  • Background:
    • Children from families with high SES have a bigger vocabulary
  • Research Question:
    • Is there an association of SES with gesture usage frequency during child-parent interactions?
    • Can these association explain the vocabulary disparities when entering school?
  • Method:
    • 14 month-old children
      • 90 minute videotaping while at home
      • measured:
        • number of different gesture meanings
        • number of different word roots
        • SES
    • same children at 54 months old: vocabulary
  • Results:
    • SES correlated positively with number of gestures
    • number of gestures of parents correlated with child gestures
    • number of gestures correlates with vocabulary of children (at 54 months)
  • Interpretation:
    • high SES -> more gestures
    • vocabulary differences (at 54 months) can be explained through gestures differences (at 18 months)
    • gestures is mediating variable
