The Ponzo Execlusion: A Geometrical Analytical Illusion
The Ponzo Illusion is a geometrical optical illusion which suggests that the human mind judges an object's size based on its background. This illusion takes place when two lines that are equal in size are placed between converging lines and seen as being different lengths. A visual example of a Ponzo Illusion would be a railroad track with a sunset as the background. The perpendicular lines that run vertical outside of the horizontal ones give the illusion that the tracks may actually be going off into the sunset. The participant’s perception of the lines between the other objects is what creates the illusion. Various studies have found a possible correlation between this illusion and other factors. The factor we will be exploring is

Another factor that relates to age would be the constancy scale. A constancy scale is said to stimulate the illusion that one line is further than the other because it is being overestimated. This is correlated with age in the fact that those that have experienced more linear cues will recognize the similarities in the lines (Wagner, 1977). Another study found that children ages 5 to 6 underestimated the size of the lines while those 7 to 10 years old and older adults guessed the size of the lines with more accuracy. On the other hand, young adults tended to overestimate the line size significantly (Kavsek and Granrud, 2012). While these studies focused on the age of the participants other studies found that other factors played a role in the effects of the Ponzo …show more content…
