The effect of brief delays to reinforcement on the acquisition of tacts in children with autism

Abstract

We used discrete-trial training to teach 3 children with autism to tact shapes of countries using 3 levels of reinforcement delay for correct responding: 0 s (immediate delivery), 6 s, and 12 s. Two of the 3 participants acquired the targets more quickly in the immediate-delivery condition, suggesting that delays as brief as 6 s may be detrimental to learning tacts for some children.
