Previous studies revealed that there are idiosyncratic preferences to perceive certain motion directions in front during motion transparency depth rivalry (Mamassian & Wallace, 2010; Schütz, 2014). Meanwhile, other studies reported idiosyncratic preferences in binocular rivalry during the onset stage (Carter & Cavanagh, 2007; Stanley, Carter, & Forte, 2011). Here we investigated the relationship of idiosyncratic preferences in transparent motion and binocular rivalry. We presented two dot clouds that were moving in opposite directions. In the transparent motion condition, both dot clouds were presented to both eyes and participants had to report the dot cloud they perceived in front. In the binocular rivalry condition, the dot clouds were presented to different eyes and participants had to report the dominant dot cloud. There were strong idiosyncratic directional preferences in transparent motion and rather weak directional preferences in binocular rivalry. In general, binocular rivalry was dominated by biases in contrast polarity, whereas transparent motion was dominated by biases in motion direction. A circular correlation analysis showed no correlation between directional preferences in transparent motion and binocular rivalry. These findings show that idiosyncratic preferences in a visual feature can be dissociated at different stages of processing.
先前的研究表明，在运动透明深度竞争（Mamassian & Wallace，2010；Schütz，2014）中，人们对感知前方某些运动方向存在特殊偏好。同时，其他研究报告称在双眼竞争的起始阶段也存在特殊偏好（Carter & Cavanagh，2007；Stanley、Carter 和 Forte，2011）。在这里，我们研究了透明运动和双眼竞争中特殊偏好之间的关系。我们呈现了两个以相反方向移动的点云。在透明运动条件下，两个点云都呈现给两只眼睛，参与者必须报告他们看到的前面的点云。在双眼竞争条件下，点云呈现给不同的眼睛，参与者必须报告主导的点云。在透明运动中有强烈的特殊方向偏好，而在双眼竞争中则有较弱的方向偏好。总的来说，双眼竞争主要受对比极性偏差的影响，而透明运动主要受运动方向偏差的影响。圆相关分析显示，透明运动和双眼竞争中的方向偏好之间没有相关性。这些发现表明，在不同的处理阶段，可以分离出对视觉特征的特殊偏好。
