Jerome Hergueux and Nicolas Jacquemet developed an "online laboratory" to compare social preferences and risk aversion online and in person. They administered a risk aversion assessment, Public good game, a Trust game, a Dictator game, and an Ultimatum game to groups both online and in a lab as a way of assessing the internal validity of web-based experimentation in economics. An online field experiment conducted on 61 million Facebook users tested whether receiving information about voting, polling places, and the voting behavior of one's friends led individuals to seek out political information, influenced political self-expression, and changed real-world voting behavior.
Web-based experiments have particular salience in studies of how online communities operate.

Experimenting on the World WideWeb. Paper presented at the Society for Computers in Psychology conference, Chicago. To save space and trees , the authors have made a great deal of information available to you electronically via the Internet. Terms used in the book unique to this type of research e. The book has three sections. The first deals with general questions such as do the results of Web experiments agree with those of laboratory experiments?
Who are the people who volunteer to participate via the Internet? What were the developments that led to the first Web studies and what did the early Web researchers experience? What are the methodological considerations in doing research by "remote control?

Because the Internet provides a means to reach large and diverse samples, it seems ideally suited for these purposes. The third section covers advanced computer techniques that allow for greater control of Internet experiments. These include the dynamic creation and display of graphics, randomization, and timing in experiments such as those in cognitive experimental psychology. In addition, methods for scoring and feedback on surveys or tests, tracking of participants, security, and saving of data on the server are discussed. This chapter provides a preview of several of the issues and questions that are themes of this book: The chapter also describes a program of research in decision-making.
The appendix of Chapter 1 illustrates how experiments that might be done by paper-and-pencil methods can be easily conducted using the technique of forms available in HTML Hyper Text Markup Language, see glossary.
The chapter reviews experiments on decision making that were done with three samples, one conducted with undergraduates in the laboratory, one recruited from experts in judgment and decision making, and another recruited by Web sites that advertise games and drawings with prizes. The decision-making experiments of this chapter can be viewed at URL [ http: Krantz and Dalal review studies that assess the validity of Web experiments.

Whereas laboratory studies typically use a small, homogeneous sample tested in controlled conditions, the Internet study typically uses a large, heterogeneous sample tested in less well-controlled conditions. Krantz and Dalal define validity in terms of the correspondence of results between experiments conducted via the Web and those done in the laboratory. The trend emerging from the early research on this problem is that Internet studies yield the same conclusions as studies done in the lab.
Musch and Reips review the brief history of experimentation on the WWW. Musch and Reips surveyed those who conducted the first Web experiments and report their results in their chapter. Most of those who responded to the survey concluded that their research projects were successful and planned to continue research via the Web.
Reips reviews methodological issues in Internet research. Reips reverses the definition of validity given by Krantz and Dalal, arguing that one should be more skeptical of traditional laboratory research than of Web-based research, because of certain problems of traditional research.
Web-based experiments - Wikipedia
For instance, because large and diverse samples are obtained from the Web, one can separately analyze a research question in each demographic sub-sample, to ensure that conclusions that are found with year-old college students also hold in other demographic groups. The chapter reviews pros and cons of Web research, concluding that advantages of Internet research outweigh the disadvantages. Reips also describes techniques to deal with potential problems, illustrating certain issues with data from his Web Experimental Psychology Lab, URL [ http: This site, first established at Tuebingen, is now in Zurich.
The site contains a number of Web experiments, an archive of past experiments, and commentaries on the Web experiment method. As such, learning about experiments on the internet will be of vital interest to all research psychologists. Psychological Experiments on the Internet is divided into three sections.
Section I discusses the history of web experimentation, as well as the advantages, disadvantages, and validity of web-based psychological research. Section II discusses examples of web-based experiments on individual differences and cross-cultural studies. Section III provides readers with the necessary information and techniques for utilizing the internet in their own research designs.
