PSYC 4150 Study Guide - Quiz Guide: Mach Bands, Presbyopia, Retinitis Pigmentosa
Document Summary
The perceptual process is made up of many stages. Include a discussion of bottom-up and top-down processing. Describe the 3 classic methods of determining threshold and give an example of how each might be used (to determine either absolute or difference threshold). What is the (cid:272)o(cid:374)(cid:272)ept (cid:271)ehi(cid:374)d/(cid:449)hat fa(cid:272)tors deter(cid:373)i(cid:374)e d", b, n, Make sure to explain how d" and b can vary. Discuss what a roc curve is (component parts, what do they mean). Co(cid:373)pare the per(cid:272)eptio(cid:374) (magnitude estimation) of brightness, line length and electric shock with their actual physical intensities. Describe them in terms of their physical characteristics and corresponding perception. Draw a light wave and label all of the parts in terms of physical characteristics. Explain the possible firing patterns of an on-center/off surround receptive field. Using mach bands the hermann grid illusion, or pyramid illusion explain how lateral inhibition works.
