Chapter 11 Flashcards
Zygote
Microscopic mass of multiplying cells that migrates along the mother’s fallopian tube into the uterine cavity. Germinal stage
Germinal Stage
First phase of prenatal development, first two weeks after conception
When does the zygote implant in the uterine wall?
Day 7
When does the placenta form?
During the implantation process
What is the placenta?
A structure that allows oxygen and nutrients to pass into the fetus from the mother’s bloodstream and bodily wastes to pass out to the mother
When is the embryonic stage?
Week two until the second month
What happens in the embryonic stage?
Vital organs and body systems begin to form. Arms, legs, limbs, feet, toes, ears are discernible
When is the fetal stage?
Two months-birth
What happens in the fetal stage?
Rapid bodily growth, as muscles and bones begin to form in the first two months. Organs continue to grow and begin to function. Brain cells multiply, a layer of fat is deposited under the skin for insulation, and the respiratory and digestive systems mature
What happens at week 24 of pregnancy?
Eyes open, facial and auditory senses become operational
What does FOAD mean?
Fetal origin of adult disease
Events during prenatal development can cause vulnerabilities decades later such as heart disease, hypertension, obesity, etc.
What is maturation in relation to child development?
Development that reflects the unfolding of one’s genetic blueprint
What are developmental norms and what is a big example?
Typical age at which individuals display various behaviors and abilities.
Walking happens at around a year
What is the behaviorist theory of attachment?
Develops because mothers are associated with the reinforcing event of being fed
How did Harry Harlow contribute to the theory of attachment?
Studies of attachment in infant rhesus monkeys on the importance of touch to attachment
What is the secure attachment pattern?
Infants play and explore with mother present, become upset when mother leaves, quickly calmed by their return
What is the anxious-ambivalent attachment pattern?
Infants are anxious even when mother is present, protest when they leave, not comforted when they return
What is the avoidance attachment pattern?
Infants seek little contact with their mothers, often are not distressed when they leave
What is Erikson’s stage theory?
Each of the eight stages brings a psychosocial crisis involving transitions in important social relationships
What is Piaget’s stage theory?
The sensorimotor period lasts from birth to about age 2. A child develops the ability to coordinate sensory input with motor actions. Object permanence develops when a child recognizes that objects continue to exist even when they are no longer visible
What is the preoperational period?
Ages 2-7
Conservation: Awareness that physical quantities remain constant
Concentration: Ability to focus on just one feature
Irreversibility: Inability to envision reversing an action
Egocentrism: Limited ability to share another person’s point of view
Animism: Belief that all things are living
What is the concrete operational period?
ages 7-11
Child can perform operations only on images of tangible objects and events. Gradual mastery of conservation
What is the formal operations period?
Begins around age 11
Final stage
Begin to enjoy abstract concepts in addition to concrete concepts
