Insights
Infant inhibition develops with motor skills. More complex tasks increase perseverative errors, especially in walkers compared to crawlers, impacting cognitive resources.
Area of Science:
- Developmental Psychology
- Cognitive Neuroscience
- Motor Development
Background:
- Inhibition is crucial for cognitive development.
- Locomotion provides a context for studying infant inhibition.
- Previous research suggests motor experience influences cognitive abilities.
Purpose of the Study:
- To investigate the development of inhibition in infants within a locomotor context.
- To examine the impact of task difficulty on perseverative errors.
- To explore the relationship between locomotor experience and inhibitory control.
Main Methods:
- Within-subjects design using A-not-B tasks with varying locomotor demands.
- Experiments involved walking and crawling 13-month-old infants.
- Analysis of perseverative errors in relation to task difficulty and locomotor experience.
Main Results:
- Perseverative errors were more frequent in high-demand conditions than low-demand conditions.
- Walking infants showed more perseveration than crawling infants.
- Infants with more locomotor experience exhibited less perseveration, suggesting improved inhibitory control.
Conclusions:
- Locomotor development is linked to enhanced inhibitory control in infants.
- Cognitive capacity and attentional resources play a role in infant perseveration.
- Motor expertise facilitates cognitive flexibility by freeing up attentional resources.
Abstract:
This research examined the development of inhibition in a locomotor context. In a within-subjects design, infants received high- and low-demand locomotor A-not-B tasks. In Experiment 1, walking 13-month-old infants followed an indirect path to a goal. In a control condition, infants took a direct route. In Experiment 2, crawling and walking 13-month-old infants crawled through a tunnel to reach a goal at the other end and received the same control condition as in Experiment 1. In both experiments, perseverative errors occurred more often in the high-demand condition than in the low-demand condition. Moreover, in Experiment 2, walkers perseverated more than crawlers, and extent of perseveration was related to infants' locomotor experience. In Experiment 3, the authors addressed a possible confound in Experiment 2 between locomotor expertise and locomotor posture. Novice crawlers perseverated in the difficult tunnels condition, behaving more like novice walkers than expert crawlers. As predicted by a cognitive capacity account of infant perseveration, overtaxed attentional resources resulted in a cognition-action trade-off. Experts who found the task less motorically effortful than novices had more cognitive resources available for problem solving.
