What percent of parents report spanking their kids?
25%
How does spanking affect behavior?
It makes behavior worse and effects last longer
What are effective alternatives to spanking?
- Sympathy: children can better cope with the distress
- Finding positive alternatives to expressing their feelings
- Timeouts
What is the turtle technique?
Children feel themselves getting angry they move away from other children and retreat into their “turtle shells”, where they think through the situation until they are ready

What do Nativists argue?
children are born with an innate ability to organize laws of language
What do Empiricists argue?
all learning comes from only experience and observation
What were Plato and Aristotle particulary interested in?
- How children are influenced by their nature and by the nature they receive
- The long-term welfare of society depended on proper raising of children
Why did Plato view the rearing of boys as a particular challenge?
They are the craftiest, most mischievous, and unruliest of brutes
What did Plato emphasize as the most important goals of education?
Self-control and discipline
Aristotle agreed with Plato that discipline was necessary but he was more concerned with…
fitting child rearing to the needs of the individual child gives the child a better chance of receiving treatment that suits him
How did Plato believe children acquired knowledge?
Children have innate knowledge
What did Aristotle believe children acquired knowledge?
Knowledge comes from experience and the mind of an infant is like a clean blackboard
How does Locke view children?
As a Tabula Rose, a blank slate, whose development reflects the nurture provided by the child’s parents and society, and the most important goal is the growth of character
How does one build a child’s character?
Set good examples of honesty, stability, and gentleness, and avoid indulging the child
What did Locke believe once discipline and reason had been instilled in the child?
Authority should be relaxed as fast as their age, discretion, and good behavior could allow it
The sooner you treat him as a man, the sooner he will begin to be one
What does Rosseau believe that parents and society should give children?
Maximum freedom from the beginning
How do children learn according to Rousseau?
From spontaneous interactions with objects and other people, rather than parents or teachers

What did the study of adopted children and schizophrenia indicate?
Children whose birth parent was schizophrenic and who got adopted into a troubled family
Genome
person’s complete set of hereditary information, DNA, and all of its genes
What does a genome influence
behaviors and experiences
Epigenetic
- The study of stable changes in gene expression that are mediated by the environment
- How experience gets under the skin

Methylation
A biochemical process that influences behavior by suppressing gene activity and expression (stress)
If the mother carried more stress during their childs infancy it…
related to the amount of methylation in children’s genomes 15 years later
Increased Methylation in the cord-blood DNA of newborns of depressed mothers/adults who were abused led researchers to speculate…
children are at a higher risk for depression as adults

How does correlation and causation differ?
Correlation indicates the degree to which two variables are associated
Causation indicates that changing the value of one variable will change the value of the other

reproductive cells- egg and sperm- that contain only half the genetic material of all other cells in the body
Meiosis
cell division that produces gametes
Conception
union of egg and sperm- fertilization
Zygote
a fertilized egg cell
What are the four developmental processes that transform a zygote from embryo to fetus?
Mitosis: cell division resulting in two identical daughter cells
Cell Migration: newly formed cells move away from the point of origin
Cell differentiation: cells start to specialize in structure and function
Apoptosis: genetically programmed cell death
Fetal hand plate
The role of apoptosis is seen in the development of the hand which requires the death of the cells between the ridges of the hand plate for the fingers to separate
What happens in trimester 1 week 1 of Prenatal Development
Zygote travels from the fallopian tube to the womb and embeds in the uterine lining
What happens in trimester 1 weeks 2-3 of Prenatal Development
The embryo forms three layers, which become the nervous system and skin, muscles, bones, circulatory system, digestive system, lungs, and glands, the neural tube develops
What happens in trimester 1 week 4 of Prenatal Development
Neural tube continues to develop into the brain and spinal cord; the primitive heart is visible, as are leg and arm buds

Neural Tube
a groove formed in the top layer of differentiated cells in the embryo that eventually becomes the brain and spinal cord
Amniotic sac
a transparent, fluid-filled membrane that surrounds and protects the fetus
Placenta
a support organ for the fetus that permits the exchange of materials carried in the bloodstreams of the fetus and the mother
Protects embryo from dangerous toxins
