Lorenz's Geese Study AO1

Question 1

What is imprinting?

Answer 1

when a bird attaches to and follows the first moving object they see

Question 2

Describe the procedure of Lorenz’s study.

Answer 2

• there were 2 groups of geese
• one (experimental group) hatched in an incubator infront of Lorenz
• one (control group) hatched in a normal setting infront of their mother

Question 3

Explain the results of the findings of Lorenz’ study.

Answer 3

• experimental group followed Lorenz
• control group followed mother
• this occured even when the baby geese were mxied up
• Lorenz suggested this was due to imprinting and this is a process that is irreversible and long lasting and must occur during the critical period
• imprinting could effect who they mate with in the future (will chose the same mate as what they imprinted on)

Question 4

How long is the critical period?

according to Lorenz

Answer 4

a few hours after hatching
