Then, there are people for whom time units evoke colours explains the researcher. It is also common for a synaesthete to see colours when listening to words, sounds in general or music notes (people who can see music, for instance). There are also cases, although fewer, where people can see colours in flavours, others perceive flavours or experience touch sensations when listening to different sounds, some link flavours to touch sensations, etc.
An permanent vision
These researchers from Granada underline that synaesthetes always experience the same vision, synaesthesia is permanent (a given stimulus always evokes the same colour for one person) and idiosyncratic (it is different for each person). Therefore, if for a synaesthete the word dog is red, every time he or she sees it, it will be perceived as red.
Even though synaesthesia has been known for a long time, its scientific study is relatively recent. Writings such as the Castel one, in which reference is made to previous studies about a synaesthesia case in a blind person, are found in the 18th century. The evolution of the study of this phenomenon has been spectacular the number of researchers working on this topic is constantly increasing, as will be evident in the Conference which will take place in Granada and, as the phase of proving that this phenomenon exists has been overcome, explains Alicia Callejas, we are starting to approach questions of major theoretical importance, and to develop adequate study strategies. The results of her research have been published in the following prestigious scientific journals, among others: Cortex, Experimental Brain Research and Consciousness and Cognition.
