Animal studies Flashcards
who researched animal studies and attachment
Lorenz (1935)
Harlow (1959)
what animal did lorenz research in attachment
Geese
what animal did Harlow research in attachment
monkeys
what was the aim of lorenz’s research
to investigate how geese form attachments
what was the procedure of lorenz’s study into animals attachment
he randomly divided goose eggs into two groups
one group was left with the mother the other group were left in an incubator with lorenz
once hatched the 2 groups were brought back together and lorenz observed who they followed
lorenz also varied the amount of time the animals saw a moving object so he could measure the critical period for imprinting
what did lorenz find when researching attachment in animals
the gosling from the incubator followed lorenz in the same way as the other goslings followed their mum around
what is the purpose of imprinting in the short term
SURVIVAL
what is the purpose of imprinting in the long term
Formation of internal models for later relationships
what did lorenz conclude from his research into animals attachment
infants are affected by imprinting, this is where they attach to the first moving thing that they see.
this is 13-16 hours after hatching, after 32 hours (the critical period) it is too late for them to imprint
what were the aims of harlows research (1959)
to investigate whether baby monkeys would prefer source of comfort or food
what was the procedure in harlows research into animals attachment
16 baby monkeys were raised in isolation for 165 days
2 surrogate mothers were presented
one was made from wire mesh with a feed back bottle and the other was made of soft cloth with no feeder bottle
what were the findings in harlows research into attachment in animals
the monkey spent most of their time clinging to the cloth surrogate and onlu using the wire monkey to feed
these monkeys then grew up to be socially and emotionally disturbed
what was the conclusion of harlows research into attachment in animals
infanst form more of an attachment with the firgure that provides comfort and protection
growing up in isolation can affect development – more aggressive less social and bred less often, they neglected their young some evn killed their young
