Many people who have emotional difficulties in adulthood, including addiction, wonder whether the cause was abuse in their childhood that they have forgotten or repressed. In particular, many wonder about the possibility of sexual abuse having occurred, but been blocked out.
They may have memories that are incomplete but feel uncomfortable, particularly when recalled with an adult perspective. If you are a victim of child abuse or know someone who might be, call or text the Childhelp National Child Abuse Hotline at to speak with a professional crisis counselor. For more mental health resources, see our National Helpline Database.
Not being able to clearly remember, particularly when there are hints that something may have happened, can be frustrating, and people can become quite distracted with speculating about what may or may not have happened to them, and asking themselves the question, " Was I sexually abused?
Hypnosis can seem like a way to unlock these memories and settle the matter once and for all. Unfortunately, the reality is not that simple. It is true that some people who were abused as children forget or dissociate from the experience, and don't recall the abuse in adulthood. This is thought to be a protective process. By forgetting the traumatic event, it is shut out of consciousness, allowing the child, and later the adult, to cope with current problems without being overwhelmed with unpleasant memories.
For others, troubling memories may occur on an ongoing basis. Both dissociation and intrusive memories are features of post-traumatic stress disorder PTSD. It is also true that some people later recall memories of abuse. This recall can occur in the context of some kind of therapy or change in physical or emotional state, including hypnosis.
However, recall of abuse can happen without any particular therapeutic intervention. At times, people who spontaneously recover memories of abuse are able to verify what happened to them, which can lead to a sense of relief and self-understanding.
At other times, the memories are not clear and are difficult to interpret. Seeking verifying evidence can also be impossible, fruitless, or can result in further difficulties with other family members. Hypnosis is an altered state of consciousness in which memories can sometimes be more easily accessed. However, it is also a state in which the mind is open to fantasy and imagination. It is virtually impossible to tell whether recall of an incident of childhood abuse is a memory of a real event, or a fantasy.
Many people, both clients and therapists, believe that memory works like a video camera, recording everything that happens to us. They may also believe that forgotten or repressed memories can be unlocked by a technique such as hypnosis. Rather, PHA reflects a temporary inability to retrieve information that is safely stored in memory.
That makes it a useful tool for research. Researchers have used PHA as a laboratory analogue of functional amnesia because these conditions share several similar features. Case reports of functional amnesia, for instance, describe men and women who, following a traumatic experience such as a violent sexual assault or the death of a loved one, are unable to remember part or all of their personal past.
In contrast, explicit memories are those we consciously have access to, such as remembering a childhood birthday or what you had for dinner last night. And, as suddenly as they lost their memories, they can just as suddenly recover them.
Forgetting in the Brain But for the comparison between PHA and functional amnesia to be most meaningful, we need to know that they share underlying processes. One way to test this is to identify the brain activity patterns associated with PHA. In a groundbreaking study published in Neuron , neuroscientist Avi Mendelsohn and colleagues at the Weizmann Institute in Israel did just that using functional magnetic resonance imaging fMRI. They carefully selected 25 people to participate in their experiment.
In the Study session of their experiment, participants watched a minute movie. One week later, in the Test session, participants returned to the laboratory and were hypnotized while they lay within the fMRI scanner. During hypnosis, people in both the PHA and non-PHA groups received a suggestion to forget the movie until they heard a specific cancellation cue.
For Test 2, participants were asked the same 60 recognition questions, but first they heard the cue to cancel PHA. So Test 1 measured memory performance and brain activity while the PHA suggestion was in effect and Test 2 measured memory performance and brain activity after it was cancelled.
But in Test 2, after the suggestion was cancelled, this memory loss was reversed. Somewhat surprisingly, however, the suggestion to forget was selective in its impact. Although people in the PHA group had difficulty remembering the content of the movie following the forget suggestion, they had no difficulty remembering the context in which they saw the movie.
What is entirely new in Mendelsohn et al. Consistent with what normally occurs in remembering, when people in the non-PHA group performed the recognition task and successfully remembered what happened in the movie, fMRI showed high levels of activity in areas responsible for visualizing scenes the occipital lobes and for analyzing verbally presented scenarios the left temporal lobe.
In stark contrast, when people in the PHA group performed the recognition task and failed to remember the content of the movie, fMRI showed little or no activity in these areas. Also, fMRI showed enhanced activity in another area the prefrontal cortex responsible for regulating activity in other brain areas. In revivification the subject appears to relive the incident as if it were actually occurring, and may even exhibit such characteristics as the personality, vocabulary, and handwriting of the earlier period.
Most strikingly, the memories following the age to which the subject is regressed become inaccessible. Because of the drama of television and the movies, many people who think about hypnotic regression have in mind this most dramatic form of revivification. In reality, most people who recover memories under hypnosis experience age regression primarily, with some moments of spontaneous revivification.
Hypnosis can also improve memory for people taking tests, memorizing lines, or seeking a mental edge professionally. This usually involves both posthypnotic suggestions from the hypnotherapist along with stress reduction, since stress hormones affect memory and critical thinking negatively. One final note regarding hypnosis and memory recall: with both age regression and revivification, the material recalled may be inaccurate.
A hypnotic subject can fabricate false memories on his or her own or at the suggestion of the therapist, intentionally or unintentionally. All rights reserved.
