comment How does the brain read rotated text?
Usually you don't come upon single letters, but strings of letters (words, text) and since those letters are arranged on the same bottomline you will easily understand how those letters need to be rotated in your mind to be understood.

I edited the question to make it more on topic for this site by deleting the moral philosophical terms and focussing on clinical psychology. If you disagree with my edit, @rajutikale, click "edit", then "roll back".

Btw, @AlexStone, where are those drawings from?

comment Can brain hemisphere activity/ dominance be inferred from the test subject's drawings?
The first image (with house) is really interesting. One figure drawing teacher asked me to do some figure drawings (after a live model) with my non-dominant hand. I noticed: in drawings with the non-dominant hand the proportions are intuitively accurate, while the lines are shaky and small details are therefore often misplaced; drawings with the dominant hand have straighter lines and better detail, but the proportions are usually false, often in a subtle way and hard to pin down. Don't know if that will give you any useful ideas, but those houses perfectly illustrate my experience.

I don't mean to imply that there is no decay, there obviously is or we wouldn't die. But people decay at widely varying speeds (and die at widely different ages), so maybe the extent to which cognitive decay depends on environment has been underestimated.

Hmm, SE keeps deleting @KeeganKeplinger from my comments. Why is that? (It stays here because I put it in backticks.)

comment Why do people get “too old to learn”?
I'm no expert in this, but I always had the impression that no researcher ever thought of comparing differnt kinds of old people: those that led lives that forced them to continually keep learning at the same rate as adolescents do (learning new languages, new skills, new social conventions etc., e.g. diplomats moving to new countries every few years) with those that learn a job and stick with it until retirement. Research has shown that training can make good about 10 IQ points. That's about what old people loose, compared to young!

comment How long does it typically take before a new environment starts forming part of one's dreams?
When I was a child, during the holidays I once rode a small ship to an island far out at sea. The waves were high, and the ship rode the waves like a bucking stallion. I dreamed of the ship's movement the following night. As an adult, I recently had to do a highly focussed, time consuming, monotonous sorting task. The following night I dreamed of what I did that day. In both examples, there was no delay for my dreams. But both dreams did not include people. I rarely dream of people I know, at least I don't remember any such dreams. So there may be a delay for dreaming of people.

comment Why do people get “too old to learn”?
There are recent personality theories that assume that personality traits are stable only because we keep our environments stable. We create our lives in a way that continuous change is not necessary. I wonder if something similar can be said about learning: we create our lives in a way that continuous learning is unnecessary, thereby reducing our ability to learn (because we have no practice and forgot how to learn, or because our "brain muscle" is untrained, or quite simply because we don't want to learn, now that we feel we know enough).
