Objectives Review early development Identify stages of infant motor & language dvpt. Examine relationship between attachment and development Analyze critical periods by looking at a case study
Warm Up Identify one thing you learned about prenatal/neonatal… Physical dvpt Sensory dvpt Social dvpt
Homework Review Which decade was the easiest? Which decade was the most difficult? What words are most commonly associated with particular decades? Why?
Infancy Motor Development Increasing coordination of muscles for physical mvmt Maturation: Genetically programmed growth & dvpt
Activity: Place abilities in order from 1-8 Walks alone; says several words Turns head to follow moving object Climbs stairs; says many words Laces shoes Sits alone for 1 min; says “da-da” Puts on shoes Runs; uses simple word combinations Walks while holding onto something
Activity Answers Turns head to follow moving object (2m) Sits alone for 1 min; says “da- da” (9m) Walks while holding onto something (1y) Walks alone; says several words (1y 3m) Climbs stairs; says many words (1y 6m) Runs; uses simple word combinations (2y) Puts on shoes (3y) Laces shoes (4y)
Motor Milestones Dvpt Norms (median age)… Lift head: 2 m Roll over: 3 m Prop Up: 4 m Sit Alone: 5.5 m Stand w/Help: 7 m Crawl/Creep: 7-12 m Stand Alone: 12 m Walk: 12-15 m Walk backward: 14 m Steps: 17 m Avery’s Motor Milestones P.Pt
Language Learned, systematic code that enables us to communicate meaningful ideas. 5 Forms: Reading, Writing, Gesturing, Signing, Speaking
Language Receptive Language: Learning to listen and understand language Expressive Language: Learning to speak and use language
Language Theories Nativist Theory Language Acquisition Device: Noam Chomsky said we are predisposed to acquire language Learning Theory B.F. Skinner: Kids learn language through observation and imitation of parents Mix: Eric Lenneberg said language is inborn, but must be learned during critical period (18m– Puberty) and is influenced by environment.

Critical Periods Period during which certain skills or behaviors must be acquired. If not, learned with great difficulty or not learned at all. Konrad Lorenz Baby Geese & Imprinting http://www.youtube.com/watch?v=2UIU9XH-mUI&p=28B409BFB6FF150C&index=17&feature=BF
Social Dvpt Attachment Close bond b/t infants & caregivers Harry Harlow Monkey’s & Surrogate Moms Contact comfort – physical closeness w/caregiver Preferred security to food Abnormal behaviors if raised in isolation http://www.youtube.com/watch?v=tlJS8LeLWjs&feature=related
Social Dvpt Attachment Styles Mary Ainsworth’s Strange Situation Secure – infant seeks proximity, contact, & interaction w/caregiver Insecure – infant cannot be calmed or ignores the caregiver after the separation Anxious-Ambivalent Avoidant Separation Anxiety – (6/8m – 14/18m) Emotional distress when separated from people they’re attached to http://www.youtube.com/watch?v=SHP_NikTkao
Closure Explain attachment and identify one psychologist & their contribution to this area of study.
Objectives: Identify the importance of attachment for social development. Evaluate examples of isolation in humans; including the infamous Genie case.
Warm Up. What is attachment and why is it important to (an infant’s) social development?
Isolation in Humans Feral Children Raised in wild Victor Institutionalized Children Foster vs Institutions Cases of Abuse Raised in near total isolation Genie
Genie- Wild Child Reading 1970 LA social workers found neglected and abused 13 yr old suffering from physical, cognitive, social impairments. Having missed critical periods, could she learn to walk, talk?

Genie Discussion What are some examples of the impact of her isolation on her development? Why is this called the forbidden experiment? Was Genie exploited in the name of science or were the researchers genuinely concerned for her welfare?
