Abstract: | A brief experimental analysis was used to compare the effects of the presence of tangible objects in an alone condition following an inconclusive functional analysis of screaming and handmouthing behavior of an 8‐year‐old boy. The alone condition with tangibles involved having toys available throughout the session with no interaction from the therapist and produced a higher percentage of intervals with screaming and handmouthing. The study demonstrates the importance of evaluating the effects of the presence of tangible items during a functional analysis. Copyright © 2004 John Wiley & Sons, Ltd. |
