Abstract: The purposes of this study were to determine (1) whether three-year- old identical twin girls dressed alike and photographed in identical positions could be differentiated by the children and teachers in the Nursery School at the University of North Carolina at Greensboro (UNC-G) School of Home Economics, and (2) whether there were specific physical characteristics which children and teachers used to differentiate between the twin girls in identical photographs. The subjects for the study were 16 three- and four-year-old boys and girls, four teachers, and 11 student teachers involved in the Nursery School in the UNC-G School of Home Economics. Threeyear- old identical twin girls were photographed wearing identical clothing and in 10 identical positions. These photographs, presented as colored slides, were paired and presented to each of the subjects in four paired trials. The subjects were asked to identify one of the twins and their responses were recorded as being correct or incorrect. Data were analyzed by means of a three-factor ANOVA, a two-factor ANOVA, a t test for difference between independent means, and the Scheffé test for least significance difference.
