developmental 2 Flashcards
(133 cards)
baltes model of development - what are the 3 influences
normative age graded influences (starting school ,puberty)
normative history graded influences (ww2, natural disaster)
non normative life events (divorce, injury, lottery)
bronfenbrenners ecological model of human dev and the 4 nested settings
microsystem - what they experience in given setting - childs home
mesosystem - links across settings that individual participants in - childs home affects school performance
exosystem - links to settings the individual does not directly participate in - mothers work affecting behaviour and parental care
macrosystem - pattern of ideology and organisation in society/subculture - parent work environment affected by hours, pay etc in society
tomasello and humans vs apes
1999 - dif between humans and apes is that humans understand others are intentional agents like the self
this facilitates joint attention and imitative learning
2 year old children better than chimps and orangutans at social cognitive skills
evolutionary dev and play differences
young female chimpanzees more likely to carry rocks/stick dolls than males. does not necessarily mean the behaviour is innate in humans. we have vastly different societies, it may be an imitation of tool use too (females use more tools)
types of influences on development
normative - happens to everyone
individual
age graded - puberty
smith and thelan 2003
babies could complete the A not B task when stood up at 10months old
when do infants first start focusing on inner features, and application
2 months
hainline 1998 - may help them focus on most important stimuli
can recog mother 14days but not if wearing a hairnet
adult mechanisms in facial recognition
- disproportional inversion effect - much better at upright faces, stronger effect for face vs non face
have holistic processing - info from whole face
susilo 2013 face perception
positive association between age are facial recog abilities - supporting late maturation hypoth
williams syndrome and prosopagnosia
will - process faces atypically and have prolonged face gaze
pros - face blindness due to damage/abnormalities in right fusiform gyrus
pascalis 2002 and monkey faces
6m can tell between different human and monkey faces
not at 9m - only if early exposure - due to synaptic pruning
pascalis and face space
idea that there’s an FS framework. new faces are encoded in terms of deviation from the norm face
age 5 -> ya capabilities
explains other race effect - “they all look the same”
infants innate system may initially play a role inbiasing the newborns visual system towards faces in their environment, but nurture is implicated in all aspects of the development
other race effect
adults are poorer at discriminating faces of other races compared to own. 3m olds, not newborns, prefer own race
sangrigoli 2005 looked at korean adults that had a white adopted family, more accurate with white faces
uses of face perception
detect species, sex, race, identity/recognise, mood and state, intent and truthfulness
evidence for innate facial recog
fantz 1961 showed that babies 1-15wks preferred more complex image - scrambled and normal faces > black head
goren et al 1975 - used moving stimuli and newborns tracked schematic face more than other two
evidence for empiricist facial recog - over time
- johnson et al 1991 - replication
- by 3 months no longer track faces more
- created johnson and morton 2 process model
- CONSPEC: Early system (subcortical structures) biases infants to orient towards faces
- CONLEARN: Later taken over by more mature system (visual cortex) and more precise recognition
crookes and mckone facial development
face-specific perceptual development theory - FP develops into late childhood due to experience - allowing more coding of novel faces or more exact comparison to distractors at retreival
holistic processing develops - with strong perceptual info across the face and processing second-order info (such as spacing between features)
counter is face space
qual vs quant chnage on faces
no qual change from age 5 to adulthood (inversion effects, attractiveness, other race and how young children can encode novel face after 1 trial)
quant - early maturity of holistic processing rather than ongoing development
adult levels of holistic processing are present in early childhood - qualitatively present; quantitatively at adult strength
3 core executive functions
- inhibition - ability to control attention/behaviour/thoughts/emotion and override a prepotent response
- working memory - holding info in the mind whilst also processing and manipulating
- cognitive flexibility - changing perspectives/approaches to a problem, flexibly adjusting to new demands/rules/priorities
diamond 2002 inhibition
more time can help children compute and reach right answer
allows the prepotent response to race to the response threshold then fade, allowing the correct response to follow through
subthalamic nucleus prevents premature response
inhibitory control through development
rapid growth in childhood - 30% button pressing accuracy ages 3-6
early life inhibition predicts health in adolescence and adulthood
Growth curve modelling – Continued maturation of error-processing abilities supports protracted development of inhibitory control over adolescence.
can also decline in older age - seen in worse scores at inhibiting visual distractions and ability to suppress irrelevant info
development of working memory
WM relies on dorsolateral prefrontal cortex , whereas just holding info in mind (short term mem) does not
1 item at 6m, 3-4 age 1
no comparable tasks for infants and adults
can use BDS (backwards digit span) - is incredibly difficult for children, cannot get past three digits
what is cognitive flexibility
one aspect is ability to change spatial perspectives or interpersonal perspectives (to do this we need to inhibit previous perspective and activate a dif one with WM. CF also seen in thinking outside the box, being able to adjust to demands, take opportunity and admit you’re wrong
dimensional card sort test
1996
cognitive flexibility
by age 4, child can sort into colour or shape, but when the rules change to the other dimension they keep making the same mistake of the first rule
