Q

Werner 1989

A

The Kauai Study, a groundbreaking longitudinal study, spanned over 40 years and focused on the development of 698 children born on the Hawaiian island of Kauai in 1955. This research project aimed to assess the long-term consequences of stressors before, during, and shortly after birth.

when two eggs happen to be released into the fallopian tube at the same time and are fertilized by two different sperm. only have half their genes in common
41
ectopic pregnancy
pregnancy in which fertilized egg are on the outside of the uterus; life threatening
42
neural tube
a groove formed in the top layer of differentiated cells in the embryo that eventually becomes the brain and spinal cord
43
amniotic sac
a transparent, fluid-filled membrane that surrounds and protects the fetus
44
placenta
a support organ for the fetus; it keeps the circulatory systems of the fetus and pregnant parent separate, but a semipermeable membrane permits the exchange of some materials between them (oxygen and nutrients from pregnant parent to fetus, and carbon dioxide and waste products from fetus to pregnant parent)
45
umbilical cord
a tube containing the blood vessels connecting the fetus and placenta
46
cephalocaudal development
the pattern of growth in which areas near the head develop earlier than areas farther from the head
47
Trimester 1 Week 1 Milestones
Zygote travels from fallopian tube to womb and embeds in uterine lining; cells arrange into a ball and begin to form embryo and support system.
48
Trimester 1 Weeks 2-3 Milestones
Embryo forms three layers, which will become the nervous system and skin; muscles, bones, and circulatory system; and digestive system, lungs, and glands; neural tube also develops.
49
Trimester 1 Week 4 Milestones
Embryo forms three layers, which will become the nervous system and skin; muscles, bones, and circulatory system; and digestive system, lungs, and glands; neural tube also develops.
50
Trimester 1 Weeks 5-9 Milestones
Facial features differentiate; rapid brain growth occurs; internal organs form; fingers and toes emerge; sexual differentiation has started.
51
Trimester 1 Weeks 10-12 Milestones
Heart develops its basic adult structures; spine and ribs develop more fully; brain forms major divisions.
52
Trimester 2 Weeks 13-24 Milestones
Lower body growth accelerates; external genitalia are fully developed; body develops hairy outer covering; fetus can make basic facial expressions; fetal movements can be felt by the pregnant parent.
53
Trimester 2 Weeks 25-38 Milestones
Fetus triples in size; brain and lungs are sufficiently developed at 28 weeks to allow survival outside of womb; visual and auditory systems are functional; fetus is capable of learning and behaviors begin to emerge.
54
phylogenetic continuity
humans share many characteristics, behaviors, and developmental processes with nonhuman animals, especially mammals, due to our common evolutionary history
55
habituation
a simple form of learning that involves a decrease in response to repeated or continued stimulation
56
dishabituation
the introduction of a new stimulus rekindles interest following habituation to a repeated stimulus
57

61
FASD
harmful effects of alcohol consumption on a developing fetus, including characteristic facial features, intellectual development disorder, attention changes, and hyperactivity
62
neurons
cells that are specialized for sending and receiving messages between the brain and the other parts of the body, as well as within the brain itself
63
cell body
component of the neuron that contains the basic biological material that keeps neuron functioning
64
dendrite
neural fibers that receive input from other cells and conduct it toward the the cell body in the form of electrical impulses
65
axons
neural fibers that conduct electrical signals from the cell body in the form of electrical impulses
66
synapses
microscopic junctions between the axon terminal of one neuron and the dendritic branches or cell body of another
67

cells in the brain that provide a variety of supportive function form the myelin sheath
68
myelin sheath
fatty sheath that forms around certain axons in the body and increase the speed and efficiency of information transmission
69
cerebral cortex
"gray matter" of the brain, consisting of four distinct lobes
70
occipital lobe
major area of the cortex that is primarily involved in processing visual information
71
parietal lobe
major area of the cortex that is associated with spatial processing and sensory information integration
71
temporal lobe
major area of the cortex that is associated with speech and language, music, and emotional information
72

major area of the cortex that is associated with working memory and cognitive control
73
association areas
major area of the cortex that is associated with working memory and cognitive control

77
neurogenesis
proliferation of neurons through cell division
78
aborization
formation of new dendritic trees and branches
79
spines
formations on the dendrites of neurons that increase the dendrites’ capacity to form connections with other neurons
80
myelination
the formation of myelin (a fatty sheath) around the axons of neurons that speeds and increases information-processing abilities
81
synaptogenesis
the process by which neurons form synapses with other neurons, resulting in trillions of connections
82
synaptic pruning
the normal developmental process through which synapses that are rarely activated are eliminated
83
plasticity
the capacity of the brain to be affected by experience
84
experience-expectant plasticity
the process through which the normal wiring of the brain occurs in part as a result of species-typical experiences (leads to heightened vulnerability) "The downside is heightened vulnerability. If the experience that the developing brain “expects” does not occur, development may be compromised. This phenomenon is exemplified by the classic work of Hubel and Wiesel, who deprived kittens of light exposure in one of their eyes (Hubel & Wiesel, 1962, 1970; Wiesel & Hubel, 1963). When the eye was later reopened, it was functionally blind; the cells that would have normally responded to it had reorganized, responding instead to the eye that had continued to receive visual input."
85
experience-dependent plasticity
the process through which neural connections are created and reorganized throughout life as a function of an individual’s experiences
86
scientific method
