6 saw mother after hatching
6 saw Lorenz after hatching
What did lorenz find from the first procedure?
-the goslings followed whoever they saw straight after hatching (imprinting)
what was the second procedure to Lorenz study?
.he put all the goslings in a box
what were the findings from the second procedure?

.first bond affect mating preferences (sexual imprinting) -the goslings displayed mating behaviours on who they imprinted on
What was a strength to Lorenz study?
-futher study backs up (chicks imprinted on a rubber glove)
What was a negative to Lorenz study?
-cannot be generalised (birds may not be the same as humans)
- guiton showed imprinting wasnt permanent as chicks mating preferences changed when introduced to other chicks
What was the aim of Harlows study?
To investigate wether the first attachment is based off who offers food or comfort contact
What was the sample of harlows study?
16 infant monkeys
What was the procedure of harlows study?
-infant monkeys put through several scenarios
-experience each scenario in room with both surrogate mothers

-ethical issues (infant monkeys were killed after study) (put through harm during study)
-cannot be generalised (monkeys not exactly same as humans)
