Child-caregiver interaction in two remote Indigenous Australian communities

Area of Science:

• Sociolinguistics
• Language Acquisition
• Indigenous Australian Studies

Background:

• Remote Indigenous Australian communities are experiencing language shift from traditional languages to local creole varieties.
• Understanding child-caregiver interactions is crucial for analyzing language shift dynamics.
• Previous research often overlooks multilingual practices in non-Western, non-middle-class contexts.

Purpose of the Study:

• To investigate language input and productive language in preschool children within two remote Indigenous Australian communities.
• To analyze changes in adult input and child language development over approximately two years.
• To explore the role of child-caregiver interactions in language shift processes.

Main Methods:

• Longitudinal study design with data collected at two time points, two years apart.
• Focus on language input from primary caregivers and productive language of preschool children.
• Analysis of mean length of turn (MLT), MLT ratio (conversational load), and mean length of utterance (MLU) for morphosyntactic complexity.

Main Results:

• Local creole varieties (Fitzroy Valley Kriol and Wumpurrarni English) are the preferred communication codes.
• Tennant Creek showed increased turn length and morphosyntactic complexity in children and caregivers at Time 2.
• Yakanarra exhibited more variable turn length and decreased caregiver morphosyntactic complexity at Time 2.

Conclusions:

• The study provides detailed insights into multilingual practices in Yakanarra and Tennant Creek.
• Findings illuminate diachronic variations in children's language and linguistic input.
• Contributes to understanding normative language development in multilingual, non-Western contexts.
