  3. 3. JEAN-MARC-GASPARD ITARD TRIES TEACHING SPEECH BUT TRIES READING AND FAILS WRITING WITH SUCCESS - Set up an ambitious program - Named him as Victor - Focuses on sharpening perceptual abilities - Started the lesson with variety - Started to expose to letters of games and activities that was of the alphabets responded dramatically - Victor’s progress and difficulties faced - Imposed drilling method - Exposed to speech organs and sounds - Victor’s responses - Concludes that communication is language and not mere recognition of environment context ANOTHER ATTEMPT ON TEACHING SPEECH - End of fifth year - Failed and gives up - Arranged a place for Victor to live in a house with Madam Guerin - Victor lived for 18 years as a mute - Died at the age of 38
  4. 4. Discovered in the early 1970’s at the LA, California Was locked away by her father for 12 years who had beaten her frequently Discovered at the age of 13 in a pitiful state and no knowledge of language when her mother escaped with her GENIE : RAISED IN ISOLATION (A PSEUDONYM) Just started to acquire language around 20 months of age Brutally tormented by her father who eventually committed suicide on the day of trial for mistreating his child
  5. 5. GIVEN FREEDOM AND CARE - During first few weeks, she was alert and curious - Had little understanding of grammatical structures - Responded only to gestures and intonation of words - Later, changed considerably - Acquired words for a hundreds of objects out of curiosity RESPONDS LINGUISTICALLY AND SOCIALLY - After a year, evaluated again on her language ability - Tested on a variety of syntactic structures - Tested on her understanding of adjectives and prepositions - Improved quite rapidly in understanding speech but slow in speech production A PEAK IN LANGUAGE LEARNING - Progressed a little after eight years of being studied - Language ability remained below normal and continued to be ungrammatical - Placed in a home for retarded adults
  6. 6. Mason’s opinion on Isabelle while attending her at the Children’s Hospital, Columbus, Ohio (11/ 1938) Started gaining language at six and a half years after freedom through her mother Sustained a brain injury at two years old
  7. 7. HER PROGRESSION? LESS THAN THREE MONTHS FIRST ONE WEEK Produce sentence utterances First attempt of vocalization ONE YEAR Listens attentively to and retells a story in own words A YEAR AND HALF Complex structures 20 MONTHS LATER Produce full sentence
  8. 8. CHELSEA : BEGAN TO LEARN LANGUAGE AT THE AGE 32 Mistaken for being deaf at birth (a pseudonym) Not given any form of language training/ instruction WHY? At 32, discovered is only partially hearing- impaired and later, with hearing aids, she was able to hear speech relatively normal
  9. 9. Became deaf & blind at the age of 19 months due to illness Became an acclaimed lecturer and writer in the service of handicapped people Had some exposure on learning language before illness At the age of 7, introduced to ANNE SULLIVAN MACY Who was she? HELEN KELLER : THE RENOWNED DEAF AND BLIND GIRL Macy’s efforts to teach language via touching sense succeeded Learned to read & produce Braille and graduated from Radcliff Able to produce somewhat strange speech Why? Helen learned via touching speech articulators and even learned to speak
  10. 10. Discovered in 1991 living in a kennel after abandoned by alcoholics parents during the age of 3 OXANA: RAISED BY DOGS Given shelter by a dog family for the next 5 years who eventually behaved like a ‘dog’ when discovered Last reported 2 years back, she was living in a home for the mentally ill where her speech has improved though had difficulties in relating to people Her doctor, Vladimir Nagorny, stated that her development seem to come to a limit and though they have been trying to find her a job, she will never be considered as a normal person
  11. 11. Discovered in 1999 when 4 years old by social workers in a deserted apartment Survived by stray dogs since 2 years old after abandoned by an alcoholic mother Language skills and grammar slowly improved where at the age of 6, speech production was equivalent to a 3 years old Was living in a foster home after two years of his discovery James Law studied Edik and remains optimistic abut his language progress
  12. 12. EXPOSURE TO LANGUAGE WHY DID ONLY ISABELLE AND HELEN FULLY LEARN LANGUAGE?
  13. 13. EXTENT OF ANY PHYSICAL, PSYCHOLOGICAL & SOCIAL TRAUMA PRIOR EXPOSURE AGE OF EXPOSURE FACTORS GOVERNING LANGUAGE LEARNING
  14. 14. WHY DID GENIE NOT PROGRESS MORE THAN SHE DID? Curtiss concludes that Genie had a clear semantic ability but could not learn syntax WHY? Factors contributing to her faulty in speech production in terms of pronunciation
  15. 15. Crucial data for critical age lie in syntactic understanding and not production CHELSEA : INSUFFICIENT EVIDENCE Chelsea’s abilities in this scope was not sufficiently assessed Curtiss debated that Chelsea’s case proves that beyond a critical period, other aspects of language can be learned but not syntax (not substantiated)
  16. 16. THE ACHIEVEMENTS ISABELLE Performed well despite received no language exposure until the age of six and a half Gained a benefit from mother’s affection and social support Gestures shared between her mom may have helped to understand the relationship between object & symbol crucial for language learning HELEN Was exposed to language during the first 19 months old Had a loving family Was supported by family throughout her language deprivation period
  17. 17. Isabelle & Helen started to learn language at an early age following a relatively short period of deprivation Clearly, the idea experimental situation to study this has not yet presented itself Victor, Genie, Chelsea did not learn much language IS THERE A CRITICAL AGE FOR FIRST LANGUAGE LEARNING ? Lenneberg suggested this may be due to biological maturation of brain Certainly, critical age could not be below six or seven
