Brief Summary

The researchers hypothesize that there is a correlation between Vestibulo-ocular reflex (VOR) performance and innate athletic skill level. A similar study was conducted in female, young adult gymnasts where a correlation was shown between VOR performance and gymnastic skill level. However, the results from this study did not suggest that VOR differences develop as a result of practice; rather that the differences in VOR may simply allow some individuals to become better performers. In this study the researchers would like to extend the population to adults both with and without a background in gymnastics to determine the natural relationship between VOR and innate athletic potential.

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Approximately 12 adults (6 ex-gymnastics, and 6 age matched, non-gymnast counterparts), ages 18-30 will be obtained via a sample of convenience from the University community. Subjects will be asked to wear a measurement system (Eyelink II, SR Research) that tracks head and eye movements as they perform as set of eye and head movements to measure saccadic eye movements, VOR and VOR suppression. Periodic calibrations will be performed throughout the experiment to test the continued reliability of the data.

You may qualify if:

• Normal, adults will be recruited from the University community via a sample of convenience.

You may not qualify if:

• Children under the age of 18.
