Q
breathing and age

dispersal into bloodstream from lungs decreases about 4% per decade after 20 yo.
some adults might seriously impair their lungs by middle age

6
Q
the brain with age
A

- for about 1% of all adults, significant brain loss occurs before age 65
7
Q
neurons forming in adulthood
A
parts of the brain grow during adulthood
8
Q
dentate gyrus
A
specific area of hippocampus where new neurons settle, a region activated in forming new memories and exploring new places
9
Q
the senses over time
A
become less acute; brain compensates for loss in any one area by using other senses. tech and behaviour can help compensate

32
general intelligence (g)
Spearman
intelligence is one basic trait, involving all cognitive abilities, which people possess in varying amounts. it cannot be measured directly, but inferred from various abilities
33
components of intelligence
- fluid intelligence
- crystallized intelligence
- analytic intelligence
- creative intelligence
- practical intelligence
34
fluid intelligence
those types of basic intelligence that make learning of all sorts quick and thorough.
- working memory, abstract thought, speed of thinking
35
crystallized intelligence
the types of intellectual ability that reflect accumulated learning
- vocab and general info
36
analytic intelligence
remembering and analyzing various ideas; valuable in high school and college
- abstract planning, strategizing, focused attention, logic, verbal skills
37
creative intelligence
involves intellectual flexibility and innovation.
- imagination, originality, vision, appreciation of the unexplained or unusual
38
practical intelligence
intellectual skills used in everyday problem solving; experience advances it; crucial on the job and cannot be assessed by an abstract test

they have more and better strategies, esp when problems are unexpected
46
how are experts flexible?
they are creative and curious, deliberately experimenting and enjoying the challenge when things don't go according to plan
47
relationship between age and expertise is...
age and task related.
experienced adults often use selective optimization with compensation in becoming experts; the brain adapts as people become experts
48
family skills
important shifts have occurred lately ...
1) more women are working in traditionally male-dominated fields
2) domestic work has gained new respect
3) it is no longer assumed a "maternal instinct" is innate to every mother
