Abstract
Age of acquisition (AoA) ratings made on a 1-7 scale for 3,000 monosyllabic words were obtained from 32 participants across four blocks of 750 trials (two blocks of 750 trials were completed in each of 2 days). These results, as well as those of the regression analyses and reliability and validity measures that were originally reported in Cortese and Khanna (2007), are summarized here. Here, we also report high interblock correlations across items, indicating that participants were consistent in their ratings across blocks. The norms for the 3,000 words are important for researchers interested in word processing and may be downloaded from the Psychonomic Society's Norms, Stimuli, and Data archive at www.psychonomic.org/archive.
