In this video Dr. Jamie Ward examines the co-occurrence of multiple types of synesthesias within synesthetes. These co-occurring types tend to occur in typed groups, but the number of types of synesthesia makes it hard to quantify. He also discusses...
Can one acquire synesthesia later in life? In his answer, Dr. Ward points out a few instances in which unused sensory pathways can cause the development of synesthesia-like symptoms after the loss of a sensory system (Like the onset of blindness)....
The adjacency principle, the idea that pairings in synesthetes are a result of the neural areas in which the information is processed being adjacent to one another, is one of the leading theories about the cause of synesthesia.
This video looks into whether or not there is a genetic basis for synesthesia. Dr. Ward bases this discussion on evidence of synesthesia running in families, chromosomal evidence, and developmental evidence.
