Fetal Auditory Learning by dffhrtcv3


									Fetal Auditory
 Why parents should invest in
teaching their unborn children:
   Mother – Child Bonding
   Language Acquisition
   Higher Intelligence
        Mother – Child Bonding:
   Neonates and full-term babies both show voice
   Major contributors: DeCasper, Spence, Fifer
    find that infants
     Do not show a discrimination of male voices
     Prefer female voices to male voices

     Prefer mother’s voice to other females’ voices

     Prefer mother’s language to unknown languages
           Experimental evidence:
   Procedure:
     3 – day old neonates were presented with either their
      mothers voice or another woman’s voice, depending
      on how often they sucked on a fake nipple
     Others presented with male / female stimuli

   Conclusion:
       “feedback to the maternal voice provided clear
        evidence of auditory discrimination; the probability
        of sucking … was greater when the sucking
        produced the maternal voice”
        Explanation of these results:
   The uterine environment around the fetus
    blocks some sounds
     Blocks most of the spectrum of male speech
     Allows in some information from female speech

     Internal vibration increases the volume of the
      maternal voice
   Reciprocal
     Mothers can feel child moving in response to sounds
     Child experiences many physiological states similar
      to their mother
   Why bond?
     Allows for quicker identification of mother after
     Reinforced by her odor and manner of handling
    Speech Perception & Language
   What is learning?
       Learning is a relatively permanent change in
        behavior that is developed over times as a result of
Speech Perception & Language:
   Influence of prenatal auditory stimulation on
    postnatal auditory preferences
   Fetal familiarity with recurrent speech sounds
   Two major studies by Anthony DeCasper:
     Preference of a passage read by mother
     Prenatal exposure to maternal speech influences
   Hypothesis:
       The child would show preference towards a passage
        recited repeatedly by mother during pregnancy
   Results:
       Language-relevant cues in the passage stimulate a
        response from the baby
   Hypothesis:
       Prenatal maternal speech has an influence on the
        development of speech perception
   Results:
     Key characteristics of language are learned prenatally
     Language acquisition skills are developed
            Higher Intelligence:
   What is Learning?
   John Watson
   Piaget's sensorimotor stages
   Baby Plus product
   Conclusion
Baby Plus
   Mother – Child Bonding
     Newborns can already identify their mother’s voice
     Allows for easier attachment to a significant adult

   Speech Perception & Language
     Prenatal exposure shapes later preference
     Key parts of language may be learned prenatally

   Higher Intelligence
     Relatively permanent effects
     Important period of development before & after
