What is the function of the 5-second test in UX?

The function of the 5-second test in UX is to assess users' first impressions of a design. This method involves showing users a design or a webpage for just five seconds, after which they are asked to recall what they saw and their thoughts about it. The goal is to gauge immediate reactions and understand key elements that catch attention, as well as whether the design communicates its intended message effectively.

This approach is valuable because it helps designers to identify whether key information, visuals, or call-to-action elements are clear and engaging. First impressions are critical in user experience design, as users often decide quickly whether to stay on a page or seek information elsewhere. Utilizing the 5-second test allows for quick validation of design effectiveness before investing additional resources into development.
