What was the aim of Harlows study
Harlow wanted to see whether a baby could survive without love.
A01
What was the procedure of harlows study
- Had two types of mothers, a cloth and wire mother dispensed milk
- reared 16 monkeys
- rhesus monkeys were observed for 165 days and measurements were taken of how much time they spent with the mother
- observations were also made when the monkeys were frightened, but a loud noise or banging
AO1
What were the findings of Harlows study
- all monkeys spent more time with cloth mother than wire mother
- whens scared the monkeys sought comfort from cloth mother not wire mother
- this suggusts an attacment is formed with the person who comforts them and not feeds
AO1
What was the long term effects of Harlows study
Long term effects
- In a variation where some monkeys were only shown to teh wire mother, this happened
- socially abnormal (didn’t know how to act aound other monkeys)
- monkeys rocked back and forth
- mutilate themselves
- sexually abnormal (didn’t know how to mate)
- Harlow said teh ctrical peroid is 90 days and if an attachment was not formed then it would affect the monkeys neagtivuylu
A strength of Harlows research is that it has had real-world applications
research had a significant effect on understanding of attachment
- Howe et al said that it helped clinical psychologist and social workers understand the importance of bonding. Which allowed them to intervene in situations where they may have been a negative outcome
- Despite the harm caused to the monkeys, this research positive implications on how we view attachment
A03
A limitation of Harlows study is that it is unethical
- Some of the Rhesus monkey’s went through psychological trauma, and stress.
- Caused long term effects on the monkeys like being unable to form healthy relationships
- also monkeys quite similarly to humans so they may have suffered
- argue his research has had practical applications
A03
A limitation of Harlows evidence is that it is hard to generalise to humans
- Humans and animals have different cognitions and motivations, so it could be argued that attachment research on animals may not explain attachment in humans
- However research by Schaffer and Emerson highlighted how babies attached to the caregiver that responded to their cues and not the one who fed them
- This research suggests that human and animal attachment may not be so different, despite this it could be argued that attachment in humans may be more complex.
AO1
Outline the procedure Lorenz used
-Took some goslings eggs and divided them into 2
One was left with mother, whilst other group was left in incubator
–When eggs hatched one group saw Lorenz first the other saw their mother
-To test who they imprinted to Lorenz placed all the goslings in a box and lifted it to see who they came to
AO1
What were the findings of Lorenz’s study
- Incubator group followed Lorenz everywhere whereas as control group followed their mother
- Lorenz called this imprinting
- identified a critical period was a few hours
- Lorenz investigated imprinting and adult mate preferences and found that birds that imprinted on humans were tried to mate with humans
AO3
There is supporting research for Lorenz
- strength: there is supporting is evidence for the concept of imprinting
- Evidence: Regoilin et vallorigara (1995), chicks were exposed to simple shape combinations that moved like a triangle with a rectangle in front
- a range of shapes were then shown to the chicks but they followed the orignal the closest
- another study by Guilton found that when chicks were shown a yellow glove they imprinted and followed.
- Also found chicks tried to mate with glove
- this supports the view that young animals are born with an innate mechanism to imprint on a moving object present in the critical period during development
AO3
A limitation of Lorenz’s research is
-hard to generalise data on birds to humans
-mamilian attachment system is different for example for mamals it is a two way process, as not only does the child bond to the mother, but the mother bonds to the child
-therefore it may not be approiate to generalise the fndings in terms of attachment, however it could be used in teh scence that humans attach to other things.
-Seeback found that humans show baby duck syndrome, which is when human attach to first operating system and reject other.
Therefore imprinting could be a useful exlanation of human attachment with inaminate objects that mean things to them
AO3
A limitation of Lorenz is that there is conflicting evidence
- For years it was thought that imprinting was an irreversible process, that was permanently stamped onto the nervous system
- However, it is now thought that imprinting mechanism and forcible (Hoffman)
- Guiton also found that after spending a while with their won species they began to engage with normal sexual behaviour with other chickens
- This shows imprinting may not be different from other types pf learning. As learning can take place rapidly with conscious thought but can also be reversed
SO1
Who came up with the learning theory of attachment
- Dollard and Miller
- this is known as cupboard love as it places emphasis on the attachment figure as being the provider of food
- Learning theory of attachment proposes that all behaviour is learnt rather than an innate biological behaviour
- They also believe children are born blank slates.
AO1
Outline the classical conditioning approach to attachment
- Classical conditioning of attachment involves the child associating two stimuli together
- The unconditional stimulus of food is associated with the unconditional response of pleasure
- the caregiver starts as the neutral stimulus however after time they are become associated with the food
- So when the baby expects the caregiver to have food with them when they see them (so the caregiver is the conditioned stimulus)
- Eventually, the child associate the conditioned stimulus (caregiver) with the conditioned response of pleasure
- attachment is formed
Outline the operant conditioning explanation of attachment
- Learning from consequences
- In attachment babies cry which leads to a response from the caregiver like food or comfort
- this reinforces the behaviour of crying
- so when the baby needs something it will cry this is an example of positive reinforcement
- For the caregiver, they experience negative reinforcement because the crying (unpleasant behaviour) stops, so providing food, comfort etc when a child is crying is reinforced
- this is how attachment happens
AO1
What is the idea of attachment being a secondary drive
-Sears et al suggested the idea of drive reduction theory.
-Hunger is a primary drive, it is innate etc.
The secondary drive will help you receive your primary drive, meaning attachment.
-So a baby will form an attachment in order to satisfy their primary drive.
AO3
Learning theory has conflicting evidence from animal studies
Harlow and Harlow
- they found that when monkeys were observed they spent 18 hours a day with cloth mother the mother that provided them with warmth
- therefore this illustrates how learning approach of attachment may not explain why the rhésus monkeys attached to the cloth mother
AO3
Conflciting evidence from human studies
Schaffer and Emerson
They found that the caregiver that infants attached to was the one that responded to their cues
-65% this was the mother
-moreover Tronick studied the efe tribe Zaire. Infants breastfed by different mothers but slept with own mother at night. At 6 months child showed primary attachment to mother.
-this highlights how babies don’t attach to those who feed them further highlighting …
AO3
Learning theory has some explanatory power
- Can explain how some elements of conditioning may be involved in attachment
- unlikely that association plays a role but conditioning does
- for example, a baby may associate feeling warm and comfortable with a particular adult
- this may influence babies choice in attachment
- therefore learning theory may be useful
- Cp: stills presents attachment as a passive process not active
AO3
An alternative explanation for learning theory of attachment is
SLT- Hay and Vespo
- SLT does not reduce attachment down to food and pleasure,
- for example, they believe that love can be modelled, by things like hugging.
- This theory can help explain things like reciprocity and international synchrony.
- However, SLt finds it hard to explain how these are important, or why this thing like reciprocity and international synchrony are found among humans and animals.
- Therefore it could be argued that social learning theory despite it flaws is a good explanation of attachment
AO1
What is bowlby monotropic theory based on
- Influenced by the work of Lorenz and Harlow
- belives the behaviour of attachment evolved because of the need for survival
- an infant who was not attached was more likely to die
- important that attachment is two ways process as parents attach to infants to make sure they are cared for and survive
- parents who look after offspring are more likely to have subsequent generations
- based on the evolutionary approach
AO1
What are the stages of Bowlby’s monotropic theory
Monotropy: proposed infants have 1 special emotional bond (which is the primary attachment) usually it is the mother
- Infants also form secondary attachments which act as a safety net which is important for the development
- law continuity:
- law of accumulated separation
Social releases: social releases such as smiling and having baby face, or cooing. This is used to activate adult social interaction so this makes the baby attach to adult. Both baby and adult are hard wired to becomme attached
Crtical period: the crtical period of attachment is between 30 months. Infants who don’t form attachments may find it harder to form attachments in the future
Internal working model: a consequence of not forming an attachment during the critcial period, is an effect on the internal working mdoel. A long term consequence is that it acts as template for all future relationships as it generates expectations about what is an intimate loving realtionship
