Synaesthesia--a window into perception,

Synaesthesia–a window into perception, thought and language. Ramachandran, V. S., & Hubbard, E. M. (2001). Synaesthesia–a window into perception, thought and language. Journal of consciousness studies, 8(12), 3-34.

For example, tilted lines can be grouped and segre- gated from a background of vertical lines but printed words cannot be segre- gated from nonsense words or even mirror reversed words. The former is a perceptual difference in orientation signalled early in visual processing by cells in area V1; the latter is a high-level linguistic concept.

This seems like leakage between convolutional layers

Color areas (V4) and grapheme areas both in fusiform gyrus

My question: How does habitus fit in here? It’s the perceian context of sign-interpretaion

Lakoff and Johnson (1980) have sys- tematically documented the non-arbitrary way in which metaphors are structured, and how they in turn structure thought. A large number of metaphors refer to the body and many more are inter-sensory (or synaesthetic). Furthermore, we have noticed that synaesthetic metaphors (e.g., ‘loud shirt’) also respect the directionality seen in synaesthesia (Day, 1996; Ullman, 1945; Williams, 1976).

Putting these ideas together, we conjecture that the representation of certain lip and tongue movements in motor brain maps may be mapped in non-arbitrary ways onto certain sound inflections and phonemic representations in auditory regions and the latter in turn may have non-arbitrary links to an external object’s visual appearance (as in bouba and kiki).14 The stage is then set for a sort of ‘reso- nance’ or bootstrapping in the co-evolution of these factors, thereby making the origin of proto-language seem much less mysterious than people have assumed (see figure 8).
