Human development is
multidirectional, multicontextual (setting of events matter), multicultural (culture shapes how behaviour is viewed, intersectionality influences development), multidisciplinary (Biopsychosocial perspective), and plastic (capable of change/ can be altered. People can change over time but also be stable over time).
Age-related changes are…
- Universal- common to everyone
- Group Specific- shared by certain cohort or culture.
- Individual differences- resulting from unique events.
Interactionist model
encompasses both respecting the complex reciprocal interactions of nature and nurture.
Physical domain of development
Includes changes in size, shape and characteristics of the body
Cognitive Domain of development
Includes changes in thinking, memory, problem-solving and other intellectual skills
Social Domain of development
Includes changes in variables associated with the relationship of an individual to others. Your social expectations and roles change.
Scientific method
Curiosity, hypothesis, test, analyze data and report the results.
Cross-section study
observational studies that analyze data from a population at a single point in time.
Longitudinal Study
employ continuous or repeated measures to follow particular individuals over prolonged periods of time—often years or decades
Cross-sequential
a study in which two or more groups of individuals of different ages are directly compared over a period of time. It is thus a combination of a cross-sectional design and a longitudinal design.
Four goals of developmental psychology:
- Describe 2. Explain 3. Predict 4. Influence
Descriptive Methods
Case studies, Naturalistic observations, and Surveys
Experimental Methods
– Causal hypothesis and Random group assignment
Experimental group
Control group
– Independent and dependent variables
Quasi-Experimental Method
When you cannot assign participants
– Groups are naturally occurring
* Cross-cultural research
* Ethnography
– Comparing cultures or contexts
– E.g. – Margaret Mead’s work in Samoa
Ethics
– Protection from harm
– Informed consent
– Confidentiality
– Knowledge of results
– Deception?
Theories
- Bringing findings together to identify patterns.
- Produce hypotheses
- Help generate discoveries
- Guide research and practice
Developmental Theory
Framework for explaining the patterns and problems of development
Human DNA consists of units of heredity called
Genes
DNA is coiled and packaged into chromosomes; How many?
23 pairs
The genotype
specific genetic material and includes genes that are and are not expressed in the individual.
phenotype
the observed characteristic * It represents what you see in the individual.
Dominant-recessive pattern of inheritance:
a single dominant gene influences a person’s phenotype, but two recessive genes can produce an associated trait
Polygenic inheritance:
a pattern of inheritance in which many genes influence a trait
Multi-factorial inheritance:
affected by both genes and the environment
Mitochondrial inheritance:
children inherit genes from the egg, but not sperm
Epigenetics
how behaviours and the environment influence whether genes are turned on or off.
Some experiences can result in alterations in which…
genes are expressed
Some of these changes can even be…
passed onto the next generation
Parents create the child’s environment:
Genes and home environment
Children influence environment:
Temperament & heritable behaviours
Inherited traits influence interpretation
Temperament & pathologies
Evolutionary Developmental Psychology
- – Genetically inherited cognitive and social characteristics that promote survival and adaptation appear at different times across the lifespan
- – Newborns are genetically programmed with a predisposition to learn and develop in certain ways
- – Over our lifespan, we need to display different intellectual, personality and social behaviours to help us adapt and survive
Psychoanalytic Theories
Irrational, unconscious drives and motives, often originating in childhood, underlie human behavior.
Psychoanalytic theorists believe that:
developmental change happens due to internal, often unconscious drives
3 personality structures that develop over time:
- Id
- Ego
- Superego
Five Psychosexual Stages:
- – Oral (mouth) – 0 to 2 years
- – Anal (anus) – 15mths to 3 years
- – Phallic (genitals)- 3 to 6 years
- – Latency (period of dormancy)- 6 to puberty
- – Genital (genitals) – puberty to adulthood
- Fixed sequence
- Optimum development requires satisfaction of needs at each stage.
Psychoanalytic Theories – Erikson
- Development results from the interaction between inner and outer forces
- instincts and cultural demands
- Psychosocial stages focus on family and culture, not pleasure and sex.
- Development occurs across the entire lifespan, not just childhood.
- 8 “crises” or “dilemmas”
The Humanistic Alternative
- Deficiency motives - maintain inner balance
- Being motives – desire to understand and give to others
- The most important internal drive is wanting to grow and achieve their full potential (self-actualization)
Positive reinforcement
involves adding a “pleasant” consequence: Treats, attention/praise
Negative reinforcement
involves the removal of something “unpleasant”: Taking cough medicine removes your cough.
Positive punishment
involves adding something “unpleasant”, such as scolding
Negative punishment
involves the removal of something “pleasant”, such as taking away TV privileges.
Partial reinforcement
behaviour is reinforced sometimes (common in the real world)
– E.g. kids wanting attention
Shaping
complex behaviours are reinforced at steps
– Each step includes reinforcement
Extinction
is a decrease in behaviour after repeated non- reinforcement (e.g. ignoring it)
Cognitive Theorists
Cognitive theories emphasize mental aspects of development, such as logic and memory
Cognitive Theorists – Piaget
Piaget focused on answering the central question “How does thinking develop?”
Scheme
children’s repetitive actions, such as containing or positioning resources
