B&C Tuesday Seminar “From Lexical Selection to Articulation Across the Lifespan”

30.04.2024 12:15 – 13:15

Abstract
Speaking involves selecting and producing about 150 words per minute, at least in
young adult speakers, but speed of word selection and production follows a Ushaped/
bell-shaped curve from childhood to ageing adults. After introducing the
current state of the art on the brain dynamics of the mechanisms underlying referential
and inferential word production in typical young adults (de Zubicaray & Piai, 2019;
Indefrey, 2011; Laganaro, 2023), I will discuss the changes underlying language and
speech production across the lifespan. In particular, based on behavioral and EEG/ERP
studies invovling school-age children, adolescents and different adult age groups, I will
show that (1) word production processes become adult-like only in adolescence both at
the level of lexical selection (Atanasova et al, 2021;2022) and of motor speech
processes (Lancheros et al., 2023), and (2) neurophysiological modifications precede
the behavioral decline in word production in older adults (Krethlow et al., 2024), in line
with the interpretation that the lexical-semantic reorganization in mid-adulthood
influences the maintenance of language skills longer than for other cognitive functions.
