In module nineteen of chapter four, students learn about the different perceptions, adaptations and cues that the eyes make such as depth perception, perceptual constancy, and monocular cues. Something I found very interesting while reading this chapter, was the many different monocular cues that the eyes themselves must put together in order to create a full picture for us. These cues are: relative height, relative size, interposition, linear perspective, light and shadow, and relative motion.
