While most children can easy imagine themselves as astronauts , athlete or superheroes , make - believe might not be so promiscuous for the kids ' grandparents .
Researchers have long known that recalling memories of personal events is tough for older adult than vernal ones . Recent learning ability tomography subject have shown that people use the same mechanisms in the encephalon to conceive of as they do to remember , suggesting that old grownup may have as much worry imagining as they doremembering .
A fresh study , detailed in the January issue of the journalPsychological Science , enquire just that and found that younger grownup were right at tell details of past times , remembered events and future , made - up ones than old adults .
occasional memory
The kind of memories we call in when we call up past personal issue are called episodic memory . These are generally more vivid than other type of memory board and contain more pieces of information that can be replayed or relived in the judgement .
While other form of store , such as semantic memory , are more about remembering facts , occasional memory board are made up of the different pieces of information you commend from the effect : what you saw , what you heard , how you feel .
" So when you go to re - experience or think these case , you actually … your brain actually has to settle and describe and reactivate all those of bit of information and kind of bring them together into kind of a logical upshot that you remember , " said study leader Donna Rose Addis of Harvard University .
The hippocampus is the part of the brainpower responsible for hunting down all those pieces and putting them back together to form the memory . The hippocampus is known to showdecline in functionas a someone age , perhaps account for the loss of occasional memory board .
Neuroimaging studies paint a picture that when people imagined themselves in the time to come , they used interchangeable brain mechanisms as when recalling a memory . discipline of grievous amnesic who had bother guess also suggested a connection between the two processes .
" Our theory of how one put together a succeeding event is that you know , you take bits of information from preceding effect and you kind of recombine those and integrate them into some new scenario that has n’t happened before , " Addis explain .
one-time vs. youthful
Because honest-to-goodness grownup have a harder time arrange together the bits and pieces of memories , Addis and her fellow predicted that seniors would find imagining harder than unseasoned adult , " not only because they probably ca n’t discover the details in the first place , but then also to recombine them and mix them … into a meaningful kind of scenario might be difficult , " she toldLiveScience .
In Addis ’s study , participants were give a clew word ( always a noun — for example , " brake shoe " ) , and were then learn to either remember a past event or think a future one , within a certain time frame .
When the youthful adults recalled a past event , they were able to provide rich inside information about the scene and how they felt , Addis said , " almost like they ’re back there . " Older adult be given to tell more fact , with less optical oremotional particular .
The same happened when both grouping were asked to imagine a future issue — young adults tended to allow for more details from episodic computer memory , while older adults assure more fact .
Addis stressed that the findings are n’t saying that all older adults have no imaginativeness , but that " it ’s those people that have trouble recollect in item that also have difficulty ideate in detail . "
