Shownotes

...and now for another Human Factors Minute!

Think aloud protocol: Also known as "concurrent verbal protocol", is the process of asking a user to execute a series of tasks or use technology, while continuously verbalizing their thoughts so that a researcher can gain insights into the users' analytical process.

This method can be useful for identifying design flaws that do not affect task performance, but may have a negative cognitive effect on the user.

Additionally, this technique can also be useful for utilizing experts to better understand procedural knowledge of the task in question.

This practice is less expensive than focus groups, but tends to be more specific and subjective.

This has been another Human Factors Minute!
