Age and Discourse Task Independently Influence Disfluency Production.

PURPOSE Aging is often associated with increased difficulty in speech production (e.g., increased word-finding difficulties and disfluencies), as well as with broader cognitive changes such as declines in executive function (EF) and greater sensitivity to task constraints. However, how both EF and task constraints cont...

Multilingual experience and cognitive control shape lexical competition in non-native word production: An fMRI study

During production, multilinguals face increased lexical competition within and across languages, demanding cognitive control. This study investigated how multilingual experience—indexed by proficiency and usage—modulates the influence of trait-level (via control tasks) and state-level (using a Stroop-embedded picture...
