Examples of visually ambiguous patterns. From top to bottom: Necker cube, Schroeder stairs and a figure that can be interpreted as black or white arrows. Multistable perception (or bistable perception) is a perceptual phenomenon in which an observer experiences an unpredictable sequence of spontaneous subjective changes.
Ambiguous images or reversible figures are visual forms that create ambiguity by exploiting graphical similarities and other properties of visual system interpretation between two or more distinct image forms. These are famous for inducing the phenomenon of multistable perception. Multistable perception is the occurrence of an image being able ...
Visual perception is the ability to detect light and use it to form an image of the surrounding environment. [1] Photodetection without image formation is classified as light sensing. In most vertebrates, visual perception can be enabled by photopic vision (daytime vision) or scotopic vision (night vision
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The timing of perception of a visual event, at points along the visual circuit, have been measured. A sudden alteration of light at a spot in the environment first alters photoreceptor cells in the retina, which send a signal to the retina bipolar cell layer which, in turn, can activate a retinal ganglion neuron cell.
Lexical ambiguity is contrasted with semantic ambiguity. [ citation needed ] The former represents a choice between a finite number of known and meaningful context -dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning.
Oxford Dictionary of Biology (often abbreviated to ODB) is a multiple editions dictionary published by the English Oxford University Press. With more than 5,500 entries, [ 1 ] [ 2 ] it contains comprehensive information in English on topics relating to biology , biophysics , and biochemistry . [ 3 ]
Agnosias are sensory modality specific, usually classified as visual, auditory, or tactile. [2] [3] Associative visual agnosia refers to a subtype of visual agnosia, which was labeled by Lissauer (1890), as an inability to connect the visual percept (mental representation of something being perceived through the senses) with its related semantic information stored in memory, such as, its name ...
