AI models learn Spanish morphome as lexical abstraction, not generalization

Researchers have investigated how character-level transformers learn complex morphological patterns, specifically the Spanish L-shaped morphome. Their study, which involved probing five different transformer architectures, revealed that these models encode the pattern itself rather than just its visible alternations. The encoding is localized to the stem-final consonant position and appears to be item-specific, suggesting that models store the morphome as a lexical abstraction that can reproduce the pattern but does not generalize it like human language acquisition.

IMPACT Reveals limitations in AI's ability to generalize linguistic patterns, highlighting the difference between learned abstraction and human-like understanding.
