Relationship between enunciative signs of language acquisition and language assessment through the Bayley III scale at 24 months.

Purpose: To analyze the correlation between the results obtained on the SEAL and the Bayley III Scale and compare babies with and without delay in language acquisition at 24 months concerning the performance obtained by them and their mothers on the SEAL from 3 to 24 months.

Methods: The SEAL collection consists of 15-minute footages of 45 babies aged from 3 to 24 months old in interaction with their mothers, who were assessed by two trained speech therapists for the use of the SEAL. At 24 months, the 45 babies were assessed using the Bayley III Scale and the item language was selected to classify them with and without delay.

Cortical Auditory Evoked Potentials in 2-Year-Old Subjects.

 Cortical auditory evoked potentials (CAEPs) can be used to evaluate both peripheral and cortical components of auditory function, and contribute to the assessment of functional sensitivity and auditory thresholds, especially in neonates and infants. Auditory evoked potentials reflect auditory maturity and precede the acquisition of more complex auditory and cognitive skills, and are therefore crucial for speech and language development.  The aim of the present study was to determine the presence, latency and amplitude of CAEP components in response to verbal stimuli in children aged 2 years old.

Risk indicators for hearing loss and language acquisition and their relationship with socioeconomic, demographic and obstetric variables in preterm and term babies.

Purpose: To compare the frequency of risk indicators in preterm and full-term babies; to analyze the possible relationships among the presence of risk for hearing loss with language acquisition and socioeconomic, demographic and obstetric variables.

Methods: This is a longitudinal cohort study, with a sample of 87 babies. Gestational, obstetric and sociodemographic data were collected from mothers and babies.
