In the past couples weeks we have generally been talking about how our memory works. Memory is a construction process and it is really hard to tell whether or not they are actually remember true or it is just your mind constructing the memory which is two different things. Some people claim that they could remember most of the things that had happened to them when they were 1 year old, which is really impossible. In my perspective, what you are actually remember is different from what someone telling you and you just start to reconstruct other information and thought it was true and actually had happened. Before I was taking psychology I couldn’t tell the different because I thought I could remember something that happened to me when I was younger, but it was actually my parents who told me what it was and when someone asked me what did exactly happen when I was 2 years old I was just kind of repeat of what my parents told me. So the question is did I actually remember what happened when I was 2 years old? The answer is no. Construed memories are not memories of real events. The brain just makes things to fit by several fashion so memories are extremely malable and can be influence by different people such as place, words, smell etc. the most common is the real memory is not transferred from short term memory into longer term memory so not really ever known, yet when recalled the brain fills in the blank with something that was thought about relative to the situation being recalled. So it is really difficult to tell if someone is actually remember. But the average is most kids who can actually remember is around 3 years. If it is less than that it could be just a recreate that memory In your mind.
