The aim of this study was to examine how the bilingualism interacts with memory functioning in old age. Using data from the Betula study, the performance of 334 bilinguals and 170 monolinguals was compared on episodic and semantic memory tasks at two measurement occasions. The participants were categorized into three age groups: middle-aged (35-50 years old), young-old (55-65 years old), and old-old (70-80 years old). Nine episodic (recall and recognition) and five semantic (knowledge and fluency) tasks were selected and used in this study. The results revealed a bilingual advantage in all memory tasks. It was also found a greater age deficit in episodic memory, especially for recall than for recognition, and at follow-up. The performance on semantic memory tasks indicated an increase in knowledge up to age 65 and thereafter a decrease. These findings suggest that bilingualism may boost older adults’ memory performance.
