Researchers trained small GPT-2 models on naturalistic child speech data and synthetic child-directed dialogue to investigate the impact of data quantity, source, and diversity on language model learning. They found that models specialized in predicting specific children's language environments, with lexical and distributional patterns being key drivers of this specialization. Training on data from multiple children improved prediction of pooled language but not necessarily grammatical benchmarks, and naturalistic versus synthetic inputs yielded different grammatical and lexical-semantic patterns.
