Cultural conditioning is the process of influencing people's behavior through learning. For example, in Europe and most western countries, people eat with forks and spoons. To teach people that this is what they should use, they are given forks and spoons at a very young age, and told to use them. This is called childhood conditioning, as people learn appropriate behavior as children. In some cultures, making one's bed is considered a necessity and children are taught to make their beds.
Another form of cultural conditioning is adult conditioning. Adults may be conditioned to refrain from drinking too much if they are going to drive themselves home. If they do drink and drive, they may be arrested and fined, or even jailed.
Cultural conditioning can also happen by observation and imitation. For example, If one travels overseas and see that nobody gives any tip after eating at restaurants, then one can imitate other people and not pay any tip even if in one's home country a tip is expected after a meal at a restaurant.
Conditioning can be positively or negatively reinforced. Positive reinforcement is when a person is rewarded for good behavior based on the cultural values. Negative reinforcement is when people are punished if they engage in culturally untenable behavior. For example, a hug after scoring a touchdown in football would be positive reinforcement. Being thrown out of the game for cursing the referee would be negative reinforcement.
