Immediate Effect of Subliminal Priming With Subliminal Reward Stimuli on Standing Balance in Healthy Young Adults

Study Overview
=================
Brief Summary
-----------------
The purpose of the study was to examine the immediate effect of subliminal priming with subliminal reward stimuli on standing balance in healthy young adults. The study also compared the outcomes with the immediate effects of subliminal priming with supraliminal reward stimuli.

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Subliminal priming with subliminal reward stimuli<br>This intervention consisted of five presentations [three cycles of mosaic (displayed for 117 ms each), physical exertion words as subliminal priming (displayed for 17 ms), and positive words as subliminal reward (displayed for 17 ms)]. These were set to 1 package. 1 package is 24 times per 5 seconds presented in the animation (Animation of Skateboarding) for approximately 2 min. | Other: Subliminal priming with subliminal reward stimuli<br>* Positive words as subliminal reward (displayed for 17 ms).<br>|
| Experimental: Subliminal priming with supraliminal reward stimuli<br>This intervention consisted of four presentations [two cycles of mosaic (displayed for 117 ms each), physical exertion words as subliminal prime (displayed for 17 ms), and positive words as supraliminal reward (displayed for 150 ms)]. These were set to 1 package. 1 package is 24 times per 5 seconds presented in the animation (Animation of Skateboarding) for approximately 2 min. | Other: Subliminal priming with supraliminal reward stimuli<br>* Positive words as supraliminal reward (displayed for 150 ms).<br>|
