memory U.3 L.10

people retain info for 15-30 seconds

rehearsal (repeating info after being presented), helps keep info in short term memory for longer

episodic memory : retention of info about when/where, younger adults have better episodic memory

autobiographical memory : personal recollection of events/facts first stored as episodic memory, reminiscence bump carries most memories from second/third decade of their lives, also found as carrying more positive events

semantic memory : persons knowledge about the world (field of expertise, general academic knowledge, everyday knowledge), independent of personal identity, researchers use vocabulary, general knowledge and word identification to asses it, tip-of-tongue (TOT) individuals cant quite retrieve familiar information

working memory : mental ‘workbench’ where people assemble/manipulate info (making decisions, solving problems, comprehension), perceptual speed : ability to perform simple perceptual-motor tasks

two types of long-term memory : implicit memory & explicit memory

implicit memory : affects thoughts/behaviours, procedural memory, unconscious or automatic (ex. unconsciously remembering how to drive), less likely to be affected by aging than explicit memory

explicit memory : ability to consciously remember what you wanted to buy

source memory : ability to remember where one learned something,failures of source memory increases with age in adult years

prospective memory : remembering to do something in the future (ex. running an errand)

beliefs, expectations & feelings have an affect on memory

non-cognitive factors on memory : health, education, socio-economic status

conclusions : decline occurs in episodic memory, perceptual speed, adapting to memory loss,
