  • Sustained looking at faces at 5 months of age is associated with socio‐communicative skills in the second year of life

    Open Access•Charlotte Viktorsson, Ana Maria Portugal et al.•ARTICLE•Infancy•2024

    Efficiently processing information from faces in infancy is foundational for nonverbal communication. We studied individual differences in 5‐month‐old infants' ( N = 517) sustained attention to faces and preference for emotional faces. We assessed the contribution of genetic and environmental influences to individual differences in these gaze behaviors, and the association between these traits and other concurrent and later phenotypes. We found a…

  • Preferential looking to eyes versus mouth in early infancy

    Open Access•Charlotte Viktorsson, Ana Maria Portugal et al.•ARTICLE•Journal of Child Psychology and…•2023

    BACKGROUND: From birth, infants orient preferentially to faces, and when looking at the face, they attend primarily to eyes and mouth. These areas convey different types of information, and earlier research suggests that genetic factors influence the preference for one or the other in young children. METHODS: In a sample of 535 5-month-old infant twins, we assessed eye (relative to mouth) preference in early infancy, i.e., before neural systems f…

  • Infants’ looking preferences for social versus non-social objects reflect genetic variation

    Open Access•Ana Maria Portugal, Charlotte Viktorsson et al.•ARTICLE•Nature Human Behaviour•2023•Cited by: 1•References: 54

    To what extent do individual differences in infants’ early preference for faces versus non-facial objects reflect genetic and environmental factors? Here in a sample of 536 5-month-old same-sex twins, we assessed attention to faces using eye tracking in two ways: initial orienting to faces at the start of the trial (thought to reflect subcortical processing) and sustained face preference throughout the trial (thought to reflect emerging attention…

  • Pupil size and pupillary light reflex in early infancy

    Open Access•Ana Maria Portugal, Mark J Taylor et al.•ARTICLE•Journal of Child Psychology and…•2022

    BACKGROUND: Measures based on pupillometry, such as the pupillary light reflex (PLR) and baseline pupil size, reflect physiological responses linked to specific neural circuits that have been implicated as atypical in some psychiatric and neurodevelopmental conditions. METHODS: We investigated the contribution of genetic and environmental factors to the baseline pupil size and the PLR in 510 infant twins assessed at 5 months of age (281 monozygot…
