Title Cognitive Probing Methods in Usability Testing – Pros and Cons
Year 2016
Access date 09.06.2016
Think-aloud is one cognitive probing technique often used in usability testing. When think-aloud is applied during the usability testing, the participant is instructed to give a running commentary while performing a usability task. The participant’s verbal commentary can include such things as what he orshe is looking at, reading, thinking, feeling, and doing to answer the questions. Collecting this type of qualitative data is useful because it helps find the root causes of usability problems. This technique is modeled after Ericsson and Simon’s protocol analysis. The technique used in usability testing is very similar to the probing techniques used in cognitive testing which include concurrent and retrospective probing. Cognitive testing is conducted to pinpoint problems in question wording and response options. These two types of probing often overlap in online surveys. Depending upon the purpose of the usability evaluation, we have experimented with a variety of probing methods in usability testing, including retrospective probing, think-aloud, and think-aloud with concurrent probing. This talk will discuss these techniques and their trade-offs in light of the usability evaluation purpose.
