ATTACHMENT : LORENZ ANIMAL STUDIES Flashcards
What was Lorenz’s procedure
classical experiment
divided large group of goose eggs
half hatched with the mother goose in a natural environment
other half hatched with Lorenz in an incubator
of those that hatched in teh incubator who was teh first moving object they saw
lorenz
Findings
incubator group followed Lorenz
control group followed mother
when mixed up the group that saw first moving object be mother followed her and vice versa
What is Imprinting
bird species that are mobile from birth follow and attach to first moving object they see
What is the critical period for attachment to take place identified by Lorenz
depending on the species a few hours after birth/hatching
What happened if imprinting didn’t occur a few hours after birth
chicks didnt’t attach themselves to a mother figure
What did Lorenz also investigate
relationship between imprinting nd adult mate preferences
What did he observe about sexual imprinting
birds that imprinted on humans displayed courtship behaviour towards them
Let’s say a peacock was born into a zoo and teh first moving object she saw was ginat tortoises and only directs courtship behviour t giant tortoises we say she has undergone
sexual imprinting
WHAT ANIMALS did harlow study
Rhesus Monkeys
Why is it important he worked with rhesus monkeys
more simmilar to humans than lorenz’s birds
What did Harlow observe about contact comfort
newborns left alone in a bare cage died but survived if given something soft like a cloth to cuddle
what IDEA did harlow test
idea soft object serves some fucntions of a mother
outline harlow procedure
reared 16 babe monkeys
2 wire mothers
C1 - milk dispensed by plain wire madre
C2 - cloth covered madre dispensed milk
Findinfs of harlow
monkeys cuddled cloth covered mum as opposed to plain wire mothers
sought comfort from cloth wehn scared (noisy emchanical teddy)
regardless who dispensed
ehat did harlows research sho
contact comfot more important than food
when it cam to attachment behaviour
t/f harlow followed monkeys who had been deprived of real mothers into adulthood
t
why did harlow et al follow monkeys into adulthood
see if early maternal deprivation had a permanent effect
what did researchers find when they followe monks to adulthood
monkeys reared w plain wired mothers only - most dysfunctional
even monkeys reared with cloth covered mother didn’t develop normal social behaviour
deprived monkeys more aggressive
less socialbl
bred less - due to lack of mating skils
when becam mom neglected kids and even killed them
what was criticla period for attachment in monkey
mother must introduced to monkey in 90 dyas if attachemnt is to form
what happens after 90 dyas
attachment impossible
dmaage by early deprivation became irreversible
