comment How to understand the other human being mentality, and also how to put an image/opinion of yourself on others?
I'm not sure empathy is something that can be learnt. Perhaps it can be fostered and facilitated (or diminished) if it's already present, but I'm fairly sure empathy is an evolved trait, hard-wired to occur in the population (to varying degrees).

comment Why do we find things fun?
I would consider them spandrels. In particular, byproducts of having evolved pleasure as a mechanism for driving behavior.

comment Where do our memories get stored and how are they retrieved again?
The "too broad" flag, to me, is more for technical how-to type questions that are the norm on the original stack exchange. I'm not sure if broad questions are so bad in a scientific pedagogical situation.

comment Difficulty of having profound scientific discussions with more than 2 or 3 people?
Sometimes, some of the people who are interested in the subjects may just want the discussion to be more open to people who are not as keen just to be polite.

comment Is there any evolutionary theory for self-destructive behavior?
perhaps you could backup your assertion about self-destructive behavior being a stress response with some literature. Explaining behavior in terms of evolution is very difficult. I also see two ideas here: giving up vs. self-destructive.

comment What is the mechanism explaining the effect of a positive attitude on immune system functioning?
@ArtemKaznatcheev, I have provided more evidence for this answer.

comment Why low audio frequencies seem to detune after an intense workout?
Hi hso, welcome to stack exchange. Could you possibly edit your question to be less anecdotal and apply more general to human cognition and neuroscience? I will answer anecdotally in my next comment.

comment is the mind independent of the brain?
I voted to leave this question open since it's such a common question from the public, but as the close votes indicate, you might consider doing some initial research and try formulating more specific questions based on that and let this one go.

comment Brain structures related to risk-taking behavior
Hi Ehsan. I'm withholding my vote to close this question to give you time to do some initial research and increase the quality and content of this question.

comment Should questions in psychology always be objective questions?
Phenomenology is a subject in philosophy that studies just that, but it's considered a philosophical aspect, not so much a scientific aspect.

Would you mind providing links and/or background information to clarify your question?

comment What exactly is the neurobiological mechanism behind the functioning of the human muscle?
More precisely, it's how much effort you put into a particular load. Precision manipulation requires a lot of activating and inactivating as you go back and forth writing, sharpening a spear, or tying a knot. So different muscles will engage at different times, so that's heavily recruitment dependent by its very nature. Lifting a heavy rock, you'll start out recruiting muscles, but once they've mostly been recruited, all you can do is increase firing rate.

comment Do you need sleep every night?
The "cleaning" hypothesis is just one, and it's a rather new one. The debate about the function of sleep has been going on for a long time, and the community has not settled on maintenance cleaning being the answer. There are also rest hypotheses (that neural cells need rest, but can't rest individually because they're coupled to other neurons, so they have to rest in large groups, requiring sleep) and there's also a hypothesis that sleep serves a memory and learning function (consolidation processes between hippocampus and cortex)

comment Is the Orch-OR Penrose-Hameroff model for consciousness sensible?
Short answer is no, I presented some of the evidence in my answer to a related question.

comment How would self awareness be limited without languages
Yes, I apologize. Pay walls for such information, often paid for by public taxes, are an annoying aspect of modern scientific culture.

comment How would self awareness be limited without languages
I believe the Sapir-Whorf hypothesis (known more generally as linguistic relativity) touches on this. You might also be interested in and outdated theory called Bicameralism. Probably wrong, but interesting and possibly still somehow relevant.

comment How would self awareness be limited without languages
Well, depending on what you accept as evidence, the infants of great apes are able to recognize themselves in a mirror before human infants can, developmentally, and it probably has more to do with self-monitoring circuits developing than language.

comment How would self awareness be limited without languages
do you literally mean self-awareness or do you mean consciousness in general?

comment Why do people get “too old to learn”?
Who do you think it is underestimated by? Society in general or researchers? I would argue that most people studying behavior account for it. The general method for teasing environmental from genetic traits is monozygotic twin studies. Here is one such study, Here is another, and Here is a review on the "use it or lose it" perspective.
