Let us think about the various functions of the brain.
Once, photographs of Americans expressing various emotions were shown to the Fore people in New Guinea.
They readily recognized most of the expressions of anger, happiness, sadness, disgust, fear and surprise.
These six emotions are themselves universal. Some emotional triggers are universal as well.
For example, when something unexpectedly comes into your field of vision, you will be frightened.
But most emotional triggers are learned.
The smell of newly mowed hay will generate different emotions in someone who spent peaceful childhood summers in
the country and someone who was forced to work long hours on a farm.
Once such an emotional association is made, it is difficult to unmake it. But we can learn to manage our emotions better.
Another interesting thing is the relationship between the brain and fear.
For example, many people fear big snakes and run away because they feel danger.
But a baby usually doesn't feel afraid of a big snake, even if he or she is placed right next to it.
This may have something to do with the primary brain and its fear response to such dangers.
It seems likely that there is a tendency in the primary brain to fear natural phenomena that can hurt us,
but no tendency to learn to fear something that will not.
But this tendency is influenced by social experience.
Therefore, there is a good chance the baby will begin to fear snakes after watching other humans react to them.
