Our visual systems combine the two, slightly different, retinal images to arrive at a stable and continuous percept of a given scene around us. While a large proportion of any scene is binocular, there are a host of regions that can only be seen by one eye. Rather than being ignored, these monocular regions are integrated with the surrounding binocular regions and their content is consciously accessible to us. However, our perception of the information contained in monocular regions seems to be slightly different from that of information that is seen by both eyes (binocularly). Ono et al (2003), for example, report that monocular regions appear slightly displaced and compressed, as if to 'fit' into the surrounding binocular space. Here we discuss two experiments that investigate our perception of monocular regions further. We used two relative numerosity tasks to study whether monocular regions lead to a percept that is comparable to that of binocular regions, and we explored how the two types of regions are integrated to form a seemingly stable and continuous percept.
