Questionnaires and web experiments are an important tool in research in cognitive psychology, especially when members can be reached independent time in their own home. They may be a fast and simple way to collect data, and this can be useful for speeding up analysis and lowering transcription mistakes (Couper, 2k; Kocsis, 2004).

The choice of set of questions design is an important element of the data collection process. A few questionnaires are made to capture free-form text, and this can be transcribed by hand or recorded in the laboratory (Couper, 2000). Others will be multiple-page models that present questions on one web page and only show the next page when the earlier is finished.

An integral feature for the multiple-page design is the fact it permits control over both question purchase and the time allowed to response each question. This is necessary for controlling to get skip patterns that devious respondents can use to vary their reactions.

Moreover, it will be easy to provide a higher level of satisfaction to respondents, which might encourage them to continue answering all of the survey issues. This would, therefore, minimize item and part non-response and product non-response.

Difference of taken care of and organic experiments to the Internet has encountered some conflicts, and it is essential to carefully strategy experiment style and decryption to take these into advantages and disadvantages of questionnaires account. Especially, it is crucial to regulate for player attention during the experiment (see below, Collecting high-quality data in web-based experiments).
