We used a multiple baseline design across participants to evaluate the effects of teaching 4 typically developing preschoolers to attend to their names and to a group call (referred to as "precursors") on their compliance with typical classroom instructions. We then measured the extent to which the effects on both precursors and…

The behavior of special education students (age 12 and 16) was evaluated as they were presented with 2 academic response alternatives on concurrent reinforcement schedules. Both subjects allocated higher rates of responses to the richer schedule of reinforcement, although only 1 responded exclusively to the richer schedule. (Author/JDD)

In the first study, initial-link responses in a concurrent-chains arrangement resulted in access to terminal links in which the completion of an academic task resulted in (a) the choice of a reinforcer (choice), (b) the delivery of an…
