Psychology 1000 Lecture 4 Perception II Depth Perception Size Constancy Perceptual Problem Solving Next Time: Sleep Scan: p.191 - 203 Questions Covered: How do we perceive depth? What happens after we determine object distance? How do we figure out what we're looking at? Retinal ganglion cell --> prefer spots of light Non-retinal cell --> line or space specific Gestalt Approach --> importance of expectation and context --> binocular cues Can only be used when using 2 eyes --> only on organisms that have eyes 65mm or less away from each other --> works based on retinal disparity --> distance between 2 targets on each retina Is not the same! --> monocular cues i.e. using the TV Relative size --> all things equal --> object that are farther away are perceived to be farther away Overlap --> 2 targets, when one contour overlaps the other --> the one in the foreground blocks out background Linear perspective --> parallel lines converge in the distance Texture gradient

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
