Animal Studies Flashcards
who studied imprinting
lorenz
what does imprinting mean
an innate readiness to develop a strong bond with the mother, taking place during a specific time in development
what is sexual imprinting
the idea that imprinting can affect adult male preferences, animals will mate with the same object they were imprinted on
what was the procedure of lorenz study.
split group of greylag goose eggs into 2 batches, one hatched naturally with mother, one in incubator with lorenz as first thing they see, put all under upturned box, when released they ran to according person
what animal did lorenz use in his study
greylag goose
what were the findings of lorenz study
incubator goslings attached to him, the attachment was irreversible, imprinting took place in the critical period of 4-25 hours, when adults the goslings attempted to mate with humans
what was the implication of lorenz’s study for humans
Bowlby’s theory of attachment
- critical period (2 years)
- irreversible developmental consequences
what animal did harlow study
rhesus monkeys
what was the procedure of harlow’s study
measured the time each infant spent with the wire mother (providing food) and the cloth-covered mother (providing comfort) and the actions of the infant in response to being frightened
what were the findings of harlows study
the infant monkeys preferred the cloth covered monkey, only using the wired monkey to feed, using cloth monkey for comfort and reassurance when playing with new toys
what are the consequences of harlows study
infants develop an attachment to the person who offers contact comfort not who feeds them
what was the extension harlow carried out of his study
studied the monkeys deprived of a real mother into adulthood to test permanent effects of maternal deprivation
what were the findings of harlows extended study
motherless monkeys developed abnormally - socially and sexually
in what two ways did harlows monkeys develop abnormally
socially and sexually
how were harlows monkeys socially abnormal after the study
froze or fled when approached by other money, more aggressive, less sociable
how were harlows monkeys sexually abnormal after the study
abnormal mating behaviours - mated less than other monkeys and were unskilled
what can we learn from harlows extended study
there is a critical period of 90 days in which an infant needs to be introduced to a mother for an attachment to form, otherwise irreversible damage
