Howard S. Hoffman (May 23, 1925 – August 31, 2006) was an American experimental psychologist. Hoffman's work on imprinting, the startle reflex, and memory were particularly influential and earned him an international reputation. He published hundreds of papers as well as a book about the experience of being a scientist, Amorous Turkeys and Addicted Ducklings: A Search for the Causes of Social Attachment.
