Lecture 5: Introduction to the Lifespan Perspective and Socioeconomical Processing in Older Age Flashcards
What are the common perceptions vs reality of ageing?
-People (aged 16-64) expect aspects of life, such as memory loss, loneliness and being a burden to be prominent in later life (65+)
- Whereas people aged 65+ ranked their experience with these aspects at a much lower rate than expected
What is the stereotype effect? Lamont et al., 2015 Psychology and Aging
an ironic effect of underperformance on a stereotype-relevant task due to the anxiety that an individual feels about confirming negative stereotypes
e.g. it is widely assumed intellectual performance declines with age
——-> task performance d= 0.52
What did they measure for the Baltimore Longitudinal Study of Aging (BLSA)? Levy et al. (2009, 2015)
- Measured hippocampal volume
- Measured number of cardiovascular events (angina attacks, congestive heart failures, myocardial infarctions, strokes, and transient ischemic attacks)
- Measured many other possible factors to control for: age, BMI, depression, education, elevated blood pressure, family history of cardiovascular death, gender, marital status, number of chronic conditions, race, self-rated health, serum total cholesterol, smoking history
- All participants were physical healthy (i.e., no CNS disease, severe cardiovascular or pulmonary disease, or metastatic cancer) and free of dementia at first test
Internalizing effects of stereotypes have long-term consequences
What were participants asked to do in the Baltimore Longitudinal Study of Aging (BLSA)? Levy et al. (2009, 2015)
complete an attitudes towards old people survey
- including “Old people are absent minded” YES/NO
- “Old people are helpless” YES/NO
What were the results of the Baltimore Longitudinal Study of Aging (BLSA)? Levy et al. (2009, 2015)
Internalizing effects of stereotypes have long-term consequences
- participants who viewed ageing in a negative way (had negative age stereotypes) were more likely to experience a cardiovascular event (earlier)
- + more likely to lose hippocampal volume
What is the current global share of old people? (How many old people are there?)
- The global share of older people (>60 years) has increased from 9.2% (1990) to 11.7% (2013) and is projected to reach 21.1% (2050).
2 billion people will be aged 60 and older by 2050.
Why do we study ageing?
- Understanding the full picture of development
○ How does ageing impact on people’s lives?
○ What psychological and physical changes occur with age?- Consider methods that sustain/improve autonomy and wellbeing
○ How can different environments be adjusted to accommodate changes in physical and cognitive ability?
○ What tools can be developed to assist older people and accentuate the positive sides of getting older?
- Consider methods that sustain/improve autonomy and wellbeing
Development is a lifelong process – a full picture of lifespan development provides a more comprehensive understanding of human psychology and prepares us individually and societally for age-related changes.
Lifespan Perspective
Paul Baltes (1939-2006)
Development + Ontogenesis definition
- Development as change that lasts a lifetime
- Ontogenesis: individual development is the continuum in which changes are observed
an individual from birth to full maturity and death—and all the changes that come with that process
- Ontogenesis: individual development is the continuum in which changes are observed
What are the 7 theoretical propositions that characterise the Lifespan Perspective Paul Baltes (1939-2006)
- Development as a life-long
process- Multidirectionality
- Development as gain/loss
- Plasticity
- Historical embeddedness
- Contextualism as paradigm
- Multidisciplinary
Lifespan Perspective Paul Baltes (1939-2006) DEVELOPMENT AS A LIFE-LONG PROCESS
○ No age period holds supremacy in regulating the nature of development
§ e.g., child development
○ All stages of the lifespan, both continuous (cumulative) and discontinuous (innovative) processes are at work during development
EXTRA
- Life-long development may involve processes of change that do not originate at birth but lie in later periods of the life span (e.g., reminiscence and life review are examples of late-life phenomena/behaviours).
Life-long development is a system of diverse change patterns that differ in timing (onset, duration, termination), direction, and order.
Lifespan Perspective Paul Baltes (1939-2006) MULTIDIRECTIONALITY description
○ Even within the same domain, diversity or pluralism are evident in the directionality of ontogenetic change
○ The direction of change depends on the behavior
Even within the same developmental period, some systems of behavior show increases while others show decreases in functioning
Lifespan Perspective Paul Baltes (1939-2006) MULTIDIRECTIONALITY- basic information processing vs acquired knowledge
BASIC INFORMATION PROCESSING
- content poor
- universal, biological
- genetically predisposed
ACQUIRED KNOWLEDGE
- content rich
- culture dependent
- experience based
Lifespan Perspective Paul Baltes (1939-2006) MULTIDIRECTIONALITY- mechanics vs pragmatics of intelligence
MECHANICS OF INTELLIGENCE
- The basic architecture of information processing and problem solving.
- It deals with the basic cognitive operations and cognitive structures associated with such tasks as perceiving and classification.
PRAGMATICS OF INTELLIGENCE
- The content- and knowledge-related application of the mechanics of intelligence:
- fairly general systems of factual and procedural knowledge, such as crystalized intelligence,
- specialized systems of factual and procedural knowledge, such as occupational expertise, and
knowledge about factors of performance or skills relevant for the activation of intelligence in specific contexts requiring intelligent action.
Lifespan Perspective Paul Baltes (1939-2006) GAINS AND LOSSES- definition
There is a joint occurrence of gain (growth) and loss (decline).
- Lifespan development is not just simple incremental increases efficacy and growth—traditionally the view in early development. Furthermore, it’s not just loss/decline in older age.
Lifespan Perspective Paul Baltes (1939-2006) GAINS AND LOSSES- Traditional view vs current view
TRADITIONAL VIEW
There has been a string push to define the essence of ageing as a decline (e.g. a unidirectional process of loss in adaptive capacity)
CURRENT VIEW
Behavioural scientists tend to reject this view of a unidirectional decline of ageing because of their findings and expectations of some gains in old age
