If one does not pay enough attention to what is being learned or tries to multitask during encoding, the information in encoding courses will not be done correctly (Feist & Rosenberg, 2012). McNally (2007) wrote in his article that this process gone wrong could be a reason why psychologists misdiagnose AD. He says that just because you can't remember an important aspect of an emotional event doesn't mean you have dissociative amnesia. He argues that during an emotional situation, it is difficult to know whether or not the person has completely encoded the entire situation. One example he gives is that if a person is robbed at gunpoint, that person may not remember the attacker's face because they were so focused on the gun. There are then two types of encoding processes: automatic and demanding (Feist & Rosenberg, 2012). These are mostly as their names suggest. Automatic requires little conscious effort, while effort requires work (Feist and Rosenberg, 2012). An example of automatic is the clothes one wore the day before; an example effort would be traveling to states and capitals to learn them. Episodic memory uses automatic processing (Feist & Rosenberg, 2012). Semantic memory, in turn, uses effort
