Abstract

This chapter provides an overview of age-related changes and stabilities in numerical cognition. For each component of numerical cognition, we review changes in participants’ performance during normal and pathological aging in a wide variety of tasks. We discuss both behavioral and neural mechanisms underlying these performance variations. Moreover, we highlight the importance of taking into account strategic variations. Indeed, investigating strategy repertoire, selection, execution, and distribution enables to determine sources of aging effects and individual differences in numerical cognition. Finally, we discuss potential future research to further our understanding of age-related changes in numerical cognition.
