A usability test session is scheduled for a participant who requires a screen reader due to a visual impairment. The facilitator has prepared the test environment, but the screen reader software is not functioning properly. The participant has arrived. What should the facilitator do?

Cancel the session and do not reschedule, as the technical issue is too complex.

Proceed with the session without the screen reader, as the participant can still interact with the product.

Attempt to fix the screen reader quickly, and if it cannot be fixed, reschedule the session.

Ask the participant to use their own assistive technology device.

What should the facilitator do if a participant in a pilot session struggles to understand a task?

Immediately rephrase the task to help the participant complete it

Note the difficulty and continue observing, as this indicates a potential problem with the task wording

End the pilot session immediately because the task is flawed

Ask the participant to skip the task and move on to the next one

A usability test session is underway. The facilitator is observing the participant and taking notes. What is the most important thing for the facilitator to record?

The exact time the participant spends on each task.

The participant's facial expressions and body language only.

The facilitator's own opinions about the participant's performance.

The participant's actions, verbal comments, and any notable behaviors or difficulties.

When a participant arrives for a usability test session, what is the first thing the facilitator should do?

Give the participant the first task to begin

Greet the participant and make them feel comfortable

Ask the participant to sign the consent form without explanation

Start the recording equipment immediately

During a usability test, a participant becomes frustrated with a task and says, 'This is impossible!' The facilitator needs to respond in a way that does not influence the participant's behavior. What is the most appropriate response?

Say, 'You are doing fine. Most people find this task difficult.'

Say, 'Let me show you how to do it so you can continue.'

Say, 'I understand this task may be challenging. Please continue and tell me what you are thinking.'

Say, 'Would you like to skip this task and move on?'
