6 Conclusions
</SectionTitle>
    <Paragraph position="0"> Using a probabilistic model of individual acquisition to model a population's language change, we demonstrate the sufficiency and necessity of certain restrictions on individual acquisition. In this way, we provide empirical suport for a proposal about what data children are learning from for syntactic acquisition - the degree-0 unambiguous trigers.</Paragraph>
    <Paragraph position="1"> Future work wil refine the individual acquisition model to explore the conection between the length of the critical period and the parameter in question, including more sophisticated techniques of Bayesian modeling (to replace the current mechanisms of Noise Filter and Batch Learner), and investigate what parameters must be considered to determine if a triger is &amp;quot;unambiguous&amp;quot;. As well, we hope to test the degree-0 unambiguous triger restriction for other parameters with documented language change, such as the los of V2 movement in Midle English (Yang 203, Lightfoot 199, among others). This type of language change modeling  may also be useful for testing proposals about what the crucial data is for phonological acquisition.</Paragraph>
