This study looks at English preschoolers' parallel production and comprehension of definite and indefinite articles in an Optimality Theory framework. Adults associate the with determined reference and a with non-determined reference, and I wanted to investigate how children's grammar deviates from this pattern in terms of comprehension and production of definite and indefinite articles. In testing 19 preschoolers, I find that children have trouble producing a in the target situation and tend to overuse the, consistent with previous literature, but they were considerably better at producing the in the target situation. In comprehension, I found that children have an adult-like interpretation of the as referring to a previously mentioned referent, but their comprehension of a was at chance. I present an OT analysis of the target grammar and show that children's deviation is due to lack of ability to reason bidirectionally as well having unranked constraints.
