animal studies

Question 1

outline lorenz’ study

Answer 1

• took a large clutch of eggs from goose + kept them until they hatched in an incubator
• once hatched, goslings followed first object they saw (Lorenz) between their critical period (13-16 hours)- saw him as mother
• irreversibly imprinted as study operated during critical period
• goslings innately follow moving objects after hatching- adaptive since they have mobility unlike human infants

Question 2

outline harlow’s study with cages

Answer 2

M: monkeys placed in cages with cloth mother (comfort) and wire mother (food); monkey scared + recorded which mother they ran to
R: ran to cloth mother to seek safety over food for survival

Question 3

outline harlow’s study with experiment room

Answer 3

R: monkey felt most comfortable to explore room with cloth mother

Question 4

what happened to the monkeys later in life after being separated from their parents

Answer 4

developed dysfunctional social behaviours (timid, unable to mate)

Question 5

evaluate the animal studies of attachment

Answer 5

A: humans and monkeys are similar: Green found all mammals have same brains structure- only difference is size and number of connections
C: results can’t be generalised to humans: critical and sensitive period is different and humans are more complex
C: unethical: experiments harm animals and can cause dysfunctional behaviours in adult life (timid, difficulty mating)
