Child Psych - Test #1 Flashcards
Biological: Maturational Theory (Gesell)
Everything is a result of child’s biological makeup
Biological: Ethological Theory (Lorenz)
Behaviours are inherited to achieve survival - imprinting and attachment
- Duck experiment
Psychodynamic: Psychosexual Theory (Freud)
- Oral
- Anal
- Phallic
- Latent
- Genital
Psychodynamic: Personality Theory (Freud)
Ego balances Id (devil) and Superego (angel)
Psychodynamic:
Psychosocial (Erikson)
- Trust vs mistrust - feeling safe
- Autonomy vs doubt - independence
- Initiative vs guilt - trying new things
- Industry vs inferiority - learn basic skills
- Identity vs identity crisis - develop sense of self
Learning: Classical Conditioning (Pavlov & Watson)
Associates unconditioned stimulus that results in response with a conditioned stimulus.
- Pavlov’s dog - associative learning
- Little Albert - condition to feel something to previously neutral thing
Learning: Operant Conditioning (B.F. Skinner)
Learn through reward and punishment for behaviour.
- Skinner box
Learning:
Social Cognitive Theory (Bandura)
Behaviour is learned through observational learning.
- Bobo the doll
Cognitive Development (Piaget)
Cognitive development occurs due to biological maturation - Logic!
- Piaget’s experiment with liquid in containers & coins lined up
Contextual: Sociocultural Theory (Vygotsky & Brofenbrenner)
Stresses the interaction between developing people.
- Vygotsky - Adults teach culture.
- Brofenbenner - Everything in a child and they environment affects how they develop (siblings, friends, etc.)
Data Collection:
Reports vs Observation vs Tasks
Reports- questionnaire or interview
Observe - spy or in setting/lab
Task - colour perception, memory, recognize emotions…
Research Designs:
Correlation vs Experiment
Correlation - relationship between two things
Experiment - you control a variable, not solely observe
Methods for Studying Development:
Longitudinal vs Cross-Sectional vs Sequential
Longitudinal - same age & tested +1
Cross-Sectional - different ages & tested 1
Sequential - different ages & tested +1
Genotype vs Phenotype
Genotype: Set of genes we carry
Phenotype: All our observable characteristics
Gene
A pair of alleles
Homozygoys vs Heterozygous
Homo: Identical alleles
Hetero: Different alleles
Dominant Allele vs Recessive Allele
Dominant: Leader
Recessive: Follower
Sickle Cell Trait
Condition where a person has one abnormal allele of the hemoglobin beta gene.
* Sickle cell disease = 2 copies of this allele
Single Gene vs Polygenic Inheritance
Single: Controlled by one gene.
Polygenic: Controlled by 2+ genes - each gene often has two or more alleles.
How to study behavioural genetics?
Twins or Adoption
Strong cases for inheritance
- Intelligence
- Psychological disorders
- Personality
Inherited Disorders
Usually consist of 2 recessive alleles.
- Albinism, PKU, Tay-Sachs, Cystic Fibrosis, Huntington’s
Abnormal Chromosomes - Disorders
Either too many, too few, or damaged chromosomes.
- Down Syndrome (extra 1)
Either missing or extra sex chromosomes.
- Height, sex, characteristic, and cognitions…
Reaction Range
When the phenotype of an organism depends both on the organism’s genetic characteristics (genotype) and environment.
Stage #1 of Prenatal Development
Zygote:
- Egg fertilized in fallopian
- Rapid cell division
- Zygote implanted in uterus wall
Stage #2 of Prenatal Development
Embryo:
- Body parts are formed
- Embryo in amniotic sac
- Umbilical cord joins embryo to placenta
- 6wks = apple seed, 7wks = grape, 8wks = strawberry
Stage #3 of Prenatal Development
Fetus:
- Increase in size and systems function
- Age of viability = 22-28 wks
Risk Factors of Pregnancy
- Nutrition
- Stress
- Mother’s Age
- Teratogens:
- Infections and diseases
- Drugs/Medications
- Environmental hazards
Prenatal Disgnosis & Treatment
- Deformities and genetic disorders = ultrasound, chorionic villus sampling, amniocentesis
- Fetal medicine and surgery
Labour & Delivery Stages
#1: Uterus contracts, cervix enlarges #2: Baby is pushed down birth canal, baby is born #3: Placenta is expelled
Birth Complications
- Lack of O2 or baby’s position = C- Section
- Placental abruption
- Premature (< 38wks)
- Small-for-date (low lbs)
4 Primary States
- Alert inactivity
- Waking activity
- Crying
- Sleeping
