- Imprinting
- Lorenz's Animal Research
- Evaluation
- Generalis-ability to humans
- Difficult to generalise findings on birds to humans. Mammalian attachment is different from that in birds
- Mammalian mothers show more emotional attachment to young than do birds.
- Mammals may be able to form attachments at any time, albeit less easily than in infancy.
- Meaning it isn't appropiate to generalise any of Lorenz's ideas to humans
- Some of Lorenz's observations have been questioned
- The idea that imprinting has a permanent effect on mating behaviour.
- Guiton et al (1966) found that chickens imprinted on yellow washing up gloves would try to mate with them as adults
- However, they eventually learned to prefer mating with other chickens, mating behaviour is not as permanent as Lorenz suggested
- Generalis-ability to humans
- Sexual Imprinting
- Lorenz also investigated the relationship between imprinting and adult preferences
- Birds that imprinted on a human would often display courtship behaviour towards humans
- (1952) Peacock hatched - first thing saw was giant tortoises,. As an adult only direct courtship towards other giant tortoises
- Concluded that the bird had undergone sexual imprinting
- Evaluation
- Lorenz first observed the phenomenon of imprinting when he was a child
- A neighbour had given him a newly hatched duckling that followed him around

- Findings
- Incubator group followed Lorenz everywhere

- Evaluation
- Control group (hatched in natural environment) followed mother
- When both groups were mixed the control group continued to follow their mother and the incubator group followed Lorenz
- This is known as imprinting, attach to the first moving thing they see.
- Lorenz identified a critical period in which imprinting needs to take place.
- Depending on the species this can be as brief as a few hours after hatching.
- If it doesn't occur within that time Lorenz found they do not attach themselves to a mother figure
- Depending on the species this can be as brief as a few hours after hatching.
