Method: Subjects perform a lexical decision task in which they must determine is a pair of words are both words. The pairs vary from both non-words, one non-word one word, two unrelated words, and two related words.
Results: RT is the shorter for related words compared to unrelated words.
Conclusion: Semantic priming occurs when recognition of a stimulus is influenced by previous presentation of similar stimuli. When subjects read the first word, the activation spreads to related words, by the time they read the second (related) word, the word has already been activated, making them faster to decide if it is a word.
