developmental psychology Flashcards
maturational theory of Gesell
biologically directed maturation; the same developmental patterns independent of environmental input
cephalocaudal trend
from head to foot
proximodistal trend
from centre of body to peripheral
McGraw- motor development
environment can shape motor development, twin study extra training in swimming skating and climbing
dynamic systems theory
development is a complex interaction between properties of the system and the environment
system
collection of component that are interrelated (body, family)
dynamic system
collection of components that influence each other. describes how a state changes another state over time, self-organisation
Esther thelen Dynamic system theory
motor development is shaped by central nervous system, motor skills and environment
behaviourism child development
child is passive in its development, environment shapes development
law of recency
likelihood of repetition of recent acquired behaviour is higher
law of exercise
practice strengthens stimulus response connections
constructivism
acquiring knowledge and skills is the result of thinking big children themselves. children learn by connecting new information to what they already know (piagets theory and information processing approach)
assimilation
fit knowledge into preexisting schemes
accommodation
modify preexisting schemes
equilibration
schemes are in balance
information processing theory
individuals process info similar to a computer. to understand behaviour we need to understand the mental processes underlying the association between init and output
social constructivism
social environment is a critical guide factor in development
zone of proximal development
skills that are just a bit too difficult but can be learned with help
scaffolding
adopt instruction to the level of the child
cognitive adaptations
children developing cognitive awareness of the world as a result they become better able to understand their world
functional invariants
processes that o not chang during development, such as accommodation and assimilation
sensorimotor stage
first stage, though is based primarily on perception and action and internalised thinking is absent. from birth to 2 yrs
preoperational stage
egocentrism, animism, contraption. under the age of 7 are unable to coordinate aspects of problems in order to solve them
concrete operations stage
conservation and seriation understood, third stage, reasoning is said to become more logical, systematic and rational in its application to concrete objects
formal operations stage
fourth stage, in which the individual acquires the capacity for abstract scientific thought, this includes ability to theorise about impossible events and items
animism
children tend to attribute life like qualities to inanimate objects
centration
the focusing or centring of attention on one aspect of a situation to the exclusion of others
bottom up
building complex systems of knowledge from simpler origins
top down
the state of the system is specified or presumed, and then working to discover its components and their development
connectionism
in which computers are programmed to stimulate the action of the brain and nerve cells
introspectionism
in which observers were ask to reflect on their thoughts feelings and perceptions
law of effect
hates that he likelihood of n action being repeated is increased if it leads to a pleasant outcome, and decreased if it leads to an unpleasant outcome
reductionism
the claim of complex behaviours and skills such as language and problem solving are formed from simpler processes, such as neural activity and conditioning
precocial species
those species of animals where the young are able to locomotive almost immediately after birth or hatching
monotropy
the view that the infant has a basic need to form an attachment with one significant person
oedipus complex
young boy develops sexual feelings toward his mother but realises that his father is a major competitor for her sexual affections
castration complex
where the young boy fears castration at the hands of his father
electra complex
where little girls develop feelings toward their father and fear retribution at the hands of their mother
reaction formation
the individual may react often unconsciously to negative aspects of their personality
humanistic theory
emphasises that humans have free will and are motivated to fulfil their potential
zygote
fertalization to week 2
embryo
week 2 to week 12
foetus
week 12 to birth
morula
(day 3) ball of 16 cells cell differentiation starts
blastula
day 4-7, cavity arises, embryo arises out of inner cells implantation in uterus
gastrulation
week 2 the formation of the 3 germ layers by migration and differentiation of blastula cells
ectoderm
skin hair and nervous sytem
mesoderm
muscles and bones
endoderm
most other organs
neurulation
week 3 the formation of the neural plate, neural groove and neural tube from the ectoderm
neurogenesis
birth of new neurons, differentiation and migration of cells from neural tube
complete little human, organogenesis is finished in week..
8
rating reflex
first moving away from touch later towards it
vestibular apparatus
(in the inner ear) muscle tension, hearing vision and feeling
kangaroo method
skin to skin contact, baby moves together with parent
critical period
per in which specific development is optimal, system is vulnerable for lesions
crossectional design
not the same children, measuring children at different ages
constructivism, development of new perceptual abilities through interaction of
biological maturation and the child actively exploring the external world
ehtology
approach which empasizes the evolutionary origins of many behaviour that are important for survival
mechanism
(causation) “how does this behaviour occur in an individual?”
adaptive value
(function) why is this behaviour adaptive for the species?
ontogeny
(development) how does this behaviour arise in an individual?
phylogeny
(evolution) how does this behaviour arise in the species?
id
motions, impulses, desires
ego
mediation between reality and desire
superego
the conscious
insecure resistant
child keeps crying when caregiver comes back, resisting comfort
ambivalent
they seek contact with caregiver, but also hit and kick caregiver
insecure disorganized
do not know how to react, seem to be absent minded, repeating behaviour, not really playing and exploring
genetic epistemology (Piaget)
study of formation (genesis) of knowledge and how we know what we know (epistemology)
assimilation
integrating of new experiences into preexisting schemes
accommodation
modification of preexisting schemes in order to adapt to the environment
reflexive schemes
use of innate reflexes
primary circular reactions (1-4 m)
focused on own body not external world, repetitive behaviour
secondary circular reactions
focused on external world, repetitive behaviour (grasping, dropping object)
coordination of secondary chemes
goal directed behaviour, combining two schemes , children still make a not b error
A not B error occurs probably because
incomplete object permanence, mental representation present but no response perseveration
tertiary circular reactions
12 to 18 months, exploring new possibilities of objects, repetitive behaviour, no longer a not b error
mental representations/ beginning of thought
invention of new means through mental combination (trial and error no longer necessary), object permanence is fully understood
altirical species
in which the young are incapable of moving around on their own and are dependent on their parents for food and safety
precocial species
in which the young are physically mobile and able from the moment of birth or hatching
nativism
view that many skills or abilities are native or hard wired into the brain at birth, the result of genetic inheritance
empiricism
view that humans are not born with built in core knowledge or mental content and that all knowledge results from learning and experience
standardised test
test os a psych construct such as personality
genetic determinism
the hypothesis that people come who they are as a consequence of their genetic inheritance
familial resemblance
the resemblance between relatives whose genetic relationship to each other is known
missing heritability
the failure to find any of the genes associated with cognitive abilities
environmental drift
changes in developmental functions that result from and are in the direction of changing environments
flynn effect

developmental programming
the hypothesis that prenatal conditions have detrimental effects on health into adulthood
ultradian rhythm
rhythms or cycles that repeat in less than 24 hour period
maturation
aspects of development that are largely under genetic control and hence largely uninfluenced by environmental factors
paradigm
pattern or sample, the term is now used to a theoretical or philosophical framework in any scientific discipline
organismic world view
the idea that people are inherently active and continually interacting with the environment
mechanistic world view
the idea that a person can be represented as being like am machine, which is passive until stimulated by the environment
cohort
group of people who were raised in the same environment or who share certain demographic characteristics
