comment Do feelings have a purpose?
I think you will run into great limitations in that analogy. Neurotransmitters change behavior based on far too many variables: rate of output, rate of uptake, and those are just a few of more. Also, medicine is exploring this: SSRI's are based on the idea that depression, and it's related feelings, are related to the rate of uptake of serotonin, such that it stays in the synapse and continues to activate neuron receptors. Of course, this isn't the full story...

comment Do feelings have a purpose?
You have multiple questions, which seem to confound each other: I'm interested if feeling in some way has a purpose. and Can we say something about the hormone/neurotransmitter levels based on how a person is feeling? are both good valid questions, but different enough to warrant different questions. With the first, you will run into anachronisms: anxiety functioned (and still functions) to keep us on alert for danger, but has been 'hijacked' by modern society to activate in incongruous situations. And the second is general: someone feels anxiety, and we know what anxiety is, but not why.

revised Does anxiety produce adrenaline or does adrenaline make the person anxious?

Thanks for the correction, I'll edit that out.

comment Is there a “foreplay” equivalent, priming activity for thinking or conversation?
Hmm...So I found a couple papers on the subject. At this point I'm not sure what your question has become. However, it seems that such activities are so wide-spread that they touch literally every human interaction (also, consider that such activities are likely unconsciously performed in many cases). This subject could potentially be a goldmine of research, if you pursued it.

comment Does anxiety produce adrenaline or does adrenaline make the person anxious?
"It makes sense but it is an infinite cycle. What is the false (and why), or if both are true then how does it ends?" - Both, and it's only an infinite cycle if you don't have a parasympathetic nervous system to modulate that adrenal response. But I don't have the references to make this an answer.

comment Is there a “foreplay” equivalent, priming activity for thinking or conversation?
I see two classes of situations here: 1) where there's an actual inhibition on one person's part, and 2) where people are in different states of mind (one is happy, the other sad). For the first, an icebreaker is needed to relax/ease their anxieties. For the second, 'conversation foreplay' is necessary to align the cognitive states of the participants. Without such an alignment activity, it would be very difficult to feel/process sympathy, empathy, or other socio-emotional connections. But this is just a theory on my part.

Also, I'll add that we're analog (signal) creatures, not discrete (aka digital) ones. When we do things, we are not on/off. We have to build up energy to overcome an activation barrier (this isn't just on the neuronal level, this paradigm exists all over). So for many people, a digital (or near-digital) shift to a different state can be very uncomfortable.

That's a different question: "what priming activities exist" vs "why is priming needed in the first place". Anyone could have any reason for social discomfort around strangers. Hell, with "stranger danger", kids are taught to be afraid of strangers. At the core, it's fear/anxiety, regardless of the cognitive reason behind it. But that's just for social discomfort. Turning the question around and using your foreplay example, what is "the ice being broken" there?

comment How does one study the effect of a dietary supplement on cognition?
There is a bit of information (and linked studies) at the Wikipedia page for Vinpocetine. Looks like a serious lack of information in general, but they have some basic information like half-life and bio-availability.

Often groups will use Icebreakers to ease conversation.

comment How does one study the effect of a dietary supplement on cognition?
Though most likely the lack of studies is the result of difficulties with performing well-controlled, longitudinal studies for common dietary supplements that marketers can make more money off of without scientific backing...(these statements are not FDA-approved).

comment How does one study the effect of a dietary supplement on cognition?
I think there is an issue here, in that "real psychoactive drugs" aren't meant to be taken for extended time periods (I mean, you can...). Whereas dietary supplements (and other 'medicines') are meant to be taken over an extended time-period to effect a change in self/personality/life after time. They can take time to build up in the body (think SSRI's, also).

comment Can we stop the brain from processing a particular task?
@H.Muster Certainly; however, I wouldn't be surprised to find that OCD is related to a malfunction of whatever causes that feeling of discomfort. Moreover, I suspect the OCD literature contains more resources for cognitive intervention techniques, in general, than other areas.

"prevent the uncomfortable feeling of "having an unsolved task"?" -- you may try looking into research on Obsessive-Compulsive Disorder (OCD).

comment How does the brain process concurrent visual or sensory data?
Your question is unclear... are you asking the difference between seeing something and visualizing that same thing? Or are you asking about attention and sensory inputs and how they coordinate on (un-)/(pre-)/conscious levels? You may control multiple things, but if you are doing it consciously (i.e. paying attention), I would suspect it's still multiplexed action...

comment Why a person may have a temptation to do something unrelated when doing especially important thing?
Related: en.wikipedia.org/wiki/Procrastination - tl;dr most likely some sort of anxiety

comment How does the mind build a model of reality?
I like this, but I think you've got too much going on at once here. I see at least 3 different questions (roughly the bolded parts) - you may get better results by splitting them up, even if they have overlapping background information.
