- 1Lorenz's Research (1935)- Took a clutch of gosling eggs and split them into 2 groups (half were left with the mother)
- Incubated eggs hatched and the first moving thing they saw (Lorenz) they became attached to
- IMPRINTING - 2Lorenz (1935)- One group followed the mother and the other Lorenz (this group showed no recognition of the mother)
- Imprinting occurs during the critical period
- 1952 - imprinting is irreversible and had a later effect on mate choice (sexual imprinting) and will choose to mate to mate with the same kind they imprinted on - 3EvaluationResearch support
> Guiton (1966) chicks were exposed to yellow rubber gloves for feeding them and became imprinted on them
> Imprinting is not specific
> Early imprinting is linked to reproductive behaviour - 4EvaluationCriticisms of Imprinting
> Dispute over the meaning
> An encounter with an appropriate object leads to the image of that object being irreversibly stamped into the nervous system
> Now understood to be reversible - 5Harlow's Research (1959)- 2 mothers were created (wire and cloth) with different heads
- Cloth mother with milk and wire mother with milk (4, 4)
- Amount of time spent with each was recorded
- Were frightened by a mechanical teddy - responses were also recorded - 6Harlow (1959)- All 8 monkeys spent most of the time with the cloth mother even if it didn't have milk
- Short periods of time were spent with the wire mother only for food
- When frightened they spent time with the cloth mother
- Became socially and sexually abnormal - 7EvaluationEthics
> Harlow's study could not be done with humans
> Created emotional harm as the monkeys found it difficult to form attachments with others - 8EvaluationGeneralising animal behaviour to humans
> Humans differ in important ways as behaviour is governed by conscious decisions
> Harlow's research is supported by Schaffer and Emerson's findings
