Abstract:There are some influential studies that claim it is possible to measure the perceived usability or perceived aesthetic of a website in less than a second. However these studies do not take into account that there is a difference between perception and judgment. The judgments are used to adjust a website, however, it would be better to improve a website by taking the cognitive processes into consideration. These processes consist of variables such as prototypicality (PT) and visual complexity (VC). These variables were used by Tuch et al. (2012) and Schmettow and Nazareth (2014) to test their influence on judgments. We replicated the experiment by Tuch et al. (2012), which is based on the information-processing model by Leder et al. (2004), to find out if the judgment on the user experience questionnaire (UEQ) is influenced by the early information-processing stages and if the judgment is in line with the fluency model by Schmettow and Nazareth (2014). The experiment consists of four blocks which differ in presentation time (17, 50, 500ms and unlimited time) of the 66 website screenshots. The websites differed in degrees of PT and VC. The linear mixed model analysis reveals that PT and VC did not influence the judgments on UEQ. However, it was found that the explained variance of the final judgment and the other time conditions increases when the presentation time rises and that the information-processing finished quickly. That means that the judgments are influenced by the early information-processing stages but that PT and VC are not involved in the processes. Furthermore, there are no indications that the judgement on UEQ is in line with the fluency model.
