Representational Momentum in Children Born Preterm and at Term
Taylor, Nicole M.; Jakobson, Lorna S.
Brain and Cognition, v72 n3 p464-471 Apr 2010
The term "representational momentum" (RM) refers to the idea that our memory representations for moving objects incorporate information about movement--a fact that can lead us to make errors when judging an object's location (the RM effect). In this study, we explored the RM effect in a sample of children born very prematurely and a sample born at term. Because preterm children are known to be at risk for problems with motion perception, we anticipated that they would show a weaker or absent RM effect. This prediction was confirmed. In addition, we found that, in both samples of children, 5-6 year olds showed a reduced RM effect compared to 7-9 year olds. These results demonstrate that the ability to represent motion information in memory shows continued development over this age range, and may help to elucidate factors contributing to problems with fine and gross motor planning and execution that have been observed in the preterm population. We propose that problems affecting the formation, maintenance, or use of predictive models, or motion extrapolation skills, may have cascading effects on the development of other abilities.
