的重要因素,而倾斜恒常性理论过分强调了背景线的倾斜诱导效应,忽略了其他结构因素对Ponzo错觉的影响,故在解释Ponzo错觉时存在局限性。
Tilt constancy theory is a new but limited theory that explains Ponzo illusion. The theory claims that the tilt induction effect of tilt background line made the subjects have the different perception of two horizontal lines. But other researchers have different opinions from the Prinzmental＇s results. All of the disputes seemed to reflect the limitation inherent in the theory. The method of adjustment was employed. In the experiments,the fixed design 2 （viewpoints： 6°,2°） × 2 （illusion versions： standard,rectilinear） × 2 （distances of horizontal lines： 50mm,85mm and120mm） was used. The subjects were asked to adjust the distances of horizontal lines below by using the ＂PgDn＂or ＂PgUp＂key until they thought the distances of horizontallines below equaled the ones above. AVOVA was employed to analyze the figures calculated by the illusion magnitude formula. In Experiment1,the illusion magnitude of the symmetrical rectilinear version of Ponzo illusion was obtained,which is the same as Prinzmetal （2001） got when the distance of horizontal line was set to 50mm. However,under the condition of 85mm and120mm,we got more magnitude of illusion than that of the previous results; the different results did not support the tilt constancy theory. In Experiment 2,the illusion magnitude of the asymmetrical rectilinear version of Ponzo illusion was obtained,which is the same as Prinzmetal （2001） got when the distance of horizontal line was set to 50mm. However,under the condition of 85mm and120mm,we got more magnitude of illusion than that of the 50mm,and all of the illusion magnitudes of the asymmetrical rectilinear version of Ponzo illusion did not match well with the asymmetrical standard version. Namely,only when the distance of horizontal line was 50 mm did the result confirm the theory. The results from the research suggested： （1） The results from the Prizmental research may be obtainable only in specific conditions. （2） The Tilt Constancy theory had its limitations. It failed
