Developmental Psychology Flashcards
__________________ ________________ is the scientific study of growth, change, and consistency through the lifespan.
Developmental psychology
In the context of life, _____________ _______________ is the scientific study of the changes that occur in humans as they age, from conception until death.
human development
In ____________ _______________, several factors are taken into consideration, such as personality, cognition, biological processes, and social interactions.
human development
What is longitudinal design study?
A group of participants are studied over a long period of time.
What is a cross-sectional design study?
Several different age groups are studied at one time.
What is a cross-sequential design study?
Participants are first studied by means of a cross-sectional design but are then followed and assessed longitudinally.
What changes do longitudinal designs typically study?
Mainly examines age-related changes.
What changes do cross-sectional designs typically study?
Mainly examines age-related differences.
______________ ______________ is where there is an impact on development occurring when a group of people share a common time period or common life experience.
Cohort effect
In which design is cohort effect likely to occur?
Cross-Sectional Design & Cross-Sequential Design
What changes do cross-sequential designs typically study?
Examines both age-related differences & age-related changes.
What is ‘nature’ in terms of development?
Nature refers to heredity, the influence of inherited characteristics on personality, physical growth, intellectual growth, and social interactions.
What is ‘nurture’ in terms of development?
Nurture refers to the influence of the environment on the same things and includes parenting styles, physical surroundings, economic factors and other possible external factors.
According to scientific research, which affects human development more? ‘Nature’ or ‘nurture’?
There is no definitive answer, after numerous years of scientific research, most developmental psychologists agree that all that people are and all people become is the product of an interaction between nature and nurture.
_______________ ________________ is a field of study in which researchers try to determine how much of behaviour is a result of genetic inheritance and how much is due to a person’s experiences.
Behavioural genetics
What are family studies?
Family studies typically measure many individuals from a large number of families on a particular behavioural trait of interest.
Researchers would then correlate the scores on the trait between family members (i.e. parents, siblings, grandparents, aunts/uncles, cousins).
What are adoption studies?
Tracks the presence or absence of traits in adopted children, among adoptive parents and biological parents.
What can be the conclusion if an adopted child shares a more similar trait or if there is a higher correlation between themselves and their adoptive parents?
It shows that environmental factors plays a greater contribution in that trait rather than genetic factors.
What can be concluded if the adopted child shares a more similar trait or there is a higher correlation between themselves and their biological parents?
It shows that genetic factors plays a greater contribution in that trait rather than environmental factors.
What are twin studies?
Compares the frequency of traits in identical twins (or monozygotic twins) who share 100% of genes and frequency of traits in fraternal twins (or dizygotic twins) who share approximately 50% of genes.
In twin studies for developmental psychology, their traits are being measured, but in what form?
They are being measured by the concordance rate, which is the percentage of twins in the study that share a particular trait.
In twin studies for developmental psychology, if there is a higher concordance rate in traits between the twins. Can it be concluded that the trait is definitively influenced by genetic factors?
Having a higher concordance rate does not equal to more evidence that the trait is more influenced by genetic factors, as external factors such as living environment also play a part.
_______________ is the science of heredity or the science of inherited traits.
Genetics
What is DNA?
DNA (Deoxyribonucleic acid) is a special molecule that contains the genetic material of the organism.
