Human neuroimaging research on cognitive aging has brought significant advances to our understanding of the neural mechanisms underlying age-related cognitive decline and successful aging. However, interpreting age-related changes and differences in brain structure, activation, and functional connectivity is an ongoing challenge. Ambiguous terminology is a major source of this challenge. For example, the terms ‘compensation,’ ‘maintenance,’ and ‘reserve’ are used in different ways and researchers disagree about the kinds of evidence or patterns of results required to interpret findings related to these concepts. As such inconsistencies can impede theoretical and empirical progress, we here aim to clarify these key terms and to propose consensual definitions of maintenance, reserve, and compensation.
