When Does Forgetting Become Accelerated? The Search for Operational Cut-offs on the Rey Auditory Verbal Learning Test Across the Adult Lifespan

This study aims to conduct a meta-analysis of data obtained from cognitively healthy individuals who completed the Rey Auditory Verbal Learning Test (RAVLT), focusing on performance at standard delayed recall intervals (10–30 minutes) and at one week. The primary objective is to estimate normative reference values for long-term recall performance and to quantify the typical magnitude of forgetting between 30 minutes and one week. These aggregated estimates will be used to explore data-driven thresholds that may inform the identification of accelerated long-term forgetting in clinical populations.
