Question 1

a)Age related changes in attention:

information processing model

Answer 1

cognitive processing is related to computer processing:information enters the system and is transformed, coded, and stored for later retrieval and use

Question 2

Information processing model

Answer 2

1st step: incoming information (any information from sight,sound,touch,smell,or taste)

2nd step: sensory memory :information is detected it is perceived by brain
held in sensory memory for a short period of time (limited information stored very briefly)
~Unattended information is lost

3rd step: attention

4th step: when we attend to that information it has possibility to enter short term memory
Information in short term memory may be rehearsed
It can be unconsciously rehearsed if you are constantly reminded of it or it can be conscious
Unrehearsed information is lost
Rehearsal leads to consolidation and encodes the information from short term memory into long term memory

Question 3

diffeent types of attention

Answer 3

sustained attention
selective attention
divided attention

Question 4

Sustained attention

Answer 4

Mackworth clock task: find when the red dot has been skipped

with age:reduced/preserved/improved performance (not much changes bc the task is easy)

Question 5

Selective attention

Answer 5

with age:Reduced performance

Question 7

Short term memory as a function of age:

Answer 7

primary memory:Passive store that holds information in the form in which it was received

working memory:Active store that allows for the processing and manipulation of information

Question 8

primary memory

Answer 8

Preserved performance with age

ie:Repeating a string of digits in the order in which they were presented

Question 9

working memory

Answer 9

Reduced performance with age(capacity to hold and manipulate info declines)

ie:Repeating a string of digits in reverse order, subtracting 2 from each digit

example:why do people put money in banks

preserved/improved performance

Question 20

Answer 20

Increase in fluid intelligence from childhood to 30, after 30 fluid intelligence declines and continues to decline across adulthood

Increase in crystallized intelligence from childhood to 30, shows slight increase after 30

Question 26

types of intelligence

Answer 26

practical, emotional, creative

Question 27

Practical intelligence/tacit knowledge

Answer 27

Capacity to solve problems that are poorly defined; are of personal interest and relevant to everyday experience; lack specific information; have multiple correct solutions, each with strengths and weaknesses; and can be solved using various methods

Improved performance with age

Workplace vignette; your goals are to become one of the top people in your field and get tenure

Question 28

Emotional intelligence

Answer 28

Capacity to understand one’s own emotions, regulate one’s own emotions, perceive others’ emotions, and use emotions to enhance performance

Improved performance ; with age we gain experience with emotions

Measured using rating scales; ie: i have a good sense of why i have certain feelings; i am able to control my temper and handle difficulties rationally

Question 29

Creative intelligence

Answer 29

1)creative potential: capacity to engage in divergent thinking (to think in different directions of topic of interest), generate many answers for a question and find novel solutions to a problem

2)creative accomplishment: productivity in generating creative contributions to a discipline

1)creative potential: preserved/improved performance

2)creative accomplishment: varies by discipline
Sciences and arts declines with age
Humanities slightly increases and peaks at 60-70

examples:
1)creative potential: how many uses can you think of for a brick?

2)creative accomplishment: quantity and quality of creative works produced in a discipline in a given period of time

What factors influence age-related changes in cognition?

Answer 34

stereotype threat

self-stereotyping

self-efficacy

perceived control

personality

intellectual engagement

education

occupational history

socioeconomic status

multilingualism

diet

physical activity

health conditions

Question 35

Stereotype threat

Answer 35

anxiety from having a neg stereotype imposed

associated with lower performance

Stereotype threat adversely affects older adults (especially in memory performance, self-reported health, self-reported loneliness, help-seeking behavior)

Question 36

2)self-stereotyping:

Answer 36

associated with lower performance

Self stereotype: tendency for members of a stereotyped group to adopt and assimilate to the stereotype of their group
~Involves explicit and implicit stereotype activation

Embodiment of stereotype can adversely affect cognitive domains including memory performance

Question 37

3)Self-efficacy

Answer 37

the belief that one can successfully perform a task; associated with higher performance

Higher self-efficacy on memory task leads to higher actual performance

Belief system influences our performance on cognitive tasks

Question 38

4)perceived control:

Answer 38

the belief that one can exert control to maximize performance on a task; associated with

Internal locus of control (belief you can control things in your life)-> higher performance on cognitive task

Internal locus of control-> implement strategies they believe will improve their performance (ie:more likely to engage in recall strategies )

Question 39

personality

Answer 39

openness to experience reflects curiosity, imagination, and creativity; allows for greater “environmental enrichment”; associated with higher performance

High in openness in experience tend to exhibit stronger cognitive capacity across older adulthood

Roughly 50% in variance of openness in experience is due to environment (we can change our levels of openness in experience)
