Individual Differences in Language Processing: Phonology

Individual variation is ubiquitous and empirically observable in most phonological behaviors, yet relatively few studies aim to capture the heterogeneity of language processing among individuals, as opposed to those focusing primarily on group-level patterns. The study of individual differences can shed light on the nature of the cognitive representations and mechanisms involved in phonological processing. To guide our review of individual variation in the processing of phonological information, we consider studies that can illuminate broader issues in the field, such as the nature of linguistic representations and processes. We also consider how the study of individual differences can provide insight into long-standing issues in linguistic variation and change. Since linguistic communities are made up of individuals, the questions raised by examining individual differences in linguistic processing are relevant to those who study all aspects of language.
