Semester 2 psychology exam Flashcards
What is lifespan psychology?
the scientific study of human development from conception to death
What are the 3 different changes that people go through
Biological, psychological and social
identify the developmental stages across the lifespan
prenatal, infancy, early childhood, childhood, adolescence, early adulthood, middle adulthood, late adulthood
What is continuous development
development involves gradual and ongoing changes throughout the lifespan
What is discontinuous development
development involves distinct and separate stages with different kinds of behaviour occurring in each stage. You have to aster a stage before moving to the next one
Nature vs nurture debate
nature is heredity, genetics, and biological characteristics wheras nurture is the environment and experiences
Cross-sectional vs longditudinal studies
A cross-sectional study is an observational study that compares groups of different ages over a short period of time whereas a longitudinal is the same group over a longer period of time
cross-sectional studies benefits/limitations
B) not time-consuming
L) cohort effects
longditudinal studies benefits/limitations
B) long term effects can be studied
L)expensive;
time-consuming
participant attrition
difference between MZ and DZ twins
MZ share all genes/identical wheras DZ share half / fraternal
what are twin studies??
If MZ shows more similarity to each other than DZ, this shows that (nurture) genes influence the traits but if MZ and DZ share each other’s traits equally this indicates that the environment is the influence.
what are adoption studies
when you compare the child to their biological parents. If they are more similar to their parent, the genes is the influence but if they are similar to their adopted parent, then the environment which they grew up in is the influence of their behaviour.
What are the three theories of lifespan development
Piaget, Vygotsky and Erik Erikson
what is a schema
a cognitive structure/idea of what something is and how to deal with it.
What is assimilation
taking new information and making it part of an existing schema
What is accommodation
changing a schema to fit in new information
Example of assimilation, accommodation, schema scenario?
A child has a schema that a dog is a four-legged, furry animal with a tail. When the child encounters a cat, they assimilate and call the cat a dog. The child then learns that not all four-legged, furry animals with tails are dogs so they accommodate this information so they know there is a difference between dogs and cats.
Sensorimotor stage
coordination of senses with motor responses,
object permanence, ie. objects exist even if you cant see or touch it
What is object permanence?
understanding that objects still exist even if they cannot be seen or touched
pre operatiional stage
symbolic thinking- using symbols to represent objects
egocentrism, seeing things from another persons perspective
