The ability of infants to discriminate zero-disparity stimuli from both reverse contrast (rivalrous) and disparate (stereoscopic) stimuli was investigated in a two-alternative, forced-choice, preferential-looking paradigm. Few infants under 4 months of age demonstrated discrimination for any stimulus pairing. Of the infants tested at 4 months of age, approximately 70% preferred zero-disparity stimuli to reverse contrast stimuli, and 82% preferred stereoscopic stimuli to zero-disparity stimuli. Nearly 100% of 5- and 6-month-old infants exhibited these preferences. These findings suggest that sensory fusion is not present at birth but develops rapidly over the first 6 months of life. The time course for the development of sensory fusion was similar to the time course for the development of stereopsis in nine infants tested longitudinally.
在一种二选一、强制选择、优先注视的范式中，研究了婴儿区分来自反向对比（竞争）和视差（立体视觉）刺激的零视差刺激的能力。4个月以下的婴儿很少表现出对任何刺激配对的辨别能力。在4个月大时接受测试的婴儿中，约70%更喜欢零视差刺激而非反向对比刺激，82%更喜欢立体视觉刺激而非零视差刺激。5至6个月大的婴儿中近100%表现出这些偏好。这些发现表明，感觉融合并非出生时就存在，而是在生命的头6个月迅速发展。在对9名婴儿进行纵向测试时，感觉融合的发展时间进程与立体视觉的发展时间进程相似。
