Human Development Flashcards
Development
age related intellectual, physical, emotional, and personal changes that occur throughout the life span
What do development theorists allude to?
interaction
What are the 3 stages of prenatal development?
Germinal Period: conception to implantation on the wall of the uterus (approx. 2 weeks)
Embryonic Period: Implantation to the 8th week, arms, legs, gingers, toes and a distinctive heartbeat appear. Starts to develop sexual characteristics
Fetal Period: 9th week to birth; develops functional organ system and increases in body size
What is a zygote?
Fertilized human egg. Contains 23 chromosomes from both the mother and father
What is a teratogen?
and environmental agent that can potentially damage the developing fetus.
Why does experience matter for the new born fetus?
To allow its neuronal connections to fully mature and refine it’s internal communication network
What is Puberty?
period during which a person reaches sexual maturity
Menopause
Time during which a woman’s menstrual cycles slows down and finally stops. (around the age of 50)
What is neuroplasticity?
the brain’s ability to change and adjust it’s connections
Dementia
physically based losses in mental functioning (pathological aging)
What capabilities do babies possess that are used to understand their level of mental development?
(1) They show preferences (to one stimuli or another)
(2) They notice novelty (new things in the environment)
(3) They can learn to repeat activities in response to reward
What is the preference technique?
Two stimuli are presented simultaneously and the researcher records which one the baby looks at longer
Habituation
decline in responsiveness to repeated stimuli - used to access perceptual abilities (and to understand how they remember their worlds)
Reward Techniques
Reward a simple motor movement to see if they baby learns that if they perform that movement they can get a reward for it (kicking leg and mobile)
What are schemas?
Mental model of the world that people use to guide and interpret their experiences - this is part of Piaget’s theory that we are all born with a natural tendency to organize the world
Where does much of what we know about development of thought processes during childhood come from?
Jean Piaget
What does Piaget argue is the governing process of building our mental models of the world as we age?
Assimilation: people fit or assimilate new experiences into existing schemas
Accommodation: Process through which people change existing schema to accommodate new experiences
What are Piaget’s 4 stages or developmental periods?
Sensorimotor, preoperational, concrete operational, formal operational
Sensorimotor Period
birth - 2: schemas revolve around sensory and motor abilities
Object Permanence
Ability to recognize that an object still exists even when you are no longer looking at it
