Listeners rely on co-occurrence frequencies between verbs and syntax—verb biases—to disambiguate sentences with ambiguous structure (e.g., Feel the frog with the feather). Listeners learn new verb biases from exposure to verb-structure pairings, indicating syntactic representations are malleable. However, given age-related declines in relational memory and syntactic priming in production, we ask: Does aging impair syntactic co-occurrence learning? We find that (1) adults use verb bias to guide interpretation across ages, however (2) biases appear to converge towards Equi-bias with aging. Finally, (3) when exposed to new pairings of verbs and structures, adults of all ages update verb biases.
