Psychologists have found that memories of childhood experiences usually fade at the age of seven. This is often referred to as “childhood amnesia”.
The research involved parents of three-year-olds talking to their children about past events. The researchers then interviewed the same children again years later asking them to recall the events that occurred at age three.
The children between the ages of five and seven could recall 63% to 72% of the events while the children who were eight and nine years old only remembered about 35% of the events.
This is the first empirical study on the effect of “childhood amnesia”.
