Gervain et al. discuss both behavioral and neurophysiological AGL studies that investigate rule and structure learning processes in infants. The paper provides an overview of all the major AGL paradigms used to date to investigate infant learning abilities at the level of morpho‐phonology and syntax from a very early age onwards. Gervain et al. also discuss the implications of the results for a general theory of natural language acquisition.

Learners exposed to an artificial language recognize its abstract structural regularities when instantiated in a novel vocabulary (e.g., Gómez, Gerken, & Schvaneveldt, 2000; Tunney & Altmann, 2001). We asked whether such sensitivity accelerates subsequent learning, and enables acquisition of more complex structure. In Experiment 1, pre-exposure to a category-induction language of the form aX bY sped subsequent learning when the language is instantiated in a different vocabulary. In Experiment 2, while naíve learners did not acquire an acX bcY language, in (...) which aX and bY co-occurrence regularities were separated by a c-element, prior experience with an aX bY language provided some benefit. In Experiment 3 we replicated this finding with a 24-hour delay between learning phases, and controlled for prior experience with the aX bY language's prosodic and phonological characteristics. These findings suggest that learners, and the structure they can acquire, change as a function of experience. (shrink)

We found a direct relationship between variation in informants' grammaticality intuitions about pronoun coreference and variation in the same informants' use of a clause segmentation strategy during sentence perception. It has been proproposed that ‘c‐command’, a structural principle defined in terms of constituent dominance relations, constrains within‐sentence coreference between pronouns and noun antecedents. The relative height of the pronoun and the noun in the phrase structure hierarchy determines whether the c‐command constraint blocks coreference: Coreference is allowed only when the complement (...) structure containing the noun is attached higher than the pronoun. We collected informants' judgments on pronoun‐noun coreference in which the noun antecedent was contained in a complement structure dominated by either the Sentence‐node (S‐node) (higher than the pronoun) or the Verb‐phrase‐node (VP‐node) (not higher than the pronoun). We also assessed each informant's perceptual clause‐closure tendency using an auditory word‐monitor paradigm. Informants who strongly segmented clauses in the perceptual task did not differentiate between an S‐ and VP‐attachment of sentence complements, as revealed in their coreference judgments, but rather appeared to attach all sentence complements to the S‐node. Informants with relatively weak perceptual segmentation differentiated their coreference judgments according to the node attachment of the complement structure. These results indicate that the linguistic universal controlling within‐sentence coreference applies to the perceptually available structure for a sequence, not to its pure linguistic structure. Hence, linguistic intuitions result from the interaction of three independent faculties: language‐specific knowledge, perceptual processes, and linguistic universals. (shrink)
