Thumb sucking in childhood frequently accompanies such other behaviors as holding or manipulating favored objects. This study evaluated the effects on thumb sucking of preventing doll holding in a five-year-old girl who chronically sucked her thumb while holding a doll. A withdrawal (ABAB) experimental design revealed that preventing doll holding eliminated thumb sucking. The results of the study show that preventing a covariant can be an effective, efficient method of controlling thumb sucking.
