Lorenz - Animal Studies Of Attachment

Question 1

What are the two animal studies of attachment?

Answer 1

Lorenz and Harlow

Question 2

What was Lorenz aim and method?

Answer 2

Lorenz investigated the effects of imprinting on goslings using a field exp

Question 3

What was Lorenz procedure?

Answer 3

• lorenz randomly divided goose eggs so that half of the eggs hatched with mother goose in nat env and other half in incubator where first moving object they saw was lorenz
• once the eggs had hatched, both groups were mixed up and lorenz obsv who they followed
• lorenz recorded imprinting bhv of goslings
• he varied the time bw birth and seeing a moving object to measure critical period of imprinting

Question 4

What was Lorenz findings?

Answer 4

• the incubator group who saw lorenz first imprinted and followed lorenz whereas as group who saw mother first imprinted and followed her
• lorenz identified critical period of 12-17 hours after hatching to imprint, if they do not then they will not att themselves to a mother figure at all
• goslings who imprinted on humans, attempted to mate with humans as adult birds

Question 5

What did Lorenz conclude?

Answer 5

Goslings imprint on first moving object that they see and there is a specific critical period of 12-17 hours in which imprinting needs to take place otherwise they will not attach at all

What are the three AO3 PEELS to evaluate Lorenz animal studies of attachment?

Answer 6

• prac apps
• animal bias
• researcher bias
