Exam 6 - later life Flashcards
What happens when birth rates decline
the median age of nation rises
People link old age with
physical and mental decline
Who is guilty of ageism
everyone young and old
Positive qualities of old age
- Seen as better handling conflict resolution
- seen as less powerful - but seen as more gifted storyteller’s and wise
Median age
The age at which 50 percent of a population is older and 50 percent is younger.
Ageism
Stereotypic, intensely negative ideas about old age.
Cognitive abilities that get better with age
- Expanding crystallized skills
- Wiser
Divided-attention tasks
A difficult memory challenge involves memorizing material while simultaneously monitoring something else.
Memory with age
declines
Worldview on older vs younger people memory
Young people: due to external forces
Old people: Mental decline or memory illness
Are older people’s memory abilities much worse than younger adults?
Yes
As memory tasks get more difficult
the performance gap between young and old expands
Remembering in old people gets worse when they need to remember
- Come up with word or name on their own
- Recall a face or name and link it to a specific context
Elderly do poorly on what memory challenge
divided-attention tasks
Memory demands + time pressures =
deficits in the late 20s
Gateway system that transforms information into permanent storage
working memory
What is working memory made of
Executive processor -
- controls our attention
- transforms contents of temporary storage
Working memory as we age
- Improves during childhood
- Declines after 21
Why does working memory decline?
- Loss of synaptic plasticity in the hippocampus
- Deficits with the executive processor
- Exceptional trouble mastering divided-attention tasks
- Deterioration in the frontal lobe
When older people memorize easy tasks
they have a broader pattern of frontal lobe activity
When older people memorize harder tasks
they have under activation in frontal lobe
Memory-system perspective
A framework that divides memory into three types:
- Procedural
- Semantic
- Episodic memory.
Procedural memory
In the memory-systems perspective, the most resilient (longest-lasting) type of memory;
refers to material, such as well-learned physical skills, that we automatically recall without conscious awareness.
Semantic memory
In the memory-systems perspective, a moderately resilient (long-lasting) type of memory; refers to our ability to recall basic facts.
