Q

Impacts of being old on thinking and decision-making:

A
  • The elderly use less optimal strategies
  • When there is a high degree of working memory required, older adults perform worse
  • However, in real world situations older adults have time to make decisions, they can rely on others and use strategies to help mitigate their decline
  • In general, older people are able to take more information in to account when making decisions
    -They have an increased ability to think in hypothetical ways and integrate life experiences
  • Integration of emotion
    better able to combine emotion and logic with their emotions take context into account

ex. An older person asked an ethics question can critically think about the issue better. Make choice combined with empathy, pragmatics and logic.

Q

What are 6 Age-related Differences in Decision-Making?

A
  1. Require less information to make a decision and search for less info (life experiences)
  2. Tend to avoid risk and choose safer options
  3. Use less details and just skip to “the bottom line” (get the gist of the information)
  4. Often feel overwhelmed by too much info or options
  5. May expect or rely on support from friends, family, and professionals for big decisions
  6. When asked to evaluate their options, they focus more on positive information rather than negativity

Q

What makes expert? What are expert traits?
When does expertise peak? What are age-related changes to epertise?

A
  • What makes an expert: How they handle a problem. Experts accumulate knowledge about alternate ways to solve problems or make decisions in their area of expertise.
  • Expert traits: more creative and flexible than novices, superior ability
  • Expertise peaks in middle age then declines
  • Age-related changes: Even if elderly people can no longer physically do the tasks they were once experts in, their reasoning usually stays expert

Q

What do Older adults do/need in order to learn?

A
  • Understand why they have to learn something
    *Enter with more experience
    *Be more willing to learn about more concrete things than abstract things
    *Motivated by real world factors-less by hypothetical situations
    *Be more motivated by internal factors (personal satisfaction) than external factors ($$)

Q

What are the two types of processing?

A

Automatic:
- Doesn’t require lots of memory or effort
- Includes Muscle memory
- It’s difficult to alter
- Some are prewired into the brain
- Often starts as effortful

Effortful:
- Higher demand level (takes more energy and attention)
- You are aware of doing the task
- Older people struggle more with these tasks -Why?- they suck at mental multitasking

Q

What are the 8 types of memory?

A

Sensory: 5 senses

Working: Holds and works with information in order to perform a task (ex. writing down a phone number you were just told).
- Worsens with age

Short term: Short-term memory briefly holds small amounts of information (don’t really do something with it)

Long term

Episodic: Daily life events (ex. what you ate for breakfast)
- old people struggle with this one the most
- personal events

Procedural: Muscle memory or ingrained, you don’t really think about it much

Semantic: Facts or knowledge (ex. how many months in a year)

Autobiographical: Knowledge about self
stronger when about memories with high emotions (last into old age)

Q

How is the encoding process effected by age?

A
  • This decline is related to a decline in automatic strategy use (ex. chunking, visualizing)
  • There are also changes in brain activity
  • You can see this on fMRI (evidence of compensatory brain activity)
  • Issues in encoding cause memory issues
    (can’t remember what you didn’t save)

Q

How is the retrieval process effected by age?

A
  • When you have issues encoding, you can’t retrieve
  • The prefrontal cortex and hippocampus communicate less (the retrieval process is slowed down and stuff gets lost in translation)
  • We have less extensive neural networks-sometimes the compensation they provide still isn’t enough to be able to retrieve a memory

Q

What are two things that help the aging brain stay healthy?

A
  1. Regular physical exercise!
    (big and strong-raw)
    - This reduces age related brain atrophy
    - increases neural plasticity
    - intervention alternative for diseases and normative decline
    - Increases grey matter volume
  2. Multilingualism
    - Protective against cognitive decline (the more languages the better)

Q

What are the primary aspects of the information processing model?

A
  • Study of how people take in things they see (stimuli) from their environment and transform them into memories
  1. Sensory Information input (downloading a file):
    - use the 5 senses
    - spacial awareness
  2. Encoding (making file into accessible format):
    - transforming info into a way that can be
    connected to previous memories or stuff they already know
  3. Storage (save):
    - Moving info into long term memory
  4. Retrieval:
    - Remembering

Q

What are the basic components of attention?

A

Attention is linked to the integration of processing in the parietal and frontal lobes
- This link changes with age
- Attentional processes are also influenced
by our ability to sustain our focus and the speed we can take in the information

Q

What is automatic processing? What is effortful processing?

A

Automatic processing: processes that are fast, reliable and insensitive to increased cognitive demands.
- prewired (never really needed attention)
- Hard to change
- Unaware of the process, don’t think about it
ex. Muscle memory

Effortful processing: requires all the available attentional capacity.
- task takes conscious attention
(takes effort)

Q

Why do older adults have reduced performance on attention tasks?
(Two Theories)

A

Inhibitory loss: They can no longer “tune out” irrelevant information when they are processing stuff

Attentional resources: Older adults struggle to divide their attention while multitasking on a complex task. They focus on the task that is more important to them, and performance on the other task suffers.

21
Q

What is working memory?

A
  • The processes and structures involved in holding information in mind while simultaneously using that information, to solve a problem, make a decision, or learn new information
  • We use rehearsal in order to hold information in working memory
    ex. repeat stuff over and over again
  • It declines with age but, more of a decline in spatial working memory than in verbal
22
Q

Within long-term memory, how do implicit and explicit memory, and episodic and semantic memory, performance differ across age?

A

Implicit: Effortless and unconscious recollection of information
ex. procedural memory that allows you to ride a bike
Minimal age effects

Explicit: Conscious and intentional recollection
More effected by age

Episodic: knowledge tied to specific events or experiences from our lives with contextual details about when, where, and how they occurred.
- lets us replay personal moments
- More emotion =more memorable
- stable until 55-60
-decline at 65
-binding deficit

Semantic: knowledge not tied to specific events
ex. facts language concepts
- increase 35 to 55
- decline 65 (not as much as episodic)

23
Q

What age differences have been found in encoding and retrieval?

A

Encoding:
- gets worse with age because of a decline in adult’s spontaneous use of strategies while learning new information
ex. grouping associating mental images, organizing information

Retrieval:
- If encoded poorly, can’t retrieve well
- Prefrontal cortex and hippocampus don’t work as effectively together
- less neuro network connections (must compensate)

**older adults process information differently in order to compensate for normal age related changes- The issue with memory is that these compensations aren’t enough

24
Q

What is long term memory?

A

Remembering something over time.

  • Not one specific spot in the brain - it happens kinda all over
  • Involves interactions among the prefrontal cortex, medial temporal lobe, and ventral posterior parietal cortex.
25
Q

What is procedural memory? What part of the brain does it depend on?

A
  • long-term memory responsible for storing information on how to perform tasks and actions
  • Implicit
  • Uses the cerebellum and basal ganglia
26
Q

What is a binding deficit?

A

Difficulty linking different elements of information together to form a cohesive memory or perception.

Ex. remembering individual events but struggling to remember how the details fit together

  • Older adults have trouble tying together the elements of an event to create a coherent memory
    (episodic memory)
27
Q

Why is semantic less effected by age than episodic memory?

A
  • Semantic memory isn’t as reliant on working memory, and so older adults can draw on their general knowledge easily.
  • Unlike retrieval or episodic memory semantics isn’t based on cues from original experiences, instead they are retrieved as facts we know about the world.

BUT:
- Can be hard to retrieve if you don’t use the knowledge very often
- More “tip of the tongue feeling” when trying to remember semantic memories as you age

28
Q

What is prospective memory?

A

Remembering something in the future
ex. I have an appointment Wednesday, November 6th at 330

29
Q

What are autobiographical memories?

A
  • Memories about ourselves and our experiences
  • Primarily a form of episodic memory (remembering temporal and spatial events from one’s past)
  • Little bit semantic (remembering facts about your passed-personal traits)
30
Q

What is source memory? What is false memory?

A

Source memory: Ability to remember the “source” of a memory and determine if it was imagined or a real experience.

False memory: When you remember something that didn’t actually happen

31
Q

How can we help older adults remember stuff?

A
  • Paying attention to incoming information
  • Relating the information to stuff we know
  • Encode so you can access it again
  • use memory aids or strategies
    Can use external aids (rely on environmental resources-notebook)
    Internal aids : memory aids - imagery
32
Q

What are the major types of memory self-evaluations?

A

Metamemory: individual’s understanding of how well they think they can remember things
ex. recognizing when you forget and using strategies
Memory monitoring: assessing the actual performance of one’s memory abilities, often focusing on perceived strengths and weaknesses rather than understanding memory processes.
active process of evaluating and assessing one’s memory (tests)-

33
Q

What is the difference between normative and non normative memory aging?

A

Normative: do not interfere with daily function
Nonnormative: do

34
Q

What are the connections between memory and physical and mental health?

A

Negatively effect memory:
Damage in brain (concussion or combat injuries)
Disorders like depression, ptsd, anxiety dementia
Seizures can damage hippocampus makes it difficult to remember new facts

35
Q

What nutrients impact memory?

A

b- vitamins
iron
flavonoids

36
Q

What are the three main conceptions of intelligence?

A

Problem-solving ability, verbal ability, and social competence

37
Q

Multidimensional vs multidirectional

A

Intelligence is multidimensional: intelligence exists across multiple dimensions (there are many domains of intellectual abilities)
Multidirectionally: distinct patterns of change in abilities over lifespan

38
Q

Interindividual variability

A

Adults differ in their intellectual development

39
Q

Mechanics of intelligence

A

refers to the underlying processes, structures, and systems that enable intelligent behavior

40
Q

Pragmatic intelligence

A

Every day intelligence grounded in sociocultural context
ex. particle problem-solving in everyday life

41
Q

What is the psychometric approach

A

Defined by performance on standardized test

42
Q

What is the cognitive structural approach?

A

An approach to intelligence that emphasizes the ways people solve problems and focuses on modes or styles of thinking

43
Q

What is Fluid intelligence?

A

When an individual is a flexible and adaptive thinker
declines throughout adulthood

44
Q

Crystallized intelligence

A

Knowledge acquired through life experiences and education
Improves throughout adulthood
ex. jeopardy
Learning that depends on basic underlying skills becomes more difficult with age while learning based on what we already know improves with age

45
Q

P-Fit model and intelligence vs The neural efficiency hypothesis

A

P-Fit model and intelligence: Intelligence comes from a network of neurons in the parietal frontal lobe
According to this theory, differences in intelligence are caused by differences in brain structure and function
There isn’t just one area in the brain that’s responsible for intelligence

The neural efficiency hypothesis, says that more intelligent people process information more efficiently.

46
Q

Why do the elderly learn differently?

A
  • Because they have a gain in experience based processes, but a loss in information based process
  • Information processing factors: decline in speed, working memory, and an inability to avoid distraction all impact intelligence and ability to process info
47
Q

What makes an older adult intelligent?

A
  • Personality: Positive beliefs and attitudes: support cognitive growth as does self-efficacy.
    Health: Brain injuries nutrition disease all affect brain function while physical exercise help it
    Sociocultural and lifestyle factors, such as occupation, socioeconomic status, stimulating environments, and strong social connections, are linked to better intellectual functioning and slower cognitive decline.
  • cohort differences:
  • Information processing factors: decline in speed, working memory, and an inability to avoid distraction all impact intelligence and ability to process info
48
Q

What are the main points in Piaget’s theory of cognitive development?

A
  • Assimilation: using stuff you know to make sense of stuff you are learning
  • Adaptation: changing your perceptions because of what you’re learning
  • 4 stages in the development of mature thought: sensorimotor (learning with senses), preoperational (egocentric-everyone is the same as them), concrete operational (some logic but no abstract), and formal operational (adult thinking).
49
Q

When does creativity peak?

A

middle age
