This study investigated therelationship between working-memory (WM) spanand writing performance in three age groups(mean of ages of 15, 30, 77 years). Asexpected, older adults' performance wasinferior to younger adults on measures ofverbal and visual-spatial WM and structuralcomplexity in writing. More important, WM spanmoderated structural complexity in writingacross age and those effects remainedsignificant when short-term memory, readingcomprehension, word knowledge, spelling andhandwriting speed were partialed from theanalysis. Overall, the results support thenotion that age-related changes in textgeneration are moderated by limitations in ageneral WM system.
