animal studies - Lorenz + Harlow Flashcards
(15 cards)
Lorenz AO1
when was the research conducted
1952
what were the two conditions in lorenz’s study
incubator group and natural environment group (half in each)
findings from incubator group
lorenz was the first moving object they saw so the goslings followed him everywhere
findings from natural group
followed mother
definition of imprinting
bird species that are mobile from birth attach to and follow the first moving object they see
lorenz’s findings on the critical period
he suggested that there is a period of time in which imprinting must take place, if it doesn’t occur chicks dont attach to their mother
Lorenz’s findings on sexual imprinting
birds that imprinted on a human would later display courtship behaviour towards humans
AO3 (Lorenz)
+P: research support for imprinting
research has found that chicks exposed to simple shape combinations like a triangle with a moving rectangle in front (chicks imprinted)
Lorenz
+P: cannot extrapolate findings
can’t generalise findings from birds to humans. mammal attachment is more complex than birds
AO1 Harlow
when did harlow complete his study
1958
what animal did harlow test on
rhesus monkeys
what were the two wire model mothers
baby monkey cuddled the cloth covered mother in preference to the plain wire mother and sought comfort from the cloth mother when frightened regardless of which one dispensed milk
what happened to the monkeys that were deprived of a real mother
caused permanent and severe consequences in adulthood
they became more aggressive and less sociable (unskilled at mating)
discovered critical period was 90 days and that early deprivation was irreversible
AO3 Harlow
+P: real world application
helped social workers and clinical psychologists understand the reason behind the lack of bonding experience
practical value
AO3 Harlow
-P: can’t extrapolate
cannot genralise findings from monkeys to humans
the human brain and behaviour is more complex than monkeys
not appropriate
