What are False Memories?

An overview of the phenomena of false memories by Professor Christopher French, Professor of Psychology, Goldsmiths, University of London. Originally published on The Conversation website.

Recent media reports have raised questions over the therapy undergone by several people making allegations of historical sexual abuse against prominent public figures. In particular, it has been suggested that certain forms of therapy run a high risk of unintentionally generating false memories of sexual abuse. But why are there such fears around these kind of therapies?

Techniques to recover false memories – memories for events that are either grossly distorted or never took place at all – can include hypnotic regression, guided imagery, and dream interpretation, and are based on certain notions of how memory works. The therapists involved typically believe that memories for traumatic experiences are automatically banished to the unconscious mind as a defence mechanism. They also believe that, although such memories can no longer be consciously accessed, they still exert a damaging influence, resulting in a wide range of common psychological problems including anxiety, depression, eating disorders and low self-esteem.

It is maintained that the only way to deal with these psychological problems is to recover the repressed memories and “work through them” guided by a skilled psychotherapist. Such beliefs and practices are still commonly used both in the US and the UK. In fact, there is no credible evidence for the operation of this psychoanalytic notion of repression and very strong evidence that the conditions under which therapy takes place are indeed ideal conditions for the generation of false memories.

Forgetting trauma is rare

Evidence shows that, in general, traumatic experiences are much more likely to be remembered than forgotten There are some exceptions to this generalisation. For example, memories for any experiences that occur during the first few years of life are very unlikely to be consciously accessible in adulthood. This is due to the phenomenon of infantile or childhood amnesia. The infant brain is simply not physically mature enough to lay down detailed autobiographical memories at that stage of life. Similarly, physical trauma to the brain in adulthood, as a result of an accident or being attacked, may prevent the consolidation of memories of the trauma.

Even memories for other types of traumatic experience suffered later in life may be distorted and incomplete. Memory does not work like a video camera, faithfully recording every detail of an experience. Instead, memory is a reconstructive process. Every time we recall an event, our memory will be based upon some more or less accurate memory traces but the mind will often automatically fill in any gaps without us being aware of it. In general, we remember the gist but not the details.

But, under certain circumstances, we can develop entirely false memories for events that never took place. This remarkable counter-intuitive finding has been demonstrated in hundreds of well controlled scientific studies using a wide variety of methods.
