Unit 9: Developmental Psychology Flashcards
developmental psychologist
studies how heredity and the environment influence human development and behavior throughout the lifespan
nature versus nurture
debate on whether heretical factors or environmental factors influence cognition and behavior
X chromosome
sex chromosome found in both genders
Y chromosome
sex chromosome found in males
Zygote
fertilized egg
How do heredity and environments affect development?
Heredity influences development by predisposing organisms to certain traits and behaviors. It is the environment that shapes those behaviors
temperament
natural tendency to think, feel, and behave a specific way
embryo
organism in the embryonic stage of prenatal development
fetal alcohol syndrome (FAS)
when there are high alcohol levels in the baby due to mother’s consumption of alcohol
fetus
organism in the fetal stage of prenatal development
maturation
physical changes and development due to genetic programming
newborn reflexes
involuntary movements that newborns exhibit in responses to stimuli
What can newborn babies do?
Newborns exhibit natural reflexes such as the moro, sucking, grasping, and rooting reflexes
What influences does maturation have on early development?
Maturation facilitates early physical development
autism spectrum disorder
children deficient in communication and social interactions; have specific and repetitive interests
Habituation
decreased responsiveness to repeated stimulation
infantile amnesia
inability to recall events preceding age three
Jean Piaget’s cognitive developmental theory
theory of cognitive development emphasizing physical experiences and interactions
Schemata
concepts formed from experiences
Assimilation
interpretation of new experiences using current schemas
accommodation
combining of new experiences with personal schemas
sensorimotor stage
(ages 0-2) when children explore the world using senses and actions
object permanence
awareness that things continue to exist even when not perceived
preoperational stage
(ages 2- 6 or 7) can represent things with words and images (symbolic thinking) and use intuition but not logical reasoning
Egocentric
inability to see others’ points of view
concrete operations
(ages 6 or 7 - 11) use logical thinking and understand basic arithmetic
concepts of conservation
ability to understand that change in form does not mean change in quantity
formal operations
(ages 12 and up) can use abstract reasoning
Metacognition
ability to be conscious of and be able to control one’s cognitive processes
Teratogens
harmful substances that embryo or fetus can be exposed to during prenatal development
theory of mind
ability to understand others’ mental states and points of view
Vygotsky’s zone of proximal development
things that a learner can accomplish with help from others
Jean Piaget
a very influential french psychologist who developed a theory for how cognitive development occurs- through physical experiences
Lev Vygotsky
a very influential Russian psychologist who developed an opposing theory to Piaget’s for how cognitive development occurs- through social interactions
Attachment
close emotional bond between two people
authoritarian parents
impose rules and expect obedience without question
authoritative parents
expect mature behavior, explain why rules must be followed, and negotiates with children about rules and boundaries
Erik Erikson’s psychosocial theory of development
8 stages that describe crises that an individual must overcome in their lifetime to psychosocially develop
trust versus mistrust
must determine whether to trust or not trust people (0-2)
autonomy versus shame and doubt
develop independence and responsibility (2-3)
initiative versus guilt
try to control one’s behavior (3-6)
industry versus inferiority
try to develop good social skills (6-puberty)
identity versus role confusion
try to figure out who one is (adolescence)
intimacy versus isolation
try to develop intimate relationships (early adulthood)
generativity versus stagnation
try to inspire young individuals (middle adulthood)
