What is the English Lexicon Project?

The goal of the English Lexicon Project (ELP) is to collect normative data for speeded naming and lexical decision for over 40,000 words across 1200 subjects at 6 different universities. These data will be integrated into a database along with descriptive characteristics of the words used in the study. Researchers interested in psycholinguistics, human memory, computational modeling, and other fields will find these data useful. For example, researchers will be better equipped to select stimuli, test theories, and reduce potential confounds in their studies.


This project was a collaboration across 6 universities and is supported by a grant from the National Science Foundation to David A. Balota.
