What is semantic priming?
Semantic priming indicates that activation passes between nodes. Participants are shown two letter strings and must push one button if both are words and another button if one or both are nonwords. When both letter strings are words, response times are faster when the words are semantically related (doctor-nurse) than when they are not (radio-nurse). A straightforward interpretation is that when participants saw the word doctor, the node representing the concept became active and immediately passed activation to all semantically related concepts, including nurse. When participants read the word nurse, the concept representing it was already somewhat active so it was easier for them to identify the word.
