Objectives: Using communicative gestures are one of the related factors of language development in toddler periods. The purpose of this study was to examine communicative gestures in toddlers with and without developmental language delay (DLD) and their relations to language development.
Methods: The participants were 10 toddlers with DLD, 10 typically developing chronological age-matched toddlers (CA-matched group), and 10 typically developing language age-matched toddlers (LA-matched group). Communicative gestures were measured with a specific coding scheme consisting of deictic, representational, and conventional gestures in behavior sampled through the Communication and Symbolic Behavior Scales Developmental Profile (CSBS DP) and free play for 5 minutes.
Results: The results showed the following. The DLD group produced a significantly lower frequency of communicative gestures than the CA-matched group, however there was not a significant difference in the LA-matched group. Among the three types of gestures the DLD group showed a significant difference from the CA-matched group only in deictic gestures. The DLD group revealed significantly lower frequency in pointing and giving deictic gestures than the CA-matched group. The total frequency of gestures and frequency of deictic gestures were positively correlated to receptive and expressive language age as measured by the Sequenced of Language Scale for Infants (SELSI) in the DLD group and the LA-matched group, however they were negatively correlated to expressive vocabulary measured by the Korea MacArthur-Bates Communication Development Inventory (K M-B CDI) in the CA-matched group.
Conclusion: We discuss the relationship between communication gestures and DLD based on these results.
