Experiment 1: In a specialized daycare program the use of oral overcorrection (contingent toothbrushing with an oral antiseptic) to suppress one child's thumbsucking at Language Time was found to suppress the behavior of another child who was not treated but who witnessed the target child's treatment. Experiment 2: The main effects of oral overcorrection were replicated. Contingent overcorrection threats (warnings), used independently, were then shown to suppress thumbsucking behavior that had returned to its baseline level. These effects were maintained one month after the threats were discontinued, but they did not generalize to other activity periods, particularly Nap Time. Experiment 3: Contingent threats were found to suppress the persistent nap-time thumbsucking of the child from Expt 2. Increments in certain other (nonoral) inappropriate behaviors were correlated with the suppression of thumbsucking. Threats to use oral overcorrection contingent upon nonoral misbehaviors at Nap Time were not effective. However, the actual use of oral overcorrection for these categories of nonoral misbehavior served to suppress these behaviors. Experimental controls combined treatment reversal and multiple baseline single-subject designs. 相似文献

Forty subjects were assigned to four groups, an External-attending Group, an Internal-attending Group, a Control Group, and a Distracted Group. All groups were presented with six trials of a 0.5-sec 110-db white noise. A measure of heart rate deceleration verified the experimental manipulation of attention. During the anticipatory period, the Internal-attending Group exhibited the greatest and the Distracted Group exhibited the least reactivity among the four groups. The two specially attending groups exhibited greater galvanic skin-response conditioning during the anticipatory period than the other groups. There was no support for the hypothesis that heightened attention facilitates habituation. Two measures were differentially sensitive to direction of attention during the anticipatory period. The External-attending Group exhibited reliably greater anticipatory deceleration of heart rate than the Internal-attending Group, while the Internal-attending Group exhibited reliably more nonspecific electrodermal responses than the External-attending Group. This latter finding, along with other evidence, suggests that an inward direction of attention tends to exacerbate anticipatory anxiety as well as reactivity to the impact of a noxious stimulus. 相似文献
