A] Three brains.

The variance in the level of development of brain brings the difference in the species. Human brain has 3 parts, and each has its own functionality and importance.

a] Old brain:

• Also called as animal brain, it handles involuntary actions of our body.

b] Mid brain:

• Also called as emotional brain, it reacts to everything with an emotions.

c] New brain:

• Also called as intelligence it controls intentional, purposeful and conscious activity.

B] Learning from experience is easier.

-Many of times learning from our experience or others is not perfect.

Because,

a] Complex situations.

b] Self experience.

c] Learning from mistakes.

d] Over generalization.

C] Performed, learned actions are easy.

• To perform any action for the first time, use our context we analyse the situation and understand it.

• We are completely conscious at each step and are constantly deriving conclusion about our actions.

• But once this experience is gained, it gets saved in our old and mid brain.

D] Problem solving and calculation are hard.

• Problem solving is the most intellectual process of a human.

• It requires control over most fundamental skills.

• Problem solving requires new neural patterns to be constructed, the process is always context based and occurs only during a necessity.

• Problem solving is a whole process which includes problem finding problem - shaping and problem solving.

• In simple forms, we can define problem solving as reaching to a goal from our current state.
