a visual-perceptual task in which the participant is required to synthesize elements from fragmented, ambiguous pictures of items to form a “whole.” Poor performance on this test (i.e., inability to report complete objects) may indicate impairment of right-hemisphere brain function. This testing technique was initially developed in 1931 by U.S. psychologist Roy F. Street but has since been adapted by others. The original Street Gestalt Completion Test (also known as the Street Gestalt test or Street test) consists of 13 incomplete silhouettes of common objects.
