Psychology Of Childhood Flashcards
Temperament
Individual differences in emotion activity level and attention that’s re exhibited across context and present from infancy
Between person approach:
Easy child, difficult child, slow to warm child
Within person approach:
Fear child, distress/anger child, attention span, activity level, smiling/laughter child
Biological families
Not possible to disentangle effects of genetics and environmental factors
Genetically informative research
Twin design: monozygotic vs dizygotic twins, twins reared apart vs twins reared together
Adoption design: biological and adoptive parents, adoptive vs non adoptive families
Adoption design
Biological families have “genetic plus environmental” parents
Biological parents share genes but not environment with child
Adoptive parents share environment but not genes with child
Parent s and child resemblance
variation due to nature
variation due to nurture
If trait variation entirely due to nurture
-correlation strong for non adoptive and adoptive but not adopted apart children
If trait variation entirely due to nature
-correlation strong for non adoptive, adopted apart but not adoptive children
Adoption study limitations
Adoptees not randomly placed into families, get chosen
Adoption studies not generalise to population at large
Prenatal influences not considered eg biological mother smoking
Adoption (especially at birth) is unusual event
Twin design
- comparing resemblance allows for rough estimate of separate genetic and environmental contributions to trait
- assessed with correlation between pair of twins, separate correlations for MZ and DZ twins
- MZ resemblance 100%
- DZ resemblance 50%
Child temperament traits and significant genetic influence
Consistently found MZ more similar than DZ variety of temperament dimensions:
- emotionality
- shyness
- sociability
- attention/persistence
- approach
- adaptability
- distress
- positive affect and negative affect
Iimitation of twin design
Equal environments assumption; assume similar for fraternal and identical twins, MZ share more similar environments
Twin studies not generalise to population at large; twins more susceptible to prenatal trauma leading to mental retardation
MZ twins not 100% genetically identical; various biological mechanisms lead to genetic differences between MZ
Heritability
- proportion of variance in population attributable to genetic differences between people
- Estimate only applies to particular population living in particular environment at particular time
Twin study of child temperament
Lemerey chalfant 2013
301 MZ twins, 263 DZ same sex, 243 DZ opposite sex
parent telephone interview and home visits
Finding 1: effortful control, negative affect and extraversion show high heritability; 54%, 79%, 49%
Finding 2: home environments under genetic influence affect personality
pediatric approach
definition of temperament
general term referring to ‘how’ of behaviour…differs from ability … and motivation… concerns the way in which an individual behaves
pediatric approach
constituents of temperament
a.r.a-w.a.r.ir.mq.d.as
activity level regularity approach-withdrawal adaptability threshold of responsiveness intensity of reaction quality of mood distractibility attention span
pediatric approach
typology of children
easy child: regular, positive mood etc
difficult child: irregular, high activity level
slow to warm: low activity level, low intensity of mood
personality tradition approach
definition of temperament
temperament is set of inherited personality traits that appear in early life
two defining characteristics: traits genetic in origin and appear in infancy
personality tradition
constituents
emotionality
activity
sociability
individual differences approach
temperament definition
constitutionally based individual differences in emotional, motor, attentional reactivity and self regulation
temperamental characteristics seen to demonstrate consistency across situations and stability over time
individual differences approach
constituents
fd.id.as-p.a.p.r.a/a
fearful distress/inhibition irritable distress attention span and persistence activity level positive affect/approach rhythmicity agreeableness/adaptability
commonalities of the temperament approaches
- temperament refers to individual differences not normative characteristics
- refers to set of traits
- reflect behavioural tendencies that are pervasive across situations and show stability
- emphasis on biological underpinnings
- emerges early in life
disagreements of the temperament approaches
- differing boundaries for temperament
- differing constituents (excluding activity level and emotionality)
- relationship between temperament and personality construed differently
heritabiltiy of temperament
EAS traits
- strongest evidence for EAS traits
- MZ twins: 0.63 emotionality, 0.62 activity, 0.53 sociability
- DZ twins: 0.12 emotionality, -0.13 activity, -0.03 sociability
- as whole temperament is moderately influenced by genetic factors, estimate is similar across ages
- stability in temperament is mediated by genetic factors , environmental factors account for age-to-age change
clinical application of temperament
- temperament is a departure from the ‘tabula rasa’ concept
- introduced the ‘goodness of fit’ concept
- advocate of interactionist, idiographic approach
goodness/poorness of fit
-when child capacities, motivations and temperament are either adequate or inadequate to master the expectations, demands and opportunities of environment, if inadequate can lead to maladaptive functioning and distorted development
temperament and subsequent adjustment
prior 1992
- relationships generally moderate strength; prediction from infancy is weak
- difficult and active babies at increased risk for colic, sleep problems, excessive crying and abdominal pain
- temperament difficulty associated with both internalising and externalising problems
experiment: linking temperament to internalising and externalising problems
- ages 9, 11, 13, 15 from NZ
- tester rating of temperament (lack control, approach, sluggishness) used to predict problem behaviour via parent/teacher reports
- results: lack control is best predictor especially for externalising problems
temperament in context
- not meaningful without reference to social context
- ‘difficult’ temperament associated with poor outcome sin western cultures
- ‘difficult’ babies had evolutionary advantage in Masai environment under harsh drought conditions
What is attachment
Strong emotional bond that forms in the second half of first year between infant and caregiver
Visible signs: warm welcoming, big smile, active effort to make contact, touching caregiver face, holding onto parent leg in unusual situation
Psychoanalytic theory of attachment
Baby become attached to mothers breast, then mother herself as source of oral gratification
Focus on innate drives and pleasure seeking
Emphasis on inner needs/feelings and mother-infant interaction
Love of object through association with oral need-gratification
Ethnological theory of attachment
Biological adaptation of infant-mother attachment
-nutrition, protection, secure base for exploration
Evolutionary advantage: proximity means safe and fed
Roots in set of instinctual infant responses, respond to each other’s behaviours
Learning theory of attachment
Infants become attached to mother as she provides food (primary reinforcement) thus she becomes a secondary reinforcer
Attachment develops
What is monotrophy in relation to attachment
“Bias of child to attach himself especially to one person” bowlby 1969
With fathers, siblings, peers
What are key characteristics of attachment
Emotional intensity
Proximity maintenance
Specificity of attachment figure
Distress upon separation
Development of attachment
Pre attachment
Attachment in making (6weeks-6months):
Scaffolding by care givers vs co regulation:
Clear cut attachment (6months -18months):
Reciprocal relationships (18-24months)
Measuring attachment
Quality or security of attachment varies
‘Strange situation’ Ainsworth 1973
Observe mother infant interaction in home from birth to 54weeks
Observations of attachment security lab
Classification of security
Insecure avoidant: happy to explore, usually not distressed by separation or on reunion
Secure: base exploration, distressed or not by separation, on reunion actively approach carer and distress decrease
Ambivalent-resistant : clingy, distressed by separation, reunion anger and resistance to comfort
Disorganised: display greatest insecurity, on reunion show confused behaviour or dazed facial expression
Antecedents to attachment
relationship construct but implicated mothers individual differences in attachment security
Accessibility and responsiveness of attachment figures are held to determine attachment security
How might temperament make a difference
Children’s temperamental characteristics DO play role in attachment security (Vaughn)
infants more distressed by removal of dummy were more likely to form insecure attachments (Bell, Weller, Waldrop)
Maternal sensitivity and temperament experiment
- Intervention study of 100 irritable first born infants from low SES families and 50 controls
- 50 infants experienced interventions of 3x2 hour home visits between 6-9 months
- at 9 months intervention group mothers were more responsive, stimulating, visually attractive and controlling of infants behaviour
- infant temperament also changed to be more sociable, self soothing and exploration
Consequences of attachment
Attachment quality tends to be stable over time
Secure attachment leads to higher self esteem, self confidence, social competence, positive affect
social smile
- emerges between 6-12 weeks old
- different stimuli elicit different types of smiles
- audience effect: infants purposeful look towards mother, mothers attentive behaviour modulates infant smile, but child nto smile at toys
