Abstract

Perceptual error in the Müller-Lyer and the Horizontal-Vertical illusions was quantified using nonparametric signal-detection measures of sensitivity and response bias. Sensitivity scores were positively related to signal strength with the greatest values observed for the strongest signals. Sensitivity at each signal strength did not differ between the two illusions. Response-bias scores were inversely related to signal strength, with the most conservative biases observed for the strongest signals. Response biases for each signal strength were significantly more conservative for the Horizontal-Vertical than for the Müller-Lyer illusion.

摘要

使用敏感性和反应偏差的非参数信号检测方法对缪勒-莱尔错觉和横竖错觉中的知觉误差进行了量化。敏感性分数与信号强度呈正相关，最强信号的敏感性分数最高。两种错觉在每个信号强度下的敏感性没有差异。反应偏差分数与信号强度呈负相关，最强信号的反应偏差最为保守。对于每个信号强度，横竖错觉的反应偏差比缪勒-莱尔错觉显著更保守。
