【题目】

Many studieshave shown us that our memories aren't completely trustable. It can be difficult to tell a real memory from a false one, but one kind of memories is tested to be unreal: anything "remembered" before age 2. According to a new study published inPsychological Science, nearly 40 percent of people are sure that they remember events before this age, but their brains are almost certainly lying to them.

There’s a reason you don’t remember anything from when you were a baby: Your brain just wasn't wired to record information that way. Infants (婴儿) use their memories when they first start to walk, talk, eat, and learn in general, but that all falls into the non-declarative memory category (非陈述性记忆范畴). Declarative memory, on the other hand, describes the events that happened to you, and it's specific to the hippocampus region (海马区) of the brain. For example, people with hippocampal damage can’t tell you much about their own lives, but they can still walk or talk.

In the first couple years of a child's life, the hippocampus is in overdrive. It keeps growing neurons (神经元) to make room for all the new information the young brain is absorbing. This is what allows babies to learn so much at such a fast rate, but it also means they have to sacrifice their long-term declarative memory. As new neurons form, old ones are pushed out, along with the autobiographical (自传体的)memories they stored.

It isn't until age 2 that this growth starts to slow down and the hippocampus becomes able to save declarative memories for a longer period. But adults can still feel sure they remember events from much earlier. When researchers asked 6,641 study participants to describe their first memories and say how old they were when they happened, 2,487 people reported memories from before age 2.

As these numbers suggest, it's surprisingly easy to believe the stories you tell yourself or that were told to you are true, first-hand recollections. For example, you clearly remember dropping your ice cream cone at the zoo when you were 1.5 years old. What's likely happening is that you're remembering the picture that played in your head when your parents shared their own memories of the event when you were a few years older, or maybe you saw pictures taken from that day and you formed false memories around them.

Memory doesn't become simpler as we grow up. Even people with super autobiographical memory are susceptible (易受影响的) to false memories.
