The desire for learning emerges from attempts to fulfil needs. When one needs to drink, she will use her current [[theory|theories]] to find [[options]] which will result an effective action which will result getting water which will fulfill the need of drinking (see brain [[Decision_making#Brain_process_involving_decision_making|decision making mechanisim]].

But if the need will not be fulfilled or either the actions and reactions will not go along the theory, then an [[RPE]]/[[falsification]] will cause the theory to lose corroboration and will secret dopamine which induce learning.

Learning can occur in several ways: In the first approach, we look for another option among those known to us. If we have not found another option, we can consult and try to learn from others or from various sources on possible solutions. If we did not find a satisfactory solution, we may have to investigate the matter, and expand our knowledge, so that we can create new options.

[[File:Learning Cycle.jpg|center|500px|thumb|Learning Cycle]]

Each of these options requires more cognitive resources then the one before. Therefore, we prefer first of all look for the possibility of that lies in our SON, then we will try to learn from others, and if it fails, we will be forced to spend resources on exploration and inventing new theories.

 +
This solution is suitable for ''doers'' who are driven be desires to fulfill physical needs. However people that tend to think more seems to have an addiction to dopamine and are less dependent on physical needs. These thinkers will be more eager to explore and less to learn from others or do.

==difference between experts and laymen in learning==
 +
Experts have more procedural knowledge, then laymen. When asked to solve problems, experts retrieve knowledge from long term memory to "long term working memory". Then they have to integrate current information to the working memory to result a solution. Laymen need to load both current information and procedural knowledge into the working memory, thus resulting higher load on the working memory.  This overload can be detected by the speed of the solution process, as well as the speed of finding the next step in the solution<ref>[http://www.anitacrawley.net/Articles/Kalyuga%20Measuring%20Knowledge%20to%20Optimize%20Cognitive%20Load%20Factors.pdf Measuring Knowledge to Optimize Cognitive Load Factors During Instruction.‏, S Kalyuga, J Sweller - Journal of educational psychology, 2004‏ - psycnet.apa.org‏]</ref>, and I think someone measured it by pupil dilation.

"Necessity is the mother of invention", William Horma, 1519

"No one Learn except that which his heart desires", Babylonian Talmud, Avodah Zarah, 19, 71, ~550 AC.

Learning Cycle

The desire for learning emerges from attempts to fulfil needs. When one needs to drink, she will use her current theories to find options which will result an effective action which will result getting water which will fulfill the need of drinking (see brain decision making mechanisim.

Need-theory-option-solution.png

She will then navigate her actions according to the theory/preferred option. If her need will be fulfilled then the theory will be corroborated.

Need-thory-option-corroborated.png

But if the need will not be fulfilled or either the actions and reactions will not go along the theory, then an RPE/falsification will cause the theory to lose corroboration and will secret dopamine which induce learning.

Need-theory-option-refutation.png

Learning can occur in several ways: In the first approach, we look for another option among those known to us. If we have not found another option, we can consult and try to learn from others or from various sources on possible solutions. If we did not find a satisfactory solution, we may have to investigate the matter, and expand our knowledge, so that we can create new options.

Learning Cycle

Each of these options requires more cognitive resources then the one before. Therefore, we prefer first of all look for the possibility of that lies in our SON, then we will try to learn from others, and if it fails, we will be forced to spend resources on exploration and inventing new theories.

This solution is suitable for doers who are driven be desires to fulfill physical needs. However people that tend to think more seems to have an addiction to dopamine and are less dependent on physical needs. These thinkers will be more eager to explore and less to learn from others or do.

Learning and deliberation

The normative principles of deliberation stem from the nature of communication, which is seen as an educative process where preferences are transformed rather than aggregated[1][2]. Discussions help to educate citizens and to make them more autonomous[3][4][5][6][7].

Learning at School

meaningful learning

Socratic dialoge

Socratic dialoge is more effective in learning then didactic teaching[8]. students explain their thinking out loud enhance their learning[9][10][11]. When using why questions and explist negative feedbeck, students learn more[12]

Learning in debate

In a study done on blamng Muslims of terror attacks, it was found that putting one self on the place of the other, can change attitude[13].

difference between experts and laymen in learning

Experts have more procedural knowledge, then laymen. When asked to solve problems, experts retrieve knowledge from long term memory to "long term working memory". Then they have to integrate current information to the working memory to result a solution. Laymen need to load both current information and procedural knowledge into the working memory, thus resulting higher load on the working memory. This overload can be detected by the speed of the solution process, as well as the speed of finding the next step in the solution[14], and I think someone measured it by pupil dilation.

Larning and Pupil size

Pupil response is governed by the autonomic nervous system. Pupil dilation depends on the activation of the adrenergic sympathetic nervous system, while pupil constriction depends on the cholinergic parasympathetic nervous system[16]. It has been well documented that pupil response is modulated not only by an ambient luminance level (the so-called pupil light reflex) but also by the amount of mental effort invested in a task [17][18][19][20][21][22][23][24][25][26][27]. For example, Porter et al[28] reported that the pupil dilates when subjects conduct a difficult visual search task in which high mental effort has to be invested.
