Abstract

The effects of a pica exchange procedure were evaluated on the pica of a female with severe mental retardation. A BAB design revealed that the pica exchange procedure was effective at reducing the occurrence of pica. In addition, the pica exchange procedure was effective throughout six increasingly more difficult response effort conditions. Results suggest that extended periods of treatment using successive approximations may overcome initial resistance to increases in response effort.
