hey sorry to bother once again but i was flipping through my book its really doesnt touch much on the affects of ageing on memory
did you have a more specific question or shall i just summarise it?
basically, memory decline from aging is due to three main factors:
* CNS functioning slowing down
* Lack of confidence in memory
* Lack of motivation
These affect STM/Working memory:
* Simultaneous and Complex tasks are affected, whereas simple tasks are not.
* Rate and speed of processing declines
Also affect LTM:
* Procedural memories are the least affected
* Declarative memories are affected, semantic has no apparent decline whereas episodic does.
* Older people do not encode information with as much detail nor as precisly as younger people.
I don't think i have forgetting anything but Hope this helps.
