We investigated whether the position of the eyebrows influences the perceived shape of the eyes by employing psychophysical measurements. Experiment 1 used arched and straight eyebrows at five different inclinations as stimuli and measured the perceived inclination of the eyes. The results demonstrated that the eyes are perceived to be somewhat inclined in the same direction as the eyebrows. Experiment 2 measured the perceived eye size by manipulating the distance between the eyes and the eyebrows and the curvature of the eyebrows across three levels. The results showed that the lower eyebrows (ie closer to eyes) made the eyes appear larger and the higher eyebrows made the eyes appear smaller, while eyebrow curvature had no effect on perceived eye size. Experiment 3 examined the role of the eye-eyebrow distance in the eye inclination illusion shown in experiment 1. The eye inclination illusion was unaffected by the eye-eyebrow distance, suggesting that the eye inclination illusion and the eye size illusion may involve different kinds of assimilation. These illusions are discussed in terms of face perception and possible practical applications.
我们通过心理物理学测量方法研究了眉毛的位置是否会影响眼睛的感知形状。实验1使用了五种不同倾斜度的拱形和直线形眉毛作为刺激物，并测量了眼睛的感知倾斜度。结果表明，眼睛被感知为与眉毛的倾斜方向相同。实验2通过操纵眼睛与眉毛之间的距离以及眉毛的曲率，在三个水平上测量了眼睛的感知大小。结果显示，较低的眉毛（即离眼睛较近）会使眼睛看起来更大，而较高的眉毛会使眼睛看起来更小，而眉毛曲率对眼睛的感知大小没有影响。实验3研究了眼睛与眉毛之间的距离在实验1中所呈现的眼睛倾斜错觉中的作用。眼睛倾斜错觉不受眼睛与眉毛之间距离的影响，这表明眼睛倾斜错觉和眼睛大小错觉可能涉及不同类型的同化。我们从面部感知和可能的实际应用方面对这些错觉进行了讨论。
