Manipulation of extraocular muscle afference has no effect on higher order perceptual judgments by Niechwiej-Szwedo, E., González, E.G., Bahl, B., Verrier, M.C., Wong, A.M., Steinbach, M.J.

“…Observers perceive targets as farther while performing the Jendrassik Maneuver (JM) suggesting that eye position is registered as more divergent. We examined…”

Localization in the frontal plane is not susceptible to manipulation of afferent feedback via the Jendrassik Maneuver by Niechwiej-Szwedo, E., González, E.G., Verrier, M.C., Wong, A.M., Steinbach, M.J.

“…We have previously shown that registered vergence eye position is altered while participants perform the Jendrassik Maneuver (JM). We proposed that the altered…”

Accuracy of estimating time to collision using only monocular information in unilaterally enucleated observers and monocularly viewing normal controls by Steeves, J.K.E, Gray, R, Steinbach, M.J, Regan, D

“…Since individuals who have lost an eye in early life rely on monocular information, one asked if they would better estimate the time to collision (TTC) with an…”

Registered eye position : short- and long-term effects of botulinum toxin injected into eye muscle by DENGIS, C. A, STEINBACH, M. J, KRAFT, S. P

“…Botulinum toxin is sometimes injected into human eye muscles as an alternative to surgery in the correction of strabismus. Within minutes of botulinum…”

Vertical eye position control in darkness: Orbital position and body orientation interact to modulate drift velocity by GOLTZ, H. C, IRVING, E. L, STEINBACH, M. J, EIZENMAN, M

Alignment ability of strabismic and eye enucleated subjects on the horizontal and oblique meridians by Reed, M J, Steinbach, M J, Ono, H, Kraft, S, Gallie, B

The Cyclops effect in adults: Sighting without visual feedback by Dengis, Carol A., Simpson, Trefford L., Steinbach, Martin J., Ono, Hiroshi

“…When asked to look through a tube, younger children place it at the bridge of the nose, and not over one eye: the Cyclops effect. This is a natural response to…”
