chapter 14 Flashcards
define development
physiological, behavioural, cognitive, and social changes that occur throughout human life, which are guided by both genetic predispositions(nature) and by environmental influencers(nurture)
define infancy
development of stage that begins at birth and continues to one year of age
define childhood
periods between infancy and onset of puberty
define adoloscence
years b/w onset of puberty and the beginning of adulthood(emerging, early, middle and older adulthood)
define conception
occurs when an egg from mother is fertilized by a sperm from the other.
ovulation?
when an ovum or egg which has been stored in one of the mother’s two ovaries, matures and is released into fallopian tube
largest cell in the human body?
egg
zygote is a fertilized _____.
ovum
define zygote
within several hours of conceptions, half of the 23 chromosomes from the sperm fuse together, creating zygote
once the zygote attaches to the wall of uterus , it is known as _____-.
embryo
during which phase major internal and external organs are formed
embryonic phase, last for the next six weeks
inner layer of embryo forms _______ and outer layer forms _________.
embryo itself, surrounding protective environment that will help the embryo survive during pregnancy
what are the 3 major structures during embryonic stage
AMNIOTIC SAC
PLACENTA
UMBILICAL CORD
DEFINE AMNIOTIC SAC
fluid-filled reservoir in which the embryo(soon to be known as a fetus) will live until birth
functions of amniotic sac
-cushion against outside pressure
-temp regulator
_______ is an organ
that allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material
placenta
_________links the embryo
directly to the placenta and transfers all material to the fetus.
umbilical cord
what two organs protect the fetus from many foreign agents?
placenta, amniotic sac
at what time ford embryo becomes a fetus after conception?
ninth week after conception
defining characteristic of the fetal stage
is.
growth
substances that can harm the fetus despite protection from placenta and umbilical cord are known as ____?
teratogens- general environmental factors, such as air pollution and radiation, but
also the cigarettes, alcohol, and drugs that the mother may use.
how does cigarette smoking affects the child?
reduces the blood
oxygen for both the mother and child and can cause a fetus to be born severely underweight
name the condition caused by maternal alcohol drinking that can lead to numerous detrimental developmental effects.
fetal alcohol syndrome (FAS)
name the detrimental developmental effects caused due to FAS
limb and facial abnormalities, genital anomalies, and intellectual disability.
how much alcohol consumption is safe for pregnant women?
none
what is considered
one of the greatest risk factors facing unborn children.
maternal drug abuse
how does environment in which the mother is living has a major impact on infant development?
ex- children born into poverty are also more likely to be exposed to teratogens.
development begins at the moment of?
conception, when sperm merges with egg
the fetus is protected by _______-
amniotic sac
understanding cognitive development by observing the behaviour of infants is through the use of the ?
habituation technique
define habituation?
decreased responsiveness toward a stimulus after it has been presented numerous times in succession.
Jean Piaget developed his theories of child development by ?
observing the behaviours of children.
define schemas
patterns of knowledge in long-term memory- that help them remember, organize and respond to info
what is the theory given by jean Piaget?
theory of cognitive development
1. children have cognitive structure
2. children are not passive, they actively acquire knowledge
3. children are different from adults
4. children may start various stages earlier than others, and this may
depend on country they live in
according to Piaget, children use both ______ and _______ to develop functioning schemas of the world?
accommodation
assimilation
different between assimilation and accommodation?
assimilation- use already developed schemes to understand new info( children fit existing schema to the new info and label the new info to the existing knowledge)
accommodation- learning new info and thus changing the schema
what was Piaget’s most important contribution to understanding cognitive development, and the fundamental aspect of his theory
idea that development occurs in unique and distinct stages, with each stage occurring at a specific time,
in a sequential manner, and in a way that allows the child to think about the world using new capacities.
what are Piaget’s Stages of Cognitive Development
- sensorimotor- Birth to
about 2 years - pre-operational- 2 to 7 years
- concrete operational- 7 to 11 years
- formal operational- 11 years to
adulthood
at what stage babies form their first schemas using primary senses?
sensorimotor stage
define object permanence?
child’s ability to know that an object exists even when the object cannot be perceived
acc to Piaget’s theory of cognitive development children begin to use language and to think more abstractly about objects, with capacity to form mental images
preoperational stage
what is the stage attainment in pre-operational stage?
egocentric-unable to readily see and
understand other people’s viewpoints.
what is theory of mind?
ability to take other person’s viewpoint
_________- is marked by more
frequent and more accurate use of transitions, operations, and abstract concepts, including those of time, space, and numbers
concrete operational stage
An important milestone during the concrete operational stage is the ________.
development of conservation- understanding that changes in the form of an object do not necessarily mean changes in the quantity of the object
_________- marked by the ability to think in abstract
terms and to use scientific and philosophical lines of thought
formal operational period
what is the theory given by Lev Vygotsky?
sociocultural theory - argue that cognitive development is not isolated entirely within the child
but occurs at least in part through social interactions- idea of community learning
what are child’s social skill?
the ability to understand, predict, and create bonds with the other people
in their environments
_________ is known as consciousness, and the content of consciousness is known as the _______.
self-awareness, self-concept.
define self concept?
is a knowledge representation or schema that contains knowledge about us, including our beliefs about
our personality traits, physical characteristics, abilities, values, goals, and roles, as well as the knowledge that we exist as
individuals
make comparisons with other children, a process
known as?.
social comparison
mention the critique of Piaget?
- Development does not occur in distinct stages
- Children understand quite a bit more than they are given credit for
(adults might not be as developed cognitively) - Children are not as egocentric as once thought
- Theory of Sociocultural Learning (Vygotsky):
-Cognitive development not entirely “in” child; rather learning depends on cultural and educational experiences
-Extension: Community Learning Theory – where child is both “teacher” and “learner”
define attachment?
The emotional bonds that we develop with those with whom we feel closest,
and particularly the bonds that an infant develops with the mother or primary caregiver
harlow&harlow through their theory on attachment concluded that?
Both monkeys and human babies need
a secure base that allows them to feel safe.
acc to Harlow and Erickson , most important goal of infancy was the development of a?
basic sense
of trust in one’s caregivers
in harlow and Harlow theory the monkey reared?
reared in isolation
reared with surrogates-wire mesh or soft terrycloth
name the laboratory test created by Mary Ainsworth that measured an infant’s attachment to his or her parent.⭐️
THE STRANGE SITUATION(separation anxiety, 9-18 months)- a measure of attachment in young children in which the child’s behaviours
are assessed in a situation in which the caregiver and a stranger move in and out of the environment
Social development requires the development of a _______ from which children feel free to explore.
secure base
attachment style refer to?
the security of this base and more generally to the type of relationship that
people, and especially children, develop with those who are important to them
