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 (10[1])processing. (-5[1])LogMAR and a chart named for Herman Snellen (10[1])measure this faculty. (10[1])An experiment named for this faculty, in which infants are placed on a platform while their parent calls for (10[1])them behind transparent plexiglass, was developed by Eleanor Gibson.
