Question

which semiotic concept requires a viewer to learn a connection between a visual representation and its meaning? sign index symbol icon

Explanation:

In semiotics, a symbol is a sign where the connection between the visual representation and its meaning is arbitrary and learned. For example, the word "dog" (visual representation - the written word or the sound when spoken) has a meaning (a four - legged domestic animal) that is learned. It is not based on a direct physical resemblance (like an icon, which has a direct visual link to its meaning, e.g., a picture of a dog) or a causal connection (like an index, e.g., smoke as an index of fire). A sign is a more general term in semiotics that encompasses symbols, icons, and indices.
