Zusammenfassung
This longitudinal study investigated how large-scale spatial representation changed
between the age of 4 and 6
years old. Fifteen children were asked to describe their
route home from the nursery school once a year, for three
years. Their spatial “Frames of Reference” (FoR) and point of view as indices of a spatial representation were
inferred from their spontaneous gestures and speech produced during the route description.

Analysis of children’s utterances and gestures showed that the mean length of utterance, speech time, and use of
landmarks or right/left terms to describe a route, all
increased with age. When children were 4 year
s old, most of
them made gestures aligned with the actual route
to their homes, and their hands tended to be raised above the
shoulder. In contrast, as a 6-year-old, gestures were used to give directions that did not match the actual route
, as
if the children were creating a virtual space in front of themselves. They also tended to produce more gesture-
units and to use a smaller gesture space than when they were younger. These results indicate that the development
of FoR in preschool age
may change from an egocentric FoR to a fixed FoR. The fixed FoR is based on external
landmarks as a reference point. Moreover, some 5- and 6-year-olds depicted their
routes as a map on the floor,
which can be considered to represent survey mapping.
This study suggests that when children are 4 years old, they have a predominantly topological route representation
but that by the time they are 5 and 6 years old, they also
have a coordinated survey-type representation. This
implies that a coordinated representation is available earlier than Piaget argued. Factors underlying the
development of spatial representation such as verbal encoding skills and the commuting experience were also
discussed
