False memory syndrome (FMS) describes a condition in which a person's identity and relationships are affected by memories that are factually incorrect but that they strongly believe.
False memory is the psychological phenomenon in which a person recalls a memory that did not actually occur. False memory is often considered in legal cases regarding childhood sexual abuse.
In the lost-in-the-mall study, implantation of false memory occurred when another person, usually a family member, claimed that the incident happened. Corroboration of an event by another person can be a powerful technique for instilling a false memory.
The "Lost in the Mall" technique, or the "lost in the mall" experiment, is a memory implantation technique used to demonstrate that confabulations about events that never took place such as having been lost in a shopping mall as a child can be created through suggestions made to experimental subjects.
Recovered memory therapy is used to describe the therapeutic processes and methods that are believed to create false memories and false memory syndrome. These methods include hypnosis, sedatives and probing questions where the therapist believes repressed memories of traumatic events are the cause of their client's problems.
