Abstract

|
|
Objectives: The study examined communicative behaviors and language abilities of 18- to 24-month-old toddlers according to maternal linguistic input types.
Methods: The study was conducted with 40 participants: 20 toddlers age 18?24 months whose overall development was within a normal range for DEP (Developmental Assessment for the Early Intervention Program Planning) and ?1 standard deviation for SELSI (Sequenced Language scale for Infants), and 20 mothers of the toddlers. We analyzed a 10-minute video that recorded interactive play and reading with the toddlers and mothers and performed SELSI and K M-B CDI (Korea MacArthur-Bate Communicative Development Inventory) to evaluate the toddlers' language abilities.
Results: First, there was no significant difference between communicative behaviors and language abilities according to mothers' linguistic input types in play and reading situations. However, we were able to distinguish maternal linguistic input types as a referential-expressive type in an interaction situation with the toddlers and mothers. Second, we examined a relation between communicative behaviors and language abilities according to maternal linguistic input types.
Conclusion: The study reveals that appropriate harmony brings a positive effect on communicative behaviors and language abilities, as opposed to only one type of input (either the mother referential type where the linguistic input type is oriented for mothers or the toddler-oriented expressive type). The study demonstrates clinical significance by suggesting the necessity of parental education to promote communication and language development for toddlers and mothers must be included in the early selection, diagnosis, and intervention for toddlers at risk for language disorders.
