Associator Synesthesia

Associator synesthesia is a form of synesthesia in which a stimulus consistently produces an internal sensory or conceptual association rather than an externally perceived sensation. For example, hearing music may automatically evoke the vivid mental impression of a specific color, or seeing a letter may trigger a stable color association in the mind’s eye, even though nothing is literally seen in external space. In contrast to projector synesthesia, the synesthetic experience remains primarily cognitive or imaginative — strong, automatic, and consistent, but internally experienced.
