Exam 1 Flashcards
Freud’s three parts of personality
id, ego, superego
Domains of Development
Physical Cognitive Emotional and Social
6 Periods of development
Prenatal Infancy and Toddlerhood Early Childhood Middle Childhood Adolescence Emerging Adulthood
Age range of Prenatal period of development
Conception to birth
Age range of Infancy and Toddlerhood period of development
Birth to 2 years
Age range of Infancy and Early Childhood period of development
2 to 6 years
Age range of Infancy and Middle Childhood period of development
6 to 11 years
Age range of Infancy and Adolescence period of development
11 to 18 years
Age range of Infancy and Emerging Adulthood period of development
18 to 25 years
-Inborn, biological givens -Based on genetic inheritance
Nature
-Physical and social world -Influences biological and psychological development
Nurture
An orderly, integrated, evidence-based set of statements that Describes, Explains, and/or Predicts behavior
Theory
What factors offer protection from the damaging effect of stressful lives?
-High intelligence and socially endowed talents, including temperament -A warm parental relationship -Social support outside the immediate family -Community resources and opportunities
id
Largest portion of the mind Unconscious, present at birth Source of biological needs & desires
ego
Conscious, rational part of mind Emerges in early infancy Redirects id impulses acceptably
superego
The conscience Develops from ages 3 to 6, from interactions with caregivers
Erikson’s Psychosocial Stages
Basic trust vs. mistrust (Birth to 1 year) Autonomy vs. shame and doubt (1 to 3 years) Initiative vs. guilt (3 to 6 years) Industry vs. inferiority (6 to 11 years)
tabula rasa
John Locke’s “blank slate” view (17th Century)
store and transmit genetic information.
Chromosomes
segments of DNA located along the chromosomes.
Genes
substance of which genes and chromosomes are made.
DNA
The 22 pairs of chromosomes that are not sex chromosomes
Autosomes
-23rd pair of chromosomes -Determine sex -XX = female, XY = male
Sex Chromosomes
Sperm and ova
Gametes /Sex Cells
Sperm and ovum united
Zygote
Two zygotes, or fertilized ova
Fraternal/Dizygotic
One zygote that divides into two individuals
Identical/Monozygotic
Homozygous
The two alleles are the same
Heterozygous
The alleles differ
Forms of the same gene on a pair of chromosomes
Allele
If homozygous genotypes are represented by BB (normal) and bb (affected) and heterozygous genotypes are represented by ___ (carrier genotype)
Bb
DOMINANT trait examples
Dark Hair Curly Hair Facial Dimples Normal Vision Normal Hair Type A Blood
RECESSIVE trait examples
Blonde Hair Straight Hair No Dimples Nearsightedness Pattern Baldness Type O Blood
X-Linked Inheritance1q1
The X chromosome has one abnormal recessive allele
Imprinting
Mother’s or father’s allele is chemically marked and thus activated Often temporary
Mutation
Sudden, permanent change in a DNA segment
results from problems with the 21st chromosome
Down Syndrome
problems with the X or Y chromosomes
Sex Chromosome Abnormalities
Periods of Prenatal Development
Zygote, Embryo, Fetus
Zygote length and key events
2 weeks. Fertilization Implantation Start of placenta
Embryo length and key events
6 weeks Arms, legs, face, organs, muscles all develop Heart begins beating
Fetus length and key events
30 weeks Growth and finishing
Any environmental agent causing damage during prenatal period
Teratogen
Sensitive Periods in Prenatal development
Week 3 (heart) through week 16 (brain)
FAS is diagnosed only when a child has the following major clinical manifestations, or signs
-Growth retardation -Characteristic facial features, such as: Small eyes with drooping upper lids , short, upturned nose, flattened cheeks, small jaw, thin upper lip, flattened philtrum (the groove in the middle of the upper lip) -Central nervous system problems -Decreased birth weight -Small skull -Hearing disorders
The Apgar Scale
Appearance Pulse Grimace Activity Respiration
How is Apgar scored and when does it occur?
Score of 0-10 at 1 minute and 5 minutes after birth
-Born weeks before their due date -May be appropriate weight for length of pregnancy
Preterm
-May be born at due date or preterm -Below expected weight for length of pregnancy
Small-for-Date
-Portion of individual differences attributable to genetics -Obtained from kinship studies -Ranges from 0 to 1.00
Heritability Estimates
-What percent of the time do twins both show a trait? -Ranges from 0 to 100%
Concordance
inborn automatic responses to particular forms of stimulation
Reflexes
closes eyes quickly and protects infant from strong stimulation
eye blink
helps the baby find the mother’s nipple – has survival value
rooting
permits feeding
sucking
helps infant survive if dropped in water
swimming
or embracing reflex helps babies survive during our evolutionary past
moro
prepares infant for voluntary grasping
palmar grasp
