“…Other studies have trained parents of children with Down syndrome in shared book reading techniques (van Bysterveldt et al., 2006) or used shared book reading as one of a number of approaches to support children's development of vocabulary, letter knowledge, print concepts, phonological awareness and speech articulation (Bonagamba & Schmidt, 2019; van Bysterveldt et al., 2010b). Based on a small sample and a low dose of three sessions, Bonagamba and Schmidt (2019) reported that their shared book reading procedure was not effective for teaching nouns to young children with Down syndrome. In contrast, findings suggest that targeting parent–child interactions in shared book reading is an effective intervention approach to promote phonological awareness and letter knowledge (van Bysterveldt et al., 2006) and, when integrated with other approaches, to remediate speech error patterns (van Bysterveldt et al., 2010b).…”
