  1. 1. Measurement, analysis, and sharing Daniel Messinger, Ph.D. University of Miami September 15, 2011 From openshapa to open data sharing
  2. 2. Overview Problem: Lack of sharing Continuous measurement  Objective—automated  Subjective  Analysis tools Categorical measurement  Analysis tools Solution? Share behavioral databases… http://measurement.psy.miami.edu/
  3. 3. Measurement problemsplague the behavioral sciences Investigator-specific systems Each lab re-invents the wheel in its own image hampering replication http://measurement.psy.miami.edu/
  4. 4. Broader systems have emerged Facial Action Coding System (FACS)Require substantial training & implementation Instantiate with automated measurement http://measurement.psy.miami.edu/
