Chi-Squared (X2) Statistical Test in Rof pain. The 2- to 12-year age range represents two cognitive periods in Piagetian theory: preoperational (2 to 7 years) and concrete operational (8 to 12 years). Research and clinical reports of children’s experiences and descriptions of pain, as well as Piagetian theory, will be used to analyze concepts of pain during these two age periods.
