What is Think Aloud?
Think Aloud (TAP) is a testing method where subjects are required to speak to interact with manual, device or concept. They can discuss how they feel at work and throw problems and solutions aloud as they proceed. Many devices record testing and observers also make notes. This information can provide important feedback to improve the product, understand how people use critical thinking to solve problems, and collect more general information about how people think and behave. The test entity can be given a task such as using a manual to build something or solve problems. Entities can also interact with unknown objects or test things such as computer software and mechanical controls for the device. The researcher tells the subject of the purpose of the test, usually emphasizes that the goal is to collect information as Naturalls as much as possible. They could move from dislike to layout of the handbook to attempt to solve the problem.For example, a participant can be presented a computer and asked to perform a task. The user can talk about trying to find the right program for the task, learn the program controls and search for help from the computer's documentation.
This approach requires a neutral observer who does not comment or integrate during the Think aloud protocol. If there are errors, the tester acknowledges the conditions. For example, users who test a new mobile phone could make all similar errors, suggesting that there is something wrong at the interface; For example, a button that designers think is intuitive can be confusing. Similarly, the documentation in the Set UP and the table can miss the key piece of information that results in a consistent error during testing.
Scientific scientists can use the Think Aloud Protocol to learn more about human knowledge, not necessarily to test the product or set of documentEntation. Increasing understanding of how people solve problems and approach a new environment, can help scientists with tasks such as treatment of patients with cognitive deficits, or develop programs for people with learning disorders. For example, dyslexic subjects can show that the educational program does not work for them as intended.
