What is imprinting?
Certain animals, many birds species, attach to their mother strongly; infant animal will follow mother. Lorenz called this imprinting
What was Lorenz (1935) procedure
- greylag goose eggs randomly divided: half hatched by Lorenz in an incubator, other half naturally hatched by mother
- later studies - varied time between hatching and when goslings first observed moving object
Findings
- hatched by Lorenz - followed him
- hatched by mother - followed mother
- put all in box and lifted box - goslings who imprinted on Lorenz found him and followed him
- Critical period of around 32 hours - if goslings didn’t imprint on a large moving object in this time then it loses ability to imprint
Conclusion
Imprinting is a strong evolutionary/biological feature of attachment in certain birds
AO3 Strength - point
Supportive research as studies found that animals attach to first object they see after birth
AO3 Strength - evidence
Guiton (1966) - leghorn chicks imprinted on gloves used to feed them in their first few weeks and makes tried to mate with the gloves
AO3 Limitation - point
Lorenz’s imprinting study has an issue with animal extrapolation
AO3 Limitation - evidence
Findings based off birds - problem generalizing from birds to human - different brains
