NATURE
-Genetics
-Heritability
-we are born the way we are
NURTURE
-Environment
-Experience
-we are raised a certain way
Research Methods:
Cross-Sectional = compare different age groups at the same time
Longitudinal Studies = study one group over a long period of time
PHYSICAL DEVELOPMENT
physical changes over time
Prenatal Development
1. ZYGOTE - fertilized egg + 2 weeks + rapid cell division
(zygote attaches to uterine wall)
2. EMBRYO - 6 weeks + critical development (heart beat/ organs develop)
3. FETUS - 9 weeks till birth + grow + sensory system developed (can hear/respond to light)
(by 6 months, stomach/organs have developed enough to survive outside of mother)
Critical Periods
(once embryo begins to receive nourishment from placenta it becomes vulnerable to hazards/diseases/toxins that can affect periods of growth)
ARMS and LEGS - 3.5 to 8 weeks
HEART - 2.5 to 6.5 weeks
CNS - 2 to 5 weeks
EYES - 3.5 to 8.5 weeks
TEETH/ROOF OF MOUTH - 7 to 12 weeks
Teratogens = chemical agents that can harm the prenatal environment
Alcohol - Fetal Alcohol Syndrome (FAS) causes physical and cognitive abnormalities and is the leading cause of intellectual disabilities
STD's - HIV, Herpes, Genital Warts
Sensory Development
most sensory abilities are well developed at birth
-touch is the best, then smell and taste
-hearing develops once fluid from womb clears out
-vision is least functional at birth (newborns have preference for complex patterns/three dimensions/human faces)
Healthy Newborns
turn head towards voices + can see 8-12 inches from their face + gaze longer at human-like objects
Reflexes : inborn automatic responses
- rooting, sucking, grasping, moro (safety: fling limbs out and then curl up into a little ball), Babinski (stoke foot and toes spread), gagging
Motor Development
GROSS: big body parts FINE: little body parts
1. Raising Hand and Chest (2-4 months)
2. Rolling Over (2-5 months)
3. Sitting Up With Support (4-6 months)
4. Sitting Up Without Support (6-7 months)
5. Crawling (7-8 months)
6. Walking (8-18 months)
Maturation = physical growth regardless of environment
Puberty
= period of sexual maturation, during which a person becomes capable of reproducing
Primary Sexual Characteristics = body structures that make reproduction possible
Secondary Sexual Characteristics = non-reproductive sexual characteristics
Adulthood
all physical abilities essentially peak by our mid 20's, the it all goes downhill
Life Expectancy: keeps increasing (82 right now), women outlive men by 4 years
SOCIAL DEVELOPMENT
being able to interact with others
Attachment
( imprinting)
= close emotional bond between infant & birth giver.
Harlows Monkeys
= showed that touch was needed to form attachment
Types of Attachment
1. Secure
(plays w toys, cry when mom leaves, happy when she returns)
2. Avoidant
( plays w toys, don't go to parents fro comfort when they return)
3. Anxious/ Ambivalent
(shw stress when parents leave, dont want comfort when they return)
Strange Situation
(Mary Ainsworth)
=See how kids behave in a playroom, then when mom leaves and when she returns
Temparement
= behavioral characteristics that show a particular mood at a particular time
EASY- happy child, easy to please
DIFFICULT -irregular sleep patterns, hard to please
SLOW TO WARM UP- less grumpy then difficult child, slow to adapt to change
Parenting Styles
Authoritarian- have important rules ( Bc I said so)
Permissive- submit to child's desires,few demands/ punishment
- (Neglectful/Indulgent)
Authoritative- demanding but responsive/ reasonable? encourage discussion
Stage Theories
= travel from stage to stage in our lifetimes
FREUD
= psychosexual stages of developement
= sex drives everything
= libido yravels to different parts of the body through out life
PSYCHOSEXUAL STAGES OF DEVELOPEMENT
1. Oral Stage: all pleasure comes in through mouth (0-2)
2. Anal Stage: controlling/ expelling waste (2-4)
3. Phallic Stage:recognizes gender/ shows jealousy (4-7)
5. Latency Stage:cooties (7-11)
6. Genital Stage: focused on genitals for the rest of time (12- death)
ERIKSON
= neo-freudian
= personality is influenced
=psychosocial development
PSYCHOSOCIAL STAGES OF DEVELOPPMENT
1. Trust vs Mistrust (0-2)
2. Autonomy vs Shame/Doubt (1-3)
3. Initiative vs Doubt (3-5)
4. Industry vs Inferiority ( 5-12)
5. Adolesence vs Role Confusion (13-20)
6. Intimacy vs Isolation (20-30)
7. Generativity vs Stagnation (40-50)
8. EgoIntegruty vs Despair (60+)
COGNITIVE DEVELOPMENT
Piaget: kids learn differently than adults
Schemas
= mental containers that help us interpert our world around us
Assimilation
= incorporate new experiences into exsiting schemas
Accomodation
= adapt our understandings (schemas) to incorporate new info
PIAGETS STAGES OF DEVELOPMENT
Sensorimotor (0-2)
= experience the world through our senses
= no object permanance
Preoperational (2-7)
= have object permanance
=begin to use language
=egocentric
=no conservation/ logic
=animism
=irrevirsibility
Concrete Operational (7-12)
= logical thought processes
=understand conservation/ irrevirsability
Formal Operational (12- adulthood)
= abstract reasoning/ hypotheis testing
= Trial & Error
= Metacongnition
( not everyone gets to this stage)
TYPES OF INTELLIGENCE
Crystalized- accumulated knowledge
Fluid- solve problems quickly and abstractly
MORAL DEVELOPMENT
Heinz Dilemma
(places you in a stage)
= Partner is sick and dying and needs a drug they can't afford. Do they steal it or not?
Pre-Conventional
= morality based on rewards and punishments
STAGE 1 - obedience & punishment (avoid punishment)
STAGE 2 - self interest (rewards/benefits that interest you the most)
Conventional
= morality based on how others see you
STAGE 3 - conformity (secure approval/be a good kid/do what others are doing)
STAGE 4 - authority & social order (law and order/do your duty)
Post-Conventional
= morality based on self-defines ethical principles
STAGE 5 - social contract (what's morally right may not be what's legally right)
STAGE 6 - Universal Ethical Principles (human life has an inherent value and is more important that all laws/rules)
