Visual filling-in
How is the blind spot filled in? The natural blind spot is a retinal region devoid of photoreceptors, where the head of the optic nerve joins the retina (Figure 1A). Close your left eye and extend your right arm straight in front of you. Spread your fingers wide, palm down, and gaze at your thumbnail. Now wiggle your little finger. It will fall on your blind spot and you will be unable to see i...
متن کاملFilling-in visual motion with sounds.
Information about the motion of objects can be extracted by multiple sensory modalities, and, as a consequence, object motion perception typically involves the integration of multi-sensory information. Often, in naturalistic settings, the flow of such information can be rather discontinuous (e.g. a cat racing through the furniture in a cluttered room is partly seen and partly heard). This study...
متن کاملPreattentive filling-in of visual surfaces in parietal extinction.
Unilateral brain damage frequently produces "extinction," in which patients can detect brief single visual stimuli on either side but are unaware of a contralesional stimulus if presented concurrently with an ipsilesional stimulus. Explanations for extinction have invoked deficits in initial processes that operate before the focusing of visual attention or in later attentive stages of vision. P...
متن کاملVisual field anisotropy revealed by perceptual filling-in
Four experiments were performed to investigate how the time required for perceptual filling-in varies with the position of the target in the visual field. Conventional studies have revealed that filling-in is facilitated by a target with greater eccentricity, while no systematic studies have examined the effect of polar angle. Experiment 1 examined the effect of polar angle when the target and ...
متن کاملFilling gaps in visual motion for target capture
A remarkable challenge our brain must face constantly when interacting with the environment is represented by ambiguous and, at times, even missing sensory information. This is particularly compelling for visual information, being the main sensory system we rely upon to gather cues about the external world. It is not uncommon, for example, that objects catching our attention may disappear tempo...
