Role of Maternal Gesture Use in Speech Use by Children With Fragile X Syndrome

Abstract

Purpose The purpose of this study was to investigate how maternal gesture relates to speech production by children with fragile X syndrome (FXS). Method Participants were 27 young children with FXS (23 boys, 4 girls) and their mothers. Videotaped home observations were conducted between the ages of 25 and 37 months (toddler period), and again between the ages of 60 and 71 months (child period). The videos were later coded for types of maternal utterances and maternal gestures that preceded child speech productions. Children were also assessed with the Mullen Scales of Early Learning at both ages Results Maternal gesture use in the toddler period was positively related to expressive language scores at both age periods, and was related to receptive language scores in the child period. Maternal proximal pointing, in comparison to other gestures, evoked more speech responses from children during the mother-child interactions particularly when combined with wh-questions. Conclusion This study adds to the growing body of research on the importance of contextual variables, such as maternal gestures, in child language development. Parental gesture use may be an easily added ingredient to parent-focused early language intervention programs.

For a variety of child language outcomes, available evidence reveals strong associations exist between this form of parent-sensitive responsiveness for highly heterogeneous groups of children with delays (see reviews by Landry et al 2008;Warren & Brady 2007) as well as for aetiologic subgroups such as children with Fragile X syndrome (Wheeler et al 2007;Warren et al 2010;Brady et al 2014;Hahn et al 2014). Similarly, for children with Down syndrome, the extent of supported joint engagement by parents (e.g.…”

Language Development in Infants and Toddlers With Fragile X Syndrome: Change Over Time and the Role of Attention

“…Considering gestures, Flenthrope and Brady (2010) found that increased gesture use by the child unexpectedly predicted lower vocabulary ability two years later in young children with FXS, whereas Hahn et al (2014) found that maternal gestures were positively associated with better later language in children with FXS. A series of studies focused on the responsivity of mothers of young children with FXS and demonstrated that early developmental level, autism symptoms, and maternal responsivity predicted vocabulary ability through age nine (Brady, Warren, Fleming, Keller, & Sterling, 2014; Warren et al, 2010).…”

Language Development From Early Childhood to Adolescence in Youths With Fragile X Syndrome

“…Using growth curve modeling, we showed that early and sustained maternal responsivity predicted child language outcomes. Specifically, relatively high rates of maternal responsivity during motherchild interactions were predictive of many language variables, including rates of communication and receptive and expressive vocabulary scores on the Mullen Scales of Early Learning (Brady et al, 2014;Hahn et al, 2014;Mullen, 1995;Warren et al, 2010). Komesidou et al (2017) examined development of syntax over time, as measured by the Index of Productive Syntax (IPSyn; Scarborough, 1990).…”
