ABSTRACT
BACKGROUND: Down syndrome is the most common genetic cause of intellectual disability, affecting 700-800 babies annually in the UK (Wu J, Morris J, Eur J Hum Genet 21:1016-9, 2013). Children with Down syndrome have difficulties developing language skills. These difficulties can have long-term negative consequences for all aspects of their lives including social development, education and employment opportunities, and emotional wellbeing and mental health (Irwin LG et. al 2007). These aspects all have the potential to be improved through targeted early language intervention. Parents and Children Together (PACT) is a parent-delivered early language teaching programme for typically developing pre-school children at risk of language delays. A previous project (Burgoyne K, J Child Psychol Psychiatry 59(5):545-55, 2018) showed that PACT leads to improvements in children's language and early literacy skills. Our team has worked closely with six families to adapt PACT for children with Down syndrome. The aim of the current study is to conduct a feasibility randomised controlled trial (RCT) to evaluate the feasibility of a definitive RCT and explore initial evidence of the adapted programme's potential to support children's language and literacy development. METHOD: This is a two-arm feasibility randomised controlled trial in which children will be randomly allocated to either a PACT-DS group or to a waiting control group (who will receive intervention at the end of the project). We aim to recruit 28-30 children with Down syndrome (aged 3-6 years) and their parents/caregivers to take part. The PACT-DS group will be trained to deliver PACT-DS every day (20 min a day; 5 days a week) to their child over 30 weeks. We will collect data using assessments of child language and early literacy, measures of parent wellbeing, qualitative surveys and interviews, and monitoring data to explore trial feasibility (including recruitment and retention of families and adherence and acceptability of intervention) and cost and benefits. Data will be collected before intervention, immediately after the 30-week intervention programme, and 6 months after intervention ends. Clear progression criteria will be used to assess suitability for a definitive trial. DISCUSSION: This study represents initial steps in developing a definitive trial of the PACT-DS programme and will add to the limited evidence base on early language intervention for children with Down syndrome. This programme of research has the potential to make significant advancements in early language intervention research and practice for this group. TRIAL REGISTRATION: The trial is registered with the ISRCTN registry: study ID ISRCTN63251282 . Registered on 14 July 2023.
ABSTRACT
When collaboratively solving problems, children discuss information reliability, for example, whether claims are based on direct or indirect observation, termed as "metatalk". Unlike English in which evidential marking is optional, languages with obligatory evidential marking such as Turkish, might provide children some advantages in communicating the reliability of their claims. The current preregistered online study investigated Turkish- and English-speaking 3- and 5-year-old children's (N = 144) use of metatalk. The child and the experimenter (E) were asked to decide in which of the two houses a toy was hiding. One house had the toy's footprints. When E left the Zoom meeting, an informant told the child that the toy was in the other house without the footprints in three within-subjects conditions. In the direct-observation condition, the child witnessed the informant move the toy. In the indirect-witness condition, the informant checked both houses and said that the toy was in the other house. In the indirect-hearsay condition, the informant simply said that the toy was in the other house. When E returned, the child had to convince E about how they knew the toy was in the other house using metatalk (e.g., "I saw it move"). Turkish-speaking children used metatalk more often than did English-speaking children, especially in the direct-observation condition. In the two indirect conditions, both groups of 5-year-olds were similar in their use of metatalk, but Turkish speaking 3-year-olds produced metatalk more often than did English-speaking 3-year-olds. Thus, languages with obligatory evidential marking might facilitate children's collaborative reasoning. RESEARCH HIGHLIGHTS: Children as young as 3 years of age can produce metatalk. Turkish-speaking children produce metatalk more often than English-speaking children. The difference between the two linguistic groups is more pronounced at age 3.
ABSTRACT
In collaborative decision-making, partners compare reasons behind conflicting proposals through meta-talk. We investigated UK-based preschoolers' (mixed socioeconomic status) use of meta-talk (Data collection: 2018-2020). In Study 1, 5- and 7-year-old peer dyads (N = 128, 61 girls) heard conflicting claims about an animal from two informants. One prefaced her claim with "I know"; the other with "I think". Dyads identified the more reliable informant through meta-talk ("She said she knows"). In Study 2, 3- and 5-year-olds (N = 64, 34 girls) searched for a toy with an adult partner making incorrect proposals. Children refuted this through reporting what they had witnessed (It cannot be there because "I saw it move", "she moved it"). In preschool period, children start using meta-talk to make rational collaborative decisions.
