This faculty was studied in an experiment in which a Charlie Chaplin mask was rotated; that experiment into this faculty was conducted by Richard Gregory. At William Wundt’s lab, George Stratton pioneered experiments using devices studying this faculty, one of which he combined with a harness. David Marr created a three-stage computational model for measuring this faculty’s processing. (10[1])LogMAR and a chart named for Herman Snellen measure this faculty. (10[1])An experiment named for this faculty, in which infants are placed on a (10[1])platform while their parent calls for them behind transparent (-5[1])plexiglass, was developed by Eleanor Gibson. This faculty, which names a “cliff,” (10[1])is used to perceive the phi phenomenon and other illusions. For 10 points, the occipital (-5[1])lobe processes what faculty that perceives color? ■END■ (10[2])
