Cards

Term
information processing model
Definition
assumes that people are active processors of information

information is processed through a series of hypothetical stages or stores

look quantitatively and qualitatively at info
Term
sensory memory
Definition
where new info is first registered.
has high capacity and fast decay.
ex) looking in a dark room and light goes on.
Term
encoding speed
Definition
how much info gets into sensory memory
Term
backward masking studies
Definition
shown series of letters instantaneously. covers the letters. younger adults do worse than older adults because they can't process the covering of the letters. (slower sensory memory replacement)
Term
CFF studies
Definition
light bulbs turned on and off. speeding up the process will look like a light moving. slower speeds for older adults. they don't process the light going off
Term
stimulus persistence theory
Definition
sensory traces persist longer in the nervous system of older adults. explains findings of those types of studies
Term
attention
Definition
mechanism that controls how much and what info is transferred from the high capacity sensory memory system to the more limited capacity working memory system
Term
selectivity
Definition
how we choose info we will process further. ex) simple visual search task/complex visual search task
Term
visual search task results
Definition
age differences are found for complex tasks. age decline in selectivity. more complex-->slower reaction time for older adults
Term
stroop test results
Definition
older adults have more trouble. more difficulty tuning out irrelevant info
Term
inhibitory loss
Definition
select what to attend to
Term
stroop test: baseline
Definition
move down the first column and then the second column naming the color of ink of each oval
Term
stroop test: test condition
Definition
as quickly as you can move down the 1st column and then the second naming the color of ink of each word.

older adults will be much slower and make more mistakes bc they can't tune out what's irrelevant
Term
capacity
Definition
how much info can be processed at any given time
Term
automatic processes
Definition
fast, reliable, insensitive to increased cognitive demands.
longer for older adults
processing a specific and repetitive task can make it an automatic attention response
Term
processing resources
Definition
amount of attention may decline with age
Term
divided attention tasks
Definition
measures capacity of attention
total decline in the total capacity of attention
each complex task takes more capacity for older adults
Term
vigilance
Definition
maintaining attention when performing a task over a long period of time
Term
hit rate
Definition
experiment: every time they heard a 7 and hit the button. misses would be when the 7 showed up and they didn't hit the button.

older adults have lower hit rates compared to younger adults esp for complex tasks

no age differences in the rate at which hits decline over time
Term
why are there age related declines in performance of complex attn tasks
Definition
cognitive slowing - slowing down on psycho motor tasks like RT tasks.
Term
psychomotor slowing (RT tasks reflect what?)
Definition
sensory memory, attention, some level of decision making, and motor response
Term
simple RT
Definition
response to one stimnulus. when see light press button.

older adults perform a lot slower. a lot are likely to have arthritis. motor time affected. biggest slowing = decision time (brain/neuro connections)
Term
choice RT
Definition
response to more than 1 stimulus, each with different response.

larger age differences than simple RT
Term
complex RT
Definition
like driving a car (speeding down or slowing down at yellow light)

the more complex the task, the larger the age difference in speed of performance.
Term
what causes psychomotor slowing
Definition
disrupted neural networks - To complete a RT task, a certain # of links between neurons is required. Because older adults have more dying neurons, neural messages are detoured and require more links, and therefore longer RT.

Cautiousness - Older adults may be more reluctant to make mistakes.

Slowed Motor Response - Does not seem to be a major factor.
Term
What factors can influence psychomotor
slowing?
Definition
Disease: can increase slowing
Exercise: may slow rate of decline
Practice: can help, but age differences are still
significant
Experience: Salthouse’s research on typists
demonstrates that on complex tasks anticipation can compensate for psychomotor slowing
Term
what causes accidents
Definition
the decline in sensory and information‐processing skills are the primary cause
Term
working memory
Definition
Information you are holding in mind and simultaneously using (small capacity)
Term
Rote Rehearsal
Definition
repetition
Term
Elaborative Rehearsal
Definition
Making meaningful connections between information in working memory and what you already know
Term
working memory
Definition
limited capacity

Plays an active, critical, and central role in encoding, storage, and retrieval

essential to performance on more complex cognitive tasks
Term
aging declines in working memory
Definition
slower rate of processing
more problems keeping irrelevant information out of working memory
less likely to organize information
spontaneously and less likely to use elaborative rehearsal
important implications for the later stage of Long‐Term Memory

younger adults spontaneously organize info where as older adults don't as often
Term
explicit memory (declarative)
Definition
intentional and conscious remembering of
information that is learned at a specific point in time
ex)remembering who wrote the Gettysburg address
Term
implicit memory (procedural)
Definition
unintentional. remember how to do something. ex) given list of words, not asked to remember

Retrieval of information without conscious or intentional recollection
An example is a language task such as stem completion.
Smaller age differences that explicit memory
Term
long term memory
Definition
Ability to remember an extensive amount of
information from a few minutes to a few years. large capacity
Term
episodic memory
Definition
personal memories that are remembered with time and place information

ex) what you did for your birthday
Term
semantic memory
Definition
word, concepts, knowledge not tied to the time the information was learned

ex) vocab association
Term
encoding
Definition
older adults don't encode as well. They are less likely
to spontaneously use elaborative rehearsal, categorization, and imagery. therefore, harder to retrieve info
Term
retrieving info
Definition
older adults do not retrieve well. result of encoding problems
Term
recall
Definition
remembering info w/o hints or clues
ex) essay test
Term
recognition
Definition
selecting previously learned
information from among several items

ex) vocab test

need retrieval for recall. adults don't do as well with recall tasks
Term
age declines in long term memory
Definition
worse when information is presented quickly,information is not familiar, or information is disorganized
Term
semantic long term memory
Definition
no (or small) age differences in knowledge based aspects of semantic memory

may be age‐related declines in the accessibility of semantic memory

Evidence for more difficulty for older adults with word finding and more TOT experiences
Term
episodic long term memory
Definition
Omit more information
Include more intrusions
Repeat previously reported information
Term
younger vs older adults
Definition
younger: explain in detail, accurate, no false info

older: forget info, more made up things, repeating what they said
Term
age differences in episodic memory for personal events
Definition
significant event = good memory
everyday events = not so good

hard to validate bc was based on event that wasn't observed by researchers

Bahricks’ study of yearbook photos suggests that older adults have good episodic memory, especially with a recognition test
Term
autobiographical memory
Definition
remember recent autobiographical events rather than older ones

more memories are chosen from late adolescence and early adulthood than middle or old age

“reminiscence memory bump” might be due to that time frame occurring when we start making unique personal identities
Term
reminiscence memory bump
Definition
due to the time frame occurring when we start making unique personal identities

most personally significant things (1st experiences) occur during young adulthood
Term
recency effect
Definition
come up with more recent memories; not linear curve bc of reminiscence bump
Term
personality development
Definition
occurs during teen/young adulthood years so that's why older adults think about it
Term
spatial memory
Definition
in route learning, older adults recall non-spacial associations and regard salient landmarks rather than turns. sequential processing constrained by cognitive capacity
Term
false intrusion
Definition
recall false info.

ex) mary was married to bob then linda married bob -> made inference that mary hated linda.
Term
prospective memory
Definition
remembering to perform a planned action in the future. hard for automatic/routine procedures. so automatic that you don't remember whether you have/haven't (locking door)

ex) remembering to take meds
Term
source memory
Definition
ability to remember the source of a familiar event as well as if the event is real or imagined
Term
false memory
Definition
when one remembers items or events that did not occur
Term
misinformation
Definition
older adults less accurate on source memory tasks, greater false memory effects
Term
biological approach to memory
Definition
deficit in memory from brain deterioration
Term
info-processing approach
Definition
age-related encoding deficit (organizational, elaborative, imagery processes) and retrieval deficit (strategies that help find stored info)
Term
contexual approach
Definition
Age differences in memory explained by
understanding the relationships among
characteristics of the task, characteristics of the
individual, and how the individual performs the task
Term
metamemory
Definition
knowledge about how memory works and what we believe is true about it
Term
age differences in metamemory
Definition
older adults seem to know less about how memory works than younger, expect that memory will deteriorate, and perceive they have less control over memory
Term
The Role of Memory Self‐Efficacy
Definition
older adults with lower memory selfefficacy perform worse on memory tasks

one may know a
good deal about how memory works, but still believe they possess low ability to perform a specific memory task.

older adults perform better when you tell them memory is in control
Term
normal aging vs. pathological memory loss
Definition
normal - exhibit only minor declines in
these cognitive functions

nonpathological memory loss - no interference with functioning in everyday life, so it is relatively benign
Term
Genuine memory deficits
Definition
problems that persist even after
individuals have been trained to use effective memory strategies. Can range from mild impairment to serious dementia
Term
memory strategies
Definition
Paying attention to incoming information
and making connections with stored information

Definition
ability to think rationally, act purposefully, and deal effectively with the environment. being successful in academic environment
Term
spearman theory
Definition
intelligence as a single ability, or "g". not a global characteristic of intelligence
Term
horn theory
Definition
crystallized intelligence = knowledge, judgment, understanding. doesn't change with age

fluid = perception, recall, drawing inferences, processing speed. raw thinking ability. declines with age
Term
thurstone
Definition
primary mental abilities - intelligence is several separate abilities
Term
wechsler adult intelligence scale
Definition

problem = there is one correct answer that is expected
Term
developmental changes in intelligence
Definition
in cross-sectional studies: the younger age groups weren't as different in average scores as older adults.
Term
classic aging pattern
Definition
WAIS - verbal sub-tests show little or no decline with age. performance sub-tests show more marked decline with age, esp for timed tests
Term
fluid intelligence
Definition
performance. flexible and adaptive thinking (eg. drawing inferences, abstract thinking, inductive reasoning)

declines with age bc of neurological change and/or disease
Term
crystallized intelligence
Definition
verbal skills. knowledge acquired through experience and education in a particular culture.

does not decline with age and may increase with life-long learning.
Term
summary of cross-sectional studies
Definition
Steady decreases in older age groups beginning in late adolescence

WAIS Performance subtests showed greater
decline than Verbal Subtests

Crystallized intelligence increases until one's sixth decade while fluid intelligence has a steady decline beginning in early adulthood
Term
results from longitudinal studies
Definition
Smaller decline starting later in life

Increases in IQ performance up to age 60, then abilities are usually maintained or have a small decline
Term
terminal drop
Definition
Tendency for psychological and biological abilities to exhibit a dramatic decrease in one's last few years
Term
longitudinal studies from age and IQ
Definition
minimize age declines in IQ because of selective drop out
Term
cross sectional studies in age and IQ
Definition
exaggerates declines because of cohort effects and because more people in the old groups may be experiencing terminal drop
Term
sequential research in age and IQ
Definition
better because of examination of changes in specific abilities

combines sequential and cross-sectional
Term
schaie's sequential study of age-related changes in 5 primary mental abilities
Definition
good data no one pays attn to. picked the wrong measure

verbal meaning, word fluency, number, spatial orientation, and inductive reasoning
Term
results of Schaie's study
Definition
People tend to improve on primary abilities until late 30s early 40s
Term
Tests used to assess IQ
Definition
Are the tasks relevant to older adults? What role does speed of response play in the scoring?
Term
occupation (factors that influence age and IQ)
Definition
Differences in cognitive skills needed in different occupations makes a difference in intellectual development
Term
Education/Cohort (factors that influence age and IQ)
Definition
Higher education and socioeconomic status also related to slower rates of intellectual decline
Term
Personality (factors that influence age and IQ)
Definition
High levels of internal control lead to positive changes in people’s perception of their abilities
Term
info processing (factors that influence age and IQ)
Definition
Perceptual speed may account for age‐related decline

Working memory decline may account for poor performance of older adults if coordination between old and new information is required
Term
Health (factors that influence age and IQ)
Definition
Those in good physical health can think, reason, and remember better

A connection between disease and intelligence has been established in general and in cardiovascular
disease in particular

The participants in the Seattle Longitudinal Study who declined in inductive reasoning had significantly more illness diagnoses and visits to physicians for cardiovascular disease
