Elsevier believes that individual authors should be able to distribute their AAMs for their personal voluntary needs and interests, e.g. posting to their websites or their institution's repository, e-mailing to colleagues. However, our policies differ regarding the systematic aggregation or distribution of AAMs to ensure the sustainability of the journals to which AAMs are submitted. Therefore, deposit in, or posting to, subject-oriented or centralized repositories (such as PubMed Central), or institutional repositories with systematic posting mandates is permitted only under specific agreements between Elsevier and the repository, agency or institution, and only consistent with the publisher's policies concerning such repositories. Voluntary posting of AAMs in the arXiv subject repository is permitted.

AbstractThe Less is More hypothesis suggests that one reason adults and children differ in their ability to learn language is that they also differ in other cognitive capacities. According to one version of this hypothesis, children's relatively poor memory may make them more likely to regularize inconsistent input Newport, 2005, 2009). This paper reports the result of an experimental and computational investigation of one aspect of this version of the hypothesis.A series of seven experiments in which adults were placed under a high cognitive load during a language-learning task reveal that in adults, increased load during learning (as opposed to retrieval) does not result in increased regularization. A computational model offers a possible explanation for these results. It demonstrates that, unless memory limitations distort the data in a particular way, regularization should occur only in the presence of both memory limitations and a prior bias for regularization. Taken together, these findings suggest that the difference in regularization between adults and children may not be solely attributable to differences in memory limitations during learning.
