I mentioned this in a recent post* and I wanted to ask a full question about it.
I don't want to go too much into medical details and I won't say more if asked.
Since birth, I've had problems with my vision due to eye conditions that I was born with. I was not allowed to have correction until age 12 due to my parents' beliefs. Usually, children can have it at age 2-3. The conditions, as well as the delay, undoubtedly negatively impacted early development of my Si and Se. Even with correction, because I also have difficulties with focusing my eyes, I find it difficult to stay focused on my surroundings for more than a few minutes at a time. So my S functions never had a chance to fully develop even after age 12.
I also have other sensory issues due to a condition that affects my nerves and my hearing (the hearing part is relatively minor on its own). It's hard to focus on bodily sensations when you are missing a lot of them or when you often get phantom sensations that aren't indicative of real sense impressions.
Because of these conditions, my sense perceptions are physically inhibited. My S functions seem weak and unrefined when I describe them in text, such as in a questionnaire. But I don't believe that they are truly weak or unrefined; they just lack the fullness and richness one would expect from an S type because they're inhibited from a lifetime of not being able to bloom due to physical limitations. Moreover, it's evident to me from self-observation that my Ni and Ne are truly weak, devalued, and barely conscious at the best of times, suggesting that these are my inherently weak functions. Moreover, I find it really difficult to engage in Ni or Ne, whereas I'm engaging in Si/Se basically all the time, it's just that the information they're learning is not as rich as it could be.
I'm curious if anyone can quantify the effect of sensory problems (of any kind, not just the ones I experience) on development of S elements? Or if anyone has similar experiences?
*For context, these issues came up here because I often struggle to decipher lines of text between which there is not much gap or contrast. The default font here is fine, I can manage, but a user had used a different font when replying to me and I had some trouble with the different font. I also struggle to read smaller fonts, but I can use the zoom features to get around that as much as possible. But if the contrast is not good or some unusual fonts are used then I can't zoom my way around it.
