Chapter 4(cours 1) Flashcards
Which of the following topics would not be studied by a developmental psychologist?
a
How infants and children react to familiar individuals and strangers from the time they are born until they are five years old
b
Whether sleep habits are associated with academic achievement in 10-year-olds
c
Whether changes in cognitive functioning are observed from adulthood into old age
d
Whether three-year-olds engage in different types of play than five-year-olds or seven-year-olds
b
Whether sleep habits are associated with academic achievement in 10-year-olds
Biological changes that occur over time are part of what developmental psychologists study. Reactions to strangers (attachment research) are influenced by the caregiver-child bond, and stages of development influence the type of play based on age. Developmental researchers are also interested in cognitive (or brain) development in early childhood through old age. We’ll talk about each of these areas of childhood developmental research throughout the chapter. We won’t cover sleep until states of consciousness in Chapter 6.
Examining how language develops over the first two years of life is
social or cognitive
cognitive developement
Studying how the characteristics of children’s friendships change as they age
is cognitive or social development
social development
Studying how children process and interpret the behaviors of their peers at school is
what type of cognition
social cognition
lien entre chromosomes et Down syndrome
in the case of children with extra chromosomes, such as those with Down syndrome
What is an ectopic pregnancy?
Tubal pregnancy, when a fertilized egg develops outside the uterus (usually in the fallopian tube). High risk for rupture and death for both mother and zygote
whereas the uterus is a muscle that can expand (as the zygote grows) and contract (to expel the fetus during childbirth), the fallopian tubes do not have this ability. For this reason, pregnant women may have to terminate their pregnancy to avoid the possibility of a ruptured fallopian tube, which can result in death
What is the defining feature of the period of the zygote?
a
An egg is released from one of two ovaries
b
Refinements and finishing touches
c
Rapid cell division
d
The emergence and development of major bodily systems
c
rapid cell division
How is an ectopic pregnancy problematic?
a
The fallopian tube cannot expand to support a growing zygote or contract during childbirth.
b
The uterus cannot expand to support a growing zygote or contract during childbirth.
c
An ectopic pregnancy is not problematic and can proceed without intervention.
d
The uterus could rupture as the zygote grows, resulting in harm to the pregnant woman.
a
The fallopian tube cannot expand to support a growing zygote or contract during childbirth.
name types of twinning
Monozygotic or identical twins
Dizygotic or fraternal twins
Think about the process of twinning, as described above. Which of the following statements is correct?
a
Monozygotic or identical twins can be different sexes.
b
It is possible for a woman to be pregnant with dizygotic or fraternal twins that were conceived by sperm from two different men.
c
Some dizygotic or fraternal twins are genetically identical.
d
Dizygotic or fraternal twins are more alike genetically than two siblings who were born years apart.
b
It is possible for a woman to be pregnant with dizygotic or fraternal twins that were conceived by sperm from two different men.
The rapid changes that take place during this period proceed according to……………… and ………………..
the cephalocaudal
proximodistal principles of development
Cephalocaudal development refers to the idea that
significant changes occur in the brain and the head before changes happen in the extremities.
at nine weeks gestation—the head of the embryo is much larger and more developed than the feet or the toes, which are not even visible
Proximodistal development refers to the idea that
significant development occurs first at centrally located features, such as the heart or the lungs, before occurring at more peripheral locations, including the hands or fingers
What principle of prenatal development is shown in this figure? la croissance de la tête
a
Implantation
b
Cephalocaudal development
c
Proximodistal development
d
Ectopic pregnancy
b
Cephalocaudal development
By the end of the period of the embryo, all major bodily structures are ……………, but the embryo……………….
formed
cannot yet survive outside of the uterine environment.
during which period the child in the womb develop the sulci and gyri (the bumps and grooves) that are characteristic of adult brains?
during the period of the fetus
during the last weeks of gestation
Due to medical advances, fetuses can survive outside the uterus after about ….how many weeks? but ….lien avec brain development
22 weeks
However, significant brain development occurs between week 22 and birth. As shown here, fetal brains develop the sulci and gyri characteristic of adult brains only a few weeks before birth.
explain the period of the zygote-how many weeks, what happens
- from 0 to 2 weeks of gestation, ready for implants, the rapid cell division stage
name the periods that the prenatal development is divided, (3)
period of the zygote
period of the embryo
period of the fetus
explan the period of the embryo: how many weeks and what happens
2 to 8 weeks of gestation. It is when the majority of major body structures are formed: organogenesis (generating the organs).
explain the period of the fetus, how many weeks and what happens
from 9 weeks until we are born (38,39,40 weeks). The longest time is the period of the fetus. A lot of refinement of the structures that have been formed, gaining weight in the last few weeks.
The fetus gains weight and moves into the head-down position that is preferred for childbirth. Significant advances also occur in terms of brain development
what is the name of the process that generates the organs during the period of embryo?
organogenesis
when does the child in the womb develop sulci and gyri (the bumps and grooves) that are characteristic of adult brains
during the last weeks of gestation during the period of fetus
What is the defining feature of the period of the fetus?
a
Implantation of the blastocyst in the uterine wall
b
The brain develops sulci and gyri
c
Rapid cell division
d
The emergence and development of major bodily systems
b
The brain develops sulci and gyri
The brain develops more completely, and the fetus moves so that the head faces the cervix to prepare for childbirth during the period of the fetus.
the developement of the baby depend on which factors? whether the impacts are positives or negatives
the general health of the mother
the food she eats
the environmental agents to which the mother is exposed
how de we name the environmental agents or substances that negatively impact prenatal development in the womb?
terotogens
give examples of terotogens?
tobacco,
alcohol
over-the counter or
prescription medications
viruses
illnesses thant be transmitted from pregnant woman to their developing infants
l’intensité des impacts of teratogens dépend de…
dose(how much of this potential agent is she taking)
timing in her pregnancy(at which week did she take it)
cumulative effects(the possibility that the pregnant woman may have been exposed to more thant one terotogen and that the effects of multiple teratogens working in combination may be difficult to disentangle)
Which of the following is not a teratogen? explain why?
a
Maternal mental illness
b
Cigarette use
c
Illegal drug use
d
Environmental toxins
a
Maternal mental illness
Teratogens originate from outside the mother’s body and could harm a growing fetus. Drugs, toxins, and viral infections are teratogens.
Which of the following is true concerning the ethics of conducting experiments to determine whether teratogens cause negative outcomes in developing humans? explain
a
It is unethical to randomly assign pregnant women to an experimental condition (e.g., exposure to teratogens) that might negatively impact their developing infant.
b
It is unethical to conduct experiments on teratogens in humans unless their participation is expected to benefit them directly.
c
It is not unethical to assign pregnant women to any experimental condition as long as they are aware of the possible risks beforehand.
d
It is important to know definitively whether an environmental agent is a teratogen, so such research is warranted, even when conducted with humans.
a
It is unethical to randomly assign pregnant women to an experimental condition (e.g., exposure to teratogens) that might negatively impact their developing infant.
We can’t randomly assign participants to a condition to receive a treatment we know will harm them when they won’t receive any benefits. Only others will benefit from the knowledge we gain.
in which period of the prenatal development, the teratogens exert the most negative effects ?
during the period of the embryo
why the most negative impacts of terotogens are during the period of the embryo?
1) this is because it is during the period of the embryo that most major bodily structures are being formed
As such, exposure to harmful environmental agents can cause significant negative effects
2) because many women may not realize they are pregnant until after this important period of prenatal development has passed. As such, women who are planning or attempting to become pregnant should abstain from known teratogens
when the teratogens have less impact on the baby in the womb? BUT what happens to the brain during the fetus period if terotogens are present?
during the fetus and the zygote period
but may have significant impacts on brain development and cognitive functioning over the long term
Which of the following statements about teratogens is incorrect?
explain
a
Teratogens cannot cause any negative developmental effects before a woman knows she is pregnant.
b
Teratogens do the most damage to major bodily structures during the period of the embryo.
c
Exposure to teratogens during the period of the fetus can cause damage to the brain and negatively impact cognitive functioning over the long term.
d
Women who are attempting to become pregnant should limit their exposure to known teratogens.
a
Teratogens cannot cause any negative developmental effects before a woman knows she is pregnant.
Whether a woman knows she’s pregnant or not does not affect when teratogens harm a zygote or embryo. That is, teratogens will affect zygotes and embryos regardless of the mother’s awareness of either. For example, drinking water with high levels of lead (even though the mother doesn’t know there’s lead in the water or that she’s pregnant) will harm a fetus.
an hypothese why during the zygote phase, the teratogens do not really impact the zygote:
blastocyst, because it is not implanted and it is just free flotting through the fallopian tube, it is not really sharing anything with the mother yet. So, it is usually susceptible to teratogens during this phase.
- On the other hand, you are more susceptible to miscarriage at this point, if something’s not going right at this point.
qui s’occupe de dire si tel recomandation est bonne ou non pour le faire en lien avec les teratogens?
Centers for Disease Control and Prevention
Infants who have been exposed to alcohol during pregnancy may be identified as having
fetal alcohol spectrum disorder (FASD)
what is FASD
FASD represents a range of conditions associated with being exposed to alcohol prenatally
give on condition that children with FASD can have:
fetal alcohol syndrome (FAS): small widely spaced eyes, missing ridges under nose, thin upper lip
est-ce qu’il y a une différence observée chez les enfants de e mères identifiées comme buveuses légères ou occasionnelles pendant leur grossesse ou chez les mères qui se sont abstenues de boire?
non, pas de différence
but, the most prudent recommendation is to avoid alcohol use completely throughout pregnancy.
The effects of alcohol on the developing infant are numerous, including
damage to internal organs(resulting in heart or kidney problems as well as issues with vision or hearing),
altered physical characteristics (reduced head size, below-average height, and a smooth patch of skin between the nose and the upper lip, a thin upper lip, small widely spaced eyes)
cognitive impairments (problems with hyperactivity and inattention, reduced intelligence, and challenges in school).
Which of the following is a sleeper effect?
explain
a
A newborn infant experiences increased irritability shortly after birth as a result of prenatal exposure to illegal drugs.
b
Seemingly for the first time, a child experiences difficulty concentrating in class, potentially as a result of prenatal exposure to alcohol.
c
A newborn experiences low birth weight as a result of cigarette exposure in utero.
d
An infant is born with shortened limbs as a result of prenatal exposure to thalidomide.
b
Seemingly for the first time, a child experiences difficulty concentrating in class, potentially as a result of prenatal exposure to alcohol.
Sleeper effects are those that take a while to manifest. Sleeper effects won’t be obvious at birth. The sleeper effects may show up years after birth.
which prescription medication was usen during the 1960s to elp alleviate the symptoms of morning sickness experienced by pregnant women?
Thalidomide
the effect of thalidomide on pregnant women and at which period of prenatal development, this medication was given to these women?
and the impacts on infants that received this medication during the embryo period were….
The drug was effective at reducing sensations of nausea in pregnant women, and not negative effect on the pregnant women
during the period of the embryo
infants who had been exposed to the drug prenatally were born with shortened or otherwise malformed limbs, without limbs too
how is transmitted the Zika virus?
is transmitted to humans by mosquitoes or through sexual contact with an infected individual,
what impact has Zika virus on the baby?
microcephaly, or smaller infant head sizes
symptoms of zika virus on women? but for their infants?
Zika infection results in mild symptoms for pregnant women, including a rash, itchy skin, and joint pain, but can result in significant adverse outcomes for their developing infants
the abnormalities found in infants because of the zika virus were found at which period of prenatal development?
The abnormalities in fetal development were found regardless of the time during gestation at which pregnant women were identified as having the Zika virus, not just during the period of the embryo
what is stillbirth?
is the death or loss of a baby before or during delivery. Both miscarriage and stillbirth describe pregnancy loss, but they differ according to when the loss occurs
Which of the following is not an outcome associated with prenatal exposure to Zika?
a
Stillbirth
b
Stunted limb growth
c
Altered brain development
d
Microcephaly
b
Stunted limb growth
zika virus is transmitted by which mosquitoes?
aedes aegypti
microencephalie can be caused by:
genetics, malnutrition, alcohol, zika virus
Which of the following statements concerning Zika prevention is true? explain
a
Pregnant women should avoid travel to areas of the world where Zika transmission has occurred.
b
Almost everyone is immune to the negative effects of Zika, so there is no need to be concerned about preventing it.
c
Condoms cannot be used to reduce the likelihood of sexually transmitting Zika.
d
Pregnant women do not have to worry about contracting Zika virus from mosquitoes in the United States, as Zika has not been transmitted to humans by mosquitoes in this part of the world.
a
Pregnant women should avoid travel to areas of the world where Zika transmission has occurred.
explanation: People can transmit the Zika virus through sexual contact after being bitten by an infected mosquito, and mothers and embryos are susceptible to the Zika virus. People should avoid exposure to the Zika virus, especially in places with confirmed cases of the virus: like the united states in south Florida, Brownsville, texas
examples of teratogens that you learned more about in this course?
Alcohol
zika virus
thalidomide
covid-19
afraid that babies would contract covid from the vagina of the mother, the babies were born by Cesarean section. so were the tested fluids or in maternal breastmilk found the covid?
non
but “there are reasonable concerns that COVID-19 could be contracted in the womb
Which of the following statements regarding associations about the COVID-19 virus, pregnancy, and childbirth is true?
a
Pregnant individuals or those who are considering becoming pregnant during the pandemic should not worry about the impact COVID-19 may have on them or their developing infant.
b
Pregnant individuals or those who are considering becoming pregnant during the pandemic should not consult with medical professionals about the most recent research.
c
One small study revealed no evidence to indicate that COVID-19 was transmitted from mothers to infants who were born by Cesarean section.
d
Studies conclusively indicate that COVID-19 is not passed from mothers to their infants during childbirth.
c
One small study revealed no evidence to indicate that COVID-19 was transmitted from mothers to infants who were born by Cesearean section.
the babies that contracted zika virus have what kind of symptoms:
microencephally,
have severe learning disabilities
development delays
etc.
apparent advances in child in the three years old, in the domain of
motor development(control muscles, walking)
language development
cognitive development(log term memory for past events by 20 months of age)
social development (personal connection, or attachments to their primary caregiver over the first 2 years of life).
cognitive development refers to what?
refers to how the brain develops and how we gain cognitive skills such as information processing, problem solving, language learning, and more.
which scientists did research on cognitive development in this course?
jean Piaget
Lev Vygotsky
Piaget believed in what based on the cognitive development of children?
2 theories of Piaget
Piaget believed that children are active contributors to their own learning—that is, they construct their own knowledge—and for this reason, his theoretical perspective is described as constructivist.
Piaget stated that the growth of cognitive structures occurs when individuals encounter conflicting information that alters their existing perspectives on the world.
Piaget suggests that encountering conflicting information in the world is one of the ways in which
cognitive change occurs over time.
Piaget indicated that the modification of cognitive structures occurred through process known as
assimilation, accommodation, equilibration
what means assimilation selon Piaget?
occurs when individuals encounter information that is similar to what they have in their existing cognitive structures; when this new information is encountered, it is added to existing cognitive structures.
what means accommodation?
a child creates a new cognitive structure to account for information that does not fit elsewhere.
what happens when it is a disequilibration and equilibration ?
when what exists in the outside world is not represented in the created cognitive structures—cognitive structures must be modified through assimilation or accommodation so that greater agreement occurs and equilibration is maintained.
A young child is fascinated with animals and, as a result, enjoys going to the zoo. While at the zoo, she encounters the duck-billed platypus, an interesting mammal that bears some physical similarity to a duck and also lays eggs. The child includes this new animal in her existing schema for ducks. Which of the following cognitive processes did this child use to classify the platypus? explain
a
Equilibration
b
Accommodation
c
Disequilibration
d
Assimilation
d
Assimilation
Explanation
The platypus is all new information, and the platypus is categorized in an already-existing category, which is assimilation. Had the platypus been organized into a new category, that would be evidence for accommodation.
As children’s cognitive structures are established and evolve, children progress through four major stages of cognitive development, three of which occur during infancy and childhood which are:
sensorimotor
preoperational
concrete operational
formal operational
sensorimotor
the age
significant characteristics
0-2 years
learns about the world largely through motor abilities
preoperational
the age
significant characteristics
2-7 years old
can mentally represent the past, but experience issues with animism and egocentrism; routinely fails at conservation tasks
what is animism and egocentrism?
Animism: the child thinks the animal is real, the phone has a soul, you can talk to it.
Egocentrism: they can’t really think about anyone other than themselves. They can’t share another person’s point of view.
what is animism and egocentrism?
Animism: the child thinks the animal is real, the phone has a soul, you can talk to it. –when preschool children ascribe life-like properties to things that are not alive
Egocentrism: they can’t really think about anyone other than themselves. They can’t share another person’s point of view.
formal operational
the age
significant characteristics
able to think and reason about hypothetical situations and/or abstract problems
the formal operational period occurs in adolescence at the earliest, but may never be achieved by some individuals.
