词条 Crowding
释义

  1. References

{{For|the medical sociology concept|Overcrowding}}Crowding is a perceptual phenomenon where the recognition of objects (or graphemes) presented away from the fovea is impaired by the presence of other neighbouring objects (sometimes called "flankers").[1] It has been suggested that crowding occurs due to mandatory integration of the crowded objects by a texture-processing neural mechanism.[2]

Crowding deficits have been specifically found in neuropsychiatric disorders such as schizophrenia and autism and may have profound clinical implications in these disorders.[3]

If objects remain within your visual field over time, then priming (psychology) begins to occur and the objects become less cluttered.[4]
