      What second languages are most popular among the Japanese? Does learning certain languages pose more benefits than learning others?
  • apply the principles of first language acquisition to their second language learning experience
  • bilingual upbringing
  • ...34 more annotations...
  • area of the brain
  • second language development in Japan.

      What about learning second languages in other countries?
  • Broca’s area
  • native like quality exposure
  • six year period
  • how much exposure to a second language should a kindergarten-aged child receive in order to develop native like competency or at least reduce such barriers?

      Does that mean that we were capable of learning a second language like a native language in kindergarten?
  • English as a second language in Japan
  • motivation to continue studying English throughout the secondary school years will be much higher

      Maybe this is true for music, sports, etc. too
  • decline in learning abilities from puberty
  • critical period for second language learners
  • it is possible for adult learners to achieve native like performance
  • alternative to the critical-period hypothesis is that second-language learning becomes compromised with age
  • children growing up without normal linguistic and social interaction

      Reminds me of the Forbidden experiment
  • 20 months until age 13
  • inconceivable mental and physical disabilities
  • syntactic skills were extremely deficient
  • Genie used her right hemisphere for both language and non-language functions
  • particularly good at tasks involving the right hemisphere
  • 46 Chinese and Korean natives living in America
  • three and seven years of age on arrival did equally as well as the control group of native English speakers. Those between eight and fifteen did less well

      It would be interesting to replicate this experiment here where we have mixed ethnicities.
  • regardless of what language is used elevated activity occurs within the same part of Broca’s area
  • early bilingual subject
  • For monolingual parents living within their own monolingual society it is possible to raise a child bilingually
  • 95% of people the left hemisphere of our brain is the dominant location of language
  • two specific areas that divide language by semantics (word meaning)
  • People with damage to Broca’s area are impaired in the use of grammar with a notable lack of verbs however are still able to understand language
  • actual development of our language centers begins well before birth
  • supports the notion of speaking to your child before birth
  • Japanese babies can detect the difference between the /l/ and /r/ sounds which proves most difficult for their parents
    • Kathryn Murata

      Can Japanese people still pronounce sounds like "L" at any age?
  • survival of the fittest
  • critical period of development is when there is an excess of synapses and the brain plasticity remains at a maximum

      Connections between science and language, Darwin's theory of evolution (survival of the fittest)
  • importance of experience during sensitive period of language development
  • age related factors may impair our ability in acquiring a second language
  • child’s parent’s own 2nd language ability

    The chair squeaked quietly as I fidgeted, swiveling left, right, left. I sat toward the back of a long wooden table flanked by my fellow graduate students, while a pair of eminent biologists led a discussion on how to talk to skeptical non-scientists about evolution.
