Thanks for your answer. Actually I'm looking for a field related to the both control systems and biomedical engineering...

Could you conceptually connect those fields to cognitive science in a way that makes it clear what kind of work it is that you are talking about?

make the question specific.

For example let's assume by means of cognitive science, we want to study human concentration on a subject and apply some disturbances and see how much it would distract him. So, is there any way to predict it's affect using control theories and apply some control signals, hence avoid disturbances to distract him?

Actually I'm looking for fields like this!

@Renzo Bianchi You are right... Thanks!

Well, one approach to your problem can be found in

Here humans act like the control-theoretical components!

@Roberta L. Klatzky awesome! Very appreciate by your help!

@ Kushal Kumar thanks for your reply ... would you explain more?

u should specifiy , but generally to do research taking tinto consideration cognition as a domain, there are clinical assessment, scales and imaging as objective reaserch tools.

The way you put your question doesn't make sense. Don't You have academic teachers that can help You to get started? Read a textbook on cognition and pick a field that interests you - don't follow the main stream.

may be quantum cognition as arising in my studies I expect to have some new promising features since such studies related the logical origin of quantum mechanics . This is the first time we find logic, perception, cognition interfaced ab initio with matter.

@ Elio Conte: i have to admit i don't understand a word you are saying(writing). All brain functions are based on "matter" - without the brain (1500 g of matter) no logic, perception, cognition etc..

by traditional science we were engaged to retain matter is here in this space and time --- res extansa .. as it was defined. Res cogitans is matter of matter entities traditionally considered to be involves in a res cogitans ... totally distinct and separated from res extensa.Quantum mechanics offers us a new scheme in which res extensa and res cogitans coexist ab initio in the same sctructure of reality as a God Giano two faces...

I apologize for the typewritten errors of my previous answer....res extens and not res extansa...... still.. res cogitans is matter of mental entities.. not res cogitans is matter of matter entities...

@ Elio Conte: to philolosophical for my limited brain matter based capacities. To my limited knowledge about the brain and its developement, cognition comes when the brain cells mature and build firm connections, and fades when  brain cells and firm connections deteriorate (look at child developement and dementia).

Let me add a satirical remark, coming from observation in real life (mainly politics, some science): there are many cum res extensa intracranialis, but sine res cogitans, but never vice versa.

I expect that we are not well understanding... may I suggest that we read the papers of my profile? As example .. On The Logical Orgins of Quantum Mechanics.... .... 

@ Elio Conte: as i wrote. i'm a simple doctor for nervous diseases with a background in brain research and special interest in Huntington's disease, so be no means i could understand what you are writing about on scientific grounds (maybe as a clinician?).

PS: who is "we"?

I am speaking about foundations of our reality. Cognition is a bsic dunamics function of our mental entities. We hope one day to understand their origin as well as the arising mental state in a human subject. To attempt to reach this objective a theory is necessary. One time we used classical physics giving a scheme of reality where matter is here with its properties as massa , velocity.... and mmental entiteis were conceived in an abstarct space-like.. suspended in an abstract configuration giving us so much difficulties to understand as they link matter. Here the matter .. there the observer that looks at the matter , measures it ,, ..... has perception of it. Here the objective matter , tere the subjective dynamics of the mental fatures of the human subject. After we had the advent of  anew physics that is called quantum mechanics . This theory gave a completely new scheme of reality  and , as I repeat, one basic feature is not the old dualism buut objective and subjective coeexisting AB INITIO in the scheme of our reality. I repeat ... se ON THE LOGICAL ORIGIN.......in my profile.. studies on quantum cognition have arisen .. and it delineates  teh folwwoing statemente ... during perception and cognition of human beings it seems that the foundamental principles of quantum mechanics have a role. An advance, if we aim to acknoledge it...

Can anyone please explain what Elio Conte is saying? 

The answer should not be difficult. Quantum cognition is a new field that may be found in the net and attempt to investigate....... I aplogize again.. for the difefrent errors in typewritten and conclude here my answers. Agian apologize but no more I can answer.

you might like to look at some models - Zimmerman and Cleary have some nice ones on processing

@ Mosahar Tarimoradi: what has transfer of sensory information to do with cognition?

One of the most promising questions re Human Cognition ( vast area) is re brain acting in a unified fashion. Efforts to specify localization - eg for ablation of ictal sites - have NOT met predictions based on localization theory. Instead, we've learned that the brain appears to act as a totality. However we are far from parsing this puzzle about how this totality might operate.  Pribram suggested in the 60's that the brain acts in a holographic fashion - this is still a useful starting point in my opinion.

In any case, we are ignorant about an essential anatomical and neurological brain description necessary to describe total brain activity; how does the Cerebellum interact with the rest of the brain? The cerebellum contains the same number of neurons as the rest of the brain - these are packed so densely that NO scan has been able to penetrate the cerebellum usefully. However, we're presently approaching the necessary resolutions to do so. THUS, I suggest that the study of Cerebellar Dynamics is the most productive area of current human cognition. 

Psychologist Paul McGaffey, PhD(ABD)

@ Paul O Mcgaffey: The cerebellum will most likely NOT be most important structure of the brain for cognition - as severe damage to the cerebellum has taught us decades ago.

I think, and not because it's mine of course, that the discovery of a fourth brain dimension is possibly the future of this discipline:

 Hello Herwig Lange. If you will see the good research by Dr. Jeremy Schmahmann and his colleagues re CCAS (Cerebellar cognitive affective syndrome), you'll be able to follow the argument I've made.

In agreement with Herwig Lange.

The first person to address would be a teacher or researcher at your own university. Another way would be to write a mail to any well known researcher or scholar in your field. Google e.g. Margaret Boden, who wrote a standard textbook on cognitive science. If you feel like sending a mail to such a person, just do it. Well known colleagues are often open to respond and are glad if they can help young scientists to get started. I happened to sit next to Margaret Boden at a conference dinner. That was just luck. I think by doing some research you should be able to find an institute or a scholar who you could write too. But a local contact is always better.

Hope this helps.
