Attachment key studies Flashcards
Lorenz (?)
1935
Aim of Lorenz
to see the effects of imprinting and if animals bond with the first thing they see
Findings of Lorenz
goslings divided themselves into the group that hatched infront of mother and lorenz and showed no recongition of mother
imprinting can only happen if it happens within critical period (few hours)
Procedure of Lorenz
took greylag geese eggs and divided into two groups
one group (control) left with mother and hatched normally and other placed in an incubator.
when incubator eggs hatched first thing they saw was lorenz and they started following him around
lorenz marked the two groups to distinguish them and placed them together when lorenz and mother was present.
Long lasting effects
- imprinting is irreversible and long lasting
- one of the geese that imprinted on him used to sleep in his bed every night
- had an effect on later mate prefrences, sexual imprinting, where they will choose to mate with what they imprinted on
AO3 - research support
Guiton (1966) demonstrated that chicks exposed to yellow rubber gloves imprinted on them.
supports idea that young animals not born with predisposition to imprint on a specific type of object but any moving thing present in critical period
also found tried to mate with rubber glove, showing early imprinting linked to later mate prefrences
AO3 - critiscms of imprinting
idea that imprinting is irreversible and permantley stamped on nervous system is no longer accepted
e.g Guiton found that he could reverse imprinting in chickens that initially tried to mate with rubber gloves
he found that later spending time with their own species, able to engage in normal sexual behaviour
suggests imprinting may not be as perm as previously suggested
Harlow (?)
1959
Aim of Harlow
study effects of maternal deprivation and what was most important in mother-infant bond
Procedure Harlow
created two wire surrogate mothers - one wrapped in cloth and one plain with food
8 infant rhesus monkeys seperated from mothers and studied for 165 days
measured how long monkeys spent on each mother and which mother they went to in response of fear to a mechanical bear
Harlow’s findings
all spent most time on cloth mother - some 23hrs a day
when frightened clung to cloth mother and when playing with new object kept one foot on cloth (reassurance)
Conclusion of Harlow
suggests infants do not develop an attachment to the person that feeds them but the person offering contact comfort
Long lasting effects
continued to study monkeys as they grew up
found critical period of 90 days
developed abnormal social behaviour
maternally deprived = more aggressive, less sociable and bred less
neglected their children or attacked them
AO3 - generalisation to humans
humans decisions are governed by conscious thought however still has important applications
supported by schaffer and Emerson who suggest babies form attachments from those who feed them
shows importance of contact comfort and the impact early attachments have on adult life
AO3 - ethics
the study created lasting emotional harm as the monkeys found it difficult to form relationships with their peers
OTOH, can be justified through the significant effect it has had on our understanding of the processes of attachment and how the research has offered better care for infants
it could be argued the benefits outweigh the costs
AO3 - real world applications for social workers
helped social workers understand risk factors for child abuse and neglect and can then intervene to prevent it
also important in the care of captive monkeys - now understand the importance of proper attachment figures for baby monkeys in zoos
Ainsworth strange situation (?)
1978
Aim of Ainsworth
measure the security of attachment a child displays to a caregiver
Procedure of Ainsworth
controlled observation, room with a two-way mirror with psychologists observing behaviour
judged: proximity seeking, exploration and secure-base behaviour, stranger and seperation anxiety and response to reunion
- child encouraged to explore
- stranger comes in and tries to interact
- caregiver leaves
- caregiver returns and stranger leaves
- caregiver leaves child alone
- stranger returns
- caregiver returns and reunited
Findings of ainsworth
identified three attachment types
- secure = moderate anxiety, happily explore but go back to caregiver, accept comfort in reunion stage
- insecure avoidant = explore freely do not seek proximity, indifferent reaction sep to anxiety or reunion and little stranger anxiety
- insecure resistant = high proximity, stranger and sep anxiety, resist comfort when reunited
