Synesthesia is a systematic and involuntary sensory experience induced by an unrelated stimulus. People with synesthesia, who are referred to as synesthetes,  have a neurological condition in which information stimulates many different senses. Some common forms of synesthesia include seeing a letter or number that induces a color, hearing sounds that induce color sensations, and more. It can be divided into "weak" and "strong" subcategories, in which strong is the aforementioned definition and weak is seen in everyones sense of cross-sensory correspondences.

There are many theories as to why this condition occurs such as retaining low-level, cross-sensory connections (that would typically sever during the later stages of infancy), or the lack of inhibiting processes that eliminate certain types of signals from flowing into or across sensory brain areas. It is interesting to note that "specific associations experienced by synesthetes may be based on their experience" (Rosenblum 284); An example of this association by experience can be found in the colorful letter and number magnets for the refrigerator that children use. A child sees that the letter "D" on the refrigerator is the color red - if the child is a synesthete, then as they grow older they will always see the letter D as red! This may differ from someone else who had a different set of fridge magnets, or no magnets at all, that instead see the color "D" as light blue.

  1. Hi Deonna Powell!
    I enjoyed reading your discussion post. You did a good job explaining synesthesia and providing examples. My understanding of synesthesia is sound, shape, color, taste, or smell. An example is hearing music and seeing colors in your mind. It is using colors to visualize. I like how you provided a video to explain synesthesia. The video was enjoyable to watch. The book provides good information on synesthesia. Overall good job!

  2. Great discussion post! I found this information on synesthesia very interesting. I would be interested in talking to someone with this condition to get their perspective on life.

  3. Hi Deonna! Very interesting post! I wonder why they experience the world this way as in what is different about their genetic makeup vs someone who does not have this condition.
