    Information Integration Theory (IIT) is concerned with how people combine
    information into an overall judgment. A method is hereby presented to
    perform Functional Measurement (FM) experiments, the methodological
    counterpart of IIT, on the Web. In a comparison of Web-based FM
    experiments, face-to-face experiments, and computer-based experiments in
    the lab it is found that the computer-based method is less sensitive to
    experimental manipulations. However, different integration rules can be
    distinguished. The inability to monitor motivation in the unproctored setting
    can partly explain this effect. Consequently it is argued that Web-based
    experiments enable the researcher to test larger groups which enable more
    in-depth analysis of individual differences using single subjects analyses and
    clustering methods.
