We examined the extent to which prior knowledge about nutrition moderates age differences in remembering newly learned nutrition information. Younger and older adults with varying levels of knowledge read an article on fats and cholesterol and then completed a memory task. Participants responded to statements that were-or were not-presented in the text, which enabled us to examine memory accuracy overall as well as hits and memory errors. Results showed age differences were present in the low-knowledge group but not in the high-knowledge group. Findings illustrate the importance of knowledge for older adults' memory for health information.
