Exam 4 Flashcards
prenatal period
stage of development between conception and birth
what are the stages of prenatal development?
- germinal
- embryonic
- fetal stages
- Germinal Stage
- approx. 2 weeks
- conception to implantation
- zygote and mitosis (cell division)
- ends when blastocyst implants on the uterine wall
zygote
a single-celled fertilized egg
What are the 3 crucial structures needed after implantation
- Aminotic sac w/ amniotic fluid
- Placenta
- Umbilical Cord
Amniotic sac filled w/ amniotic fluid
- regulates the exchange of fluids
- cushions against environmental changes
Placenta
- passes oxygen and nutrients from parent to embryo
blastocyst
a bundle of cells
teratogens
(chemicals, viruses) that can cause harm to prenatal organisms
Umbilical cord
tube w/ blood vessels that carry blood between embryo/fetus and placenta
- Embryonic stage
- weeks 3-8
- called an embryo
- all major organ systems are formed
- sexual differentiation begins
- miscarriages are most common in this stage
- Fetal stage
- from month 2 to birth
- called a fetus
- rapid growth occurs
- organ systems mature
- development of senses + brain
case study
collection of information from one individual in order to better understand physical and psychological changes over the lifespan
survey
researcher asks individuals to self-report important information about their thoughts, experiences, and beliefs
naturalistic observation
observing behavior in its natural context
experiment
involves manipulating variables to identify cause-and-effect relationships between them
developmental norms
what average age should children hit a developmental milestone?
biological milestones - are they universal?
ex. walking, talking, and puberty
+++ ARE universal +++
social milestones - are they universal?
ex. age when children begin school
+++ NOT universal +++
Theory of continuous development
views development as a cumulative process, gradually building on and improving existing skills
Theory of discontinuous development
view development as occurring in “unique” stages - where major changes occur that make someone behave differently than before
what two things shape who we become/ mainly children?
nature (biological, genetics) AND nurture (environment, culture)
what effects the achievement gap?
socioeconomic status
Psychosexual theory of development
Freud’s theory states that children’s pleasure-seeking urges are focused on different areas of the body (oral, anal, phallic, latency, and genital)
Psychosocial theory of development
Erik Erikson’s theory that development is social in nature and not sexual
Erikson’s Psychosocial Stages
- Infancy (0-1): trust vs. mistrust (basic needs)
- early childhood (1-3): autonomy vs. shame (independence)
- play age (3-6 years): initiative vs. guilt (unsuccess = guilt)
- school age (7-11): industry vs. inferiority (self-confidence)
- adolescence (12-18): identity vs. confusion
- early adulthood (19-29): intimacy vs. isolation
- middle age (30-64): generativity vs. stagnation (contribute to society and family)
- old age (65+): integrity vs. despair (makes sense of life)
Cognitive theory of development
Jean Piaget’s theory focuses on how thinking and reasoning change as we develop
Sociocultural theory of devleopment
Lev Vygotsky’s theory states that social interaction is a crucial aspect of cognitive development
Physical development is rapid over the first ___ years of life, and then slows down
first 5 YEARS
Temperament (building blocks of personality)
a person’s innate characteristic emotional reactivity and intensity
What are the 3 categories of babies w/ descriptions?
- easy babies: easy to take care of and not emotionally reactive/calm down easily
- slow to warm up babies: negative reactions to change, small intensity of reaction (not a long time)
- difficult babies: incredibly intense reactions that are difficult to calm
Harlow’s Monkeys
monkey got more comfort from cloth monkey as opposed to wire monkey w/ bottle (more like their caregiver)
What are Ainsworth’s Quality of attachment?
- secure attachment
- anxious/ambivalent attachment
- avoidant attachement
secure attachment
- a strong, healthy emotional bond
- most infants
- eager for comfort when caregiver leaves and returns
anxious/ ambivalent/ resistant attachment
- anxious, does not trust a caregiver
- go for comfort when caregiver returns but are frustrated
avoidant attachment
- bond lacks
- when caregiver returns, they dont care
Adolescence
socially constructed time between child and adult
what occurs during physical development in adolescence?
- puberty: sexual maturation
(girls: 10-15, boys: 11-16)
BOYS: menarche (first ejaculation)
GIRLS: first menstrual period
What occurs during the coginitive development of adolescents?
- better at metacognition (thinking about thinking)
Marcia’s Identity Statuses
Crisis (active exploration) vs. No crisis (no active exploration)
AND
Committed (chosen an identity) vs. Not committed (haven’t chosen an identity)
Identity Achievement
have explored and have chosen an identity
Identity Foreclosure
you’ve chosen an identity and have never explored
Identity Moratorium
actively exploring identity and haven’t chosen
Identity Diffusion
haven’t explored an identity and haven’t chosen one
Emerging adulthood
new stage encompasses time period from 18 to complete independence
What physical changes occur during adulthood?
- the peak of physical development occurs in early adulthood and a decline starts in the 30s-40s
- sensory decline in late adulthood
What are the cognitive changes that occur during adulthood?
- ability to stay steady and intelligent increases
- speed of cognitive processing declines in late adulthood
Personality
an individual’s unique collection of consistent behavioral traits
What are the two important parts of personality?
- Unique: differences between people
- Consistent: describing people’s similarities from one situation to the next
Personality trait
relatively stable and enduring tendency to behave in a particular way in a variety of situations
Freud’s psychoanalytic theory
the idea that human behavior is influenced by unconscious drives, particularly sexuality and aggression
What are the three systems interacting in our mind, according to Freud?
Id, Superego, Ego
Id
primitive urges, present from birth
“I want to do that now”
Superego
develops as a child interacts with others, learning whats socially right or wrong
“Its not right to do that”
Ego
- the rational voice, compromising between Id and Superego
“Maybe we can compromise”
Neurosis
tendency to experience negative emotions
