Lecture 11 - Attachment Flashcards
What is attachment? (early theories)
Attachment is a learned response
- emphasize feeding/food reinforcement
- attachment is a secondary consequence of food reward
ex. monkey w/ wire moms
What did the monkey with two wire moms experiment tell us?
Monkeys spent significantly more time with cloth mother than wire mother, regardless of who provided milk. Suggested that attachment might be a core primary goal of adaptive value. Source of comfort/support
What mechanism ensures non human infants stay close to their primary caregiver?
Imprinting (ex. baby birds upon hatching follow whoever they see first)
Preference for mother’s face in humans
- Bias in newborns to attend to faces over other stimuli speeds learning specific faces (mom’s)
- W/i a few months, infants show a selective bias for mom’s face over other faces
Bowlby’s view of attachment
Infant stores information about the attachment relationship. Stored internal working model of attachment is assumed to be the basis for children’s understanding of relationships later in life.
Measuring differences in attachment style
Strange Situation (structure obs.) - asses quality of attachment via looking at a range of behaviors across a sequence of episodes
What interactions did the Strange situation look at?
Caregiver - infant interactions Exploration (use of mother as a secure base) Brief separations from mother Encounters with strangers Reunion episodes
Three styles of attachment
Secure (65%), Insecure-Avoidant (20%), Insecure-Resistant (15%)
Secure (attachment style)
Actively seek proximity to caregiver upon reunion
Communicate distress openly, readily return to play
Insecure-Avoidant (attachment style)
Infants who do not seem distressed during separation
Ignore caregiver upon return
Insecure-Resistant (attachment style)
Distressed when the caregiver departs
Not easily soothed on return
Causes for variation in attachment
Interaction between features of the child (temperament/personality) and feature of the parent (parental sensitivity)
Individual temperament differences
Initial research pointed to early emerging/biological based individual differences…may be related to interactions with caregivers
Easy (temperament)
Positive mood, readily adjust to new situations, quickly establish daily routines
Difficult (temperament)
More negative mood, slow to adjust to new experiences, react negatively to novel stimuli and events, irregular daily routines, hard to comfort when upset
