Animal Studies: Lorenz Flashcards
what did Lorenz test for
imprinting
how did Lorenz test imprinting
he took half of a gooses eggs
- the half he took saw him first when they hatched whereas the other half hatched as normal
- he then mixed all of the hatched geese and let them loose naturally
- the geese that saw him first, followed him around which meant they imprinted on him
what did Harlow study
the cupboard love theory
whats the cupboard love theory
the theory that infants only attach to caregivers because they feed them
outline the procedure of Harlows study
he put monkeys in two different cages
- one cage had a ‘comfort’ mother which was a wire covered in cloth
- one cage had just a wire monkey that didnt provide comfort but it provided food
- the time spent with the mother monkeys was recorded
- the monkeys were then scared by another mechanical monkey
- Harlow observed the actions of the monkey
what were Harlows findings
most of the time spent was with the comfort mother
the monkeys only went to the monkey with food when they were hungry
when they were frightened they went to the comfort mother
why are the findings of animal studies not generalisable
animals dont behave in the same way humans do since we have different biology and cultural experiences
what is a strength of both Lorenz and Harlows studies
they have been highly influential
- L: Bowlby also argues that theres a critical period
- H: Bowlby also argues thst infants crave comfort from their mothers similar to the macques
what are the practicsl applications from Lorenx and Harlows research
- immediate physical contact after birth
how did the geese lose the ability to imprint
if they didnt see a large moving object within the first 32 hours > meaning theres a critical period
why has Harlow been criticised for unethical grounds
he caused harm to the monkeys
they were frightened and this couldve caused mental disturbances
