Task 3 SART (Sustained Attention to Response Task) Lecture Hall

In this task users will be placed in a lecture hall. In front of them there will be a lecturer explaining a topic and other students. In their table, they can see a book, and, in that book, we present them digits from 1 to 9. Their task is to press the button of the controller when all the digits are shown except for digit 3.

To understand users ability to focus on sustained attention task and their response strategy, response inhibition, or motor impulsivity.

Groups of participants:
-People with ADHD/ADHD traits
-People who stutter

Task Details:
For this tasks, there will be sounds from lecturer who will explain a topic, sounds from students like coughing, sneezing, talking, writing, paper flipping. At a certain point a paper plane will fly and land in ground (with a sound). In total there will be 225 digits shown. Each digit will be presented 25 times (225/9) randomly after a delay of 1.15 seconds each. Each digit is shown for 1.15 seconds.

Q1: Pressing the button for the wrong number affected my next responses.
Q2: The lecturer and other students were distracting me during this task.
Q3: I think I did very well in completing this task.
Q4: I think I didn’t do very well in completing this task.
Q5: The task was interesting and was similar to a scenario that can happen in our day-to-day life.
Q6: I felt present and involved in VR.
