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.

Comparative analysis of initial vocalizations of preterm and full-term infants with and without risk for development.

Purpose: To compare the evolution of vocalization in preterm and full-term infants, with and without risk for development, analyzing the possible association of sociodemographic, obstetric and psychosocial variables with vocalization.

Methods: The study sample consisted of 30 infants, aged 3 months and 1 day to 4 months and 29 days (Phase 1) and 6 months and 1 day to 7 months and 29 days (Phase 2), of both genders, with gestational age <37 weeks (preterm group) and >37 weeks (full-term group). The following instruments were used for data collection: Child Development Risk Indicators (IRDl), the Denver II Test, an interview on the experience of motherhood with sociodemographic, obstetric and psychosocial data, as well as filming of the mother-infant dyad at the two phases of the research.

Effects of prematurity on language acquisition and auditory maturation: a systematic review.

Purpose: To verify which damages prematurity causes to hearing and language.

Research Strategies: We used the decriptors language/linguagem, hearing/audição, prematurity/prematuridade in databases LILACS, MEDLINE, Cochrane Library and Scielo.

Selection Criteria: randomized controlled trials, non-randomized intervention studies and descriptive studies (cross-sectional, cohort, case-control projects).

Enunciative categories in the description of language functioning of mothers and infants aged 1-4 months.

Objective: To present categories which explain the language functioning between infants and their mothers from Benveniste's concept of semiotic system, and verify whether such categories can be described numerically.

Method: Four mother-infant dyads were monitored in three stages. The first study consisted of a qualitative analysis of the transcribed video recordings conducted in each stage.
