Testing: 5 seconds
TL;DR
First impression test where users see an interface for 5 seconds and then answer questions about what they remember and perceived.
Detailed description
The 5-Second Test is a quick quantitative methodology that evaluates first impressions by showing an interface for exactly five seconds, followed by questions about what users remembered, understood, or perceived. This technique measures the effectiveness of immediate visual communication, information hierarchy, and clarity of purpose, simulating real quick-scanning behavior in digital contexts. Research demonstrates its value for optimizing landing pages, main screens, and critical navigation elements (Nielsen Norman Group). It is especially effective for validating whether the interface instantly communicates its main function and captures attention on the most important elements.
