תקציר

The aim of this study was to examine whether performance on phonemic and semantic fluency tasks follows similar lifespan trajectories. Data from 1212 Hebrew-speakers aged 5-86 years were analyzed. Both linear and curvilinear quadratic models fit the data, reflecting a general increase in ability with age, as well as an increase followed by a decrease beyond this linear rise. A significant interaction between task type and the curvilinear effect demonstrated differential lifespan patterns of performance on each task. While scores improved similarly on the phonemic and semantic tasks during childhood, late-life decline was more noticeable on the semantic task, possibly due to the unique characteristics of aging-related word retrieval difficulties.
