Questionnaires and web tests are an essential tool in research in cognitive psychology, especially when members can be reached independently time in their own home. They may be a fast and simple way to get data, that could be useful for accelerating analysis and reducing transcription errors (Couper, 2150; Kocsis, 2004).

The choice of questionnaire design is an important part of the data collection process. A lot of questionnaires are made to capture free form text, that is transcribed manually , or taped in the lab (Couper, 2000). Others happen to be multiple-page patterns that present questions on one webpage and only show the next webpage when the earlier is finished.

An important factor feature of the multiple-page design is the fact it allows for control over the two question buy and the period allowed to response each question. This is important for controlling for skip patterns that devious respondents can use to change their replies.

Moreover, it will be possible to provide a heightened level of satisfaction to respondents, which might encourage them to retain answering all survey problems. This would, in return, minimize item and partial non-response and internet-based.org/ unit non-response.

Variation of handled and healthy experiments online has encountered some conflicts, and it is important to carefully strategy experiment style and model to take these types of into account. For example, it is crucial to control for participator attention during the experiment (see below, Collecting high quality data in web-based experiments).
