animal study Flashcards
explain lorenz research
took gosling eggs, divided them into 2 groups, one left with natural mother, other placed in incubator.
when incubator eggs hatched, the first living moving thing they saw was lorez so they followed him around. we’re imprinted onto them
imprinted
following the first living moving thing you see
finding of lorenzs study
goslings divided themselves up, one following mother. noted that if a young animal is not exposed to a moving object during early critical period, the animal won’t imprint, suggesting animals can imprint of a constant moving object it seems within 2 days
long lasting effects for lorenz
process is irreversible and long lasting
effect on later mate preferences, called sexual imprinting. animals choose to mate with same object they imprinted on
harlow study
created 2 wire mothers, one with wrapped in soft cloth. 8 monkey studied for 165 days, for 4 monkeys tye bottle was on cloth mum and the other was for the plain mum. studied how long monkeys spend with each mom. they also scared it wity mechanical teddy bear
finding
all monkeys spent most time with cloth covered mother. spent short amount of time drinking milk then ran to cloth mum. when scared, they’ll clung to cloth mother, they’ll hold on for reassurance. infants develop attachment to person who offerers contact comfort
long lasting effects
socially abnormal froze or fled when approached by another monkey
sexually abnormal did not show normal mating behaviour, didnt cradle their own babies
however if monkeys spent time with monkey peers they can recover BEFORE 3 MONTHS
strength for lorenz
research support for imprinting - GUITON exposed chicks to yellow gloves while being fed, they became imprinted on glove. imprints on anuthing present during critical window, they tried to mate with glove showing early imprint is linked to later reproductive behaviour
limitation for lorenz
criticism of imprinting - guidon found that he could reverse imprinting in chickens thst tried to mate with gloves. after spending time with own species were able in normal sexual behaviour with other chicks
limitation of harlow
ethics of study - could not be done with humans so whether it should be done with monkeys, it created lasting emotional harm as they found it hard to form relationships.
strength for harlow
real world application - helped psychologists underdtand lack of bonding can be risk in children development m. research is theoretical and practical
