Frequently Asked Questions
1. How do I know if I qualify for the study?
Some of the important criteria for the study include:
– Being at least 18 years old
– Having normal or corrected to normal vision (glasses and contacts are fine)
– Having good hearing
– Being able to make verbal responses and manual responses, such as pressing keys on a computer keyboard
– Having a documented history of concussion(s) or mild traumatic brain injury that is documented (i.e., a doctor or other professional diagnosed the condition)
2. What do you mean a “documented history of concussion or mild traumatic brain injury?”
A documented history of concussion or mild traumatic brain injury means that you had a blow or jolt to the head severe enough that you saw a doctor or another professional as a result. Following the injury, you may have experienced any of the following symptoms:
Loss of consciousness for a few seconds to a few minutes
No loss of consciousness, but a state of being dazed, confused or disoriented
Nausea or vomiting
Fatigue or drowsiness
Sleeping more than usual
Dizziness or loss of balance
Sensitivity to light or sound
Memory or concentration problems
Mood changes or mood swings
Feeling depressed or anxious
If you experienced a severe traumatic brain injury, which resulted in a prolonged hospital stay or intensive rehabilitation, you may not be eligible for the study. But please contact us to check.
3. Do I need to be fluent in both English and Spanish to participate?
One requirement for the study is that participants must be highly proficient in English, meaning that they speak, understand, and read English fluently. In addition to English proficiency, we want participants who have some degree of Spanish language proficiency – ranging from minimal Spanish experience to fluent Spanish speakers. If you have taken a few courses in Spanish, know basic Spanish vocabulary, and some reading ability, we would consider this sufficient Spanish language experience. On the other end of the range, we are also looking for people who are highly fluent in Spanish or whose native language is Spanish. Of course, we also accept people whose Spanish proficiency falls anywhere in between basic and fluent. If you do not speak Spanish at all, please send us an email and we can let you know if you could still be eligible.
4. How much time does the experiment take and what will I be doing?
The study consists of a questionnaire that can be completed at home and two in-person testing sessions, each lasting approximately 2 hours. During the testing sessions, you will complete several computerized tasks that test your memory, attention, reasoning, and language abilities. Each computerized task takes about 10 to 15 minutes to complete. You will also complete a formal assessment of your reasoning ability, which takes about 30-40 minute to complete. You can also take brief breaks in between tasks. In one session, you will complete computerized tasks during which your eye movements will be recorded.
5. Where does the study take place?
The in-person testing takes place over two sessions. The first session will take place in Coor Hall on ASU’s Tempe campus. If this is not convenient for you, we may be able to arrange to test you in an alternative location. The second session takes place in a Psychology building on ASU’s Tempe campus. Due to equipment restrictions, the second session must be conducted at a specific location.
6. What do I get for participating in the study?
For participating, you will be given a compensation of $10 per hour. Additionally, after your testing sessions, you will be provided with a report about your individual memory, reasoning, and language skills. This report may be informative and helpful in that it will help you understand your cognitive strengths and weaknesses.
