Further evaluation of the accuracy of reinforcer surveys: A systematic replication

The present report evaluates the accuracy of a reinforcer survey by compari ng the survey results to the results of subsequent reinforcer assessments f or 20 children using a concurrent-operants arrangement to assess relative r einforcer preference. Total accuracy for the survey was determined to be ap proximately 57%. The results provide a systematic replication of Northup et al. (1996) with a much larger sample of children. A need for the developme nt, of more accurate and comprehensive reinforcer assessment methods for ve rbal children is discussed.
