ageing (test 1) Flashcards
What is the science of human development?
it seeks to understand HOW and WHY people of all ages and circumstances change or remain the same over time
What is the lifespan perspective?
an approach to the study of human development that takes into account ALL phases of life, not just childhood or adulthood
What are the age ranges for different stages of development?
infancy: 0-2 years
early childhood: 2-6 years
middle childhood: 6-11 years
adolescence: 11-18 years
emerging adulthood: 18-25 years
adulthood: 25-65 years
late adulthood: 65+ years
What is Rowe’s and Kahn’s definition of successful ageing?
they define successful ageing as the optimum state to be in the absence of disease and disability, high cognitive and physical functioning, and engagement with life
what are some problems with Rowe’s and Kahn’s definition of successful ageing?
- fails to take into account the sociocultural factors
- overly normative, not inclusive or those who fail to meet each criterion
- does not take into account subjective meanings by older adults (diversity)
- criteria are not well specified in the model
–> insinuates that people don’t have disabilities/diseases from the beginning
–> ignores the fact that many people come from disadvantaged backgrounds may not have the ability to achieve all 3 conditions of successful aging
what are the parts of healthy / successful aging?
- exercise
- social activity (includes social engagement / community)
- diet
- genes
- productive pursuits
what are the parts of the WHO model of active aging?
- economic determinants
- health and social services
- behavioural determinants
- personal determinants
- physical environment
- social determinants
what is the WHO definition of active aging?
the process of optimizing opportunities for health, participation, and security in order to enhance quality of life as people age
what is Active and Healthy Aging (AHA)?
a concept describing if older individuals around the globe are able to achieve active aging
what is successful cognitive aging?
cognitive performance that is above the average for an individual’s age group as objectively measured (able to adapt to the demands of everyday life)
what are the parts of successful cognitive aging?
- higher cortical thickness
- greater brain plasticity
- higher density of white matter
- faster encoding
- ‘super-aging’ phenotype
- improved network connectivity
what are selective experts?
people who pay less attention to things that aren’t personally meaningful –> become experts in a specific topic and focus on it
- keeps cognition active through aging process
what are super agers?
individuals ages 80 years and older with episodic memory that is comparable to, or superior than, that of middle-aged adults
What are the factors that promote successful aging?
positive psychology
- seeks to provide a greater understanding of the strengths that enable individuals and people to thrive (focus on the things in life that are good)
life satisfaction
- the overall assessment of an individual’s feelings and attitudes about their life (cognitive evaluation)
subjective well-being
- the individual’s overall sense of happiness (affective/emotional evaluation)
What is the paradox of well-being?
the concept that older adults maintain high subjective well-being despite facing challenges from their objective circumstances
–> expectation of aging vs. the reality of aging can be different
–> many older adults report higher well-being than younger people
why might older people have higher senses of well-being?
- may have developed coping strategies to reframe life events
- cohort effects; grew up with different expectations about their lives
- survival effects; more optimistic people have lived longer than those who have died in their generation
what are the models of subjective well-being?
social indicator model:
- suggests that older adults have less and so should be unhappier
paradox of well-being:
- suggests that older adults are able to overcome objective circumstances
set point perspective:
- suggest that people’s personalities influence their level of well-being throughout life (personality determines happiness levels)
what is an age friendly environment?
an environment that enables people of all ages to participate in their communities and treats everyone with respect
–> environment free of physical and social barriers
what is the communication ecology model of successful aging?
Communicative ecology model of successful aging (CEMSA)
- suggests that people’s OWN way of seeing and talking about themselves can influence the way they feel about aging
(higher self-efficacy –> greater chance to age successfully)
what are the 7 ideas of the CEMSA?
EXPRESS optimism about aging
DON’T USE aging as a reason for problems
AVOID applying age stereotypes to self and others
PLAN for the future
DON’T give up on new technology
LET others know ageism isn’t acceptable
DON’t be tempted by anti-aging products
What is the biopsychosocial model?
this model considers elements in each area of biological, psychological, and sociocultural factors that impact development and aging
Biological
- physical changes
- genetics (age, gender, etc.)
Psychological
- cognition
- personality
- emotional / mental health
- beliefs & expectations
Sociocultural
- social context (interpersonal relationships, social support, community)
- history
- culture
- socioeconomics
What are the four principles of adult development and aging?
(1) Changes are continuous over the lifespan
- a person’s appearance may change, but they still feel the ‘same’ (same personality as when younger)
(2) only the survivors grow old
- survivors managed to avoid the 5 major threats to a long life
(3) individuality matters
- people have different experiences that can impact their memory and brain development
- ex. hippocampal volume can be larger in a 70 year old than a 20 year old
(4) normal aging is different from disease
- losses: primary aging, secondary aging, tertiary aging
- gains: optimal aging
what are the 5 major threats to a long life?
- being overweight
- drinking and driving
- eating inadequate fruits and veggies
- being physically inactive
- smoking
What are the losses and gains of normal aging?
LOSSES:
primary aging:
- normal age-related changes
secondary aging:
- disease-related impairments
tertiary aging:
- rapid decline shortly before death
GAINS:
Optimal aging:
- changes that improve the individual’s functioning (things that become better with age)
What are the 3 categories of influences on development?
(1) normative age-graded influences
- ages that are expected to be associated with certain life events
- ex. ages when people are expected to move out, get married, have children
(2) normative history-graded influences
- events that occur to everyone in a certain time period
- ex. generational expectations ; expect all women to become mothers
(3) non-normative influences
- random events that occur throughout YOUR life
- ex. having a parent that dies when you’re young, covid pandemic
what are the divisions of the over 65 population?
young-old (65-74)
old-old (75-84)
oldest-old (85+)
what are the different measures of age?
chronological age:
measured by years we have been alive
functional age:
measured by how well a person is functioning (better than chronological age)
- biological age (ex. cardiovascular functioning, bone strength, cellular aging)
- psychological age (ex. memory, learning ability, intelligence)
- social age (ex. work roles, family status)
what is the difference between personal aging and social aging?
personal aging:
- changes that occur within the individual ; reflects time effects on the body
social aging:
- effects of a person’s exposure to changing environments
what is senescence?
a gradual physical decline that is related to aging
- body becomes less strong and efficient
what is life expectancy?
the average number of years of life that people born in a similar period of time are expected to live
what is life span?
the MAXIMUM age for a given species
- humans: 120 years
what is health adjusted life expectancy?
the number of years a person could expect to live in good health
–> AKA. ‘compression of morbidity’
- illness can be reduced if people become disabled closer to the time of their death
which countries are expected to have the greatest life expectancy ?
countries in Asia, Africa, and europe
what are the PRINCIPLES associated with each of the 4 principles of adult development and aging
(1) changes are continuous over the lifespan
–> CONTINUITY PRINCIPLE
the changes that people experience in later adulthood build on the experiences they already had in earlier years
(2) only the survivors grow old
–>SURVIVOR PRINCIPLE
claims that the people who live to old age are the ones who managed to outlive the many threats that could have caused their death at earlier ages (possibly more likely to care for their health / avoid risky behaviour)
(3) individuality matters
–> INDIVIDUALITY PRINCIPLE
claims that as people age, they become more different from each other (impacts development and the self)
(4) normal aging is different from disease
- means that growing older doesn’t necessarily mean growing sicker
what are the 3 models of developmental science?
(1) organismic model
- people are motivated to act on the world and the world responds back (any organism is the source of its own activity)
(2) mechanistic model
- people’s behaviour changes gradually over time, shaped by the outside forces that cause them to adapt to their environments (ex. taking apart a computer and looking at its parts)
(3) interactionist model (similar to niche-picking)
- claims that genes and environment interact and produce their effects on people, and people shape their own development (relational view ; how different aspects interact)
what are the sociocultural models of development?
(1) ecological perspective
- examines multiple levels of organization within the environment (sociocultural level)
(2) life course perspective
- looks at age-related norms, roles, and attitudes as influences on individuals (social ‘clock’ of expectations)
What are the contrasting lifecourse theories?
disengagement theory
- suggests that the normal/desired course of life is for older adults to ‘loosen’ their social ties (ex. preparing for death)
–> old & ageist model
–> assumes old people want to stop doing the things they used to do
activity theory
- claims that older adults are better adjusted and most satisfied when they remain involved in their social roles
continuity theory
- the individual’s personality determines whether activity or disengagement is optimal for them (a middle ground theory)
–> ties into niche-picking ; focusing on the things one DOES want to do
what is ageism?
a set of beliefs, attitudes, social institutions, and acts that denigrate individuals or groups based on their chronological age
what are the theories about where ageism comes from?
multiple jeopardy hypothesis:
- claims that older adults who fit more than one discriminated-against category (ex. women, minority group) are affected by more biases
terror management theory:
- suggests that people fear death and therefore distance themselves from older adults because they remind us of our mortality (defence mechanism against our fear of death)
modernization hypothesis:
- suggest that increasing urbanization/industrialization of western society is what causes people to devalue older adults
what are some theories as to why more adults aren’t negatively affected by ageism?
age-as-leveller view:
- proposes that as people become older, age overrides all other ‘isms’
inoculation hypothesis
- proposes that older minorities + women have become immune to ageism due to years of exposure to discrimination and stereotyping (not bothersome anymore)
what are the psychological models of development in adulthood?
Erikson’s psychosocial development theory:
- proposes 8 psychological crises stages that roughly correspond to age periods in life ; follows the epigenetic principle
–> principle suggests that each stage builds on the previous one
–> critiques: later stages can appear at earlier ages, and vice versa
Piaget’s theory of development
- claims that individuals gain in the ability to adapt to the environment through the processes of assimilation and accommodation
what are some biological theories of aging?
–> no single biological theory is widely accepted
programmed aging theories:
- proposes that aging and death are built into the hard-wiring of all organisms ; aging & death is part of the genetic code
–> ex. species differ in life spans, suggesting that aging is genetically determined
telomere theory:
- suggests that cells are limited in the number of times they can reproduce ; telomeres will shorten with age
free radical theory of aging:
- unstable oxygen molecules are produced
random error theories:
- proposes that mutations acquired over the lifetime lead to malfunctioning of the body’s cells
–> views aging as an accident resulting from cellular processes that have gone wrong
what do physical changes reflect?
physical changes reflect the influence of social factors, such as social class, gender, and income
what is the main thing that can impact aging?
lifestyle choices ***
what are the main changes in appearance?
- skin
- hair
what are the age-related changes in skin?
- fewer active hair follicles
- thinning of epidermis
- loss of elasticity & flexibility in tissue
- loss of subcutaneous fat
- age spots (due to sun-exposure ; photoaging)
