Control Transfer

Social participation of children with an autism spectrum disorder (ASD) in natural environments can be enhanced by teaching them to communicate spontaneously, at least in situations where they have the motivation to access specific items or activities by controlling the amount of access for these stimuli. The purpose of this study was to determine if mand training, using a stimulus control transfer procedure would promote acquisition and generalization of mands for specific activities or objects evoked by motivating operations. Measurement variables included the frequency of motivation controlled (MO) versus multiply controlled mands during discrete trial training on a variety of verbal operants. Using a concurrent multiple baseline design across participants, visual analysis indicated that MO mands for out-of-view items increased substantially with generalization across targets, staff, and environments for three of the four participants. One participant did not respond to intervention to the same extent as others.

Visual Shape

Three experiments investigated stimulus control of key pecking in pigeons by varying the distance of vertices movement for a six-point complex visual shape. Ease of discrimination learning was monotonically related to the distance of vertices movement when the directions of vertices movement were held constant. As suggested by selective attention theory, steep generalization gradients were obtained following intradimensional differential training but not following nondifferential training or interdimensional differential training. These results indicate that, unlike the dimension of angular orientation or tilt, distance of vertices movement provides a consistent functional representation of complex shape similarity.

Fading Procedure

A fading procedure similar to that reported by Terrace (1963) was used with monkeys to determine whether errorless discrimination learning could be obtained without prior establishment of a baseline of stimulus control before applying the training procedure. Four methods of training were used which differed with respect to when and how the non-reinforced stimulus (S—) was introduced. No animal learned without errors although all did acquire the discrimination. Furthermore, the fading procedure which was expected to result in errorless learning was no more effective than the other methods. These results suggest that establishing stimulus control before using a fading procedure is a necessary condition for errorless discrimination.
