t seems quite strange that sometimes you don't even remember what food you had last night but some of your long ago memories are pretty clear in your mind. Have you ever thought of it that why such a thing happens?

According to a recent study led by psychologists at the University of Toronto, it is basically the preference that you give to a particular incident. The more you are concerned about an activity or a subject the more influence it lays on your life. And this finally decides that to what extent you can recall it later in life.

Rebecca Todd, a postdoctoral fellow in U of T's Department of Psychology and lead author of the study said, "We've discovered that we see things that are emotionally arousing with greater clarity than those that are more mundane. What's more, we found that how vividly we perceive something in the first place predicts how vividly we will remember it later on".

While explaining the concept, Todd further stated this life phenomenon similar to that of a flashbulb. The way its flash following its memory, illuminates an event, similarly the brain of an individual does. In medical terms, it is known as 'emotionally enhanced vividness'.
