Although there is good evidence for implicit learning of associations between forms, little work has investigated implicit learning of form‐meaning connections, and the findings are somewhat contradictory. Two experiments were carried out using a novel reaction time methodology to investigate implicit learning of grammatical form‐meaning connections. Participants learned four novel articles but were not told about a critical semantic factor that determines agreement with the accompanying noun. Their task was to indicate as quickly as possible which of two pictures was being referred to by an article‐noun combination. The measure of learning was whether response times would slow down when the agreement rule was violated (i.e., when the wrong article was used for the picture being referred to). Experiment 1 revealed such an effect when articles correlated with noun animacy, even for participants with no reported awareness of this regularity. In Experiment 2 no such effect was obtained when the regularity concerned the relative size of two objects. It is concluded that grammatical form‐meaning connections may be learned implicitly, but learning is constrained by the nature of the meaning involved. It is argued that concepts are differentially available to implicit language learning processes.

The traditional implicit learning literature has focused primarily on the abstraction of statistical regularities in form-form connections. More attention has been recently directed toward the implicit learning of form-meaning connections, which might be crucial in the acquisition of natural languages. The current article reports evidence for implicit learning of a mapping between a novel set of determiners and thematic roles, obtained using a newly developed reaction time methodology. The results conclude that contextually derived form-meaning connections might be implicitly learned.

We report three experiments that explore the effect of prior linguistic knowledge on implicit language learning. Native speakers of English from the United Kingdom and native speakers of Cantonese from Hong Kong participated in experiments that involved different learning materials. In Experiment 1, both participant groups showed evidence of learning a mapping between articles and noun animacy. In Experiment 2, neither group showed learning of a mapping between articles and a linguistically anomalous concept (the number of capital letters in an English word or that of strokes in a Chinese character). In Experiment 3, the Chinese group, but not the English group, showed evidence of learning a mapping between articles and a concept derived from the Chinese classifier system. It was concluded that first language knowledge affected implicit language learning and that implicit learning, at least when natural language learning is concerned, is subject to constraints and biases.
