John Bowlby
Founder of attachment on the central debates:
Primacy-infants ability to form secure attachments in first two years establishes attachment style for life.
Discontinuous-there are stages/qualitative shift in attachment
Nurture-it is parental responsively that creates the attachment.
All infants from enduring emotional bonds (attachment:
Beyond need of physical nourishment
Harlow’s wire mesh monkeys studies support the theory
Diss-attachment or disinterest in relationships
Only comes after losing a primary caregiver
Attachment does have a biological purpose
Helps infants maintain physical security from predators
Helps infants feel safe when exploring the environment
Stages of attachment
Stages of attachment
1. pr-attachment
a. Birth to 6 weeks
i. No awareness of being dependent on caregivers
ii. No awareness of being Independent form caregivers
iii. Infant allow other people to take care of them
2. Attachment in the making
a. weeks to 6-8 weeks
i. Infant learn distinguish
1. Between caregiver and self
2. between caregiver and stranger
ii. Infant develop “worries”
3. Clear cut attachment
a. 6-8 months 18024 months
b. Separation anxiety
i. Visceral fear of physical separation from mother
4. Reciprocal relationship
a. 24 months and after
i. Children can contribute to equilibrium of interactions
ii. Childs responsively to parents increases
iii. Mirroring of affect becomes ore mutual
iv. Response-an intentional action from another person.
Internal working models
Infants from mental representations of attachment that becomes the map for all future relationships
Schema for how relationships will be experienced
Primary task of caregiver in firs two years is to offer infant a secure base
Secure base
Solid emotional bonds
Foundation for being in the world
Security to explore world, without it you do not
Security of identity, self of self

a. Children don’t have the theory of mind
i. Control someone’s mind-be able to fool them
ii. Do you feel bad you ate the cookie
The world is seen solely on perspective
Inability to understand what happens in another’s feeling or mind
(talking on the phone and showing them a picture threw phone)

Infants monkeys clung to terrycloth mother weather or not they had the bottle
Infants in both experimental group:
Grew up to be more aggressive and fearful than in control group
As adults could not engage in normal sexual relationships
Self destructive across life span, hair pulling, gnawing on slef.

Strange Situation
Technique for measuring quality of attachment
A procedure designed to assess children attachment on the basis of their response to a stronger when they are with their mothers, when they are left alone, when they are reunited with their mothers. \
1. Mother and infant enter the room
2. mother sit, infant explores
3. stranger enters
4. mother leave room
5. mother returns to room, stranger leaves room
6. Mother leaves room
7. stranger returns to room

Measures child’s ability:
Be comfortable by mother; Be comforted by a stranger
Mary Ainsworth
She designed the procedure strange situation
Studied with Bowlby John hopkins

“Three mountain problem”
They only see what they actually see and can not think about what the other person sees
A failure to take another person perspective
Piaget and Inhelder: mountain diorama studies
Part of the Spatial perspective taking, where children look at what the other child is looking at but when asked what the child sees on the other side they still think they see the same thing as them.
Egocentric speech
When two children take conversational turns, but do not engage in real conversation with each other. “collective monologues”
Maynard the Cat studies
They would put at mask on a cat and ask kids questions to figure out if it is still the cat or not, 3 year olds have a hard time with this but ages older can figure it out.
Flavell studies on dif between
Appearance and reality
They showed the children many different things that looked like other things to see if kids could figure out what they were
3 year olds usually got it wrong, 4 year olds transition stage, 5 answered them like adults
Flavell studies on dif between Precausal Reasoning
When children are asking a lot of question on why and how? This is because they are unable to figure out cause and effect situations.
Percausal thinking-the reasoning of young children that does not follow the procedures of ethical deductive or inductive reasoning.
