1. Infancy & Childhood
Unit 4
Lesson 2
Day 1

2. 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

3. Warm Up Identify one thing you learned about prenatal/neonatal…
Physical dvpt
Sensory dvpt
Social dvpt

4. Homework Review Which decade was the easiest?
Which decade was the most difficult?
What words are most commonly associated with particular decades? Why?

5. Infancy Motor Development Maturation:
Increasing coordination of muscles for physical mvmt
Maturation:
Genetically programmed growth & dvpt
Researchers believe that that we are hard-wired to sit up, pull up, walk at particular ages…maturation – genetically programmed growth & dvpt…
Motor dvpt influenced by maturation, mixed with active exploration of environment!

6. 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

7. 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)

Avery’s Motor Milestones P.Pt

9. Language
Learned, systematic code that enables us to communicate meaningful ideas.
5 Forms: Reading, Writing, Gesturing, Signing, Speaking

10. Language Expressive Language: Receptive Language:
Learning to speak and use language
Receptive Language:
Learning to listen and understand language

11. 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.

12. Language Milestones 0-1 m CRY 2 m COO 5-7 m BABBLE 12 m WORD
18 m OVEREXTENSION
2 y TELEGRAPHIC
3 y TENSE
4-6 y SENTENCES, QUESTIONING
7-9 y MULTIPLE MEANING
Continues to expand thru life
Language acquisition continues throughout life- expand vocab, articulation

13. 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
Humans have critical periods in areas of socialization, motor skills, language!

14. Social Dvpt Attachment Harry Harlow
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

15. Social Dvpt Attachment Styles Separation Anxiety – (6/8m – 14/18m)
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
Secure - Unhappy when mom left, but played w/stranger. Happy upon return.
Anxious-Ambivalent – upset when mom left, but resist contact upon return
Avoidant – not upset when mom left, avoided mom upon return

16. Closure
Explain attachment and identify one psychologist & their contribution to this area of study.

17. Infancy & Childhood
Unit 4
Lesson 2
Day 2

18. Objectives:
Identify the importance of attachment for social development.
Evaluate examples of isolation in humans; including the infamous Genie case.

19. Warm Up.
What is attachment and why is it important to (an infant’s) social development?

20. Isolation in Humans Feral Children Institutionalized Children
Raised in wild
Victor
Institutionalized Children
Foster vs Institutions
Cases of Abuse
Raised in near total isolation
Genie

21. 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?

22. Genie: Secrets of the Wild Child

23. 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?

24. Closure
What are critical periods?
