Insights
Toddlers show a developmental shift in spatial orientation, learning to use allocentric reference frames. Lifestyle factors like screen time and maternal weight gain negatively impact spatial cognition development.
Area of Science:
- Developmental psychology
- Cognitive neuroscience
- Child health
Background:
- Lifestyle factors (diet, physical activity, sleep) are linked to child health.
- The impact of lifestyle on cognitive abilities, especially spatial cognition, is understudied.
- Spatial cognition development includes a shift to allocentric reference frames around 2.5-3 years.
Purpose of the Study:
- To investigate the developmental shift in spatial orientation in toddlers.
- To explore the association between lifestyle factors and individual differences in spatial task performance.
Main Methods:
- Virtual reality study with 57 toddlers aged 30-36 months.
- Assessed spatial orientation using egocentric and allocentric reference frames.
- Correlated lifestyle factors (diet, screen time, etc.) with spatial task performance.
Main Results:
- A marginally significant developmental shift towards allocentric spatial orientation was observed.
- Increased screen time was negatively associated with spatial task performance.
- Higher maternal gestational weight gain was also linked to poorer spatial task performance.
Conclusions:
- Toddlers exhibit a developmental transition in spatial orientation strategies.
- Early life lifestyle factors, including screen time and maternal weight gain, may influence spatial cognitive development.
- Findings highlight potential targets for future research and intervention to support cognitive development.
Abstract:
Various lifestyle factors, including diet, physical activity, and sleep, have been studied in the context of children's health. However, how these lifestyle factors contribute to the development of cognitive abilities, including spatial cognition, remains vastly understudied. One landmark in spatial cognitive development occurs between 2.5 and 3 years of age. For spatial orientation at that age, children learn to use allocentric reference frames (using spatial relations between objects as the primary reference frame) in addition to, the already acquired, egocentric reference frames (using one's own body as the primary reference frame). In the current virtual reality study in a sample of 30-36-month-old toddlers (N = 57), we first demonstrated a marginally significant developmental shift in spatial orientation. Specifically, task performance with allocentric performance increased relative to egocentric performance (η2 = 0.06). Next, we explored a variety of lifestyle factors, including diet, in relation to task performance, to explain individual differences. Screen time and gestational weight gain of the mother were negatively associated with spatial task performance. The findings presented here can be used to guide future confirmatory studies about the role of lifestyle factors in the development of spatial cognition.
