Definition of inducer and concurrent

In synesthesia, the inducer is the stimulus that triggers the synesthetic experience, and the concurrent is the synesthetic experience itself.

 

Examples of inducers and concurrents:

 

Inducer: the sound of a violin.

Concurrent: seeing a yellow line.

(In auditory-visual synesthesia.)

 

Inducer: reading the word “telephone”.

Concurrent: experiencing a taste of melon.

(In lexical-gustatory synesthesia.)
