2A: How is this illusion related to depth perception?
When we see the two lines to be at different distance, our brain try to figure out that which is near to our vision by showing the visible distance. So the line which form near edge of an exterior corner, we think that this line looks shorter than its real length and the line which form far edge of an interior corner, we think that this looks longer that its real length. So by this way it’s related to our depth perception.
3A: What were your results on the second Müller-Lyer Illusion test? …show more content…
So I was more alert to figure out that two halves of the horizontal line are equal or not. Furthermore, in second trial when I clicked the finish button it indicate me the correct line for two halves of horizontal line. Therefore, I try to adjust my line to match the correct line.
2: The Horizontal-Vertical Illusion
2A: What were your results on the Horizontal-Vertical Illusion test? My average adjusted length was quite close to the correct length, so it concluded that my perception of vertical line does not influenced by illusion.
2B: What are the two factors related to this illusion?
a) Object that is close to the top of our visual field; most likely come into view to be more distant. Our brain corrects the apparent size of an object to adjust for differences in depth. Therefore, lines that are more distant are visible lengthened. That why the vertical line of the upper half will appear longer than equally long horizontal line.
b) The vertical line bisects the horizontal line. So when we try to figure out the line length, we tend to focus only half of the horizontal line, therefore we underestimate the length of the horizontal
