For those people who preach there is no such thing as repressed memories, Stanford University has shown how the human brain actually blocks an unwanted memory, there is such a mechanism, and it has a biological basis. This discovery reinforces Sigmund Freud’s thesis about voluntary memory suppression.
The media over the past two decades, however, has done its best to support those who denounce this process of repressing memories by continually giving detractors a national voice. Their actions aid child molesters, and those who support them, in fighting against lawsuits filed against them by adult survivors of child abuse.
The Stanford researchers used brain imaging scans to identify the neural systems involved in actively suppressing memory. The core findings showed that controlling unwanted memories was associated with increased activity of the left and right frontal cortex (the part of the brain used to repress memory), which, in turn, led to reduced activation of the hippocampus (the part of the brain used to remember experiences). In addition, the researchers found that the more the subjects activated their frontal cortex during the experiment, the better they were at suppressing unwanted memories.
One of the researchers believes that these findings could also be used as a tool to better understand addiction and PTSD.
Even though the process of repressed memories has been validated scientifically, those who want to deny justice for survivors will continue to refute these findings. The problem is the deniers have no scientific proof of their own to support their denial.
