The present study examined whether semantic activation occurs for LEET stimuli, where digits were used as parts of words (e.g., "R34D1NG" instead of "READING"). Previous studies (e.g., Perea et al., 2008) using behavioral measures have suggested that LEET stimuli result in semantic activation because of priming effects. We attempted to provide converging operations for this result by using a more direct, electrophysiological measure: the N400 effect elicited by words (a measure of whether participants detected a mismatch between the word and the current semantic context). This N400 effect can occur only if a word has been identified and processed up to the semantic level. Participants performed a categorization task in the present experiment"”determining whether a word or LEET stimulus was related or unrelated to a given category name. We found that LEET stimuli produced an N400 effect similar to that for regular words, suggesting that LEET words result in access to meaning in a similar manner to words presented in consistent uppercase letters.
