The Relationship between the Perception of Axes of Symmetry and Spatial Memory during Early Childhood
Ortmann, Margaret R.; Schutte, Anne R.
Journal of Experimental Child Psychology, v107 n3 p368-376 Nov 2010
Early in development, there is a transition in spatial working memory (SWM). When remembering a location in a homogeneous space (e.g., in a sandbox), young children are biased toward the midline symmetry axis of the space. Over development, a transition occurs that leads to older children being biased away from midline. The dynamic field theory (DFT) explains this transition in biases as being caused by a change in the precision of neural interaction in SWM and improvements in the perception of midline. According to the DFT, young children perceive midline, but there is a quantitative improvement in the perception of midline over development. In the experiment reported here, children and adults needed to determine on which half of a large monitor a target was located. In support of the DFT, even the youngest children performed above chance at most locations, but performance also improved gradually with age. (Contains 3 figures and 1 note.)
