animal studies of attachment Flashcards
animal studies definition
in psychology these are studies carried out on a non-human animal species rather than on humans, either for ethical or practical reasons - practical because animals breed faster and researchers are interested in seeing results across more than one generation of animals
who did research on animal attachment
-Lorenz
-Harlow
ethologist research on animal studies in early 20th study
conducted animal studies of the relationship between new born animals and their mothers. their observation informed psychologists’ understanding of care-giver infant attachment in humans. one of the most ethologists was Lorenz
when did Lorez do research
1952
what did lorez do his study on
imprinting
when did lorenz first observe the phenomenon of imprinting
when he was a child and a neighbour gave a newly hatched duckling that followed him around
what was Lorez procedure
randomly divided a large clutch of goose eggs. half of the eggs were hatched with the mother goose in their natural environment. the other half hatched in an incubator where the first moving object they saw was Lorenz
what was Lorenz findings -observations
-the incubator group followed Lorenz everywhere but the control who hatched in presence of the mother followed her. even when the 2 groups were mixed the control group continued to follow the mother and experimental group followed Lorenz
lorenz findings
imprinting where a bird species that are mobile from birth attach to and follow the first moving object they see. Lorenz identified a critical period in which imprinting needs to take place. depending on the species this can be as brief as a few hours after birth or hatching. if imprinting does not occur within that time lorenz found the chicks did not attach themselves to a mother figure
what study on sexual imprinting did Lorenz do
relationship between imprinting and adult mate preference, he observed that birds could be imprinted on a human would often later display courtship behaviour towards humans
Lorenz 1952 sexual imprinting case study
described a peacock that had been reared in the reptile house of a zoo where the first moving objects the peacock saw after hatching were giant tortoise’s. as an adult this bird would only direct courtship behaviour towards giant tortoises. Lorenz concluded this meant the peacock had undergone sexual imprinting
what animal did Harlow work with
rhesus monkeys
why is Harlow’s study potentially better than Lorenz
because the monkeys are more similar to humans than lorenz’s birds
what did Harlow observe
newborns kept in a bare cage alone often died but they usually survived if given something soft like a cloth to cuddle
when did Harlow do research
1958
