This study investigates how the complexity of a web interface influences the perceived cognitive load and user experience among first-time website visitors. The CNN website was used as an example of a visually complex interface, and a minimalist prototype was developed to contrast its design. Twelve participants took part in testing both interfaces by completing a series of tasks, followed by cognitive load questionnaires (NASA-TLX) and semi-structured interviews. The findings show that the minimalist prototype in comparison to the CNN website, was less straining on the mind, as indicated by lower NASA-TLX scores, and was generally perceived as more intuitive and aesthetically pleasing. In contrast, the CNN site was described as overwhelming and visually crowded, although some participants appreciated its variety of content. These results highlight the trade-offs between minimalist and visually complex designs, offering insight for web designers aiming to balance clarity, usability, and informational richness.
