Psychologist Lenore Terr, a defender of repressed memory therapy, argues that repression occurs for repeated or multiple traumas, such as a repeatedly abused child. Schacter notes that "hundreds of studies have shown that repetition of information leads to improved memory, not loss of memory, for that information." He also notes that people who have experienced repeated traumas in war, even children, generally remember their experiences. A person who suffers a great trauma often finds that she cannot get the event out of her mind or dreams. Terr's theory is that the child becomes practiced at repression to banish the awful events from awareness, and forgetting might aid in the child's survival. Her dissociative theory, however, is based on speculation rather than scientific evidence.
