what is developmental psych?
the study of how behaviour changes over the life span
what is gene- environment interaction?
the impact of genes on behaviour depends on the environment which the behaviour develops
e.g. of gene environment interaction
E.G. people who possess a gene that results in low production of an enzyme called monoamine oxidase are at a heightening risk of developing into violent criminals researchers discovered specifically children with both the low MAO gene and a history of maltreatment (e.g. abuse) were at heightened risk for antisocial behaviours like stealing, assualt and rape (children with only the low MAO gene were not at an increased risk
what i snature via nuture
genetic predispositoins can drive us to select and create particular environments, leading to the mistaken appearance of a pure effect of nature
what is gene expression?
= some genes ‘turn on’ only in response to specific environmental events
e.g. of gene expression
E.G. children with genes that predispose them to anxiety may never become anxious unless a highly stressful even triggers those genes to become active
what is epigenetics?
= whether genes are active is regulated by day-to-day and moment-to-moment environmental conditions
what is cross-sectional design?
a design in which researchers examine people who are of different ages at a single point in time
what is longitudinal design?
psychologists track the development of the same group of people over time
what is post hoc fallacy
= false assumption that because one event occurred before another event it must have caused that event, (A comes before B, A must cause B)
what are the 4 ways fetal development can be disrupted>
- premature birth
- low birth weight
- exposure to hazardous environmental influences
- biological influences resulting from genetic disorders or errors in genetic material
how do babies learn motor behaviours
trial and error
do heavier or lighter babies achieve milestones first?
heavier - more msucle to support weight
what is the benefits and issues with swaddling babies?
be- in China and Peru – infants are tightly swaddled in blankets that provide warmth and a sense of securiity but prevnet free movemnt of limbs
swaddled babies tend to fcry less and sleep more soundly – but swaddling slows the babies development

what is the piaget theory
how children construct htier worlds - first to pr4esent a comphresnsive accountof cognitive development
what did piaget attempt to do?
identify the stages that childern pass through on their way to adult like thinking
what was the greatest insight from piaget?
that children ae not minature adults
what is assimilation
the process of absorbing new experience into our current understanding
what occurs to a childs cognitive skills in assimilation?
during assimilation, the child’s cognitive skills and worldviews remain unchanged
what is accomodation
altering of the Childs beliefs about the world to make them more compatible with experience
what occurs inthe sensorimotor stage of development?
non though beyond immediate physical experience
what occurs in the preoperational stage of development?
Able to think beyond the here and now, but the egocentric and unable to perform mental transformations
what occurs in the concrete stage of development?
able to perform mental transformations but onl on concrete physical objects
