AI and Behavioral Data Identify When Children Start Using Language Creatively


A study by researchers from the University of Chicago explored when children start producing novel language combinations, like using “a” and “the” for the same noun, beyond what they’ve heard. Using behavioral observations and a computational model, they determined that English-speaking children begin creating these novel combinations around 30 months of age. The study combined data from 64 children and a predictive computer model to confirm the findings. This approach helps understand how children learn language, including the role of linguistic input and how children’s ability to create language structures develops.


A recent study published in Proceedings of the National Academy of Sciences utilized behavioral observations and computational models to determine when English-speaking children begin using language independently, rather than mimicking others. Researchers from the University of Chicago pinpointed this milestone—when children create determiner-noun combinations they’ve never heard before, such as “a dog” after hearing “the dog”—at around 30 months of age.

Key Findings:

  1. Behavioral Observations:
    • Researchers recorded 64 children interacting with their caregivers every four months, analyzing their language patterns.
    • At approximately 30 months, children started using “a” and “the” creatively with nouns, forming combinations not modeled by their caregivers.
  2. Computational Modeling:
    • A generative computer model was trained on parental language data to simulate a child’s language learning.
    • The model accurately predicted the same timeline, confirming the observed behavior.

Importance of Mistakes in Language Learning:

Children’s language errors, such as saying “I eated,” indicate their grasp of grammatical rules. Similarly, their creative use of determiners shows an understanding of language patterns.

Implications for Linguistics and Beyond:

  • Understanding Input Needs: The findings help explore how much linguistic input is necessary for children to grasp complex language structures.
  • Insights from Homesigners: Studying deaf children who create their own gestural language can reveal universal principles of language development.

By combining computational modeling and behavioral data, this research paves the way for deeper understanding of how children learn and use language independently.
