The high hurdle technique intends to move dropout to the beginning of an Internet-based study (Reips, 1997, 2000, 2002, but see Stieger &amp; G&ouml;ritz, in press). Reading of very long instructional text, for example, may trigger early drop out in those participants, who are not sufficiently motivated to complete the whole experiment. A technical high hurdle artificially delays the loading of web pages at the beginning of the experiment. WEXTOR uses a set of JavaScript functions on the first three web pages of an experiment to achieve this goal.
