Chapter 5 - Developing through the life span Flashcards
What does development psychology examine, and what three major issues does it focus on?
Development psychology examines the physical, cognitive, and social change throughout the lifespan, and the three major issues it focuses on are nature and nurture, continuity and stages, and stability and change.
Define a Zygote.
A zygote is a fertilized egg; it enters a 2-week period developing into an embryo.
Define an embryo.
the developing human organism after the two-week to the second month - it’s when the heartbeat starts and when limbs and body parts begin to form.
When does a fetus begin to form?
A fetus begins to form at around nine-weeks to being born.
Developmental researchers who emphasize learning and experience are supporting ______ ; those who emphasize biological maturation are supporting ______.
Continuity and stages
The first two weeks of prenatal development is the period of the _____. The period of the _____ lasts from 9 weeks after conception until birth. The time between those two prenatal periods is considered the period of the ______.
Zygote, fetus, and embryo.
What is a teratogen? and what does it do?
A teratogen is a chemical or virus that can cause harm to the embryo or fetus during prenatal development.
What is fetal alcohol syndrome, and what are the side affects?
Fetal alcohol syndrome is an abnormality in children’s physical and cognitive traits. It is caused when a mother drinks heavily during her pregnancy. Signs in severe cases include a small, out-of-proportion head and abnormal facial features.
What is Habituation, and what is an example?
Habituation is a decrease in responding to repeated stimulation. For example, when children receive a continuous stimulus, their interest begins to fade.
Infants’ ____ to repeated stimulation helps developmental psychologists study what they can learn and remember.
Habituation
Chemicals that the placenta isn’t able to screen out that can harm an embryo or fetus are called ____.
teratogen
The biological growth process, called ____ , explains why most children begin walking by about 12 to 15 months.
Maturation
Define cognition.
Cognition is all the mental processes: thinking, knowing, remembering, and communicating.
What is a schema, and give an example.
A schema is a concept or framework that organizes and interprets information. For example, people had a schema for marriages as a male and female uniting with one another, now same-sex marriage is normal. ( a mental mold of how we view things from our experiences)
Define assimilation and how it relates to schemas.
Assimilation is how we interpret our new experiences in terms of our existing schemas. An example would be when a child sees a baseball for the first time and associates it with other balls.
Define accommodation. Give an example.
Accommodation is the adaptation of our current schemas to incorporate new information. E.g. A child that understands a four-legged creature is a dog.
What’re Piaget’s four major stages in cognitive development?
Stage 1 - The sensorimotor stage
Stage 2 - The preoperational stage
Stage 3 - The concrete operational stage
Stage 4 - The formal operational stage
What is the sensorimotor stage?
The sensorimotor stage is from birth to nearly two; babies take in information through their senses and actions: looking, hearing, touching, mouthing, and grasping.
What is object permanence, and what is an example?
Object permanence is the awareness that things exist, even when they aren’t visible. For example, if you hide a toy in front of a baby, it will search for it for a few seconds because the baby “knows” it’s there - object permanence forms at around eight months old.
What is the preoperational stage in cognitive development?
The preoperational stage occurs around 2 to seven years old; children can represent things with words and images; however, they are still too young to perform mental operations.
What is an example of a children’s conservation?
Conservation is the principle that quantity and volume remain the same, even if there are changes in shape and form.
What is egocentrism?
Looking at things a particular way and having difficulties viewing them another way - preschool children are egocentric.
