Persistence of negative priming: Steady state or decay?

Responses to recently ignored stimuli may be slower and less accurate than responses to new stimuli. Neill and Westberry (1987) found that such negative priming effects dissipated within a 2-s interval between response and the next stimulus, the response-stimulus interval (RSI). However, experiments by Tipper, Weaver, Cameron, Brehaut, and Bastedo (1991) found negative priming persisted unchanged over RSIs from 1,350 to 6,600 ms. Our experiments...
