Questionnaires and web experiments are analysis methods that use the internet as a means to collect info and are thus often used in place of traditional lab-based trial and error designs. They’ve been around since the times of the World Wide Web (World Huge Web, short: web) and were able to develop rapidly seeing that the Internet progressed and became more widely available (Skitka & Sargis, 2006).
Internet questionnaires and web trials are useful meant for collecting huge participant crowded at lessen administrative costs than can be possible within a lab. Even so, these positive aspects are often counterbalanced by troubles that can happen when using the internet as an experiment place. Birnbaum (2004) highlights advantages and disadvantages of online courses some standard pitfalls, which include incorrect code and erroneous data collection due to the approach HTML forms work (e. g., determining the same varied brand to form elements, for example , into a questionnaire item asking about sex and one requiring sex frequency).
Other challenges can also occur, including drop out and differences in motivation between individuals. The latter may be particularly troublesome because, when pointed out by Reips (1999, 2002b), it might be possible to interpret between-condition effects however the same individuals were subjected to distinctive stimuli in the same experiment.
Fortunately, many techniques and detailed solutions are available to stop these potential problems and perhaps to turn them in to advantageous features of web testing. The software tool OpenSesame, for example, makes it easy to set up and manage complex behavioral experiments via the internet without the need for specialized programming abilities.
