Questionnaires and web tests are an essential tool in research in cognitive psychology, especially when participants can be reached independently time in their particular home. They can be a fast and easy way to collect data, which can be useful for speeding up analysis and reducing transcription problems (Couper, 2150; Kocsis, 2004).

The choice of questionnaire style is an important area of the data collection process. A lot of questionnaires are designed to capture free-form text, which are often transcribed by hand or taped in the laboratory (Couper, 2000). Others happen to be multiple-page patterns that present questions on one site and only show the next web page when the previous is finished.

An essential feature of the multiple-page design is that it makes for control over both equally question purchase and the time allowed to solution each dilemma. This is important for controlling to get skip patterns that cunning respondents can use to vary their reactions.

Moreover, it will be possible to provide an increased level of fulfillment to respondents, which might encourage them to preserve answering all survey problems. This would, in turn, minimize item and just a few non-response and unit non-response.

Edition of controlled and organic experiments to the Internet has encountered some challenges, and it is necessary to carefully schedule experiment design and message to take these into account. Specifically, it is crucial to manage for individual attention during the experiment (see below, Collecting top quality data in web-based experiments).
