Developmental Psychology Flashcards
cross-sectional study
uses participants of different ages to compare how certain variables may change over life span; can produce quick results
longitudinal study
research that takes period over long period of time; studies one group of participants steadily
teratogens
chemicals or agents that cause harm if ingested or contracted by the mother during pregnancy
placenta
filters out potentially harmful substances; yet teratogens pass through this barrier and affect fetus
fetal alcohol syndrome
children of alcoholic mothers who drink during pregnancy; may result in malformed skills or mental retardation
fetal alcohol effect
moderate drinking during pregnancy, and children may have specific developmental/behavioral problems or learning disabilities later in life
rooting reflex
when touched on the cheek, a baby will turn their head to the side where they felt the touch and seek to put the object into their mouths
sucking reflex
when object is placed into baby’s mouth, the infant will suck on it
grasping reflex
if an object is placed into a baby’s palm or foot pad, the baby will try to grasp the object with their fingers or toes
moro reflex
when startled, a baby will fling their limbs out and quickly retract them to make themselves as small as possible
babinski reflex
when a baby’s foot is stroke, they will spread out their toes
Who was Konrad Lorenz and what did he discover?
he established that infant animals (geese) imprint on individuals that they see during a critical time period. This proves that the early stages of baby’s environment is important for the relationship between parent and child. This is also called attachment.
Who was Mary Ainsworth and what did she discover?
she researched the idea of attachment by placing infants into new situations. She recorded their actions and categorized them into three, broad categories
secure attachment
(66% of babies) infants confidently explore new environment when parents are present, are distressed when they leave, and come back to the parents when they return
avoidant attachment
(21% of babies) resist being held by parents and explore new environment and do not return parents for comfort
anxious attachments
(12% of babies) show extreme stress when parents leave but resist being comforted by them when they return
authoritarian parents
set strict standards for children’s behaviors and apply punishment for violations of these rules
permissive parents
do not set clear guidelines for children or rules are constantly changing
authoritative parents
have set, consistent standards for children’s behavior; but standards are reasonable and explained
What is the difference between continuity and discontinuity?
People who grow continually grow at a steady rate; discontinuously is where there are periods of both rapid development and some of little change
