Teaching children with autism when reward is delayed. The effects of two kinds of marking stimuli.
Three children with autism were taught to identify pictures of emotions in response to their spoken names. Their speed of acquisition was compared using a within-child alternating treatments design across three teaching conditions, each involving a 5 second delay to reinforcement. In the marked-before condition, an instruction encouraged the children to visually orient to the cards before they made their choice response; in the marked-after condition, an attention-eliciting verbal cue (e.g., "Look!") was delivered after both correct and incorrect responses; in the delay condition, these marking cues were omitted. Performance in the no-cue control was inferior to both the marked-before and marked-after conditions, but the difference between the latter two conditions was not significant.
