Exam 3 Flashcards
Developmental psychology
Studies physical, cognitive, and social development throughout life.
Cross-sectional studies
Comparing people of different ages.
Longitudinal studies
Following one group of people or one person over time.
People who emphasize experience and learning
View development as slow and continuous
People who emphasize biological maturation
View development as a sequence of genetically predisposed stages. Everyone passes through stages in same order.
Jean Piaget (Psych type)
Cognitive development
Schemas
Mental representations of the world
Assimilation Schemas
Fitting new info into existing schemas
Accommodation Schemas
Modifying existing schemas to fit new info
Latent learning
Learning with no reinforcement or punishment
Sensorimotor stage
Birth to two years
Child doesn’t understand object permanence–>Starts to understand ~7mo–>Separation anxiety
- Separation anxiety peaks at 13mo
- Peek a boo
Object permanence
Objects exist even when out of view. Can lead to separation anxiety
Preoperational stage
Two years to six years
Understands words can symbolize things
(Contrary to Piaget three year olds can use model to do real thing. Piaget thought it happened later)
Egocentrism
Doesn’t understand conservation
Hide and seek
Pretend play
Egocentrism
Child believes that their perceptions are the same as everyone else’s
Present in pre-operational stage
Conservation
Understanding that an object can change shape without changing what the object is
Child in preoperational stage doesn’t understand it
Child in concrete operational stage does understand it
Concrete operational stage
Seven years to eleven years
- Begins when the child understands
conservation and is no longer
egocentric - Can think like adults but cannot
think abstractly - Learning to comprehend mathematical transformations
Formal operations stage
Twelve years and up
Able to reason on a logical hypothetical level
Abstract logic
Maturing moral reasoning
Temperament (definition)
Emotional reactivity and intensity
Temperament
- Heredity affects temperament
- Temperament affects attachment style
- Persists overtime (Most reactive newborns tend to be most reactive 9 month olds)
Prenatal development
Time from conception to birth
Germinal stage (Time)
Conception to two weeks
Germinal stage
- Zygote
- Cell division, mitosis
- Ends when the zygote implants in the uterine wall ~10 days
Embryonic stage (Time)
3-9 weeks
Embryonic stage
- Inner cells become embryo, outer cells become placenta
- Arms, legs, and tail start to develop
- Heart begins to beat
8 weeks = ~1 inch long
Fetal stage (Time)
9 weeks to birth
Fetal stage
- Cartilage in bones starts to harden
- Much growth of internal organs
- Fetus can squirm and kick
- Organs (such as stomach) develop fast enough so if the baby is born prematurely it will live
- Environmental factors affect development (~6mo fetus is responsive to sounds)
Fetal Alcohol Syndrome
- Facial and limb abnormalities
- Premature birth
- Intellectual disability
- Lower birth weight
- Small head circumference→Smaller brain
Effects of prematurity and low birth weight
- Increased risk of learning disabilities, cerebral palsy, ADHD, autism, dyslexia
- Hospital costs are higher
Brain (General)
- Born with 86 million neurons (Few connections when born)
- Areas underlying memory (hippocampus, frontal lobes) continue to mature during and after adolescence
Brain: Infancy
- Axons grow longer
- Connections grow
- Connections used are strengthened, those not used, shrink
- Infantile amnesia, but can still unconsciously learn
Brain: Early childhood
- Ages 3-6, most rapid brain growth in frontal lobes (rational planning)
- Traces of forgotten childhood languages may persist
- Association areas are the last cortical areas to develop
Brain: Late adulthood
- Longer reaction time (Can lead to inc in fatal accidents)
- Memory, diminishes
- Some impulsivity returns to frontal lobes (May be blunt or inappropriate)
- Amygdala responds less actively to negative events
- Brain-wave reactions to negative images diminish with age
Physical skills: Infancy
- Able to lift head on its own
- 5.5 months sit on their own
- 10 months crawling
- 12 months walking
- Depends on what season child is born in (Born in winter - learn to crawl and walk slower bc more clothes in the way. Born in summer - learn to crawl and walk faster bc less clothes)
- Skills cannot be done before necessary muscular and neural maturation (Bowel and bladder control. Nurture can speed up/slow down necessary muscular and neural maturation)
Piaget (Type Psych)
Cognitive development
Piaget (General)
- Intellectual progression reflects an unceasing struggle to make sense of our experiences
- Brain builds schemas: Concepts or mental molds where we sort our experiences
- Assimilation
- Accommodation
Piaget Stages and Ages
Sensorimotor stage (Birth-2 years)
Preoperational stage (2-6 years)
Concrete operational stage (7-11 years)
Formal operations stage (12+ years)
End of history illusion
How social attitudes change
People believe they have changed but will change little in the future
Theory of Mind
People’s ideas about their own and others’ mental states
Gradually develops
Early childhood
- Understands others emotions
- Begins to empathize
- Begins to learn how to persuade
- Learns that others may hold false beliefs
- Autism spectrum disorder
Early adulthood
- Peak of some types of learning and
memory
Late adulthood
- Troubles recalling words but number of
words recognized is stable w age
- More often experience tip-of-the-tongue
forgetting
All adulthood
- More education earlier in life predicts
better cognitive ability late in life
Autism spectrum disorder
Difficulty understanding that another’s state of mind differs from their own
Secure attachment
In mother’s presence they play comfortably. Still distressed when she leaves. Comforted when she returns.
Insecure attachment
Will not play comfortably in mother’s presence. Distressed when she leaves. Not comforted when she returns.
Mary Ainsworth (Study)
Had mothers and their young children come into the room. Mother leaves. Stranger comes in. Stranger leaves. Mother comes back in.
Mary Ainsworth (Styles of attachment)
Secure attachment
Ambivalent/resistant attachment
Disorganized attachment
Avoidant attachment
Secure attachment Mary Ainsworth
- Warm and affectionate mothers that respond to children when they cry
- Children grow up to be more sociable, competent, better with relationships, than those with insecure
- Children remember more positive things.
Ambivalent (resistant) attachment
Children give mixed messages about their relationship.
Disorganized attachment
- Children didn’t know how to respond. Holding their bodies in odd postures.
- Studies suggest this is due to abuse.
- Mothers have been inconsistent in their responses.
Avoidant attachment
- Weakest attachment. Didn’t have much of a relationship with their mother. Didn’t cry when mother left. Not upset when a stranger comes in.
- Mothers didn’t respond to their children.
Authoritarian Parenting
High expectations, no warmth. Sets the rules and expects them to be followed
- Emphasis on obedience to authority
- “Bc I said so”
- Uncommunicative and distant
- Preschool kids with these parents are more socially withdrawn, unhappy, lower performance in school
- Particularly harmful for boys
Authoritative Parenting
High expectations, warm. Set high but realistic standards.
- Parents explain their rules
- Children raised by this are more mature, independent, socially competent, higher academic performance, higher self esteem
Permissive Parenting
No expectations, warm. Make few rules or demands.
- Lets child find out and learn on their own
- Children raised by this are the least mature, are impulsive, lower self esteem, less self reliant
Neglectful Parenting
No expectations, no warmth. Unconcerned and uninvolved.
- Childs have delinquent behavior, earlier substance abuse, earlier sexual activity, etc.
Kohlberg’s stages of moral development
Levels differ in the amount of internalization
Pre-conventional
Conventional
Post-conventional
Pre-conventional
Child bases morality on consequences
