Attachment Flashcards
What is infancy?
Infancy is the period in a childs life before speech
What is reciprocity in infants?
research in the 1970s showed that infants co-ordinate actions with caregivers for example they move in rhythm like in conversation
- Brazelton (1979) - the rhythm is important as it enables the carrier to anticipate behaviour and respond this builds up attachment
Describe the procedure of Meltoff and Moore experiment?
1977
- adult model displays are of three facial expressions and hand gestures
- dummy placed in mouth when gestuire displayed to prevent response
- dummy removed and childs expression filmed
- infant copied
- shown to an observer to judge behaviour, they did not know the behaviour that was being imitated
- all scores greater than 9.2
1983
- repeated with 3 day old babies this ruled out the idea that imitation learned
is the imitation in the infants real or pseudo-imitation?
Meltzoff and Moore thought that the imitation was intentional whereas John Piaget believed that the response was training
- training - infant repeats behaviour that was rewarded (with a smile) therefore operant conditioning and pseudo - imitation
- intentional - Murry and Trevarthen - they used 2 month olds which interacted with there mother on a webcam in real time then in not real time, when the mother did not interact and respond the baby became distressed this provbed that they were an active part in the relationship
what were the problems with Meltzoff and Moore study
- constant moving mouths and expressions therefore difficult to distinguished.
This was fixed by filming the babies and using an outside observer - failure to replicate - the Koepke et al was less carefully controlled
what were the problems with the Murry and Thervarthen study?
in another study Marian et al, the infants did not react
What proves that the infants response is intentional?
Abravanel and DeYoung - tested 5 week olds - little response to objects that showed tongue and mouth movements therefore specific response to humans
What does interacting do to the baby?
Isabella et al - strong infant to caregiver relationship the greater the interactional synchrony
Heiman - infants that had more imitation had a better relationship
Whats the value of the research in the Meltzoff and Moore study?
It proved
- connection between what the infant sees and imitation associate their own acts and underlying mental states
- project there own experiences onto others performing similar acts
- acquire an understanding of what people are feeling and thinking
Describe Lorenz procedure
- took some gosling eggs and divided them into 2 groups
- one group with natural mother other in incubator
- when the incubator eggs hatched the first moving object they saw was Lorenz
- to test the imprinting Lorenz marked the chicks then mixed them up
Describe Lorenz findings
- Goslings divided themselves up
- incubator chicks flowed Lorenz
- imprinting restricted to definite period of time called the critical period
- some animals do not imprint on humans
What were the long lasting effects of Lorenz study?
- irreversible
- long lasting
- preference on later mate, they chose to mate with object on which they imprinted
What was Harlow’s hypothesis?
a mothers love is not based on feeding
What was Harlow’s Procedure?
- created 2 wire mothers with different heads
- one mother was wrapped in cloth
- 8 monkeys studied for 165 days
- 4 monkeys had milk bottle on cloth mother and the other 4 on wire mother
- measurements made to how long spent with each and responses made when frightened
What was Harlow’s findings?
- all 8 spent most time with cloth mother even when it did not have the feeding bottle
- those who fed on wire only spent small amount of time there
- when frightened they clung to cloth
- when playing with new toy they had one paw on cloth mother
What was the long lasting effects of Harlow’s study?
- they were socially and sexually abnormal when older and did not play with other monkeys or cradle their offspring
- after 3 months they could recover but after 6 months they could not
- critical period
What was the research supporting imprinting?
Guiton (1966) - Leghorn chicks exposed to yellow gloves and imprinted on them, later they tried to mate with the yellow gloves
What was the criticism of imprinting?
Guiton found it could be reversed
What was the confounding variable in Harlow’s study?
2 different heads therefore it varied systematically with the IV
What was the problem with generalising animal studies to humans?
Humans differ to animals as we make more conscious decisions but Schauffer and Emerson supported that infants are not attached to people who feed them
