Short-term memory (STM) challenges are often observed in children with Down syndrome (DS), but existing early STM measures introduce measurement confounds in this population. To address the need for valid early STM measures for future DS interventions, this study evaluated the psychometric properties of a modified Corsi Span task, administered to…

There is evidence that mastery motivation contributes to developmental outcomes, both for typically developing individuals and for those with disabilities such as Down syndrome. Mastery motivation appears to be a stable trait, at least during early childhood, but research with adults has been restricted by the absence of an appropriate measure.…

Executive function (EF) is frequently an area of vulnerability in conditions associated with intellectual disability, like Down syndrome (DS). However, current EF evaluation approaches are not designed for children with underlying neurodevelopmental conditions and may not demonstrate construct validity due to interpretational confounds. The…

Down syndrome is the most common genetic syndrome of intellectual disabilities with a distinct linguistic profile. Language research so far has come mainly from the English language, a language with different syntax and morphology from many other languages, including Greek, indicating a paucity of research findings in the Greek language. Given the…

Part C early intervention (EI) starts no earlier than birth, even with a prenatal diagnosis resulting in automatic eligibility. Despite other early U.S. home visiting programs beginning prenatally and the increasing likelihood of uncovering certain diagnoses prenatally, pregnant families cannot access EI. This study sought to understand families'…

Background: Parent-mediated intervention (PMI) is a potentially scalable approach for tailored interventions in neurogenetic conditions like Down syndrome (DS). Because PMIs require ongoing parent engagement, they must be developed in alignment with the needs of intended users. The present study examined caregiver opinions and preferences to…

Background: People with Down syndrome (DS) are predisposed to challenges with executive functions (EF), which are crucial for adaptive outcomes and academic success. Early interventions targeting EF are therefore critical. The present study analysed Italian data on the acceptability, enjoyability and household implementation of EXPO (EXecutive…

Background: Research investigating feeding problems in children with Down syndrome is scarce. This study investigated feeding problems, eating behaviours and parental feeding practices in children with Down syndrome (n = 40), and typically developing (TD) children of the same age and sex (n = 40). Method: Parents of children aged 6-months to…

The present study aimed to examine the effects of the Quality Book Reading (NIKO) Early Intervention Program on Turkish mothers of children with Down syndrome aged between 2 and 6 years and their children. The research was conducted using the convergent parallel mixed design with 17 mother-child dyads determined by random assignment. Nine…

Perceptions of parents of young children receiving early intervention are important to understand. Parents have valuable opinions on the delivery of early interventions services and can provide critical feedback that can help professionals revise their existing early intervention delivery modalities. In the current study, we examined the…

Background: To document whether the sociocognitive peculiarities of people with Down Syndrome impact the construction of attachment at different ages, a systematic review of the literature was carried out. Method: This review followed the Preferred Reporting Items for Systematic Reviews and MetaAnalyses, was conducted on three databases: psycINFO,…

Purpose: This study examined the effects of an intensive voice treatment Lee Silverman Voice Treatment (LSVT LOUD) on children with Down syndrome (DS) and motor speech disorders. Method: A Phase I, multiple baseline, single-subject design with replication across nine participants with DS was used. Single-word intelligibility, acoustic measures of…

Functional communication training (FCT) is an evidence-based intervention that while often effective, can result in rote responding, reduced generalizability of target behavior, and resurgence of challenging behavior (CB) during treatment lapses. Lag schedules of reinforcement have been successfully used to address these concerns. We applied an…

From the second year of life, children with typical development (TD) demonstrate the ability to form word-word relations. However, this ability has received little attention in children with Down syndrome (DS). We investigated their ability to establish associative relationships between words that tend to occur in the same context. Two groups of…

Young children with Down syndrome (DS) often demonstrate impaired oral vocabulary development; however, few intervention studies have focused on this population. One promising method to improve the oral vocabulary of young children with DS may be to train their parents to intervene at home. In this study, we used tele-education methods (e.g.,…
