Gradually increasing context-sensitivity shapes the development of children's verb marking: A corpus study

Area of Science:

• Developmental psycholinguistics
• Child language acquisition
• Corpus linguistics

Background:

• Children often produce grammatical errors, such as omitting verb morphemes (e.g., "She play").
• These errors are increasingly understood as errors of commission, reproducing input patterns without full contextual understanding.

Purpose of the Study:

• To investigate how children overcome verb-marking errors.
• To test the hypothesis that error recovery is linked to developing sensitivity to longer-range linguistic dependencies.

Main Methods:

• A pre-registered corpus analysis was conducted on child language data.
• The study examined the predictive value of context-independent cues (verb identity) and context-dependent cues (subject+verb sequence frequency).

Main Results:

• The relative frequency of unmarked subject+verb sequences significantly predicted error reduction across 2- to 4-year-olds.
• Context-independent verb cues were predictive only in younger children (2-3 years).
• Sensitivity to context, specifically preceding lexical items, increases with age.

Conclusions:

• Children's recovery from verb-marking errors is driven by increasing sensitivity to contextual cues.
• This sensitivity develops progressively, from immediate lexical context to more distant grammatical markers.
