Chapter 5 - Human Development Flashcards
Germinal stage
The first prenatal stage of development which begins at conception and lasts two weeks.
Zygote
The single cell that results win a sperm fertilizers an egg.
Embryo
A developing Organism from two weeks until about eight weeks after conception
Embryonic stage
The second prenatal stage from two weeks to eight weeks after conception, When all of the major organs form.
Fetal stage
The third prenatal stage, which begins with the formation of bone cells eight weeks after conception and ends at birth.
Neural migration
The movement of neurons from one part of the fetal brain to there more permanent destination; occurs during months 3-5 of the fetal stage.
Prenatal programming
The process by which events in the room alter the development of physical and psychological health.
Teratogens
Substances that can disrupt normal prenatal development and cause lifelong Deficits.
Fetal alcohol spectrum disorder (FASD)
A consequence of prenatal alcohol exposure that causes multiple problems, notably brain damage.
Temperament
The biologically based tendency to behave in particular ways from very early in life.
Personality
The unique and relatively enduring set of behaviors, feelings, thoughts, and motives that characterize an individual.
Life before birth is commonly divided into three distinct stages: the \_\_\_\_\_\_\_\_\_\_\_\_, embryonic, and fetal stages. A. Gestational B. Seminal C. Germinal D. Cellular
C. Germinal
How can researchers tell which sounds a fetus prefers to hear?
A. By measuring the position of the fetus in the womb
B. By measuring changes in fetal heart rate in response to sounds
C. By taking a reading of fetal respiration
D. It is not possible to measure fetal preferences
Be. By measuring changes in the fetal heart rate in response to sounds
Teratogens are
A. Substances that can cause birth defects.
B. Genes that turn on or off with exposure to viruses.
C. Inborn fetal taste preferences.
D. Factors that influence the generation of fetal brain tissue.
A. Substances that can cause birth defects.
Pruning
The degradation of synapses and dying off of neurons that are not strengthened by experience.
Sensorimotor stage
Piaget’s first stage of cognitive development (ages 0-2), When infants learn about the world by using their senses and by moving their bodies.
Object permanence
The ability to realize that objects still exist when they are not being sensed.
Preoperational stage
The second major stage of cognitive development (ages 2-5), Which begins with the emergence of symbolic thought.
Animistic thinking
I believe that inanimate objects are alive.
Egocentrism
Viewing the world from one’s own perspective and not being capable of seeing things from other person‘s perspective.
Conservation
Recognition that when some properties (such as shape) of an object to change, other properties (such as volume) remain constant.
Concrete operational stage
Piagets third stage of cognitive development, which spans ages 6–11, During which the child can perform mental operations – such as reversing – on real objects or events.
Formal operational stage
Piaget’s final stage of cognitive development, from age 11 or 12 on through adulthood, when formal logic is possible.
Zone of proximal development
The distance between what a child can learn alone and what that child can learn assisted by someone else, usually an adult.
