Chapter 1 Flashcards
What is development?
Systematic changes in the individual that occur between the moment of conception and death
What are the goals of developmental psychologists?
to describe development across the lifespan
to explain the changes that occur during the lifespan
to optimize/improve development
What is the nature of development? What do we know about development?
nature is the influence of the genes that people inherit.
development is multidirectional, multicontextual, multicultural, multidisciplinary, and plastic
Explain multidirectional
Change occurs in every direction, not always in a straight line. gains and losses, predictable growth, and unexpected transformations are evident
Explain multicontextual
human lives are embedded in many contexts, including historical conditions, economic constraints, and family patterns
Explain multicultural
many cultures, not just nations but also within them, affect how people develope
Explain multidisciplinary
scientists hesitate to apply general conclusions about human life until they are substanted by several disciplines, each with specialization
Leads to better treatment
Broadens and deepens the perspective of every scientist
Explain plasticity
every individual, and every trait within each individual, can be altered at any point in the life span. change is ongoing although it is neither random nor easy
Can be modeled, yet maintain durability of identity
Bronfenbrenner’s levels and contexts
levels
microsystems- each persons immediate surroundings
exosystems- local institutions (church and school)
macrosystems- larger social setting
chronosystem- time (historical context)
mesosystem- connection among other systems
Contexts
historical context- cohort: group of people who share historical events because they were born at the same time
socioeconomic context- Social class is determined by income, wealth, occupation, education, and living place
Steps in the scientific method
Step 1- Curiosity Step 2- Hypothesis Step 3- Test Step 4- Analyze data and draw conclusions Step 5- Report results Step 6- Replication
Method of collecting data
observation- record behavior systematically and objectively
experiment- establishes what causes what
survey- quick and direct but not accurate
case study- interview
Types of research designs
correlational- association
experimental- he researchers tries to learn the cause and effect relationship btwn. Two variables; typically impose a particular treatment w/ volunteers and see whether or not it is successful
cross-sectional- pro: quickest and least expensive. con: Age discrimination
longitudinal- pro: traces development over many years. Cons: participants may withdraw, participants become knowledgable about the study and less valid, historical context changes
cross-sequential- pro: disentengle the effects of age from the effects of history. Con: difficult
cross-sectional
collect data once from different ages in the same day. compare groups. any differences are the result of age
longitudinal
collect data 5 times, at 4 year intervals. any differences are the result of time
cross-sequential
collect data 5 times, adding a new group each time. first compare same age, different times. then compare same group as they got older. then same people as they grow older
