Developmental Psychology

Research Methods: Cross-Sectional = compare different age groups at the same time Longitudinal Studies = study one group over a long period of 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)

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

Kubler-Ross's Stages of Death/Grief 1. Denial 2. Anger 3. Bargaining 4. Depression 5. Acceptance

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

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)

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+)

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

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)
