attachment Flashcards
Lorenz 1935
Investigate mechanics of imprinting
Imprinting
Where animals learn their sense of species by following a larger animal presented to them at birth
Lorenz findings
Incubated only followed him - no bond with mother - imprinting after 4-25 hours - incubated geese tried to mate with humans not gesee
Lorenz AO3
Ethical issues + influenced bowlby + shows effect of relationships on future relationships - not genralisabke to humans
Harlow 1958
New born monkeys died if left alone but survived if given cloth
Harlow procedure
Baby monkeys presented with two mother models - one with milk but no cover the other with fur cover but no milk - chose cover mothers witlhen scared.
Maternal deprivation
Monkeys raised by wire models had less skills, reduced mating and become neglectful mothers
Critical perioud
If a pcg not introduced within 90 days no geniune bond formed - maternal deprivation takes place
Harlow AO3
+ resurch support from lorenz - not genralisable to humans + real world applications to humans - ethical issues - traumatised and dead monkeys
Operant / classical conditioning in attachment bonds
Bonds formed through contitioning with positive and negative reinforcement the infant associates pcg with attending to their needs - better care = better bonds
Attachment as a secondary bond
Attachment learned as a means of satisfying primary drive ie physiological needs
Bowlby 1988
Emphasis on childs atta hment to primary attachment figure - more time with paf the better the relationship
Law of continuities
More consistent care results in better relationship
Law of accumulated separation
Trauma builds up each time paf is seperated from infant
Internal working model
Infant builds scheme of relationship with paf and applies it to future relationships and parenting styles
Bowlbys monotropic theory AO3
-lack of validity, schaffer and emplerson 1964, infants occasionally formed bond with secondary care giver as well, does not suggest that pcg attachemnt diffrent from any others + social release supports, brazelton et al 1975, stopped moving when left alone, mechanism for soliciting care + bailey et al 2007, studed binds between pcg and infant if pcg had poor bond with own pcg more likley to have poor bond with own child
Ainsworth 1978 - strange situations
Studied atta hment style between pcg and infants between 18 mths and 9 yrs old by putting them through 8 ~3minuet trials
Strange situatiins trials
1 - mother baby and experimenter 2 - mother and baby only 3 - mother baby and stranger 4 - baby and stranger only 5 - mother and baby 6 - baby only 7 - stranger and baby only 8 - mothrr and baby only
Scoring of strange situations
Babys scired on 4 criteria: - proximity and contact seeking - contact maintaining - avoidance of proximity / contact - reisrance to contamct / proximity Recored every 15 seconds on scale of 1-7
Reults of strange situatikns
Determined three attachment types, insecure avoidant (type a), secure (type b ) and insecure resistant (type c) a fourth was latter defined in a 1990 study as disorganised
Type A insecure avoidant
No distress when m leaves - plays normally with s - little to no intrest when m returns - comfoted by m and s equally - does not orientate to m when exploring - 15% of attachment styles - pcg withdraws when distressed
Type B secure
Distressed when m leaves - avoident when alone but not when m present - positive to m return - m forms safe base to explore from - 70% of attachment styles - pcg attentive to needs
Insecure resistent
Distressed when m leaves - avoids strangers at all times - approaches m on return but resists contact - explores less - 15% of attachment styles - pcg inconsistent with needs
Strange situations AO3
+wolf and van izendoorn 1997, correlation between parent sensitivity and attachment style - correlation weak - alt theorys, kagdn 1984, attachment style dependent on temprement + recreated in germany - lab - ethnocentric - only mother not pcg - ethics distressing infant
