title: Full house or Pandora's box? The treatment of variability in post-Piagetian research.
abstract: This commentary focuses on the conceptual implications of analyses of individual differences in francophone post-Piagetian research. These analyses are viewed as preoccupied by the "American question" of measurement and method, instead of attempting a theoretical account of the issues raised by intraindividual and interindividual variability in development.
