If you do not pay enough attention to what you are learning or try to do multiple things at once while encoding, the information that is being encoded will not be performed correctly (Feist & Rosenberg , 2012). McNally (2007) wrote in his article that this process gone awry may be one of the reasons why psychologists misdiagnose AD. He states 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 assailant's face because they were so focused on the gun. There are therefore two types of coding processes: automatic and effortful (Feist & Rosenberg, 2012). These are mostly as their names suggest. Automatic requires little conscious effort, whereas effort requires work (Feist & Rosenberg, 2012). An example of automatic is what clothes you wore the day before; an example of commitment would be to go beyond states and capitals to learn them. Episodic memory uses automatic processing (Feist & Rosenberg, 2012). Semantic memory, in turn, uses effort
