Chapter 8: Development Across the Life Span Flashcards
Scientific study; changes that occur from conception to death
Human Development
One participant/group studied over long period of time
Longitudinal Design
Multiple different participant/age groups studied at one point in time
Cross-sectional Design
First studied by cross-sectional design; followed longitudinally
Cross-sequential Design
Impact on development; group shares common time period/life experience
Cohort Effect
Influence of inherited characteristics on personality
Nature
Influence of environment on personality
Nurture
Science of inherited traits
Genetics
Contains genetic material of organism
DNA
Section of DNA
Gene
Tightly wound strand of DNA
Chromosome(s)
Gene actively controls expression of trait
Dominant
Gene only influences when paired with an identical gene
Recessive
Diseases carried by ________ genes are inherited when a child inherits ____ _______ genes, ____ from each parent.
recessive; two recessive; one
(cystic fibrosis, sickle-cell anemia, Tay-Sachs, phenylketonuria)
Extra chromosome in what would be the 21st pair
Down Syndrome
Extra sex chromosome in the 23rd pair
Klinefelter Syndrome
23rd pair is missing an X
Turner Syndrome
(short, infertile, & sexually underdeveloped)
Union of ovum (female egg) and sperm (male cell)
Fertilization
Total of 46 chromosomes; result of fertilization
Zygote
Identical twins; one zygote splits into two different cell masses (one fetus)
Egg fertilized by one sperm, then egg splits in half
Monozygotic Twins
Fraternal twins; two zygotes in uterus at the same time (two fetuses)
Two eggs fertilized by two different sperms
Dizygotic Twins
Study of ethical and moral issues; biology and medicine
Bioethics
2 weeks after fertilization; zygote moves to uterus and implants in lining
Germinal Period
2 to 8 weeks after fertilization; organism being formed
Embryo
2 to 8 weeks after fertilization; major organs and structures begin developing
Embryonic Period
Environmental influences impact development of infant
Critical Periods
Any factor that can cause a birth defect
Teratogen
Consumption of alcohol through pregnancy; combination of physical, mental, & behavioral problems
Fetal Alcohol Spectrum Disorder (FASD)
8 weeks after conception until birth of baby
Fetal Period
8 weeks after fertilization until birth of baby; developing organism
Fetus
Born between 38-40 weeks? Born before 38 weeks?
Full term; Premature (preterm)
Longer infant spent looking; more attracted to that stimulus
Preferential Looking
Infants stop paying attention to stimulus that doesn’t change
Habituation
Development of thinking, problem solving, and memory
Cognitive Development
Mental concepts
Schemas
First stage; infant uses senses and motor abilities to interact with objects
Sensorimotor Stage
Knowledge object exists; not in sight
Object Permanence
Second stage; preschool child uses language to explore world
Preoperational Stage
Inability to see the world through someone else’s eyes
Egocentrism
Young child focuses on one feature; ignores relevant parts
Centration
Changing appearance does not change true nature of object
Conservation
Young child unable to mentally reverse action
Irreversibility
Third stage; school child capable of logic thought processes (beginner)
*capable of conservation and reverse thinking
Concrete Operations Stage
Fourth stage; adolescent capable of abstract thinking
Formal Operations Stage
More skilled helps less skilled learner
Scaffolding
Vygotsky; child can do alone vs help of a teacher
Zone of Proximal Development (ZPD)
Neural disorder that encompasses a whole range of previous disorders
Autism Spectrum Disorder (ASD)
Behavioral characteristics; easy, difficult, and slow to warm up; each person born with
Temperament
Emotional bond with infant and caregiver
Attachment
“Touching base”; infants explored as long as mother nearby, cried when gone
Secure Attachment
No interest or concern about mother not being around
Avoidant Attachment
“Mixed feelings”; clingy and unwilling to explore, wanted mother but would fight when she came back
Ambivalent Attachment
Unsure how to react; avoid eye contact, dazed and depressed look
Disorganized-disoriented
Image of oneself develops through interactions with important people in their life
Self-concept
Theory that development occurs in eight stages; first four in infancy and childhood
Erikson’s Theory
Contact comfort
Harry Harlow
Stage that results in sense of independence because of ability to control his or her own options
Autonomy vs Shame & Doubt
13 to early 20’s; no longer a child but not-yet self sustaining adult
Adolescence
The peak of sexual development and bodily changes
Puberty
Adolescents believe they are unique and protected from harm
Personal Fable
Adolescent thought that other people are worried about your characteristics just as much as you are
Imaginary Audience
Understanding of right and wrong
Moral Developement
Infants learn trust dependency on how their needs are met
Trust vs Mistrust
