What is an attachment
A strong emotional bond between two people
A two way process that continues over time, and is shown through a desire to maintain proximity
Who did the two animal studies of attachment
Lorenz and Harlow
What was the aim of lorenz’s study
To investigate mother- infant attachment in birds
What was the procedure of Lorenz’s study
Lab experiment
Independent groups design:
- Control group- half eggs left with mother goose in natural environment
- Experimental group- half eggs placed in incubator and first moving object they saw was Lorenz
marked the two groups to be able to distinguish them, and then placed them all together, with the mother and Lorenz present
Lorenz also followed the geese into adult hood to test the long term affects
What were the findings of Lorenz’s study
Imprinting- The experimental group who had seen lorenz first, followed him closely. The control group, followed their mother.
After lorenz put them all together, he foudn that the two groups went to their respective mothers
Long lasting effects- Found the process to be irreversible and long lasting. It also had an effect on mate preferences later in life
Critical period- Lorenz identified a critical period of 48hours, where imprinting needed to happen. If it didnt occur within this time, Lorenz found that they didnt attach to a mother figure
What was the conclusion from Lorenz’s study
Highlighted the importance of imprinting on animals and the evolutionary advantage of attachment, as the chicks followed their mother, which makes them more likely to be safe from predators, to be fed, and to learn how to find food.
Also showed there is a critical period for attachment to form in, and if it doesnt in this time, it will make it alot harder to form a new attachment later on
What are the points of evaluation for Lorenz’s study
Research support for imprinting and critical period- Guiton
Contradictory evidence
Ethical issues
What is research support for imprinting and critical period (evaluation of Lorenz’s study)
P- Studies support Lorenz’s research
E- Guiton
E- exposed chicks to yellow rubber gloves when feeding them during the first few weeks after birth
E- found tat they became imprinted on the glove, supports view that young animals imprint on any moving object that is there during the critical period
R- suggests a critical period where attachments have to be formed, otherwise it will lead to long-term consequences.
What is contradictory evidence (evaluation of Lorenz’s study)
P- Many psychologists dispute the view that imprinting is irreversible
E- Guiton
E- When chickens grew up and spent time with their own species, they engaged in normal mating behaviour
E- Shows imprinting can be reversed after the critical period
R- Suggests imprinting isnt as permanent as lorenz thought
What was the aim of Harlows study
Wanted to demonstrate that attachment wasnt based on the feeding bond between mother and infant
What was the procedure of Harlows study
Lab experiment
Independent groups:
- Condition one- cloth mother provided milk, and wire monkey didnt
- Condition two- wire monkey provided milk, cloth monkey didnt
Each group had 4 monkeys, and they were studied for 165 days.
Harlow measured how much time the monkeys spent with the two different mothers, and how they reacted when frightened
He also followed them into adulthood to record the long term effects
What were the findings of Harlows study
Baby monkeys spent most time with cloth covered mother, even if it didnt have the bottle. Those who fed from the wire mother, fed, then returned quickly to the cloth mother. When frightened, they all ran to the cloth monkey, and treated it as a secure base
Critical period- Found that a mother figure ahd ot be introduced within 90 days for an attachment to form.
Long term effects- Found the monkeys developed abnormally when they became adults. They were more agressive and less sociable than other monkeys. They also bred less often. When they became mothers, they neglected and sometimes attacked their children
What are the conclusions from Harlows study
Showed that attachment doesnt develop due to bieng fed, but as a result of comfort. Also showed the importance of quality of early relationships for later social development.
What is Practical applications (evaluation of Harlows study)
P- Has practical uses as shows the importance of emotional care in childcare
E- Schaffer and Emerson
E- Found that the mothers responsiveness was the most important in the formation of attachment
E- this led to practical applicatiosn, like helped social workers understand tthe risk of child neglect and so can intervene to prevent it
R- Shows how Harlows research has practical value
What are the two general evaluation points for animal studies
Problems with comparing results to humans
Ethical issues
What is problems with comparing results to humans (evaluation of animal studies)
P- There is a problem of generalising findings from animal studies to humans
E- studies such as Bowlby
E- many animal studies influenced research into human attachment, but there is a problem of generalising the findings to humans
E- human attachment is different to other animals, like mammalian mothers show more attachment to their young than birds do
R- So this means it may not be appropriate to try and generalise the findings from animal studies to explain human attachment
What are the ethical issues (evaluation of animal studies)
P- Ethical issues in the animal studies
E- Lorenz and Harlow
E- Created stress to the young animals as they were seperated from their mothers, and caused long term harm to the animals
E- However the experiment can be justified as it had a significant effect on understanding the process of attachment in humans
R- So could be argued the benefits outweigh the costs and is something to consider
What is innate and adaptive in Bowlbys Monotrophic theory
It explains how and why attachments form
Innate and Adaptive:
Bowlby proposed that attachment is innate, and adaptive. This is because it helps the infant survive, and ensures its safety, and so the infant will stay close to the person who will feed and protect them.
What is critical period in Bowlbys monotrophic theory
Critical period:
First 2 years the critical period, and most sensitive at 6 months. After 2 years the child will find it harder to form attachments if not already
What are social releasers in Bowlbys monotrophic theory
Social releasers:
Babies have particular features that trigger caregiving behaviours, like crying and big eyes. These help to form the reciprocal bond between caregiver and infant. Infants become most strongly attached to the person who responds most sensitively to their social releasers
What is monotropy in Bowlbys monotrophic theory
Bowlby believed that human infants have an innate tendency to become attached to one person in particular. And the more time spent with the primary attachment the better. He explained that the effects of seperation from the mother adds up and can have negative effects
What is the internal working model in Bowlbys monotrophic theory
Bowlby suggested that a child having their first relationship forms a mental representation of this relationship, and this will construct their working model for future relationships, and show them how they should act in act and expectations in them. So the attachments formed in the critical period will affect relationships later in life.
What are the points of evaluation for Bowlbys Monotrophic theory
-Supporting evidence that attachment is adaptive and innate- Lorenz
-Ethical implications- Burman
-Supporting evidence for the internal working model- Hazan and shavers
-Multiple attachments more important that monotrophy- Rutter
What is the supporting evidence that attachment is adaptive and innate (evaluation for Bowlbys Monotrophic theory)
P- Supporting evidence from studies that show attachment as adaptive and innate
E- Lorenz
E- Goslings formed an picture of their parents within hours of birth, and follow them around closely.
E- Lorenz belived that it has evolutionary value, as they are more likely to be safe, fed and learn how to find food, when they follow their mother.
R- However care must be taken when extrapolating results from gosling to humans, as it may not be the same
