Glossary of Terms

InformeDesign’s Glossary of Terms offers basic definitions for research terms that are hyper-linked in the Research Summaries. If you are reading a Research Summary, click on the hyper-linked word or phrase and a small window will open up to display a brief definition.

The Glossary of Terms can also be used as a mini-dictionary for terms regarding design and human behavior and commonly used research terms. Please contact us if you have terms you would like to see added.
