Developmental Psychology (Modules 13-16) Flashcards
Developmental Psychology
The study of how people are continually developing – physically, cognitively and socially from infancy through old age
Three Major Issues in Developmental Psych
- Nature vs. Nurture: How do genetic inheritance (our nature) and experience (the nurture we receive) influence development?
- Continuity vs. Stages: Is development a gradual, continuous process or a sequence of separate stages?
- Stability vs. Change: Do our early personality traits persist through life, or do we become different persons as we age?
Zygote
The fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo
Embryo
The developing human organism from about 2 weeks after fertilization through the second month
Fetus
The developing human organism from 9 weeks after conception to birth
Newborns prefer their mother’s voice to their father’s immediately after birth. Why?
The fetus is responsive to sound and is exposed to the sound of its mother’s muffled voice constantly while in the womb.
Teratogens
Agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
Fetal Alcohol Syndrome
Physical and cognitive abnormalities in children caused by heavy drinking while pregnant
Rooting reflex
When something touches an infant’s cheek, babies turn toward it and open their mouths
Habituation
Decreasing responsiveness with repeated stimulation. More familiarity = waning interest
Maturation
Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience (ex. standing before walking, using nouns before adjectives)
By when do you have most of your brain cells?
Birth
Where is brain growth most rapid from ages 3-6?
Frontal lobes, which enable rational planning
What are the last areas of the brain to develop?
Association areas, responsible for thinking, memory and language
When is the average age of people’s earliest memories?
3.5 years
Who is the most famous developmental psychologist?
Jean Piaget
Cognition
All mental activities associated with thinking, knowing, remembering and communicating
According to Piaget, what is the driving force behind our intellectual progression?
An unceasing struggle to make sense of our experiences
Schemas
Concepts/frameworks that organize and interpret information
Assimilate
Interpreting our new experience in terms of our existing schemas (ex. A moose must be a cow, because cows have four legs.)
Accommodate
Adapting our current understandings (schemas) to incorporate new information (ex. Schema is modified to include “moose.”)
Piaget’s Stages of Cognitive Development
- Sensorimotor Stage
- Pre-operational Stage
- Concrete Operational Stage
- Formal Operational Stage
Sensorimotor Stage
Stage during which infants know the world mostly in terms of their sensory impressions and motor activities
Age Range: Birth - 2 years
Important concepts: Object Permanence
Pre-operational Stage
Stage during which a child learns to use language but does not yet comprehend the mental operations of concrete logic
Age Range: 2 years - 6 or 7 years
Important concepts: Conservation, Symbolic Thinking, Egocentrism, Theory of Mind
Conservation
Those in the pre-operational stage don’t understand conservation, the principle that quantity remains the same despite changes in shape. (Ex. The girl believes the tall, narrow glass has more milk than the shorter glass, but the volume of milk is actually the same.)
Symbolic Thinking
The ability to recognize that representations can act as symbols (Ex. using a model room with a hidden model toy to find a real toy in a real room)
Egocentrism
The pre-operational child’s difficulty to take another’s point of view; lack of sympathy (Ex. “How would YOU feel is she took your toy?”)
Theory of Mind
People’s ideas about their own and others’ mental states – about their feelings, perceptions and thoughts, and the behaviors one might predict
Concrete Operational Stage
Stage during which children gain mental operations that enable them to think logically about concrete events
Age Range: 6 to 7 years - 11 years
Formal Operational Stage
Stage during which people begin to think logically about abstract concepts
Age Range: 12 years - Adulthood
According to Vygotsky, why do children increasingly think in works and use words to solve problems by age 7?
Language provides the building blocks for thinking.
What is the difference between Piaget’s and Vygtosky’s emphasis on children’s cognitive development?
Piaget emphasized that a child’s mind grows through interaction with the physical environment while Vygotsky emphasized that a child’s mind grows through interaction with the social environment.
Stranger Anxiety
Fear of strangers that infants commonly display; marks a new ability to evaluate people as unfamiliar and possibly threatening
Attachment
Emotional tie with another person; young children seek closeness to their caregiver and show distress upon separation
Summarize Harry Harlow’s study of attachment on monkeys.
Monkeys were raised with two artificial “mothers,” one a bare wire cylinder with a bottle, the other wrapped in cloth with no bottle. Despite a lack of food source, the clothed “mother” was preferred over the wired one. This disproved the idea that infants developed attachment to those who satisfied their need for nourishment.
Besides body contact, what else is important in forming an attachment?
One person providing a safe haven when distressed and secure base from which to explore
Critical period
An optimal period shortly after birth when an organism’s exposure to certain stimuli or experiences produces proper development
Lorenz’s imprinting
The process by which certain animals form attachments during a critical period very early in life
