what is an adoptive triad
comparasion of characteristics between the child and their biological and adopyive parents
what does a twin studie allow us to look at
allows us to understand the difference between nature and nurture
what where level et al’s findings nature
birth mothers could show genetic risk for externilising problems in children
what where level et al’s findings nurture
adoptive mothers emotional state related to a child not shiffting attention
what was leve et als conclusion
genetic factors in a adoptive child can interact with enviromental influences within the adoptive family to produce behaviour
give a generalisiblity point of leve et al
:( population validityleve eta al used 360 adoptive triads adopted between the times of 2003-2006 for his research environmental and biological issues. however not every person is adopted of born between the time of 2003-2006t/f this makes his finding of behavior and shifting focus ungeneralisable to the wider population.
give a reliability point
:) standerdised questionsstanderdised questionairess where given out to all 360 adoptive triads on intelligance and antisocial behaviour of the child. t/f the findings on behaviour and shiffting attention are easy to replicate as cuae and effect has been established
give a validity point
:) holisticconsiders the interation of both nature and nurture, as behaviour child exhibits after hey where adopted ( betwee 2003-2006) is considered as well as factors like their jeanst/f this increases the validity of the study as we can gage a full understanding of why the child behaves in a certain way based of nature and nurture.
give an ethics point
:( informed consent a recruitment letter was sent round to families with asn opt-out card, however if participants did not fill this out then they would be considered as taking part in the study.t/f this could be seen as breaching the ethial guide line of informed consent as participants may have not fully understood the process of opting out of the study and so may have to participate against their will.
what was the aim of leve et als study
to investigate the difference between genes and enviroment on behaviour and how these interactions occour. to see if parental styles can interact with genetic factors of a child to influence behaviour
what was leve et al sample
360 adoptive triads born between 2003-2006
what was the procedure of leve et al study
questionaires and interveiws were given to birth and adoptive parentssalivary swaps collected fro children and participants 2 a day for three days adopted child did temprement tasks, parent-child interaction tasks e.g literacy taskscortisol swaybs 30 mins after waking up and 30 mins before going to sleep (6 collections)
what was leve et als sample
360 adoptive triads
when where they all born
2003-2006
