Stroboscopic Training Improves Performance, Says Duke U. Study
Stroboscopic training, performing a physical activity while using
eyewear that simulates a strobe-like experience, reportedly increases visual short-term memory retention, and the effects last for 24
hours. Participants in a Duke University study engaged in physical
activities, such as throwing a baseball, while using either specialized
eyewear that limits vision to only brief snapshots or while using
eyewear with clear lenses that provides uninterrupted vision.
Participants from the Duke community, including varsity athletes,
completed a computer-based visual memory test before and after the
physical activities. The study found that participants who trained with
the strobe eyewear gained a boost in visual memory abilities. Participants completed a memory test that required them to note the
identity of eight letters of the alphabet that were briefly displayed on
a computer screen. After a variable delay, participants were asked to
recall one of the eight letters. On easy-level trials, the recall prompt
came immediately after the letters disappeared, but on more difficult
trials, the prompt came as late as 2.5 seconds following the display.
Because participants did not know which letter they would be asked to
recall, they had to retain all of the items in memory. Read more about the study.
