goose eggs
What were the conditions in Lorenz (1952)’s study?
Half the eggs were hatched with the mother goose in their natural environment and the other half hatched in an incubator where the first moving object they saw was Lorenz
In Lorenz (1952)’s study, what was the first moving object that the eggs hatched in an incubator saw?
Lorenz
What did Lorenz (1952) find that the incubator group did in his study?
Followed Lorenz everywhere
What did Lorenz (1952) find that the control group did in his study?
Followed the mother
What happened when Lorenz (1952) mixed the two groups up in his study?
The control group followed the mother and the experimental group followed Lorenz
Which group was the control group in Lorenz’ study?
The group hatched in the presence of the mother
Which group was the experimental group in Lorenz’ study?
The group hatched in the incubator
What was the phenomenon that Lorenz (1952) researched called?
Imprinting
What is imprinting in terms of bird species that are mobile from birth?
They attach to and follow the first moving object they see
Lorenz identified a ________ ______ in which imprinting needs to take place
critical period
When is the critical period?
Depending on the species this can be as brief as a few hours after hatching (or birth)
What did Lorenz find happened if imprinting did not occur within the critical period?
Chicks did not attach themselves to a mother figure
Lorenz also investigated the relationship between imprinting and what kind of preferences?
Adult mate preferences
Lorenz (1952) observed that birds that imprinted on a human would often later display…
courtship behaviour towards humans

reared in the reptile house of a zoo where the first moving objects the peacock saw after hatching were giant tortoises

giant tortoises
In Lorenz (1952)’s peacock case study, as an adult this bird would only direct courtship behaviour towards what?
Giant tortoises
Why did the peacock in Lorenz (1952)’s case study only direct courtship towards giant tortoises?
They were the first moving objects the peacock saw after hatching
What did Lorenz (1952) conclude about the peacock in his case study?
It had undergone sexual imprinting
Who carried out the most important animal research in terms of informing our understanding of attachment?
Harlow
Which animal did Harlow work with?
Rhesus monkeys
Which are more similar to birds, Lorenz’s birds or Harlow’s rhesus monkeys?
Harlow’s rhesus monkeys
