Imagine tasting what you hear, seeing colors when you hear numbers, or being able to make quick calculations because you see numbers around you. Such situations called synesthesia, a rare condition marked by intermingling or blending of the senses, are the subject of this video originally produced as part of the BBC Horizon Science documentary series. The video features Dorothy Latham who sees colors with numbers; James Wannerton who has an unusual form of the condition by associating sounds with taste; and John Fullwood, who although blind, is able to associate color with words.

The unusual title of the film, “Derek Tastes of Earwax,” actually describes the taste that James receives when he hears the word “Derek.” Fascinating views of the brain activity verify that the brain is seeing color for John even though he cannot physically see them while colorful graphics and animated sections illustrate what is physically happening to Dorothy when she sees colors with numbers. Extensive comments from researchers, physicians, a neuropsychologist, and the individuals with the condition (sometimes called “synesthetes”) help to create a comprehensive view of synesthesia. The film provides historical information and examines theories suggesting the causes of the condition. In fact, science is discovering that “synesthesia in varying degrees may be more common than originally thought especially in very creative individuals. In addition, the film demonstrates that technology for viewing brain activity as well as newly developed scientific tests help scientists document that the condition is a “sensory process” and illustrates progress in understanding that even with some genetic influence, the process is not simple.

The narration and comments by the researchers make complex theories less complicated for the viewer, and the actual comments from those affected by this condition add the layer of direct human experience to help the viewer understand. The original music, photography, and animated segments all complement the technical discussion to provide a creative approach to a difficult topic. This is an excellent addition for collections in psychology and health sciences and recommended for universities and large public libraries.
