Brief Summary
The present project aims at identifying very early electrophysiological risk markers for language impairments. The long-term goals of the study include the characterization of learning developmental trajectories in children at high risk for language impairments. In this project, all the infants of the Medea BabyLab cohort are followed-up until school age. Since these infants have complete information on early electrophysiological markers, the final goal of the project is the characterization of their learning developmental trajectories and the construction of a multi-factor prognostic model that includes the neurophysiological processes underlying basic-level skills as potential biomarkers for predicting later reading and spelling skills.

Outcome Measures
Primary Outcomes (11)
Expressive vocabulary at age 3 years
Standardized score in the Language Development Survey (Rescorla, 1989; Rescorla et al., 2014). Minimum=5; Maximum=95 (higher scores mean a better outcome).
Age 3 years
Phonological awareness at age 3 years
Raw score in a syllabic blending task (created ad hoc). Scores are percentages of accuracy (higher scores mean a better outcome).
Age 3 years
Syntactic comprehension at age 3 years
Standardized scores in the syntactic comprehension subtests, taken from 'Test for language evaluation', Cianchetti e Fancello, 1997. Z-scores are calculated (higher scores mean a better outcome).
Age 3 years
Lexical comprehension at age 3 years
Raw score in the lexical comprehension subtest, taken from 'Battery for language evaluation in children 4-12 years', Marini et al., 2015. Scores are percentages of accuracy (higher scores mean a better outcome).
Age 3 years
Short-term verbal memory at age 4.5 years
Standardized scores in the pseudo-word repetition subtest, taken from 'Battery for language evaluation in children 4-12 years', Marini et al., 2015. Z-scores are calculated (higher scores mean a better outcome).
Age 4.5 years
Phonological awareness at age 4.5 years
Standardized scores in the phonological awareness subtests taken from 'Evaluation of phonological awareness skills', Marotta et al., 2008. Mean=10, Standard Deviation=3 (higher scores mean a better outcome).
Age 4.5 years
Phonological awareness at age 6 years
Composite score of the standardized scores in the phonological awareness subtests (phoneme identification, phonemic segmentation), Cornoldi et al., 2009. Z-scores are calculated (higher scores mean a better outcome).
Age 6 years
Letter identification, knowledge, and writing at age 6 years
Raw scores in the letter identification, knowledge, and writing subtests, taken from "Preschool Screening", Savelli et al., 2013. Minimum=0, Maximum=20 (higher scores mean a better outcome).
Age 6 years
Reading (accuracy, speed and comprehension) at age 8 years
Standardized scores in the reading subtest, taken from 'Reading and comprehension assessment', Bonifacci et al., 2014. Z-scores are calculated (higher scores mean a better outcome).
Age 8 years
Spelling at age 8 years
Standardized scores in the spelling task (Marinelli et al., 2016). Z-scores are calculated (higher scores mean a better outcome).
Age 8 years
Phonemic awareness at age 8 years
Raw scores in the spoonerisms subtest taken from 'Evaluation of phonological awareness skills', Marotta et al., 2008. Minimum=0, Maximum=30 (higher scores mean a better outcome).
