Martha, I'm not sure if anyone has published data using the PEBL flanker task previously. You might be the first. I modeled it roughly after the Stins 2007 paper:
## John F. Stins, Tinca J. C. Polderman, Dorret I. Boomsma and Eco ## J. C. de Geus (2007). "Conditional accuracy in response ## interference tasks: Evidence from the Eriksen flanker task and the ## spatial conflict task". Advances in Cognitive Psychology 3 (3): ## 389396. http://www.ac-psych.org/download.php?id=63. I would start with that paper to see what DVs they reported. Also, you might look at Eriksen, 1979: ## see Eriksen, C. W., & Schultz, D. W. (1979). "Information processing in ## visual search: A continuous flow conception and experimental ## results". Perception & Psychophysics 25 (4): 249263.
