Observation 1: Cognitive Development. In this episode, Cory says that he doesn't understand the emotion content of Full House, but Morgan exclaims that she does. From a Cognitive development perspective, she may not be understanding it as much as she thinks. Most preschool age children are not able to fully understand the plots, or even recall some of the details of the show. For Morgan, it may have been a way to seem smarter than Cory.
