Animal studies + E Flashcards
What did Lorenz (1935) do?
Set up an experiment where half of the geese eggs hatched inform of their mother and the other half in front of him
What animal did lorenz use?
Goose
What were Lorenz findings?
The incubator group followed Lorenz and the other group followed the mother goose. Who they had imprinted on.
What was the critical period that Lorenz identified?
In the first few hours when the ducks are born, they attach to the first moving thing that they see
What happened if there is no imprinting?
The chick will not develop a mother figure
What did Lorenz find about sexual imprinting?
The birds displayed sexual behaviours towards the species that they imprinted on.
What is a strength of Lorenz’s study?
RE
Lucici and Giorgo (1995)
A similar study using objects and had similar findings
What is the weakness of Lorenz’s study?
G
Lacks generalisability as humans and animals are very different.
What did Harlow (1958)
Tested monkeys.
reared monkeys on a wire and cloth mother that dispensed milk.
What was Lorenz testing?
Whether the food was an important factor in the development of attachment
What did Harlow find?
When frightened no matter what mother that they were reared on they prefer the cloth mother
This proved that comfort was more important than food in the development of attachment.
What were the long term consequences of the research on monkeys
The maternally deprived monkeys did not develop normal social behaviours
some who became parents neglected became aggressive and some even killed their young
What are the real-world applications of Harlows research
- Helped social workers and clinical psychologists show that lack of bonding experience is a risk factor.
- understand attachment behaviour in monkeys
P: lacks generalisability to humans
E: Monkeys are more similar to humans than birds. But human att. Is more complex than monkeys
E: TMT It may not be appropriate to generalise hallows findings to humans
P: Ethical issues
Hallows research caused severe & long term distress to the monkeys .
But his research is theoretically and practically useful
