- ANIMAL STUDIES
- LORENZ
- Aim
- Whether attachment was innate in animals
- Method
- Clutch of gosling eggs and divided into 2 groups
- Left with natural mother
- Incubator
- When hatched first moving thing they saw was Lorenz
- When together they spilt into the groups : natural mother and Lorenz
- Clutch of gosling eggs and divided into 2 groups
- Findings
- Critical period of 12-17 hours
- Imprint on first moving object they see
- Guiton 1966
- Chicks would imprint on yellow rubber gloves
- Mated with yellow rubber gloves when older
- Chicks would imprint on yellow rubber gloves
- Guiton 1966
- important for long and short term
- ST - protection and being fed
- LT - mating
- A03
- Generalisability to humans
- Mammalian attachment is quite different to birds
- Not appropriate to generalise to humans
- Mammalian attachment is quite different to birds
- Some of Lorenz's observations have been questioned
- The impact of imprinting on mating behaviour is not as permanent as Lorenz belived
- Generalisability to humans
- Aim
- Harlow 1958 - The Nature of love
- Aim
- To test cupboard love to attachment
- Method
- Baby sized cloth covered surrogate and wire surrogate which dispensed milk
- 16 baby Macaques
- 4 in each 4 conditions
- in 2 conditions - both cloth and wire
- In 1 wire produced milk and in the other cloth produced milk
- 2 remaining conditions - single surrogate, wire or cloth
- in 2 conditions - both cloth and wire
- 4 in each 4 conditions
- Eating patterns were compared
- Stress test
- Noisy toy was presented to each monkey
- Apparatus - test tendency to explore
- Findings
- Eating pattern did not vary
- Monkeys with wire had watery face - sign of stress
- Noisy toy made a loud noise they would retreat to their mothers
- Chose the cloth over the wire even if it didn't produce milk
- When given apparartus the monkey with the cloth explored more
- A03
- Theoretical value
- Profound effect on psychologist understanding human mother-infant attachment
- Does not form by being fed but comfort
- Practical value
- Helped social workers understand risk factors in child neglect and abuse
- Ethical issues
- Monkeys suffered greatly - suffering was quite human like
- Theoretical value
- Aim
- LORENZ
