The Contingent Use of Trading Stamps in Reducing Truancy: A Case Report.
A contingency contract procedure was used to reduce truancy in a 13-year-old learning-disabled subject. The subject received a daily amount of trading stamps contingent on school attendance. Results showed a significant decrease in truancy from three to four days per week to less than one per week. A reversal design indicated that truancy could be controlled by the contingency procedure.
