Some alters are what Dr Ross describes in Multiple Personality Disorder as 'fragments', which are 'relatively limited psychic states that express only one feeling, hold one memory or carry out a limited task in the person's life. A fragment might be a frightened child who holds the memory of one particular abuse incident.' In complex multiples, Dr Ross continues, the `personalities are relatively full-bodied, complete states capable of a rang of emotions and behaviours.' The alters will have `executive control some substantial amount of time over the person life'. He stresses, and I repeat his emphasis, 'Complex MPD with over 15 alter personalities and complicated amnesic barriers are associated with 100 percent frequency of childhood physical, sexual and emotional abuse.
