So, certain sensory input invokes secondary sensory experience; for example, some people see specific colors in response to specific sounds.a neurological condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway.
And one comment that's similar to what I've read about intuitive brain development:functional neuroimaging studies have identified differences in patterns of brain activation...Psychologists and neuroscientists study synesthesia not only for its inherent interest, but also for the insights it may give into cognitive and perceptual processes that occur in synesthetes and non-synesthetes alike.
Famous synesthetes: Arthur Rimbaud (IxFP), Nabokov (xNxP), Nikola Tesla (INTP), Wassily Kandinsky (INTP), Charles Baudelaire (INFP), Marina and the Diamonds (ENFP), Billy Joel (xxTP?), Franz Liszt (ISFP), van Gogh (IxFP), Mary J. Blige (?)One line of thinking is that a failure to prune synapses that are normally formed in great excess during the first few years of life may cause such cross-activation.
The most common form of "synesthesia," in which graphemes are associated with experiences of color, is not synesthesia at all but an atypical form of ideasthesia. In synesthesia, the inducer and concurrent are both sensory, while in ideasthesia, the inducer is semantic. Everyone experiences ideasthesia to some degree.
[source]a phenomenon in which activations of concepts (inducers) evoke perception-like experiences (concurrents). The name comes from Greek, “idea”+”aisthesis”, meaning "sensing concepts" or "sensing ideas."
Both phenomenons obviously relate to the perceiving functions, and I'm really curious as to how. What do you think?
