The psychology department of the University of Potsdam wants to carry out a trial that examines how human beings control their attention in different environments. Participants of the trial will work on tasks within a survey and their solutions will be analyzed. The survey consists of three parts: the categorization of photos, solving anagrams and the selection of anagrams that will be presented to other participants. This is important in order to avoid the so-called “examiner effect”.
The implementation of the survey will need to be prompt and inexpensive. In addition, the amount of time needed to acquire and question the participants will need to be kept to a minimum.
The university set up the online survey with an external survey tool and, via our self service marketplace, invites a large pool of target-group-specific Clickworkers to participate in the survey.
Numerous Clickworkers answer the questionnaire in a minimum of time. We make sure that every Clickworker can only complete the questionnaire once. The compulsory entry of a code at the end of the survey ensures that the participants must complete the survey to receive their payment.
