Sensitivity to Morphosyntactic Information in 3-Year-Old Children With Typical Language Development: A Feasibility...

Area of Science:

• Child language acquisition
• Psycholinguistics
• Developmental linguistics

Background:

• Children's understanding of grammatical morphemes, like tense and agreement, is crucial for language development.
• Specific language impairment (SLI) is characterized by difficulties in language acquisition, including inconsistent auxiliary verb use.
• Assessing online comprehension provides insights into real-time language processing in children.

Purpose of the Study:

• To evaluate a novel method for measuring young children's sensitivity to tense/agreement in fronted auxiliaries during question comprehension.
• To investigate whether typically developing 3-year-olds demonstrate awareness of subject-verb agreement in real-time.
• To establish a baseline for future research comparing language processing in typically developing children and those with SLI.

Main Methods:

• Fifteen typically developing 3-year-olds participated.
• Children viewed visual stimuli (pictures of single vs. multiple agents) while listening to questions.
• Their looking patterns were recorded to measure anticipatory eye movements in response to agreeing or non-agreeing auxiliaries (e.g., 'is' vs. 'are').

Main Results:

• Children demonstrated anticipatory looking based on the number information conveyed by the auxiliary verb.
• This indicates sensitivity to subject-verb agreement in the context of questions.
• The findings suggest that the assessment method is feasible and effective.

Conclusions:

• The developed method successfully identified sensitivity to tense/agreement information in 3-year-old children.
• This research provides a foundation for direct comparative studies between typically developing children and children with SLI.
• The findings have implications for understanding the linguistic challenges faced by children with SLI.
