The current study tests the hypothesis that language comprehension is, in part, influenced by language exposure, and the biases that people develop are related to the frequency of exposure to different linguistic input, like, for instance, pronoun coreference. As comprehenders filter the linguistic input they encounter, we ask, what is the impact of encountering different kinds of input on the representations that comprehenders form? We test this question by examining comprehenders' ambiguous pronoun comprehension. Using an adaptation paradigm (Johnson and Arnold, 2022), we manipulated the kind of pronoun coreference structure (nonsubject or subject) to which participants were exposed, and critically, we manipulated the distribution. In experiment 1a, participants were exposed to a distribution that was uniform (100% subject or nonsubject exposure) and in experiments 1b (75% subject or nonsubject and 25% opposite referential exposure items), 2a (75% subject or nonsubject and 25% one referent items), and 2b (75% subject or nonsubject and 25% uninformative items), participants were exposed to a distribution that was mixed. We tested if the amount of exposure (100% vs. 75%) affected pronoun comprehension and whether the other 25% of items in the distribution would compete with the most frequent structures and affect learning. Results demonstrated that comprehenders learned the most frequent pattern across all distribution types. We did not find any competition effects.
