According to perceptual symbol systems theory, bottom-up patterns of activation within sensory-motor areas become associated during perception, and thus become perceptually-based symbols. Barsalou suggests that attentional mechanisms then bind these diverse perceptual components into stable networks of associations, termed simulators, which are ...
A sign can be a word, sound, a touch or visual image. Saussure divides a sign into two components: the signifier, which is the sound, image, or word, and the signified, which is the concept or meaning the signifier represents. For Saussure, the relation between the signifier and the signified is arbitrary and conventional.
Tangible symbols are a type of augmentative and alternative communication (AAC) that uses objects or pictures that share a perceptual relationship with the items they represent as symbols. A tangible symbol's relation to the item it represents is perceptually obvious and concrete – the visual or tactile properties of the symbol resemble the ...
Semiotics is the theory of symbols and falls in three parts; logical syntax, the theory of the mutual relations of symbols, logical semantics, the theory of the relations between the symbol and what the symbol stands for, and; logical pragmatics, the relations between symbols, their meanings and the users of the symbols."

In semiotics, a sign is anything that communicates a meaning that is not the sign itself to the interpreter of the sign. The meaning can be intentional, as when a word is uttered with a specific meaning, or unintentional, as when a symptom is taken as a sign of a particular medical condition.
Aldous Huxley is regarded as one of the most prominent explorers of visual communication and sight-related theories. [12] Becoming near-blind in his teen years as the result of an illness influenced his approach, and his work includes important novels on the dehumanizing aspects of scientific progress, most famously Brave New World and The Art of Seeing.
A FBI document obtained by Wikileaks details the symbols and logos used by pedophiles to identify sexual preferences. According to the document members of pedophilic organizations use of ...
Example of a multi-dimensional perceptual map. Traditional perceptual maps are built with two visual dimensions (X- and Y-axis). Multidimensional perceptual maps are built with more dimensions visualised as profile charts in small map regions, and then items are mapped to the regions by their similarity to the vectors that represent the region.
