PSYB51H3 Lecture Notes - Motion Aftereffect, Color Blindness, Ishihara Test
Document Summary
Describe one experiment that would suggest that faces aren"t special. Fusiform area, experiment using gribo (neo-object) hence no practice effect. #2: detect colors through retina using 3 different tones. Trichromacy: mechanism which 3 detectors for many colours. Images are similar to sandwiches, one layer of blue, green and red. Cones are functions similarly to filters, specialized for 3 different types of wavelengths. Filters alone cannot tell what colour you are look at, cannot tell what is green or not. Univariance: only rate of action potential is telling information of stimulus. One kind of filters(photoreceptor) do not help much, cannot tell discrimination. Each cones response to different certain wavelength, result as a curve of graph. E. g. some cone responses greatest to green, and yellow the second. 2 colour (blue and orange) result same # of output, S cones: short cones m-cones: middle cones l-cones: long cones. Scotopic: refer to dark light, using rod cells, no able to discriminate colours.
