Abstract

Psychological studies implementing the World-Wide Web as a data collection medium have traditionally been constrained to data obtained from surveys or from within-subjects comparisons. Common gateway interface (CGI) scripts, however, provide researchers with a means of collecting data for between-subjects comparisons. This paper provides a description of the information flow between the user (subject) and the experimenter by referencing a completed between-subjects assignment CGI. A current online cognitive psychology experiment serves as an example of the utility of CGIs as subject assignment mechanisms. Server-side and client-side scripts are compared for effectiveness at data collection, with these types of designs in mind.
