title: Effects of hierarchical organization on children's judgments of distance and direction.
abstract: The impact of the hierarchical organization of a space on judgments of direction and distance was assessed in two studies using two-dimensional models analogous to those used by A. Stevens and P. Coupe (1978, Cognitive Psychology, 10, 422-437). In each study the models contained two stars and were divided into two parts by a curved boundary line. In the Homogeneous condition the stars were located in the same subsection. In the Congruent condition the leftmost star was in the left subsection and the rightmost star was in the right subsection. In the Incongruent condition the rightmost star was in the left subsection and the leftmost star was in the right subsection. In Experiment 1 first graders, third graders, and college students were required to remember the location of the stars. Results indicated that the first and third graders tended to use the relationship between the subsections as a clue to the relationship between the sites within them, thus extending the results of Stevens and Coupe (1978) to children. In Experiment 2 preschoolers, first, and third graders were asked to judge with the materials directly in front of them, which of the two stars was closer to a site located in one of the subsections. Results indicated that the Incongruent condition led to errors among the preschoolers and first graders but not the third graders, thus indicating that these groups tended to judge as closer the site within the same subsection even though it was really farther away. The results of both studies are discussed as indicative of a tendency among young children to impose organization on information encoded in memory and in relation to increases in metric accuracy, decentration, and efficient scanning which enable them to more accurately evaluate when such organization is and is not appropriate. Implications for behavior in large-scale environments are also discussed, with particular reference to the effect of barriers on perceptions of distance and direction.
