We have demonstrated that short-term vertical position-specific phoria adaptation contributes to nonconjugate adaptation of vertical pursuits, but not to nonconjugate adaptation of vertical saccades. Binocular adaptation to multiple stationary vertical disparities resulted in both nonconjugate pursuits and phoria aftereffects but had little effect on the early step component of vertical saccades. Similarly, binocular nonconjugate adaptation of vertical pursuits produced both nonconjugate pursuits and fixation phoria aftereffects. Position-specific adaptation of nonconjugate pursuit was demonstrated by adapting to disparate motion in the upper field which resulted in nonconjugate pursuit aftereffects that were greater in the upper than the lower hemifield. These nonconjugate pursuits were accompanied by position-specific phoria aftereffects, indicating that common mechanisms underlie adaptation of vertical phoria and nonconjugate pursuits.
我们已经证明，短期垂直位置特异性隐斜视适应有助于垂直跟踪的非共轭适应，但对垂直扫视的非共轭适应没有作用。双眼对多个固定垂直视差的适应导致了非共轭跟踪和隐斜视后效，但对垂直扫视的早期阶跃成分影响很小。同样，垂直跟踪的双眼非共轭适应产生了非共轭跟踪和注视性隐斜视后效。通过适应上半视野的不同运动来证明非共轭跟踪的位置特异性适应，这导致了上半视野比下半视野更大的非共轭跟踪后效。这些非共轭跟踪伴随着位置特异性隐斜视后效，表明垂直隐斜视和非共轭跟踪的适应有共同的机制。
