What could indicate a lack of understanding during SFST instructions?

Taking a long time to start the test can suggest a lack of understanding during the SFST instructions. This hesitation may indicate that the individual is struggling to comprehend the directions given or is unsure of what is expected of them. Effective and timely response to such instructions is essential for the SFST process, as it not only serves to gauge the individual's understanding but also their ability to follow the commands accurately.

In contrast, responding too quickly may imply eagerness or an attempt to comply without fully processing what is required, which is different from a clear lack of understanding. Conveying clear eye contact and expressing confidence in performance generally indicate engagement and comprehension, diverging from the signals of confusion or uncertainty. Hence, the time taken to initiate the test is a more telling sign of a potential misunderstanding of the instructions provided during SFST.
