Zusammenfassung
Server-side experiments use the Web server, rather than the participant's
browser, to handle tasks such as random assignment, eliminating inconsistencies
with JAVA and other client-side applications. Heretofore, experimenters
wishing to create server-side experiments have had to write programs
to create common gateway interface (CGI) scripts in programming languages
such as Perl and C++. NetCloak uses simple, HTML-like commands to
create CGIs. We used NetCloak to implement an experiment on probability
estimation. Measurements of time on task and participants' IP addresses
assisted quality control. Without prior training, in less than 1
month, we were able to use NetCloak to design and create a Web-based
experiment and to help graduate students create three Web-based experiments
of their own.
