Major life events as drivers of perceived linguistic change across adulthood

Abstract This article is the first to quantify the interindividual effects of different major life events (MLEs) on retrospective perceptions of individual-level linguistic change across the adult lifespan. In this cross-sectional study, 701 German-speaking participants from Austria completed an online survey measuring the extent to which MLEs in the educational, occupational, and personal domain are associated with perceived changes in productive and affective-attitudinal aspects of the sociolinguistic repertoire. Bayesian modeling revealed that events such as beginning a tertiary degree, entry into the workforce, and retirement were perceived to impact participants’ varietal use. Overall, however, affective-attitudinal factors such as dialect identity appear to be more readily susceptible to perceived MLE-related change. These results help pave a new path for variationist agendas that approach lifespan linguistic change not as a result of chronological age, but rather as a phenomenon influenced by individual experiential factors complexly intertwined with the process of aging.
