Question

How come we can remember a part of a memory but not the whole thing

In: Biology

Answer 1

There are multiple reasons for this. Generally we tend to remember what we deem is most important at the time. Whether that be because we experienced something particularly positive or negative – we generally have a desire to learn from our experiences. Smaller details that are deemed of no importance are often forgotten. If a memory is emotionally charged and overwhelming, there is also the possibility that we may block out certain details that are too distressing.
