Answer: Modeling and vicarious reinforcement
Step-by-step explanation:
When we are modeling a certain behavior from the person we take as our model there are steps we follow, we first pay attention to their behaviour: This is when Sharon notices that Kathy brings the assignment later but still the teacher accept it.
Secondly is retention of the behaviour we have observed: Sharon remembers that Kathy has done this several times then she can also do it which lead us to reproduction , Sharon now execute the same behavior in which she also brings the assignment later as did Kathy. Now lastly is the motivation to copy the behavior which is affected by what happened to the model.
If the behaviour was reinforced, we are more likely to imitate the behaviour this is referred to as vicarious reinforcement. Sharon saw that Kathy never get punished for bringing up her assignment later but the teacher always takes it which motivated her to do the same.
However, if the model got punished for the behavior you are less likely to imitate the behaviour and this is referred to as vicarious punishment.
