Chapater 5 Attachemnt Animal Studies Flashcards
What was Lorenz’s method?
- He took a clutch of gosling eggs that had been laid at the same time and then randomly split them in half
- one hand hatched normally and the other in an incubator with the first thing they saw being himself
What was Lorenz’s findings?
The goslings would follow him if he was the first thing they saw moving and the others would follow their mum if it was the first thing they saw
- also evidence that imprinting effected their late special behaviour
- Imprinting seemed to occur between 4 & 25 hours after hatching THE CRITICAL PERIOD
What was the conclusion of Lorenz’s study?
His findings support the theory that attachment formation may have a biological basis as the imprinting tends to be biological
-supports Bowlbys critical period theory for attachment + the continuity hypothesis
What did Guiton 166 find?
That mating perfectness can be unlearned
-e.g whooping cranes where endangered and people encourages them to migrate to areas they were extinct by imprinting the young bride on microlights
What was the aim and method of Harlow and Zimmermans study?
Aim- investigate whether a baby monkey is more likely to become attached to a fake mum that gives food,compared to a soft one that doesn’t
Method~ 16 new born moneys separated from their mums at birth & were reared in isolation and put into cages with the two type of mother
Results &conclusion of Zimmermans; Harlows study?
Monkeys spent longer clinging to the ‘soft mother’ and when scared ur ran to he soft mother
Conclusion - Attachment formation isn’t just the leaned association with food, comfort is also very important
What was Harlows isolation study 1965?
He did another experiment where she investigated the effects of raising newborn monkeys in isolation from other monkeys for 3,6,12 or 24 months
What was the finding of Harlows isolation study?
Found mine her were disturbed as adults and were highly fearful of other monkeys
-they had abnormal sexual behaviour and their extent of behaviour posit et correlated what the length they had been in isolation
Can we generalise the animals to humans ?
Yes
-especially monkeys as we share common ancestors and is have similar psychological processes
No
-difference in habitats + mental capacity e.g humans don’t imprint
What was Lorenz’s study investigating?
The attachment formation in goslings and whether an animal has an innate tendency to develop a strong bond with its mum in the first few hours of life -IMPRINTING
