What is categorical perception and how does it demonstrate perceptual organization?

please answer in full sentences, indicating the question and the letter you are answering.
Question1:
a) What is categorical perception and how does it demonstrate perceptual organization?
b) Explain the study I ran that was described in class (ba-mba study) and explain how it relates to categorical perception.
Question 2:
a). One of the themes in this course is the notion of patterns. In one or two sentences, explain how olfactory receptor neurons relate to the notion of patterns. Then, identify a similar process in the visual system.
b). One of the themes in this course is transduction. All senses require transduction of some form of energy/input into electrical signals. Each sense has their own type of receptor(s) that accomplish(es) transduction. What are the hearing receptors called? What are the olfactory receptors called? List two differences between them (other than where they are found).
c). One of the themes in this course is maps. Most senses contain a map somewhere along their sensory pathways. What is the map in the olfactory sense called? What is the map in the auditory sense called? How is the map in the olfactory sense different from the ones found in the other senses (including hearing)? Name one other way that the olfactory sense differs from all the other senses.
