question-asking protocol – πρωτόκολλο ερωτήσεων

in contrast to the think aloud protocol, in which users are asked to speak freely about their thoughts without prompting from the tester, in the question-asking protocol, the tester explicitly asks the user questions during the user testing session, to see how the screens are being interpreted and to ask the user to react to parts of a design that the user may otherwise be neglecting.
