Insights
Children born very prematurely show a weaker representational momentum (RM) effect, impacting motion perception. This effect also develops with age in both preterm and term-born children.
Area of Science:
- Cognitive Psychology
- Developmental Neuroscience
- Perceptual Psychology
Background:
- Representational momentum (RM) describes how memory for moving objects includes motion information, potentially causing location judgment errors.
- Children born very prematurely often experience challenges with motion perception and motor skills.
- Understanding RM in this population may illuminate developmental trajectories and underlying mechanisms.
Purpose of the Study:
- To investigate the representational momentum (RM) effect in children born very prematurely compared to those born at term.
- To examine age-related changes in the RM effect within these groups.
- To explore the implications of RM differences for motor planning and execution in preterm populations.
Main Methods:
- Comparison of the RM effect between very preterm and term-born children.
- Assessment of the RM effect across different age groups (5-6 years and 7-9 years).
- Utilizing tasks designed to measure errors in judging the location of moving objects.
Main Results:
- Children born very prematurely exhibited a weaker or absent RM effect compared to term-born children.
- A reduced RM effect was observed in younger children (5-6 years) relative to older children (7-9 years) in both groups.
- These findings indicate that the ability to represent motion in memory develops throughout this age range.
Conclusions:
- The development of representational momentum (RM) continues into middle childhood.
- Impaired RM in preterm children may contribute to observed difficulties in fine and gross motor planning.
- Deficits in predictive modeling or motion extrapolation could have broader developmental consequences.
Abstract:
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, 5-6year olds showed a reduced RM effect compared to 7-9year 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.

Impulse-Momentum Theorem
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its net...
