LANDRY, MAUREEN O'REILLY, and LYONS-RUTH, KARLEN. Recursive Structure in Cognitive Perspective Taking. CmILD DEVELOPMENT, 1980, 51, 386-394. The construct validity of cognitive perspective-taking ability has been seriously questioned in recent literature. However, previous studies have tested a unidimensional model of perspective-taking skill rather than a model having 2 or more levels of perspective-taking ability beyond egocentrism. Drawing on multileveled models described in the literature, the present study (a) proposed a definition of a second level of recursive structure involved in perspective-taking tasks, (b) operationalized the distinction between level 1 and level 2 recursive perspective-taking in a task modeled after that of Urberg and Docherty, and (c) assessed the covariation of scores on this task with scores on 2 other tasks based on multileveled models. Children's scores on the new task correlated highly with scores on Miller, Kessel, and Flavell's cartoon task. Children's modal responses to Selman's interview task were hierarchically related to success on the other tasks, while children's best responses to the interview were strongly correlated with story and cartoon performance. Thus, analysis of levels of recursive structure in perspective-taking performance appears to isolate an important source of variance in children's responses to cognitive perspective-taking tasks.
