PSY-402 Topic 3 DQ 1 Choose a perceptual difference that demonstrates an irregularity or dysfunction in one of the projection pathways. Explain how it could affect everyday life Class, Achromatopsia is a fancy way of saying color blind. A color blind person usually inherits this gene which has produced an abnormality in the photoreceptor system (Gazzaniga, Ivry & Mangun, 2013). Dichromat refers to those who are color blind who can only see two pigments of color: red and green if they are missing the medium or long wave lengths or yellow and blue if they are missing the short wavelenths. Anomalous trichromats are those who have all three of the photo- pigments, however, one of the three pigments has sensitivity (Gazzaniga, Ivry & Mangun, 2013). This could affect everyday life in many ways. Colors are used in symbolic ways all around us. Driving when color blind would be very difficult when it you come to a stoplight and are unsure of whether to stop or go. When color coded item come in to play at work as well that would cause great frustration as well. The occupation of a person could play in to the overall difficulty of the person being color blind as occupations such as pilot or electricians greatly rely on colors to represent many aspects of the job.
