Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Researchers will compare DVN to static visual noise (SVN), which is a still image of black and white squares that has been used as a control condition for DVN in prior literature.
Participants will:
1. Visit the laboratory once to complete the baseline data collection
2. Watch the DVN or SVN every day for seven days (including the day of the laboratory visit)
3. Complete daily follow-ups for six days following the day of the laboratory visit
4. Complete a final follow-up on the seventh day following the laboratory visit

Dynamic Visual Noise (DVN)
Dynamic Visual Noise (DVN)
DVN is a brief visual array of patterns of flickering black and white dots. In alignment with prior literature, the DVN array will consist of an 80 x 80 grid of 4 x 4 black and white pixel squares that will change at a rate of 640 frames per second. The DVN will be 30 seconds in duration, though participants will be able to keep watching for as long as desired by restarting the video of the array.
Static Visual Noise (SVN)
Static Visual Noise (SVN)
SVN is similar to DVN, but refers to a static (or still) image of an array of black and white squares. The SVN will consist of an 80 x 80 grid of 4 x 4 black and white pixel squares. SVN has been used in previous working memory-loading studies as a control for DVN. Similar to the DVN, participants in the control group will view the SVN for at least 30 seconds (but they will be able to keep viewing it for as long as desired).
