Preference for eyes at 5\u00a0months was associated with higher parent ratings of receptive vocabulary at 14\u2009months. No statistically significant association with later autistic traits was found. Preference for eyes was strikingly stable across different stimulus types (e.g., dynamic vs. still), suggesting that infants' preference at this age does not reflect sensitivity to low\u2010level visual cues.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These results suggest that individual differences in infants' preferential looking to eyes versus mouth to a substantial degree reflect genetic variation.
