  1. Pointing Entering the World of Communication Open Janea’s website with Internet Explorer www.stfx.ca/people/jlayes

  2. Declarative Pointing • Sharing attention to simply share experience with others • Contrasts with Imperative Pointing, which is done to obtain objects from others • Expression of shared intentionality, a critical foundation for communication • Unique to humans? • So far, apes do not seem to understand meaning behind human points. Cannot follow gesture to food.

  3. Gestures as First Language • Bates et al., 1979 • First noted the referential function of declarative pointing • Reported early onset to pointing • happens prior to first words

  4. Gestures as First Language • Carpenter et al., 1998 • Found that pointing develops in concert with other foundations for language, between 9-12 months • Such as Joint Attention

  5. Gesturesas First Language • Liszkowski, 2005 • Reported that pointing is driven by motive to share interest AND affect • Child is not satisfied if adult doesn’t look to where they point, but also if they don’t express relevant attitude to the event

  6. Pointing: A Truly Communicative Function • Liebal et al., 2007 • Babies use shared experience to discern the meaning of the adult pointing gesture • Demonstrates keeping track of who you shared what with in interactions • Meaning of point disambiguated by the common ground you have with the other

  7. Pointing Universal Across Culture ---Callaghan et al., 2010 Objects set up for pointing experiment in Peru You will see the same set up in the Canadian video you score

  8. Part I: Data Collection Watch the video and try to tally the number of index-finger points made by both the parent and the child For the baby, you can count open-hand gestures that are not grasping, or “give me” gestures, as points You can keep a tally on loose-leaf, and then later on your Exercise Sheet just type in the final number of Points you noted. Lab Exercise

  9. Part II: Data Analysis Open the Excel file on Janea’s website Test the correlation between frequency of parent points and frequency of child points. Instructions are on Exercise Sheet. Remember: Positive Correlation: As one goes up, the other goes up Negative Correlation: As one goes up, the other goes down The closer to either +1 or -1, the stronger the relationship The closer to 0, the weaker the relationship 0 = no predictive relationship found ( See Next Slide for more help with interpreting Correlations) Lab Exercise
