What is memory?
ability to retain or store information and retrieve it when needed. (one of most feared aging changes, can be equated with illness, loss of independence, and/or death)
What is sensory memory?
information that is encoding by the senses and briefly processed. (decline in sensory encoding more related to quality of senses instead of age and leads to deficits in short and long-term memory)
What is short-term memory?
cognitive stage where info is held for 30 seconds (consciously aware of your environment)
What is primary memory?
information stored in memory through repetition for later recall (declines slow with age)
What is working memory?
relating/operating/using info acquired from sensory memory. perform complex memory tasks, application of info. (declines with age)
What is long-term memory?
information that is encoded/stored and can remain for years. (considered limitless in ability to store info)
What is declarative memory and the sub-parts of it?
- Semantic memory: stored facts, words, rules. (names, words)
- Episodic memory: ability to recall events. (a party, gathering, etc.)
What does the research say about substantial declines in working memory?
- 1) attentional resources (longer time to change between sensation focuses)
- 2) decline in processing speed
- 3) inhibit/filtering irrelevant information gets more difficult (getting rid of unnecessary information)
- 4) cognitive flexibility declines
- 5) stereotype threat
