“…This makes these responses powerful moments for word learning, and any reduction in the infant’s opportunities to access these moments has cascading implications for language learning. Thus, for example, both EL-LD and EL-ASD infants show slower growth in expressive vocabularies across the first 2 years than do TL infants (Iverson et al, 2018), and EL-ASD infants, compared with TL and other EL infants, show different relations between actions and gestures, on the one hand, and word comprehension, on the other (Roemer et al, 2019). Thus, although early differences in the development of sitting and object exploration may seem, at first glance, to be far afield from language development, the pathway just described suggests that these differences may significantly influence the emergence of early communicative behaviors and caregiver input in ways that may not benefit language learning.…”

The first year of life is punctuated by explosions of growth in motor and language abilities. This is not a coincidence. The notion of developmental cascades provides a conceptual framework for considering ways in which advances in one component of a developing system can exert far-reaching and lasting change in other domains. In this article, I review evidence for the cascading effects of early motor advances on the developing communication and language system and describe how differences in the timing of these advances may have consequences for these effects.

“…In early communicative development, it is noted that language and gesture are closely linked (Rowe et al, 2008) and gesture production precedes and may have a subsequent role in language acquisition, supporting that there are specific and complex mechanisms underlying language development (Roemer et al, 2019). While the link between gesture and language production has been extensively studied in TD infants (Rowe et al, 2008), it remains understudied in ASD toddlers and in HR-ASD infants.…”

Early developmental trajectories of expressive vocabulary and gesture production in a longitudinal cohort of Italian infants at high‐risk for Autism Spectrum Disorder

Delays in language are a hallmark feature of Autism Spectrum Disorder (ASD). However, little is known about the predictive role of language developmental trajectories on ASD. The present study aimed at identifying early different language developmental profiles of infants at high familial risk for ASD (HR-ASD) and testing their predictive role on ASD symptoms at 2 years. The role of gestures on socio-communicative skills has also been explored. Trajectories of expressive vocabulary were investigated in 137 HR-ASD infants at 12, 18, and, 24 months of age. Parents were requested to complete the Italian version of the MacArthur-Bates Communicative Development Inventory and ASD symptoms were measured by ADOS-2. Latent class growth analysis defined four trajectories: above average language development group (above-average LD, 18.2%), normal language development group (NLD, 38.7%), late-onset language development group (late-onset LD, 11.7%), and a group of children with stable language delay (SLD, 31.4%). Results showed that the SLD group obtained higher communicative difficulties and restricted/repetitive behavior compared to the other groups. Examining early increase of produced gestures in the different language classes, we found fewer produced gestures between 12 and 18 months in the SLD group compared to the late-onset LD group. The results identified clusters of HR infants who follow similar estimated trajectories based on individual differences in language development. These patterns of early language acquisition, together with produced gestures, may be predictive of later ASD symptoms and useful for planning prompt intervention.Lay Summary: Language/gesture deficits are hallmark features of Autism Spectrum Disorder (ASD), but the predictive role of communicative trajectories on ASD remains unclear. In a longitudinal Italian sample of infants at high familial risk for ASD (HR-ASD), we tested if language trajectories and their link with gestures can predict ASD symptoms. We found four trajectories and HR infants with a stable language delay (SLD) trajectory showed more ASD symptoms later on. SLD infants produced fewer gestures compared to late-onset language development group that show more typical communicative skills.

Within this manual you will find a descriptive guide to the MHINT coding procedure, general rules for coding, and detailed descriptions of each ‘behaviour group’ with illustrative examples.This manual aims to capture as many relevant behaviours for the evaluation of an interaction as possible, with the underlying hypothesis that individual differences in behaviours can occur subtly and that micro-behaviours are of great importance because they provide specific targets for intervention.The coding scheme can be applied to footage obtained from video cameras installed in the home, those used by an observer, or as in our own research, through wearable headcams and a ‘spy’ photo-frame video camera (Lee et al., 2017). Combined, these methods give the observer the opportunity to code behaviours from different perspectives and, interestingly, to obtain the perspective of the participants. The advantages of this approach are explained in Lee et al. (2017).For ease of use, this manual has been divided into five different sections: perspectives, independent variables, subjects, behaviours, and modifiers. To begin, each of these terms is defined.
