what was Lorenz researching

imprinting of goslings

What was Lorenz's procedure?

half of the eggs in the incubator were hatched with the mother half were hatched with Lorenz being the 1st moving thing they saw

define imprinting

goslings attaching the first moving thing they see

what is the critical period

if an attachment is not formed within a certain space of time one will never be formed

what is a goslings critical period

3 hours

what is sexual imprinting

goslings will try to mate with the same species as they have imprinted with

what are the ao3 points for Lorenz's research

strength - supports the theory of imprinting

. can be applied to other animals

limitation - imprinting cannot be applied to humans

. mammal imprinting system is more complex than birds

what was harlows research

worked with rhesus monkeys

studied that if they were put in a cage alone they often died

if they had something soft they survived

what did the monkeys chose in harlows research

they were given the choice of a metal figure with milk and a metal figure with a cloth

all the monkeys chose the cloth until they were forced to get milk

what were the findings of harlows study

the monkeys did not attach based on food but on comfort

what happened to the monkeys in later life

most never found a mate and reproduced

those who did neglected and killed their young

as they suffered from maternal deprivation

what is the critical period for monkeys

3 months

what are the ao3 points for harlows research

strength - real world application

. helped child development

limitation - generalisability to humans

. humans are more complex then monkeys
