Test 1 Flashcards by Micah Wilson

What are the two main views of child development learning?

Continuous (nature-genetics)- Children stay on the same path through development.

Discontinuous (nurture-epigenetics)
Child change change paths of development anytime

What is the major goal of child-development research?

To understand how heredity and the environment interact to determine development.

Can children influence their own development?

Yes. Children interpret their experiences and often actively influence the experiences that they have. Parent-child relationships are bi-directional.

What does the biological perspective of development suggest?

Two important concepts:
Critical period: Time in which a child is able to learn.
Imprinting: Child forming emotional bond with mother.

What are the two theories within the biological perspective?

Maturational theory- development follows a pre-arranged biological plan

Ethnological theory- behaviours are adaptive because they have survival value.

What is Bandura’s social cognitive theory?

Children develop a sense of self-efficacy through experience and this influences their behaviour.

What are the two types of systematic observations in child development?

Naturalistic observation (in natural environment), and Structured observation (Researchers create a setting to elicit behaviours of interest)

What are the different types of bias in observational studies?

Observer bias (researchers may interpret behaviour a certain way to agree with hypothesis)
Observer influence (participants change behaviour if they know they are being watched)

What is important to remember when picking a sample?

Samples of children who participate in research should be representative of the population of interest

What are qualitative methods?

Qualitative methods allow researchers to investigate children’s thoughts and feelings about a topic of interest

What are the four designs for studying age related changes?

Longitudinal study: the same individuals are tested repeatedly over time
Microgenetic study: children are tested repeatedly over a span of days or weeks
Cross-sectional study: children of different ages are tested at one point of development
Longitudinal-sequential studies are hybrids of longitudinal and cross-sectional studies

What is the period of zygote?

Egg is fertilized in fallopian tube. First 2 weeks. Implants itself it wall of uterus. Placenta formed. Also referred to as a blastocyst (ball of cells).

What is the period of the embryo?

2-8 weeks after fertilization. Cluster of cells where structures and organs begin to form (heartbeat established).

What are the 3 structures that form in embryo?

Amniotic sac (protective bag filled with embryo and amniotic fluid), Placenta (nutrients), and umbilical cord (carries placenta to embryo)

What are late stages of an embryo known as?

Known as Ovum. Conception to 4 weeks. Beginning of development of spinal cord, nervous system, gi tract, heart, and lungs.

What is the period of the fetus?

From 8 weeks to birth. Finishing touches on organs and systems. Muscles + connective tissue begin to be produced.

How often do miscarriages happen?

10-25% of the time. Most common cause is chromosome abnormality. Most occur by week 13. Risk goes up with age.

When does the age of viability occur?

Weeks 22-26

What are the different terminologies within the age of viability period?

Premature: born before due date with low body weight Preterm: born early but has normal body weight Small for date: born close to date but low body weight.

What are risk factors for low body weight of babies?

Maternal drug use. Abnormal structure of uterus Multiple kids Teenage Mom

What is lightening?

fetus drops into lower pelvis, mother more comfortable

What is a Electronic fetal monitor?

device that tracks fetal heartbeat via a monitor attached to the mother’s abdomen or by a wire through the cervix with a sensor on the fetus’s scalp

What are the 3 stages of birth?

1. Multiple contractions and ends when cervix is fully enlarged. lasts many hours 2. Infant exits through birth canal. less than an hour 3. placenta expelled. lasts a few minutes.

What is a Caesarean delivery (c-section)?

Surgical procedural birth when birth is slow or complicated. Cons: Mother at risk of infection, longer recovery period and hospital stay. Infant exposed to maternal medication (but no long term effects)

What is a teratogen?

agent that causes abnormal fetal development

What are some general risk factors toward child development?

Mothers age Poor nutrition Maternal stress Drugs Exposure to multiple risk factors

What are risk factors for sudden infant death syndrome (SIDS)?

Teen pregnancy Little prenatal care Exposure to smoke Sleeping position and overheating

What are risk factors embedded within poverty?

Limited medical care, limited knowledge, poor diet, inadequate living conditions, increased stress

Does timing of a teratogen matter?

Period of Zygote (< 2w)  miscarriage Period of Embryo (2 - 8w)  Most vulnerable time, especially Week 5; major structural abnormalities Period of Fetus (> 8w)  Affects still developing organs (e.g., CNS, genitalia), stunted growth, functional problems (e.g., attention, learning)

Are teratogen sensitivity based on genetics?

Yes

How do some teratogens present themselves?

Either immedialty or extremely delayed

What kinds of things can alcohol do to a fetus?

Arousal: hyperactive, impulsive Poor social skills: aggressive, self abusive Heart defects Head and facial abnormalities: Microcephaly (small head circumference), small eye slits, flat nasal bridge

What is the cerebral cortex?

brain’s wrinkled surface, consists of right and left hemispheres linked by corpus callosum

What are the 3 cortexs?

Sensory, Motor, and Association Cortex

What are the 4 lobes of the brain?

Frontal, temporal, parietal, and occipital.

What is Lateralization?

Prone to use one hemisphere in preference to the other for particular tasks

What does motor development depend on?

Maturation and Motor cortex controls

What does the brain originate from?

Prenatal Neural Plate

What are the two brain cell types?

Glial cells (produce myelin, regulate nutrients, repair tissue damage, and protect neurons) + Neurons (interpret information from world)

What are the neural processes of "Blooming + Pruning"?

1. Blooming (More neurons produced then needed) 2. Neurons grow in size 3. Neurons form connections with other cells (synaptogenesis) 4. Loss of of neural cells is normal (pruning)

What two growth trends do we see in prenatal development?

cephalocaudal (head to foot) and Proximodistal (in to out)

What are mechanisms of healthy growth?

Plenty of sleep and proper nutrition (ideally breast milk)
