Logometro: The psychometric properties of a norm-referenced digital battery for language assessment of Greek-speaking 4-7 years old children.

In educational and clinical settings, few norm-referenced tests have been utilized until now usually focusing on a single or a few language subcomponents, along with very few language rating scales for parents and educators. The need for a comprehensive language assessment tool for preschool and early school years children which could form the basis for valid and reliable screening and diagnostic decisions, led to the development of a new norm-referenced digital tool called Logometro®. The aim of the present study is to describe Logometro® as well as its psychometric characteristics.

Examining the relationship between oral language skills and executive functions: Evidence from Greek-speaking 4-5-year-old children with and without Developmental Language Disorder.

Background: Children with Developmental Language Disorder (DLD) have been found to demonstrate low performance in Executive Functions (EFs). However, the evidence-based data is so far scarce, especially for 4-5-year-old children. Most of the existing research involves English-speaking populations, while very few studies have been carried out with non-English-speaking populations.

Children's vocabulary and friendships: A comparative study between children with and without Specific Learning Disorder and Attention Deficit Hyperactivity Disorder.

Language skills are important in the formation and maintenance of friendships. Children with specific learning disorder (SLD) or attention-deficit/hyperactivity disorder (ADHD) experience difficulties with their relationships and have language-related problems. This study aims to examine how expressive and receptive vocabulary may relate to friendships of children with and without SLD or ADHD.

Executive Function, Working Memory, and Verbal Fluency in Relation to Non-Verbal Intelligence in Greek-Speaking School-Age Children with Developmental Language Disorder.

Developmental Language Disorder (DLD) is often associated with impairments in working memory (WM), executive functions (EF), and verbal fluency. Moreover, increasing evidence shows poorer performance of children with DLD on non-verbal intelligence tests relative to their typically developing (TD) peers. Yet, the degree and generality of relevant difficulties remain unclear.

Oral Language and Story Retelling During Preschool and Primary School Years: Developmental Patterns and Interrelationships.

Oral language and narrative skills constitute very critical factors for children's academic performance and social competence. The aim of the present study was to investigate the developmental patterns of story retelling, as well as the relationship between oral language and story retelling in preschool and primary school children. Two hundred and thirty-seven Greek-speaking children (4-5, 5-6 and 6-7 years old) participated in the study.

The Dimensionality of Oral Language Ability: Evidence From Young Greek Children.

Purpose This study investigated component skills in oral language development utilizing and validating a new assessment battery in a large ( = 800) and representative sample of Greek students 4-7 years of age. Method All participants enrolled in public schools from four geographical regions (Attica, Thessaly, Macedonia, and Crete) that varied demographically (urban, semiurban, and rural). For the individualized language assessments, we utilized mobile devices (tablet PC) to ensure children's interest and joyful participation as well as reliable administration procedures across sites.

Preschool Phonological and Morphological Awareness As Longitudinal Predictors of Early Reading and Spelling Development in Greek.

Different language skills are considered fundamental for successful reading and spelling acquisition. Extensive evidence has highlighted the central role of phonological awareness in early literacy experiences. However, many orthographic systems also require the contribution of morphological awareness.
