Think aloud

This is a data elicitation method or protocol borrowed from cognitive psychology that traditionally has applications in psychological and educational research on cognitive processes . It is mainly used in usability research and in user interface design (e.g. usability testing of prototypes). The method consists of collecting think-aloud protocols (instructing subjects to solve a problem while stating directly what they think) and analysis and interpretation of these protocols. This provides a model of the cognitive processes that took place so and an insight into the way research subjects perform tasks .
