A kind of behavior by a person's action is called positive sanction and punishments in an action considered as negative sanction.
<u>Explanation:
</u>
The difference between positive sanction and negative sanction is as follows.
Positive sanction:
- An action that results in a 'particular kind of behavior' is known to be a positive sanction.
Negative sanction:
- An action of punishment or threat of 'punishment is used as a means to enforce conformity' is known to be a negative sanction.
The common point:
- Neither positive nor negative sanction works if people by themselves are not sure whether they should be rewarded or punished for a particular behavior. So, there is no common line between Negative and Positive sanction.
