Lectures 1-3 Flashcards
What did Franz (1963) say about babies?
What was his experiment?
Babies have a preference for looking at humans faces.
He used the “looking chamber” to record babies eye movements to different stimuli.
What is motherese?
A high pitched sing song style of speech and is used in all different cultures.
What did DeCasper and Fifer (1980) find and what was their experiment?
Newborns recognise their mothers voices. They tested this using a dummy which measured the baby’s sucking pattern on a dummy. The babies learnt to suck in a certain speed to get the mothers voice to play.
Eimas (1972) found what about babies?
They recognise different speech sounds that didn’t occur in their native language. However as they grow older they lose this ability.
What is interaction synchrony?
Infant mirrors the facial expressions and body movements of their social partner.
What is shared intentionality?
Collaborative interactions in which participants share psychological states with one another (for example problem solving activities).
What is the kewpie doll effect (Bolby, 1958, 1969)?
Young infants have physical characteristics that adults find attractive.
What is stranger anxiety?
( 3 things )
- Fear of unfamiliar people
- Strong between 5-7 months
- Lasts normally until 14 months
What is separation anxiety?
- Fear of being left by primary care giver
- emerges at 6 months increasing until 15 months, then gradually fades
What is social referencing?
An infants tendency to look to trusted adults for emotional cues in interpreting an ambiguous event.
Ainsworth (1978) identified 3 patterns of attachment
- Secure
- Resistant
- Avoidant
- (Later added disorganised/disoriented)
What is insecure avoidant attachment?
Not too bothered by stranger and mother’s departure, reluctant to cling and lack of delight when mother returns.
What is securely attached?
Crying when mother leaves, searches for her and is delighted when returns.
What is insecure attachment?
Cling to mothers but don’t show distress of departure, reuniting may bring joy and a lot of crying.
Benefits of secure attachment in the long term?
Basic trust, more intelligent, better development and optimism.
Nature vs nurture
Nature - genetics
Nurture - environmental influences
What is a neurodevelopment disorder/condition?
Genetic or environmental factors influence the development of the brain and/or nervous system.
Genotype?
Phenotype?
The genetic makeup of a person
Observable characteristics (hair colour)
What is a teratogen?
Environmental hazards with negative effects on prenatal development.
Maternal stress can be a teratogen
Smoking
Industrial chemicals
Heavy metals
Maternal age
What percentage weight is the brain at birth in comparison to its adult weight.
25%
What is myelination?
Process of costing the axon with fatty substance called myelin
Size constancy is assumed to be…
Innate
Experiment to test depth perception for babies is…
Visual cliff
By what age do infants have a visual recognition memory?
3 months
What are the three methods for assessing infant memory?
Habituation/dishabituation
Conjugate-reinforcement
Deferred imitation
What did they find from the mobile conjugate reinforcement procedure?
Infants appear to remember the specific details of the original stimulus.
For example, babies are more likely to kick to a similar mobile than a dissimilar one to the one they remember.
What was Bauer et al (2000) experiment on deferred imitation?
- Placed bar across two posts
- Hung a plate from the bar
- Struck the plate with a mallet
Babies remembered this up to 12 months later.
What is piagets 3 stage theory?
Cognitive development
Intelligence
Schemata
Three types of schemata recognition
Behavioural or sensorimotor- organised behaviour pattern.
Symbolic - mental symbols.
Operational - mental activities that the child performs on his or her objects of thought.
Three ways learning occurs using schemata
Organisation - combining schemata into complex structures
Assimilation - interpreting new experiences by incorporating them into existing schemata
Accommodation- modifying existing schemata to explain new experiences
4 key facts of piagets theory of development
- Four stages of cognitive development
- Stages occur in an invariant sequence
- Ages associated with stages are approximate
- Development is potentially influenced by environment
What age is object Permanence mastered?
18 months
