Rapid eye movements include saccades and quick phases of nystagmus and may have components around all three axes of ocular rotation: horizontal, vertical, and torsional. In this study, we recorded horizontal, vertical, and torsional eye movements in normal subjects with their heads upright and stationary. We asked how the eyes are brought back to Listing's plane after they are displaced from it...

In addition to vertical time shifts commonly observed in time-lapse seismic images, horizontal displacements are apparent as well. These apparent horizontal displacements may be small relatively to seismic wavelengths, perhaps only 5 m at depths of 5 km, but they consistently suggest an outward lateral expansion of images away from a compacting reservoir. It is well known that apparent vertical...

Do Chinese speakers think about time vertically because they use vertical spatial metaphors to express time? Inconsistent findings have been reported even when the same paradigms were used. The present study examined participants’ performance on a temporal judgment task while holding language constant but varying their lifetime and immediate reading experience of horizontal and vertical texts. ...
