Event-related potentials reveal rapid verification of predicted visual input

Dambacher, Michael, Rolfs, Martin, Göllner, Kristin, Kliegl, Reinhold, Jacobs, Arthur M. January 2009 (has links)
Human information processing depends critically on continuous predictions about upcoming events, but the temporal convergence of expectancy-based top-down and input-driven bottom-up streams is poorly understood. We show that, during reading, event-related potentials differ between exposure to highly predictable and unpredictable words no later than 90 ms after visual input. This result suggests an extremely rapid comparison of expected and incoming visual information and gives an upper temporal bound for theories of top-down and bottom-up interactions in object recognition.
