Define attachment
a close two way emotional bond, where both individuals see the other as important for them to be emotionally secure
Define imprinting
where mobile bird species attach to and follow the first moving object they see, at birth
Lorenz’s imprinting study
findings of Lorenz’s imprinting study
define critical period in relation to Lorenz’s study
Lorenz found there was a period of time where imprinting needs to take place, otherwise chicks won’t attach themselves to a mother figure
describe Lorenz’s sexual imprinting study and findings
found that when a newborn peacock, reared in reptile house at zoo, first observed a giant tortoise, as an adult the peacock aimed its courtings at tortoises
-found this whatever object birds were imprinted to would be the subject of their courtship (observed this occurred even from birds onto humans)
describe Harlow’s study on attachment
testing idea mother wasn’t based on feeding, and that soft objects can serve some of the fucntions of a mother
reared 16 monkeys with 2 wire mothers (a plain wire mother and a cloth covered wire mother)
Findings of Harlow’s study on attachment
Harlow’s follow up research study on these monkey as adults
These monkeys had maternal deprivation
•the group who had the wire mother with the feeding bottle were the most dysfunctional, but those with the cloth mother did also develop abnormal behaviour
• struggled forming mating relationships, more aggressive, less social, neglected, attacked and some killed their children
Suggested critical period for monkeys based on Harlow
90 days otherwise monkey will form no attachment
Strength and weakness of Lorenz study
•research support
•generalisability
- mammalian attachment system is more complex than birds (in mammals it is two way)
Strength and weakness of Harlow’s study
•application
•ethical issues
Describe Mary Ainsworth’s strange situation
controlled observation (2 way mirror) designed to test attachment • 7 stages, each 3 minutes long
Behaviours used to judge attachment
Findings of Mary Ainsworth’s Strange Situation
identified three main types of attachment based on distinct patterns
• secure : moderate stranger and separation anxiety
• insecure avoidant : little effect of separation and reunion
• insecure resistant : high separation and stranger anxiety
% of babies that were insecure avoidant (type … )
20-25%
Type A
(A)voidant type (A)
% of babies that were securely attached (type …)
60-75%
Type B
BS BULLSHIT
type B Secure
% of babies that were insecure resistant (type….)
3%
Type C
Describe Van Ijzendoorn and Kroonenberg study
what were they trying to study and the procedure
Studied the proportion of each attachment type 𝘄𝗶𝘁𝗵𝗶𝗻 and 𝗮𝗰𝗿𝗼𝘀𝘀 different cultures
-meta analysed 32 Strange Situations for assessing attachment of around 2,000 children
define a meta analysis
combination of research and findings from several studies on the same topic
- findings are weighted for its sample size
define cultural variation
the differences in norms and values that exist between people of different cultural groups
Findings of Van Ijzendoorn and Kroonenberg’s meta analysis
•most common attachment type was secure, like Ainsworth
—> although varied (Britain 75% , China 50%)
Describe 2 other studies of Cultural Variation
Italian study - 𝗦𝗶𝗺𝗼𝗻𝗲𝗹𝗹𝗶
Korean study - 𝗟𝗶𝗻
used strange situation
- found secure and insecure ratios were similar to most countries
- but most insecure, were insecure resistant (like Japan) due to rare separation in these cultures (similar child rearing style)
conclusions that can be drawn from studies on cultural variations in attachment
