Do you want to help us gain insights into what drives intrusive thoughts and memories? In this study we will examine people's intrusions of negative film clips and video games.
WHAT DO I HAVE TO DO?
The study involves three in-person sessions (30 minutes to 1 hour each) on 3 consecutive days (24-hours apart) in a lab at the Roeterseiland (REC-L).
In the first experimental session you will fill out several questionnaires and become familiarized with two simple but very popular games, Tetris and Candy Crush. Thereafter, you will watch sets of videos (the videos contain quite graphic or scary scenes, which may be distressing to you!). After each set, we will ask you several questions. Then, in the second sessions you will perform a a computer task and play Tetris and Candy Crush. Finally, during the third and final session you will perform another computer task in the lab.
In between the lab sessions you will be required to record any intrusions (e.g., spontaneous flashbacks/ memories) concerning the films that you watched or video games that you played.
The whole procedure will take approximately 3 hours and you will be compensated with 3 RCs or 30 euros depending on your preference.
AM I ELIGIBLE?
In order to take part, you need to be between 18 and 65 years of age and have a good understanding of English. You are NOT eligible to take part if:
- You are currently receiving, or have recently received, treatment for post-traumatic stress symptoms, including medication, psychological therapy or counselling
- You have a neurological illness (e.g., epilepsy)
- You have significant visual or hearing impairments, or colour blindness
- You are not in the possession of a smartphone
- You have blood phobia
- You have recently (within the past 3 weeks) played Tetris or Candy Crush or were a habitual player in the past

Online onderzoek | 15.00 Euro / 3.00 Communication Science Research Credit
In this study, we ask you to install TikTok on your phone for 16 days. Every morning, you will complete a very short survey about your experiences via a research app (Avicenna). In addition, we ask you to upload screenshots of your TikTok screen time metrics, which can be found in the TikTok app.
PROCEDURE
Day 1 (today):
By clicking *participate* below, you will be redirected to a form including detailed information about the study procedure and an informed consent question. If you decide to participate, you are asked to install the research app Avicenna on your phone. Via the app, you will complete a short 5-minute entry survey. At the end of the entry survey, you are instructed to install TikTok with specific settings (e.g., to protect your privacy). We then ask you to use TikTok for at least 30 minutes. During the rest of the study period, you are free to use TikTok whenever you want.
Day 2 – 16:
Every morning at 8:00, you will receive a short 2-minute survey via the Avicenna app, to be completed preferably in the morning. The daily survey includes questions about your experiences with TikTok the day before, and we ask you to upload screenshots from your TikTok use metrics (time spent & number of times opened).
Day 16:
After the daily survey on day 16, you will receive a 5-minute exit survey in which we ask for your general reflections on the past two weeks. After completing the exit survey, you will receive your study reward and we will provide instructions on how to delete your TikTok account.
REWARD
For participating in this study, you will receive 3 Communication Science Research Credits or 15 Euros. In order to receive payment or course credit, we expect you to follow the instructions and take part in all parts of the study. This includes the entry survey, the short mobile surveys once a day, and the exit survey. Participating in this study will take about 80 minutes in total (including the 30 minutes of TikTok use).
ELIGIBILITY CRITERIA
- You are 18 years or older
- You are currently not using TikTok or Douyin, and have not done so in the past 6 months.
- You already want to test TikTok anyway. This means you should not install TikTok solely for the purpose of this study.
The study will be conducted in English.
