Background and Aims: The purpose of this exploratory study was to expand existing literature on prelinguistic vocalizations by reporting results of the first home-based longitudinal study examining a wide variety of behaviors and characteristics, including early vocalizations, across infants at low and elevated risk of autism spectrum disorder…

The first year of life is an essential phase for all psychological areas in child development. The key competences, vital for all development processes of the child, focus on the communication and the socio-emotional competencies, mostly because the infant is strongly dependent of the adult care environment. The quality of the primary caregiving…

Faces convey important information about the social environment, and even very young infants are preferentially attentive to face-like over non-face stimuli. Eye-tracking studies have allowed researchers to examine which features of faces infants find most salient across development, and the present study examined scanning of familiar (i.e.,…

Case study research methodology was used to describe the play behaviors of three infants at 12 months of age, who were later diagnosed with an autism spectrum disorder. Data included standardized test scores, and analyses of video footage of semi-structured play sessions from infants identified as high risk for autism, because of having a sibling…

There are no known biomedical or genetic markers to identify which infants with galactosaemia (GAL) are most at risk of poor language skill development, yet pre-linguistic communicative "red flag" behaviours are recognised as early identifiers of heightened vulnerability to impaired language development. We report on pre-linguistic…
