Thinking aloud is widely used for usability evaluation but generally in a relaxed way that conflicts with the prescriptions of the classic model for obtaining valid verbalizations of thought processes. We investigate whether participants that think aloud in the classic or relaxed way behave differently compared to performing in silence. Results indicate that whereas classic thinking aloud has little or no effect on behaviour apart from prolonging tasks, relaxed thinking aloud affects behaviour in multiple ways. During relaxed thinking aloud participants took longer to solve tasks, spent a larger part of tasks on general distributed visual behaviour, issued more commands to navigate both within and between the pages of the web sites used in the experiment, and experienced higher mental workload.
