Slides Week 1 Flashcards
Characteristics of Lifespan Development
- Needs
- Problems
- Possibilities that mark individuals’ progress from birth
to death.
Chronological Age
- Important to understand change over Lifespan
- Central to lifespan developmental psychology
Rules and Expectations About Age Related Behaviours
- Expectations about how people should behave at certain ages
- According to Culture, Historical periods and Laws
- Neugarten, 1973
- Social Clock - Cultural Norms
- Punishments for Violations
What do Developmentalists Do?
- Study behaviour, cognition and personality based on age of individuals
- from birth to old age
Three Age Related Changes
- Universal
- Biologically based so shared
- Group Specific
- Culturally Based
- Historically Based
- Cohort Effects shared by individuals in age group (Baby Boomers)
- Individual Differences
- Unique, unshared genetic and environmental influences
Development is . . .
- Lifelong
- Multidimensional
- Multidirectional
- Plastic - Has capacity for change
- Contextual
- Involves Growth, Maintenance and regulation of loss
- Co-constructed biology, culture and the individual
Three designs to study Age Related Changes
- Cross-sectional Designs
- Longitudinal Designs
- Sequential Designs
Cross-Sectional Designs
- Study groups of individuals of different ages eg: 18-24 years or 53 and older
- Advantages
- Fast and Inexpensive
- Can reveal age related change
- Disadvantages
- Reveals nothing about individual change over time
- Each participant is only tested once
- Cohort Effect - change may be due to another effect apart from age
Longitudinal Designs
- Follows same individuals over a period of time - 7-Up documentary or Grant study of Harvard Men
- Advantages
- Demonstrate sequences of change
- Show individual change or consistency
- Avoid cohort problem
- Disadvantages
- Costly
- Practice effects
Practice Effects
- Influences on test results when a test is taken more than once
- Occurs when you take multiple practice SAT exams; practice can increase your overall score.
Sequential Designs
- Combination of Cross-sectional and Longitudinal Desigsn
- Advantages
- Describes age differences and age changes
- Separate effects of age, cohort and time of measurement
- Indicates whether developmental changes are experienced by all in a cohort
- Disadvantages
- Complex
- Time Consuming
- Expensive
Six Methods to Collect Data when studying Age Related Change
- Case studies.
- Interviews.
- Observational studies.
- Psychological tests.
- Surveys.
- Physiological measures.
Case Study
- Detailed description of individuals being studied or treated
- Used to formulate broader research hypotheses
- Commonly used by clinicians, occasionally by researchers
eg: 7-Up or Psychoanalysis
Interviews
- Detailed descriptions of behaviour from a group of individuals
- Commonly used by qualitative researchers
eg: 7-Up, Piaget’s cognitive developent, Kohlberg’s moral development
Observational Studies
- Researchers carefully and systematically observe and record behaviour without interfreing with behaviour
- Naturalistic observation
- Laboratory observation
- eg: Bandura’s Bobo Doll experiments, Harlow’s Rhesus Monkeys
Psychological Tests
- Measure & evaluate
- Personality traits
- Aptitude
- Interests
- Abilities
- Values
- Types of Psychological tests
- Objective - NEO-Personality Inventory (Costa & McCrae 1992)
- Projective Personality Tests - Rorschach Inkblots
Surveys
- Battery of questionairres
- Useful when information needed from a large number of people
- Can be conducted in person, on-line or over the telephone
- Disadvantages
- Volunteer Bias
- Socially Desirable Responding
Physiological Measures
- Increasingly being used to assess development at different points of the lifespan
- Examples
- Blood Tests
- Skin Conductance
- Neuroimaging
- Electromagnetic waves used to consturct images of brain and biochemical activity
Human Developmental Theories
- Psychoanalytic
- Behavioral
- Cognitive
Psychoanalytic Theorists
- Sigmund Freud
- Erik Erikson
Behavioural Theorists
- Pavlov
- Watson
- Skinner
Cognitive Theorists
- Piaget
- Vygotsky
- Kohlberg
Freud’s Developmental Stages
- Oral stage - Birth to 1 Year
- Anal stage - 1 Year to 3 Years
- Phallic stage - 4 Years to 6 Years
- Latency stage - 6 Years to 12 Years
- Genital stage - Puberty onwards
Erickson’s Stages of Developent
- Trust vs mistrust - birth to age 1
- Autonomy vs doubt - age 1 to 3
- Initiative vs guilt - age 3 to 5
- Industry vs inferiority - age 6 to 12
- Identity vs confusion - adolescence
- Intimacy vs isolation - Early adulthood
- Generativity vs stagnation - Middle adulthood
- Integrity vs despair - Late adulthood
