My right eye is slightly myopic, but not severe enough to require glasses. I can focus my right eye if I cover up my left eye, given enough light. I think I read somewhere that if one eye has perfect vision, it can compensate for the other eye (as far as seeing things go anyway). So in my case, my left eye is probably compensating for my right eye (when I’m not covering up my left eye, that is).
I have a hypothesis: since my left eye is compensating for my right eye, my left eye is my dominant source of vision, so the best visual signals go through my right brain first (which isn’t so great at logical tasks, according to the lateralisation of brain functions).
What if I made my right eye become the dominant source of vision, either by fixing the myopia or by covering up my left eye (with a pirate’s eye patch, yaaaaar!), so that the visual signals go through the left brain first? Could I boost my performance at logical tasks this way?
I know I may be oversimplifying certain concepts, but it would be interesting if somebody actually did research and already have answers to this question.
Signals from each eye go to both sides of the brain. The left side of the visual field in both eyes goes to the right side of your brain, and vice versa.
Quite apart from that, the notion that the left side of the brain is more logical than the right is nonsense. Although there are functional differences between the two brain hemispheres, nearly all the stuff you tend to hear about left-brained versus right-brained thinking is entirely without scientific basis. It is pseudoscience.
IRT the above posters, a pirate’s patch would be OK for brain functioning then (and look pretty neat) but might alter your perception of depth a little. Maybe just wear it whilst carrying out the logical tasks?
A pirate’s patch will not have any effect on you ability to reason logically, or have any other significant effects on brain function, but it it will interfere with more than depth perception. It will sharply reduce the size of your visual field.
So far as I am aware, there is some legitimate science concerning certain functions differentially performed in the two hemispheres - not facts of tremendous significance to laypeople, or even psychologists, although neuroscientists and neurosurgeons need to know - and there is a bunch of nonsense based upon misunderstandings of the science, or on baseless and incoherent speculations as to its psychological significance (which is, in fact, close to zero). You seem to be saying that there is something in between. What?
Well, on that sort of criterion astrology would not be pseudoscience either. After all, it is based on real motions of the heavenly bodies, which really are both predictable and correlated with real and significant events on Earth, such as the changes of the seasons (and, thereby, with the agricultural cycle, and thus with the state of the economy). You are still not going to meet that tall dark stranger that your horoscope talked about, though.
In fact, I doubt whether anything would count as a pseudoscience on your criterion. Most wacky belief systems have some sort of basis in fact; it is just that the elaborate structures that are built upon those facts are not adequately logically connected to them, as is the case with stuff about left versus right brained styles of thinking.
