Good. Let's go next.

Is that all that environmental stimuli involves?

What is perceptual input?
What is biological input?

What do you mean by indirectly? Does it means that if have ever had any experience from external input than you're affected?

How to estimate dependency or independency between acting, decision making and environmental stimuli?

P.s Some questions can arise concerning sensory deprivation. How to consider actions and decisions influenced by sensory deprivation?

more or less yes.

What do you mean by indirectly? Does it means that if have ever had any experience from external input than you're affected?

Yes for example there was a study that found that many rape victims simply imagined the situation due to the terminology and group influence of other feminists.

How to estimate dependency or independency between acting, decision making and environmental stimuli?

Everything we do is dependent on environmental stimuli. It is impossible to be any other way. Hence why no free will.

P.s Some questions can arise concerning sensory deprivation. How to consider actions and decisions influenced by sensory deprivation?

Biggest question. Several pieces of research show that our memories are not even ours. We mix them up and reconstruct events based on current events and idea.

If it's taken so your definition of free will is false. Surely. My congratulations, you've debunked your own monster)))

Surely, i'm joking. As you could understand i'm not a proponent of the given definition in any way. Same way of thoughts by the way.

I should have stated the definition then to avoid misunderstandings. Language is such a volatile thing. It makes you wonder how it affects "free will" too ;)

Thanks for the link, but i prefer to read from original sources. Mostly the pop-sci articles appears after some considerable delay. There is much more you can get from scientific databases. Citations, similar and related articles. Without ads and all this commercial shit you know. A big quantity of articles are free of charge. When they are not than goes google and pop-sci))) And the most thing about that is that you can know methodology that was used and what criteria and data analysis lead to conclusions. As you have stated earlier not every study is real study.

I prefer to read papers from:
https://researchgate.net
https://www.ncbi.nlm.nih.gov/
http://www.jneurosci.org/
and so on...

I don't have open access to all journals any more. google scholar is a step away really. they often site the papers in the pop-sci articles.
