Abstract
</SectionTitle>
    <Paragraph position="0"> A new account of parameter setting during grammatical acquisition is presented in terms of Generalized Categorial Grammar embedded in a default inheritance hierarchy, providing a natural partial ordering on the setting of parameters. Experiments show that several experimentally effective learners can be defined in this framework.</Paragraph>
    <Paragraph position="1"> Ew)lutionary simulations suggest that a lea.rner with default initial settings for parameters will emerge, provided that learning is memory limited and the environment of linguistic adaptation contains an appropriate language.</Paragraph>
