the design and procedure for the experiment by McKenzie and Nelson. It is a 2 x 2 between-subjects factorial design, resulting in four experimental conditions. Each condition is represented by one folder containing the Web pages the participants will see in that condition. Every Web page holds the dynamically created scripts that translate into the study procedure and response time measurement. After creating the experimental materials in WEXTOR they can be downloaded in one compressed archive that contains all folders (directories), scripts, and Web pages. WEXTOR contains a description of how to give these pages the "editing finish" and how to configure a Web server to post the pages on the Web (also see Birnbaum & Reips, 2005).
