Forgetting certain memories while remembering others may be a normal part of brain function, new research shows.
In
short, the very act of remembering may cause people to forget other
memories that are overridden in the retrieval process, according to the
study published in the journal Nature Neuroscience.
Researchers
from the University of Birmingham and the MRC Cognition and Brain
Sciences unit in Cambridge, England, discovered that intentional memory
recall isn’t as simple as mentally reawakening a memory. In fact, the
act of remembering can actually trigger the brain to forget other
competing experiences that interfere with memory retrieval.
“Though
there has been an emerging belief within the academic field that the
brain has this inhibitory mechanism, I think a lot of people are
surprised to hear that recalling memories has this darker side of making
us forget others by actually suppressing them,” study co-leader Maria
Wimber, PhD, says in a statement.
While
there are other studies on memory interference, researchers say this is
the first to isolate the adaptive forgetting mechanism in the brain.
It’s this mechanism by which remembering dynamically alters the aspects
of our past that remain accessible.More at link.
