Age of acquisition (AoA) ratings based on a 1-7 scale for 3,000 disyllabic words were obtained from 32 participants. We demonstrate that these estimates are both reliable and valid. These estimates add to those collected on monosyllabic words and are of value to researchers interested in factors that contribute to word processing. They also can be used in regression analyses on measures obtained from large databases, and can be used in conjunction with imageability ratings for the same word corpus to differentiate AoA from imageability.
