- Why it is important to establish the relative role of genetic and environmental influences on eye preference relative to mouth preference in early infancy.
- What are the implications of what infants look at being largely based on their individual genotype, before they can select their environment by means of crawling or walking.
- Preference for eyes at 5 months was positively correlated with parent’s assessment of vocabulary at 14 months.
- No significant association was found between mouth or eye preference and later socio-communication difficulties, nor later autistic traits.
- How might these findings inform future practice or influence the way we think about infant development.
- How does an infant paying more attention to the eyes, compared to those that pay more attention to the mouth, appear to translate into later communication skills and learning?
