New Research Shows That We Control Our Forgetfulness, Could Impact On Depresssion, PTSD

Have you heard the proverb "You only remember what you requirement to remember"? Now there is make clear that it may well be redress. New research from Lund University in Sweden shows that we can train ourselves to forget things.

The presumption that we human beings can command and intentionally forget unwanted memories has been controversial ever since Freud asserted it at the rise of the 20th century. Now, psychology researcher Gerd Thomas Waldhauser has shown in neuroimaging studies that Freud was chasten in his assumptions: in the like way as we can control our motor impulses (we be possible to for example rapidly instruct the brain not to clutch a cactus which is falling from a repast), we can control our memory.

Waldhauser's tests are carried completely in a laboratory environment where volunteers are asked to practise forgetting, or attempting to forget facts. Through EEG measurements, Waldhauser shows that the identical parts of the brain are activated whereas we restrain a motor impulse and whereas we suppress a memory. And fair as we can practise restraining motor impulses, we be possible to also train ourselves to repress memories, i.e. to lose the remembrance of.

Waldhauser points out several situations in what one. forgetting could be helpful. People endurance from depression often dwell on negative thoughts which might best be repressed or forgotten in commission for the individual to emerge from the despondency. The same thing goes for the public with post-traumatic stress disorder; the trauma makes it hard to be understood for the affected person to act rationally and to resolve his or her station. But the possible consequences of a deliberate check of memories are still not clearly established.

"We discern that 'forgotten' or repressed feelings many times manifest themselves as physiological reactions", says Waldhauser, who is attentive to point out that the volunteers were trained to forget neutral information in a controlled laboratory environment. Training to overlook a traumatic event would be in addition complex.

Waldhauser has not only shown that we be able to deliberately forget things. Through EEG measurements, he has moreover managed to capture the exact essential circumstance when the memory is inhibited, that is while the forgetfulness is imposed.

The check of memory eases off after a not many hours. But the more often complaint is suppressed, the more difficult it becomes to make amends for it, as Waldhauser has shown end studies in a laboratory environment.

"If the memories receive been suppressed over a long duration of time, they could be extremely intricate to retrieve", says Waldhauser.

Gerd Thomas Waldhauser has publicly defended his doctoral thesis, Behavioral and Electrophysiological Correlates of Inhibition in Episodic Memory.
