| 영문 | binocular vision | 한글 | 두눈보기, 양안시 |
|---|---|---|---|
| 설명 | 좌우 양쪽의 눈으로 상을 보는 경우이며, 단안시에 대응하는 용어이다. 양쪽 눈을 이용해서 한 물체를 볼 경우엔 입체적으로 보인다. 양쪽 안구의 협조적인 작용에 의하여 양안으로 동일한 점을 주시하여 하나의 물체로 보게 된다. 단안시에 비하여 맹점을 보완하고 시력을 증대하며, 더욱이 공간의 퍼짐을 인지하거나 입체시를 보다 완전하게 할 수 있다. 포유류에서도 좌우 양안의 시축 각도의 벌어짐은 여러 가지로서, 사자는 10°, 개는 30~50°, 노루는 100°, 토끼는 170°이다. 정면의 물체는 양쪽 눈으로 볼 수 있으나 좌우 방향에 있는 물체는 양쪽 눈을 동시에 움직여 한족 눈으로 보는 것과 같은 경우가 많다. 육식동물은 양안시형이 많고, 설치류나 유제류와 같은 초식동물은 단안시형이 많다. 조류에서도 올빼미 등은 양안시형이고, 닭 등은 단안시형이다. |

| visual-spatial agnosia | The inability to localise objects or to appreciate distance, motion, and spatial relationships; caused by lesion in the occipital lobe. Compare: simultanagnosia. (05 Mar 2000) |
|---|---|
| spatial | Relating to space or a space. (05 Mar 2000) |
| spatial acuity | The detection of the shape of a test object; e.g., perceiving polygons of the same size but with different numbers of sides. (05 Mar 2000) |
| spatial behaviour | Reactions of an individual or groups of individuals with relation to the immediate surrounding area including the animate or inanimate objects within that area. (12 Dec 1998) |
| spatial filter | <radiobiology> Device consisting of a lens pair and a pinhole aperture stop. Intensity fluctuations over the spatial extent of a laser beam are removed by passing the focused beam through the aperture stop. The pinhole must be placed in a vacuum to prevent air breakdown by the focused beam. These filters are used to counter the effects caused by self-focusing. (09 Oct 1997) |
| spatial formula | A chemical formula in which the arrangement of the atoms or atomic groupings in space are indicated. Synonym: spatial formula. (05 Mar 2000) |
| spatial localization | The reference of a visual sensation to a definite locality in space. (05 Mar 2000) |
| spatial sensing | Mechanism of sensing a gradient in which the signal is compared at different points on the cell surface and cell movement directed accordingly. Translocation of all or part of the cell is not required. See: temporal gradient sensing, pseudospatial gradient sensing. (18 Nov 1997) |
| spatial vector | A cardiac vector represented in more than one plane simultaneously; two-or three-dimensional orientation of a vector. (05 Mar 2000) |
| spatial vectorcardiography | Three-dimensional vectorcardiography in which vector loops are inscribed in frontal, sagittal, and horizontal planes. (05 Mar 2000) |
| achromatic vision | A severe congenital deficiency in colour perception, often associated with nystagmus and reduced visual acuity. Synonym: achromatic vision, monochromasia, monochromasy, monochromatism. Origin: G. A-priv. + chroma, colour, + opsis, vision (05 Mar 2000) |
| binocular vision | Vision with a single image, by both eyes simultaneously. (05 Mar 2000) |
| blue vision | A condition in which all objects appear blue; may temporarily follow cataract extraction. Synonym: blue vision, cyanopia. Origin: cyano-+ G. Opsis, vision (05 Mar 2000) |
| red vision | An abnormality of vision in which all objects appear to be tinged with red. Synonym: red vision. Origin: erythro-+ G. Ops, eye (05 Mar 2000) |
| vision | 1. <ophthalmology> The act or faculty of seeing, sight. 2. <psychiatry> An apparition, a subjective sensation of vision not elicited by actual visual stimuli. 3. Visual acuity, symbol V. Origin: L. Visio (18 Nov 1997) |
