Ch. 8 Development Flashcards
1
Q
human development
A
scientific study of the changes that occur in people as they age from conception until death
2
Q
nature vs. nurture
A
heredity, the influence of inherited characteristics on personality, physical growth, intellectual growth, and social interactions VS. the influence of the environment on all of those same things (i.e. parenting styles, physical surroundings, economic factors)
3

diff participants of various ages are compared at one point in time to determine age-related differences
4
Q
longitudinal design
A
same participants are studied at various ages to determine age-related changes
–>cohort effect
5

impact on development that occurs when a group of people share a common time period or common life experience
8
Q
genetics
A
science of heredity
9
Q
DNA
A
molecule containing genetic material, made up of sequences of amines (genes)
10
Q
amines
A
organic structures that contain the genetic codes for building the proteins that make up organic life (hair coloring, muscle, and skin, for example) and that control the life of each cell.
11
Q
chromosomes
A
tightly wound strands of DNA
–> 23 from each parent
–> 22 autosomes determine characteristics, 1 determines gender
12
Q
dominant gene
A
gene that actively controls a trait’s expression
13
Q
recessive gene
A
gene that only influences a trait expression when paired with an identical gene
14
Q

all traits controlled by more than one pair of genes
15
Q
zygote
A
fertilized egg cell that divides into many cells and forms the baby
16
Q
Monozygotic twins
A
formed when the zygote splits into two separate masses of cells, each of which will develop into a baby identical to the other.
17
Q
Dizygotic twins
A
formed when the mother’s body releases multiple eggs and at least two are fertilized or when another ovulation occurs even though the mother has already become pregnant.
18
Q
3 stages of prenatal development
A
germinal (first 2 weeks of pregnancy where cells move into uterus) , embryonic (2-8 weeks when vital organs and structures of the baby form), fetal (9 weeks-birth where tremendous growth occurs, length and weight increase, and organs continue to become fully functional)
19
Q
4 critical areas of newborn adjustment

21
Q
sensory development (most developed to least function)
A
touch, smell, taste, hearing, vision (poor color perception until 6 mos)
22
Q
Synaptic pruning
A
unused synaptic connections and nerve cells are cleared away to make way for functioning connections and cells
23
Q
Piaget’s 4 stages of cognitive development
A
Sensorimotor: Children form schemes (mental concepts) as they experience new situations and events
Preoperational: Assimilation—children learn new things in terms of schemes they already possess
Concrete operations: Accommodation
Formal operations: Altering and adjusting old schemes to fit new information and experiences
24
Q
Vygotsky’s The Importance of Being There
A
Role of others in cognitive development
Emphasized on social interactions
Scaffolding –> more skilled learner gives help to a less skilled learner, reducing the amount of help as the less skilled learner becomes more capable
25
Stages of Language Development
1.Cooing (2 mos)
2.Babbling (6 mos)
3. One-word speech (before 1 yr)
4. Holophrase—whole phrase in 1 word
5. Telegraphic speech (1.5 yrs)
6.Whole sentences
26
Zone of Proximal Development (ZPD)
Difference b/ween what a child can do alone and what the child can do with the help of a teacher
27
Temperament
behavioral characteristics that are fairly well-established at birth
Easy—regular schedule, adaptable, happy, easily soothed when distressed
Difficult—irregular schedule, unhappy about change, loud, active, crabby
Slow to warm-up—less grumpy, quieter, slow to adapt to change
28
Attachment
emotional bond between an infant and primary caregiver; forms in 1st 6 mos
Secure—willing to let go of mom, happily explored going back to mom now & then. Upset when mom left, happy when she came back
Avoidant—willing to explore, did not touch base, reacts very little to mom
Ambivalent—mixed feelings; clinging & unwilling; welcomed mom but pushed her away
Disorganized-disoriented—not decided how to react; approach mom but eyes turned away
Mom's behavior affect infant's attachment

Distinguish the major research methods used in the field of human development and
provide examples of each. What are the advantages and disadvantages of each?
longitudinal: one group of people is followed and assessed at different times as the group age
-->advantage: looking at real age-related changes as those changes occur in the same individuals
--> disadvantages: lengthy amount of time, money, and effort involved in following participants over the years, as well as the loss of participants when they move away, lose interest, or die.
cross-sectional: several different age groups are studied at one time
--.advantages: quick, relatively inexpensive, and easier to accomplish than the longitudinal design.
-->disadvantage is that the study no longer compares an individual to that same individual as he or she ages; instead, individuals of different ages are being compared to one another. Differences between age groups are often a problem in developmental research
cross-sequential: combo of longitudinal & cross-sectional; several diff age groups assessed at diff times
78
What is the critical period? What are teratogens? List four common teratogens and

Teratogens are agents that cause an abnormality following fetal exposure during pregnancy.
Teratogens:
* Cocaine: Decreased height, low birth weight, respiratory problems, seizures, learning
difficulties; infant is difficult to soothe
* Alcohol: Fetal alcohol syndrome (intellectual disability, delayed growth, facial
malformation), learning difficulties, smaller than normal head
* Nicotine: Miscarriage, low birth weight, stillbirth, short stature, intellectual disability,
learning disabilities
* Caffeine: Miscarriage, low birth weight
Radiation Higher incidence of cancers, physical deformities
79
Summarize Jean Piaget's stages of cognitive development and the major milestones
accomplished and limitations at each stage.
1. Sensorimotor (birth-2)==> children explore the world using senses & movement; object permanence & understanding that concepts and mental images= people, objects, events
2. Preoperational (2-7)==> children can mentally represent and refer to objects & events with words, pictures, or pretend; can't conserve, reason, or consider many object characteristics at once
3. Concrete operations (7-12)==> able to conserve, reverse thinking, and classify objects; can think logically & understand analogies (only take things literally)
4. Formal operations (12-adulthood)==> abstract reasoning about hypotheticals, logical possibilities, abstract analogies, systematically examine & test hypotheses
80

--> limitations: develop mistrust and don't expect needs to be met
2. toddler (1-3)--understand how to control own actions (autonomy vs. shame/self-doubt)
--> success: controlling own actions= develop independence
-->limitations: independence attempts blocked= sense of self-doubt & shame
3. preschool (3-5)--learn to take responsibility for own behavior, develop self control (initiative vs. guilt/irresponsibility/anxiety)
-->success: feel capable and develop sense of initiative
--> limitations: feel irresponsible, anxious, and develop a sense of guilt
4. elementary (5-12)--learn new skills in academic & social worlds and compare themselves to others to measure success or failure (industry vs. inferiority)
--> success: feel competent and improve sef-esteem
-->limitations: feel like they failed in learning skills, feel inferior to others
5. adolescence (13-early 20s)--must decide who they are, what they believe, and what they want (identity vs. role confusion)
--> success: stable sense of identity
--> limitations: confusion & isolation from others or try to be like everyone else (instead of adopting own identity)
6. early adulthood (20s-30s)--finding a person to share their identity with in an ongoing, close, personal relationship (intimacy vs. isolation)
--> success: fulfilling relationship (s) founded on psychological intimacy
--> limitations: isolation and experience loneliness, even in shallow relationships with others
7. middle adulthood (40s-50s)--find a way to be creative and productive to nurture next gen (generativity vs. stagnation)
--> success: have legacy for future
--> limitations: remain stagnated, self-centered, feel like they haven't made a difference
8. late adulthood (60s-beyond)--coming to terms w/ end of life & acceptance of life
--> success: "let go" of regrets, sense of completion, death as last stage of full life
--> limitations: cannot let go of regrets, sense of having left things until too late; see death as too soon
81
Summarize Kübler-Ross's five stages of death and dying. How are they experienced?
