| ESP | Extra-Sensory Perception |
| time perception | The ability to estimate periods of time lapsed or duration of time. (12 Dec 1998) |
|---|---|
| extrasensory perception | Perception by means other than through the ordinary senses; e.g., telepathy, clairvoyance, precognition. (05 Mar 2000) |
| form perception | The sensory discrimination of a pattern shape or outline. (12 Dec 1998) |
| loudness perception | The perceived attribute of a sound which corresponds to the physical attribute of intensity. (12 Dec 1998) |
| accessory visual apparatus | The eyelids, with lashes and eyebrows, lacrimal apparatus, conjunctival sac, and extrinsic muscles of the eyeball. Synonym: organa oculi accessoria, accessory organs, accessory visual apparatus, adnexa oculi, appendages of eye. (05 Mar 2000) |
| Bender Visual Motor Gestalt test | <psychology> A psychological test used by neurologists and clinical psychologists to measure a person's ability to visually copy a set of geometric designs. It consists of nine geometric designs on cards. The subject is asked to redraw them from memory after each one is presented individually. It is useful for measuring visuospatial and visuomotor coordination to detect brain damage. Synonym: Bender Visual Motor Gestalt test. (14 Aug 2000) |
| Broca's visual plane | A plane drawn through the visual axes of each eye. (05 Mar 2000) |
| receptor, visual | The layer of rods and cones, the visual cells, of the retina. (12 Dec 1998) |
| pattern recognition, visual | Visually perceived characters, shapes, displays, or designs. (12 Dec 1998) |
| visual | Pertaining to vision or sight. Origin: L. Visualis, from videre = to see (18 Nov 1997) |
| visual acuity | <microscopy> The ability to detect fine details or small distances with the eye. Visual acuity can vary substantially depending on the definition used and method of measurement chosen. Under favourable conditions, the resolution of the human eye or ability to distinguish the twoness of adjoining lines, is about I minute of arc while the threshold delectability, or the detection of misaligned steps in a line (which is also a form of visual acuity), can be as low as a fraction of a second of arc. (05 Aug 1998) |
| visual agnosia | The inability to recognise objects by sight; usually caused by bilateral parieto-occipital lesions. Synonym: optic agnosia. (05 Mar 2000) |
| visual angle | The angle formed at the retina by the meeting of lines drawn from the periphery of the object seen. (05 Mar 2000) |
| visual aphasia | <neurology> Loss of the ability to understand printed words or sentences (27 Sep 1997) |
| visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
