title: A comparison of static and dynamic stereoacuity.
abstract: It is usually assumed by the clinician that a person's total stereoscopic ability can be measured by routine stereoacuity tests. Yet, there is considerable evidence that the brain processes static and moving images via separate channels. In an attempt to determine the validity of the clinician's assumption, we compared results of the Titmus and TNO stereoacuity test with that of a dynamic stereoacuity test of our design. The data obtained from 146 subjects showed no correlation between static and dynamic responses. It seems improbable, therefore, that stereoscopic ability in the real world can be predicted from static clinical stereoacuity tests. The implication of dynamic stereopsis in sports vision and athletic performance is discussed.
