Unit 6: Review Flashcards
Developmental Psychology
A branch of psychology that studies physical, cognitive, and social change throughout the lifespan
Continuity and stages
What parts of development are gradual and what parts are abruptly in separate stages
Stability and change
Which of our traits persist through life? How do we change as we age?
What did Lawrence Kohlberg come up with?
Moral Development
What did Erik Erikson come up with?
Psychological development
What did Jean Piaget come up with?
Cognitive development
Conception
Begins with the release of the egg from the ovary, and 250 million deposited sperm. One sperm penetrates the coating and within hours, they fuse
Germinal stage
First 10-14 days, the zygote undergoes rapid cell division
How does the zygote become an embryo?
After the germinal stage, it attaches to the uterine wall and becomes and embryo from about 37 weeks.
Embryo vs Placenta
The zygote’s inner cells become the embryo and the outer ones become the placenta
Fetal stage
After about 9 weeks, the facial features, hands, and feet form
Teratogens
Agents, such as chemicals or viruses, that can reach the embryo during development and cause harm (Ex. Alcohol)
Fetal Alcohol Syndrome
Lifelong physical and mental abnormalities due to drinking while pregnant
Rooting reflex
The baby turns its head when the corner of its mouth is stroked
Sucking reflex
When the roof of the mouth is stroked, the baby will suck
Grasping reflex
Stroking the palm of a baby’s hand causes it to close its fingers
Startle Reflex
The baby throws back its head and extends and pulls back its arms and legs and cries when it hears a loud sound or sudden movement.
Babinski reflex
Extended toes after the sole of the foot is stroked
Habituation
Decreased responsiveness with repeated stimulation
Maturation
Biological growth process, uninfluenced by experience
Sequence of development for babies
3 months - rolling over
6 months - sitting unsupported
8-9 months - crawling
12 months - beginning to walk
15 months - walking independently
Infantile Amnesia
Cannot create memories before the age of 3
Jean Piaget
Believed that children moved from stage to stage as they matured and were exposed to relevant types of experiences
Schema
Mental mold to which we pour our experiences
Assimilation
Interpreting new information in terms of an existing schema
Accommodation
Changing the existing schema to incorporate new information
Piagets stages of Cognitive Development
Sensorimotor, Preoperational, Concrete Operational, and Formal Operational
Sensorimotor
Experiences the world with their 5 senses. 0-2 years old
Preoperational
Developing language and symbolic thinking. They are egocentric. 2-7 years old
Egocentric
Cannot perceive things from another’s point of view
