Attachment Flashcards
Outline Lorenz’s geese imprinting study
- Randomly divided large clutch of goose eggs
- One half were hatched with the mother goose in their natural environment (CONTROL GROUP)
- The other half hatched in an incubator where the first moving object they saw was Lorenz
- Mixed all goslings together to see who they would follow
- Incubator group followed Lorenz, control group followed their mother
- Lorenz identified a CRITICAL PERIOD in which IMPRINTING needs to take place, e.g. few hours after hatching
- If imprinting did not occur within that time, chicks did not attach themselves to the mother figure
Outline Harlow’s rhesus monkey attachment study
- 16 rhesus monkeys reared with two wire model “mothers”
- CONDITION 1 - milk dispensed by plain wire “mother”
- CONDITION 2 - milk dispensed by cloth covered wire “mother”
- Monkeys’ preferences were measured
- To measure attachment-like behaviour, Harlow observed how the monkeys reacted when placed in frightening situations, e.g. adding a noisy mechanical teddy bear to the environment
- Baby monkeys cuddled the cloth covered mother in preference to the plain wire mother, regardless of which one they took milk from
- This suggests that contact comfort was of more importance than food when it came to attachment behaviour
- Harlow continued to study the monkeys who’d been deprived of their real mother into adulthood
- As adults, the monkey’s who’d been deprived of their real mothers suffered severe consequences - they were more aggressive, less sociable and less skilled in mating than other monkeys
Regolin and Vallortigara have research support for Lorenz’s concept of imprinting. How is this a strength?
- Regolin and Vallortigara exposed chicks to simple shape-combinations that moved
- When shown a range of moving shapes, the chicks followed these in preference to other shapes
- This suggests that young animals are born with an innate mechanism to imprint on a moving object
How is trying to generalise from birds to humans a weakness of animal studies of attachment?
- The mammalian attachment system is quite different from imprinting in birds
- For example, mammalian mothers show more emotional attachment to their young
- This means that it may be inappropriate to generalise Lorenz’s ideas about imprinting to humans
Lorenz’s imprinting theory has applications to human behaviour. How is this a strength of animal studies into attachment?
- The concept of imprinting can explain some human behaviour
- For example, “baby duck syndrome”, in which computer users become attached to their first operating system
- This means that imprinting is a meaningful process in humans as well as birds
Harlow’s research has real-world value. How is this a strength of animal studies of attachment?
- According to Howe, it’s helped social workers understand risk factors in child abuse and thus intervene to prevent it
- We also now understand the importance of attachment figures for baby monkeys in zoos and breeding programmes
- This means that Harlow’s research has benefitted both animals and humans
How is generalising from monkeys to humans a weakness of animal studies of attachment?
- Monkeys are clearly more similar to humans than Lorenz’s geese, and all mammals share some similarities in their attachment systems
- HOWEVER, they are not human and in some ways, the human mind and behaviour are much more complex
- This suggests that it may be inappropriate to generalise Harlow’s findings to humans
Harlow’s research has ethical issues. How is this a weakness of animal studies of attachment?
- Harlow’s procedures caused severe long-term distress to his monkey participants, though the research led to useful applications
- HOWEVER, his findings and conclusions have important theoretical and practical applications
- This suggests that, in spite of its benefits, Harlow’s research shouldn’t have been carried out
Describe learning theory as an explanation for attachment
Describe the importance of food in the learning theory of attachment
- Sometimes called “cupboard love” explanation because it emphasises the importance of food in attachment formation
- Children learn to love whoever feeds them
Outline the role of classical conditioning in attachment
- Classical conditioning involves learning to associate two stimuli
- Food (UCS) leads to feelings of pleasure (UCR)
- Mother starts as a NS but when she provides food over time, she becomes associated with food so becomes a CS
- Once conditioning has taken place, the sight of the mother produces a CR of pleasure. According to learning theory, the conditioned pleasure is the basis of love
- Now an attachment has formed and the mother becomes an attachment figure
Outline the role of operant conditioning in attachment
- Operant conditioning explains when babies cry for comfort (an important building for attachment)
- Crying leads to a response from the caregiver (e.g. feeding)
- As long as the caregiver provides the correct response, crying is reinforced because it produces a pleasurable consequence
Describe negative reinforcement in attachment
- At the same time as the baby is reinforced for crying, the caregiver receives negative reinforcement because the crying stops
- Negative reinforcement is escaping from something unpleasant
- This interplay of positive/negative reinforcement strengthens an attachment
Outline hunger drive reduction in attachment
- Hunger is a PRIMARY DRIVE, so we are motivated to eat to reduce the hunger drive
- Attachment is a SECONDARY DRIVE learned by association between the caregiver and the satisfaction of a primary drive
- Sears et al. suggested as caregivers provide food, the primary drive of hunger becomes generalised to them
There is counter evidence to learning theory from animal studies. How is this a weakness of learning theory?
- Lorenz’s geese imprinted on the first moving object they saw
- Harlow’s monkeys attached to a soft surrogate in preference to the wire one with milk
- In both these animal studies, imprinting/attachment did not develop as a result of feeding
- This shows that factors other than feeding are important in attachment formation
There is counter evidence to learning theory from human studies. How is this a weakness of learning theory?
- Schaffer and Emerson showed that for many babies, their main attachment was NOT to the person who fed them
- Also, Isabella et al. found that interactional synchrony (unrelated to feeding) predicted attachment quality
- This also suggests that other factors are more important in attachment than feeding
Some elements of conditioning could still be involved in learning theory. How is this a strength of learning theory?
- It seems unlikely that association with food is central to attachment. HOWEVER, conditioning may still play a role in attachment
- For example, a baby’s choice of primary attachment figure may be determined by the fact that a caregiver becomes associated with warmth and comfort
- This means that conditioning could still be important in the choice of attachment figures, though not in the process of attachment formation
Learning theory may be inappropriate in explaining any aspect of attachment. How is this a weakness of learning theory?
- Learning theory ignores the fact that babies take a very active role in the interactions that produce attachment
- For example, they initiate interactions, according to Feldman and Eidelman
- This suggests that learning theory may be inappropriate in explaining any aspect of attachment
Learning theory can be developed into social learning theory. How is this a strength of learning theory?
- Hay and Vespo suggest that parents teach their children to love them by modelling attachment behaviour, e.g. hugging and kissing
- Parents also reward babies with approval when they display their own attachment behaviour (“that’s a lovely smile” etc.)
- This means that social learning theory can provide better explanations, including explaining the active role taken by babies in attachment development
Outline Bowlby’s monotropic theory of attachment
- Bowlby’s theory is described as monotropic because of the emphasis on the child’s attachment to one caregiver
- This attachment is different from others and more important
- Bowlby believed that the more time a baby spent with their primary caregiver, the better, due to the LAWS OF CONTINUITY and ACCUMULATED SEPARATION
Define the Law of Continuity
The more constant a child’s care, the better the quality of attachment
Define the Law of Accumulated Separation
The effects of every separation add up
Describe Bowlby’s social releasers
- Bowlby suggested that babies are born with a set of innate “cute” behaviours (e.g. smiling, cooing, gripping) that encourage attention from adults
- The purpose of these social releasers is to activate adult social interaction (i.e. make an adult attach to the baby)
- Bowlby recognised that attachment is a RECIPROCAL SYSTEM
Outline Bowlby’s critical period
- Critical period of about 2 years when the infant attachment system is active (viewed more of a SENSITIVE PERIOD)
- A child is maximally sensitive at 6 months and this may extend up to the age of 2 years. If an attachment has not formed in this time, a child will find it much harder to form one later
