- The term gustatism comes from the Latin noun gustus (taste). It is used in *synaesthesia research to denote a hallucinated taste which is triggered by a sense perception in a different sensory modality. In accordance with the sensory modality involved, gustatisms are divided into categories such as optical or light gustatism, tactile or touch gustatism, pressure gustatism, kinaes-thetic or movement gustatism, and temperature gustatism. The term gustatism is used in opposition to terms such as * phonism, * photism, and * olfactism.ReferencesCytowic, R.E. (2002). Synesthesia. A union of the senses. Second edition.
