Vocabulary of preschool children with typical language development and socioeducational variables

ABSTRACT

Purpose

To investigate the correlation between age, socioeconomic status (SES), and performance on emissive and receptive vocabulary tests in children with typical language development.

Methods

The study sample was composed of 60 preschool children of both genders, aged 3 years to 5 years 11 months, with typical language development divided into three groups: G I (mean age=3 years 6 months), G II (mean age=4 years 4 months) and G III (mean age=5 years 9 months). The ABFW Child Language Test - Vocabulary and the Peabody Picture Vocabulary Test (PPVT) for emissive and receptive language were applied to the preschoolers. The socioeconomic classification questionnaire of the Brazilian Association of Survey Companies (ABEP) was applied to the preschoolers’ parents/legal guardians. Data were analyzed according to the criteria of the aforementioned instruments and were arranged in Excel spreadsheet for Windows XP^®. A multiple linear regression model was used, adopting a statistical significance level of 5%, to analyze the correlation between age, SES, and performance on the receptive and emissive vocabulary tests.

Results

In the ABEP questionnaire, participants were classified mostly into social level C (63.3%), followed by levels B (26.6%) and D (10%). The preschoolers investigated presented emissive and receptive vocabulary adequate for the age groups. No statistically significant difference was found for the variables age and SES regarding emissive and receptive vocabulary. Higher test scores were observed with increased age and SES, for social levels “B” compared with “D” and for “C” with “D”.

Conclusion

The variables age and socioeconomic status influenced the performance on emissive and receptive vocabulary tests in the study group.
