Quantitative Research

- How heavily scientists rely on data - many scientists prefer quantitative data as they're easy to work with - con: individual distinctions are lost when data are reduced to numbers

Put the following into order of growth within an embryo: webbed toes, knees, legs, and feet

- Legs - Knees - Feet - Webbed toes

What did Freud believe about the development in the first 6 years of a child's life?

- Occurs in 3 stages - Children derive erotic pleasure from whatever body part is central at each stage

B.F. Skinner

- Psychology should focus on the scientific study of behavior - recognized operant conditioning

Ultrasound

- aka sonogram - an image of a fetus produced by using high frequency sound waves - similar to x rays but uses sound waves rather than radiation

Effects of food insecurity

- directly affects low birthweight - increases chronic illnesses

How did Erikson describe the developmental stages?

- divided into 8 developmental stages

Pavlov

- experiment w/ dogs & drooling at the sound of a bell

Benefits of kangaroo care?

- faster weight gain - less medical complications

Dizygotic (DZ) Twins

- fraternal twins - Twins who are formed when 2 separate ova are fertilized by 2 separate sperm at roughly the same time - DZ twins have about 1/2 of their genes in common

What forms in the middle 3 months (4th-6th mo)?

- heartbeat becomes stronger - digestive & excretory systems, fingernails, toenails, teeth buds, and hair grows - brain becomes 6x bigger and develops new neurons & synapses

Monozygotic (MZ) twins

- identical twins - Twins who originate from 1 zygote that splits apart very early in development. Other monozygotic multiple births (triplets, etc) can occur. - identical genetic instructions for everything affected by genes

Consequences of low birthweight

- later to smile, hold a bottle, walk, and to communicate - cognitive, visual, and hearing impairments - heart disease & diabetes prone as an adult

Hispanic paradox

- low SES correlates with low birthweight - but most babies to immigrants are healthier than those richer and of the same ethnicity

Factors increasing birth complications

- low birthweight/preterm birth - genetic abnormalities - tetrogen exposure - mom is unsually young/old/small/ill

What grows/improves within fetuses during the final 3 months of pregnancy?

- lungs begin to expand & contract as the fetus exercises its breathing muscles by swallowing amniotic fluid - heart valves, arteries, and veins go through a final maturation to prevent bleeding

Correlation

- most common mistake is to believe that correlation = causation as correlations usually does not answer q's - Correlation exists between 2 variables if one variable is more or less likely to occur when the other does - positive if both variables increase/decrease together - negative if one goes up and the other goes down - zero if no connection is evident - many correlations are unexpected

Cross-sectional Research

- most convenient, quickets, and cheapest way to study developmental change overtime - Group of ppl of one age are compared with a similar group of people of another age - does not always reliably indicate the processes of development

Lev Vygotsky

- pioneer of the sociocultural perspective - studied cognitive competencies of ppl of different backgrounds - founder of the sociocultural theory

Maternal malnutrition effects

- slow fetal growth - most likely to have an underweight baby

Longitudinal Research

- to discover whether age itself, not historical trends, causes developmental change - collect data repeatedly on the same individuals great in studying development over many years - need to wait decades for conclusions but waiting can have disastrous consequences

Cognitive Development

-----> 1 of the 3 domains of human development Includes all the mental processes that a person uses to obtain knowledge or to think about the environment Ex: perception, imagination, judgment, memory, education, and language; babies starting to speak to express connections between objects & words

----> 1 of 3 domains of human development Includes development of emotions, temperament, and social skills. Family, friends, the community, the culture, and the larger society are particularly central to the psychosocial domain Ex: Cultural differences in "appropriate" sex roles or in family structures are part of this domain; babies wouldn't have been able to speak unless people talked to the baby

Biosocial Development

---> 1 of the 3 domains of human development Includes all the growth&change that occur in a person's body&the genetic, nutritional, and health factors that affect that growth and change. Ex: motor skills (everything from grasping a rattle to driving a car); babies starting to speak b/c of brain&vocal chords maturation

Why does the mother-child bond intensify during the final 3 months?

Mom is more aware of the fetal size & movement. In turn, mom's sounds, food, and behavior patterns become part of fetal consciousness. --> Auditory communication begins at 28 weeks

Practical Guidance

Selective Adaptation

Process which living creatures adjust to their environment. Genes that enhance survival and reproductive ability are selected, over the generations, to become more prevalent --> basic idea from evolutionary theory --> humans today react in ways that helped survival back in the days

Implantation

Process, beginning after 10 days after conception, in which the developing organism burrows into the placenta that lines the uterus, where it can be nourished and protected as it develops

Similar in the fact that problems as an adult were probably from unresolved conflicts of childhood Different in that Erikson's stages emphasize not sexual urges but family & culture

Gene

Small section of a chromosome - basic unit for the transmission of heredity. A gene consists of a string of chemicals that provide instructions for the cell to manufacture certain proteins

Why must differences among people need to be noted?

So that "all kinds of people" are studied, avoiding the assumption that everyone develops in the same way - Kagan's suggestion

What replaced the idea that both growth is linear and that progress is inevitable

The idea that both continuity and discontinuity are art of every life, that gains and losses are apparent at every age, that changes proceed in many ways `

Difference-equals-deficit Error

The mistaken belief that a deviation from some norm is necessarily inferior to behavior or characteristics that meet the standard; human tendency to notice differences & jump to conclusions that something important is lacking in them - Danger in drawing conclusions based on a limited group as you consider your own "group" as normal and every other group abnormal

Superego

The moral ideal, conscience, learned from parents & society

What did Rogers stress? (humanism)

The need to accept and respect one's own personhood as well as that of everyone else --> people should give each other unconditional positive regard

Conditioning

The process by which responses become linked to particular stimuli - sometimes called Stimulus Response Conditioning

Why can't you say "Which characteristic, behavior, or emotion results from genes and how much from experience?:

The real question is "How much?" However, even that question is wrong since it implies proportions Both genes&the environment affect every characteristic. Nature always affect nurture, and nurture always affect nature.

Developmental application of humanism?

Humanism

Theory that stresses the potential of all humans for good and the belief that all people have the same basic needs, regardless of culture, gender, or background

How did sociocultural perspective change the way contemporary scientists think?

They now consider social context in every study.

Genes elicit responses that shape development does what?

Thus, personality may be partly the cause of a person's experiences, not merely the result

What is the first task of the outer cells (the placenta)?

To achieve implantation aka embed themselves into the uterus --> about 50% of natural conceptions fail over here LOLOLOL

Why are theories needed?

To suggest hypotheses, spur investigation, and to find answers so that empirical evidence can replace untested personal assumptions

What did Abraham Maslow & Carl Rogers believe?

Traditional psychological theories underrated human potention by focusing on evil, not good. --> founded a theory called humanism

True

Cross-Cultural research

Uncovers shared behaviors that ppl are unaware of - Reading book to toddlers. US moms use more nouns than verbs when they read as Chinese moms use more verbs.
