Task Switching with Flanker distractors paradigm, created by Raphael Geddert (raphael[DOT]geddert[AT]duke[DOT]edu) and Tobias Egner (http://www.egnerlab.org/) at Duke University.
TSF_1.0.0: Original Task Switching Flanker.
TSF_2.0.0: Flanker incongruencies now match the cued task, and flanker proportions are set at 50% congruent and 50% incongruent.
TSF_2.1.0: Flankers now precede targets by 200 ms (adjustable) in order to increase flanker effects.
