Psychology - Chapter 10: Developmental Psychology - important concepts Flashcards
Describe bi-directional influences and how these relate to human development.
Human development is a two-way street.
Experiences affect development and development influences experiences.
What is the major problem with cross-sectional designs?
What design rectifies this?
Cohort effects
Use longitudinal designs to get around this
Longitudinal effects measure what?
Describe.
True developmental effects:
- changes over time within individuals as a consequence of growing older
What are issues with longitudinal studies?
Costly and time-consuming
Not experimental designs - cannot infer cause and effect
What are externalizing behaviours?
Behaviours such as breaking rules, defying authority figures, and committing crimes.
What is attrition?
Participants dropping out of the study before it is completed.
What are two myths concerting development?
Infant determinism
Childhood fragility
What is infant determinism?
Assumption that early experiences - especially the first three years of life - are almost always more influential than later experiences in shaping us as adults
What is childhood fragility?
Holds that children are delicate little creatures who are easily damaged
What is nature?
Nurture?
Nature - genetic endowment
Nurture - the environments we encounter
What are the three stages of prenatal development?
What time frames do they run from?
Germinal stage - 0-2 weeks
Embryonic stage - 22ndd-9th weeks
Fetal stage - 9th week onward
Describe, briefly, the germinal stage.
Zygote begins to divide and double to form a blastocyst
During middle of week, cells begin to differentiate and organs start to develop
Describe, briefly, the embryonic stage.
2-9 week
Limbs, facial features, major organs begin to take shape
Spontaneous miscarriages occur most often during this period
Describe the fetal stage.
9th week
- embryo becomes a fetus
Major organs established
Physical maturation of fetus
When does brain development occur?
18 days after fertilization until late adolescence/early adulthood
What is proliferation?
Development of neurons at a very high rate
occurs from day 18 to then end of month 6
What are the obstacles to normal fetal development?
1 - Exposure to hazardous environmental influences
2 - Biological influences resulting from genetic disorders or errors in cell duplication during cell division
3 - Premature birth
What is premature birth?
Birth prior to 36 weeks gestation
What is the viability point?
Point at which infants can typically survive on their own - 25 weeks (typically)
What are reflexes?
Automatic motor behaviour
What are stage like theories of cognitive development?
Characterized by sudden spurts of knowledge followed by periods of stability
What are domain general theories of cognitive development?
Children’s cognitive development affects most areas of cognitive function at once.
What are continuous theories of cognitive development?
Gradual, incremental changes in understanding occur over time.
What are the ways in which cognitive theories of development differ?
1 - Stage-like vs. continuous
2 - Domain-general vs. domain-specific
3 - Primary source of learning:
- physical experience, social interaction, biological maturation
What are the different perceived primary sources of learning according to theorists of cognitive development?
Biological maturation
Physical experiences
Social interaction
