Expectation-driven shifts in perception and production

While phonetic convergence has been taken as evidence for tight perception-production links, attempts to correlate perceptual adjustments with production shifts have been inconsistent, and the existence of expectation-driven convergence further complicates our understanding of this relationship. Here, we report the results of a go/no-go lexical decision task showing that expectation-driven perceptual shifts occur toward the same stimuli that has previously been shown to elicit expectation-driven convergence. We also replicate previous expectation-driven convergence results in production using the Word Naming Game [from Wade (2022). Language 98(1), 63-97]. However, we fail to find evidence that individuals' expectation-driven shifts in perception correlate with those in production. Findings are discussed in terms of implications for the role of expectations on linguistic behavior and the relationship between perception and production.
