amnesia began. The capacity to recall past experiences m may vary, depending on the severity of the amnesia. e st
There are two types of amnesia: retrograde and ic anterograde. Retrograde amnesia refers to the loss of is memory of one's past, and can vary from person to per- ? son. Some retain virtually full recall of things that hap- er pened prior to the onset of amnesia; others forget only their recent past, and still others lose all memory of their past lives. Anterograde amnesia refers to the inability to recall events or facts introduced since the amnesia began.
Amnesia is not always obvious to the casual observer—motor skills such as tying shoelaces and bike riding are retained, as is the ability to read and comprehend the meaning of words. Because of this phenomenon, researchers have suggested that there is more than one area of the brain used to store memory. General knowledge and perceptual skills may be stored in a memory separate from the one used to store personal facts.
Childhood amnesia, a term coined by Anna Freud in the late 1940s, refers to the fact that most people cannot recall childhood experiences during the first three to five years of life. It has been suggested that this type of amnesia occurs because children and adults organize memories in different ways based on their brain's physical development. Others believe children begin remembering facts and events once they have accumulated enough experience to be able to relate experiences to each other.
