Which step of the sensory pathway is represented by perceptual filling-in of the physiological blind spot?
A. interpretation B. stimulus C. transduction into receptor potential D. action potential transmission Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about retinal signaling? What other information is related to the question? Choose Answer Given what you now know, what information is most likely to produce the correct answer? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
