Chapter 3 Flashcards
The scientific study of the changes that occur in people as they age from conception until death
HUMAN DEVELOPMENT
Research design in which one participant or group of participants is studied over a long period of time
LONGITUDINAL DESIGN
Impact on development when a group of people share common time period or life experience
COHORT EFFECT
Research design in which several different age groups of participants are studied at one particular point in time
CROSS-SECTIONAL DESIGN
Research design in which participants are first studied by means of a cross-sectional design but also Followed and assessed for a period of no more than six years
CROSS-SEQUENTIAL DESIGN
The influence of our inherited characteristics on our personality, physical growth, intellectual growth, and social
interactions
NATURE
The influence of the environment on personality, physical growth, intellectual
growth, and social interactions
NURTURE
Focuses on nature vs. nurture
BEHAVIORAL GENETICS
The science of inherited traits
GENETICS
Special molecule that contains the genetic material of the organism
DNA (deoxyribonucleic acid)
Section of DNA having a certain pattern of chemical elements
GENE
2 TYPES OF GENE
DOMINANT AND RECESSIVE
Referring to a gene that actively controls the expression of a trait
DOMIINANT
Referring to a gene that only influences the expression of a trait when paired with an identical gene
RECESSIVE
Tightly wound strand of genetic material or DNA
CHROMOSOMES
What disorder does include Down syndrome, Klinefelter’s syndrome, and Turner’s syndrome
CHROMOSOMES DISORDER
What disorder include PKU, cystic fibrosis, sickle cell anemia, and Tay-Sachs disease
GENETIC DISORDER
the moment at which a female becomes pregnant
CONCEPTION
The female sex cell, or egg
OVUM
The union of the ovum and sperm
FERTILIZATION
Cell resulting from the uniting of the ovum and sperm; divides into many cells, eventually forming the baby
ZYGOTE
Identical twins
– formed when one zygote splits into two separate masses of cells, each of which develops into a separate embryo
MONOZYGOTIC TWINS
Often called fraternal twins
– occur when two eggs get fertilized by two different sperm, resulting in the development of two zygotes in the uterus at the same time
DIZYGOTIC TWINS
PERIODS OF PREGNANCY
- GERMINAL PERIOD
- EMBRYONIC PERIOD
- FETAL PERIOD
Is the name for the developing organism from two weeks to eight weeks after fertilization
EMBRYO
The period from two to eight weeks after fertilization, during which the major organs and structures of the organism develop
EMBRYONIC PERIOD
Times during which certain environmental influences can have an impact on the development of the infant
CRITICAL PERIOD
Any factor that can cause a birth defect
TERATOGEN
The time from about eight weeks after conception until the birth of the child
FETAL PERIOD
Name for the developing organism from eight weeks after fertilization to the birth of the baby
FETUS
The point at which it is possible for an infant to survive outside the womb, usually about 22-26 weeks
VIABILITY
Infants are born with reflexes that help them survive
- GRASPING
- MORO (STARTLE)
- STEPPING
- ROOTING
- SUCKING
Unused synaptic connections and nerve cells are cleared away to make way for functioning connections and cells
SYNAPTIC PRUNING
The development of thinking, problem solving, and memory
COGNITIVE DEVELOPMENT
Developed a four-stage theory of cognitive development based on observation of infants and children
