Slide Week 2 Flashcards
Human Development
The Study of changes in people from conception until death
What is Development
- The sequence of age-related changes that occur as we move from birth through to death
Encapsulates:
- Physical, emotional and cognitive changes
- Nature vs Nurture
- Continuity vs Transition
- Person vs Situation
Continuity vs Transition
The study of what stays the same in our lives vs what is changing
Types of Developmental Research
- Cross Sectional
- Longitudinal
Cross Sectional Research
- Studies various groups by category such as by age
- studies done in present time
Longitudinal studies
Studies a group of people over time to see how attitudes or behaviour change
Advantages of Cross Sectional Studies
- Gives information about age differences
- Are quick to do
- Are inexpensive
- Can supply a large sample
Disadvantages of Cross Sectional Studies
- Cohorts are difficult to separate
- Can be generalised
- No Historical continuity
Advantages of Longitudinal Studies
- Gives information about age changes
- Increased reliability
- More in depth information per participant
Disadvantages of Longitudinal Studies
- Expensive
- Time consuming
- Restricted by generalisability
- Small sample affected by dropouts.
Preferential Looking Behaviours
- Studies babies and gives them two images to look at
- Seeks to determine which image the prefer to look at.
Habituation Method
- Studies in babies to determine if they decrease their response to a stimulus if they are exposed to it repeatedly
- This concept states that an animal or a human may learn to ignore a stimulus because of repeated exposure to it.
Attachment Theory
Studies Attachment and separation anxiety
What is Attachment
- refers to the emotional bonds of connection between infants and their caregivers
What is Separation Anxiety
The emotional distress displayed by infants when separated from their primary caregivers who they have formed an attachment with
Harry Harlow - 1959
- Questions why do attachments form
- Asks do we seek food or comfort
- Studied infant monkeys with artificial mothers
Artificial Mother Experiment
Monkeys separated from mothers at birth were raised using two artificial mothers
- For four newborn monkeys the cloth mother lactated and the wire mother did not
- For another four newborn monkeys, the wire mother lactated and the cloth mother did not
Found there was a preference for cloth mother – regardless of which mother fed them, especially when fearful
What happens when attachments are not properly formed
Harlow found isolated infant monkeys showed:
- withdrawal
- rocking
- huddling
- unable to form sexual relationships as adults
- when females became mothers they tended to ignore them and abuse them when they felt distressed
John Bowlby - 1969
- Studied Attachment and Loss in orphans from WWII
- found infants biologically motivated to form attachments as a survival technique
- Found infants instinctively behave endearingly to trigger affection and protection in adults
- Repeated experiences with caregivers establishes a working model
Mary Ainsworth - 1967, 1978
- Developed the Strange Situation Procedure to assess quality of attachments between infants and caregivers
- Attachment depends on the relationship between mother and infant
- Babies not passive bystanders, their reactions can affect the caregivers behaviour
There are three types of attachment
- Secure Attachment
- Anxious-Ambivalent Attachment -
- Avoidant Attachment
Secure Attachment
Child tends to be playful, less inhibited, exploration-oriented, sociable
Anxious-Ambivalent Attachment
- Child tends to engage in visual checking signalling to reestablish contact.
- Calling, pleading, moving to reestablish contact, clinging
Avoidant attachment
Child tends to maintain proximity while avoiding close contact
Percentage of Attachment styles
- Secure: 75%
- Resistant: 15%
- Avoidant: 15%
Response to Separation Anxiety - Attachment Style
- Secure: Distressed
- Resistant: intense distress
- Avoidant: No Sign of distress
Stranger Anxiety response - Attachment Style
- Secure: Avoidance when alone, friendly when with parent.
- Resistant: Fear of stranger
- Avoidant: Plays with stranger
Parent Caregiving Style - Warm/Responsive
- Parent generally warm and responsive
- Good at reading cues and knowing when to be supportive and when to allow autonomy
- Creates secure attachment
Infant Attachment Style: Secure Attachment
- child welcomes close contact with caregiver
- caregiver becomes a secure base while exploring the environment
Adult Attachment Style: Secure
- finds it relatively easy to get close to others
- comfortable depending on others and having others rely on them
- no real fear of abandonment
- not afraid of others getting too close
Parent Caregivint Style: Cold/Rejecting
- distant, rejecting and not very responsive
- Child takes a lesser priority with concerns possibly lying elsewhere
- Creates Avoidant Attachment Style
Infant Attachment Style: Avoidant Attachment
- Insecure caregiver bond
- Characterised by little separation anxiety
- Tendency of the child to avoid or ignore the caregiver
Adult Attachment Style: Avoidant
- Uncomfortable getting close to others
- Difficulty trusting partners
- Difficulty allowing them to depend on us
- Not comfortable getting too close to others
- Finds intimacy difficult with love partners
Parents caregiving style: Ambivalent/inconsistent
- Inconsestent in response, sometimes warm sometimes cold
- Appears to have own agenda
- Is loving but doesn’t always show it in the best way
- Creates Anxious/Ambivalent Attachment style
