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 ...
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.
Basic concepts are always formed on the basis of consensus, the other derived from them by definition, to avoid to Circular definition. To improve the accuracy of research and communication (reducing the internal vagueness of connotation), tools such as classification schemes are used, such as the taxonomy of organisms by Carl von Linné .

In visual perception, an optical illusion (also called a visual illusion [2]) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality.
