Animal studies of attachment

Question 1

Lorenz 1952 Procedure (imprinting)

Answer 1

Randomly divided a large clutch of goose eggs
Half hatched naturally with mother
Half hatched in incubator with Lorenz being first seen

Question 2

Lorenz 1952 findings

Answer 2

Incubator group followed Lorenz everywhere
CG followed mother
When both groups were mixed up, both separated to their original group
Imprinting-birds that are mobile from birth attach and follow the first moving thing they see at birth
Identified a critical period
Without imprinting in crit period, chicks didnt attach to mum figure

Question 3

Lorenz sexual imprinting

Answer 3

Birds that imprinted on humans displayed courtship behaviours to humans

Question 4

LORENZ EVAL+: Research support

Answer 4

Regolin and Vallortigara (1995) Chicks followed an original moving shape even with other combinations moving in front of it
Born with innate imprinting mechanism which is present during the critical window of development

Question 5

LORENZ EVAL-: Generalisability to humans

Answer 5

Mammalian and additionally human attachment much more complex, for example its a two way process

Question 6

Harlow 1958 procedure

Answer 6

Tested contact comfort
Reared 16 monkeys with 2 wire model mothers
1 mother was mesh and milk, other cloth
