Table 1_A methodological protocol for multimodal profiling of conversational abilities in

A methodological protocol for an age-stratified cross-sectional observational study involving 180 children aged 4-6. The protocol, authored by Cai Wang and last updated in May 2026, describes a multimodal framework for assessing conversational abilities in Mandarin-speaking children with and without Developmental Language Disorder.

Use Cases

• Developing culturally adapted assessment tools based on the described multimodal framework.
• Analyzing pragmatic language features like topic maintenance and repair rates based on the primary outcome measures.
• Investigating gesture-speech alignment in child communication based on the annotation tiers.
• Comparing conversational profiles between children with DLD and typically developing peers based on the matched sample design.
• Evaluating the feasibility of multimodal data collection and annotation protocols in linguistic research.

Strengths

• The protocol includes explicit feasibility benchmarks for session completion, recording length, and utterance yield.
• It plans to apply a finalized protocol to a matched sample of 90 children with DLD and 90 typically developing peers.
• The framework integrates multimodal data, including audio-video recordings and annotation tiers for utterance-level features, communicative acts, repairs, turn-taking, and gesture-speech alignment.

Limitations

• The protocol describes a cross-sectional design, which limits longitudinal insights.
• The sample size of 180 children is described as modest.
• The dataset file is a 15.7 KB DOCX document describing a protocol; the actual observational data is not included.
