this video is going to look at reconstructive memory so your specification sets you've got to know about the theory of reconstructive memory including the concept of effort after meaning so the first part of this theory is that memory is inaccurate previously psychologists had believed that memory was an act of reproduction we store information after an event and we can recall it later with without altering it in any way possible but Bartlett challenged this he believed that we store fragments of information and then when we want to recall it we've got to build all these fragments up again into something that means something and the result is that elements are often missing and memories aren't an accurate representation of what really happened the next part looks at reconstruction according to Bartlet the information we store in our long-term memories gets changed before it's recorded So we record small pieces of information and later when when someone asks us to recall it we combine all these pieces to tell the whole story and every time you tell the story those elements get combined slightly differently he also talked about the influence of Social and cultural factors so our social and cultural expectations influence how we reconstruct our memories in the war with a ghost study for example people change parts of the story that didn't fit in with their own culture so in the story the young men was hunting seals but this was often misremembered as going fishing because that was more common for young British men who were retelling the story and also we've got that word on your spec effort after meaning so in the war of the ghost study what people recall was the General meaning rather than specific events although they did remember some specific events and bartler used the phrase effort after meaning to describe this what he meant was we focus on the meaning of events so when we're trying to remember something we remember the general meaning meaning and then afterwards we make an effort to interpret that in for more familiar terms in other words we try and make sense of those fragments but the main thing is remembering the meaning of whatever we're trying to recall or remember
