Twenty years of Inhibition of return (IOR) research?!?! What's that?

In case you didn't know, inhibition of return is the phenomenon where a stimulus is presented in the same position on two sequential trials vs. two different locations (e.g., left then right). It has been shown that participants are slower and less accurate to respond to the first sequence (two same locations) than the second (two different locations). It's interesting to me because this seems counterintuitive to the spreading activation/priming notions, which I think have been a limiting metaphor for thinking about many issues in cognitive science for at least the last 30 years. The current issue of Cognitive Neuropsychology is a special issue on IOR and including a good introduction by Juan Lupiáñez as well as an article he co-authors with Ana Chica (first author).
